On July 1, 1893, the writer collected a number of mealy bugs on clover (Trifolium pratense) at Ithaca, N. Y. They were found at about the level of the ground between the several stems of the plant, and also on the roots under the soil. On July 17 of this year the same insect was found on the same plant at Agricultural College, Mich. As they were both supposed to be D. trifolii, Forbes, a comparison was made with the original description.

Antonina Nortoni, Parrott and Ckll.

Sac white, subglobular, cottonlike, completely enveloping female.

♀ oval, plump, cream-coloured, with slight tinge of brown on margin. Boiled in caustic potash, becomes transparent, with the exception of the antennae, the two pairs of spiracles, and ultimate segment, including anal region, which are a dark yellowish-brown. There are many single glands, especially towards and about posterior segments; they are less numerous anteriorly. On outer side of each spiracle there is a crescentic group of rather large circular glands, placed very close together. Antennae aborted, short, thick, composed of three segments measuring respectively 18–25, 13–16 and 27-28 mm. Mouth-parts large Spiracles chitinous, large and extended. Anal orifice circular, situated in a depression, surrounded by a strong chitinous ring. Anal ring with six long, stout hairs measuring from 53 to 89 mm. in length.

The following is a list of the species of these two groups occurring in California, with notes on those forms knows to me:

Habropoda, Smith.

A small group of bees, comparatively local in their habits, and in appearance very much like the larger species of Anthophora.

Egg.—A little less than spherical, the base flat. Twelve sharp ribs run to the vertex, which is large, circular, reticulate, with a central elevation at the micropyle; one-third of the way down these ribs neatly alternate with twelve others, forming twenty-four ribs around the base. Ribs straight; space distinctly, regularly cross striate. Diameter .8, height .7 mm.

Stage I.—Head rounded, mouth pointed; shining yellowish; width .5 mm. Body thickened at thorax and joint 12, robust, sharply tapering at joint 13, which is placed almost under joint 12. Translucent yellowish, shining and sticky like a slug, the food showing by transparency. Setae minute and pale, not glandular, tubercles obsolete. Rests curled on the back of the leaf; several larvae on the same leaf, but not gregarious. Hatched when found.

On the 21st of July, Mr. E. Denny, who often accompanies me on my entomological rambles, brought me a cyanide bottle full of butterflies which he had collected for amusement's sake. On looking at it I immediately saw a specimen that was new to me, and was congratulating myself on getting what I thought would be a new addition to the Satyrinae of my collection. My pleasure was increased, on consulting Dr. Holland's “Butterfly Book,” to find it was a Chlorippe celtis, Boisd.-Lec., ♀. or Hackberry butterfly. (Plate XXIII., fig. 4.) A species, he states, as found generally from southern Pennsylvania, Ohio, Indiana, and Illinois, to the Gulf of Mexico. I immediately called my friend's attention to the specimen, and he remembered the particular place he had found it, because he thought at the time it was something he had not seen in my collection. So ever since we have watched the locality, but have not been successful in obtaining another. It was caught in the Outremont district, just outside the city limits of Montreal.

Cirrophanus Dyari, n. sp. — ♀. Expanse 34 millim. General colour and markings just as in C. triangulifer, Grote, except as regards the following particulars: The general colour is more ochreous — not so orange; the t. p. line curves inwards to a point not far from the middle of the wing, whence it rapidly bends outwards for a short distance, after which it again bends downwards and inwards to the inferior margin; the s. t. line is further from the margin, and deeply shaded about the middle with ochreous; the oblique dark line from the lower part of the t. p. line to the costa is distinct, and has a sharp zigzag near its middle. It results from the direction of the t. p. line that the light patch at the anal angle is more extensive than in C. triangulifer, but it is broken by a dark shade representing the lower part of the s. t. line. Hind wings strongly suffused with gray, with a curved gray line crossing the middle. Thoracic tufts deep brownish-orange. On the under side the primaries, except their margins, are strongly shaded with blackish.

H. hormos is not uncommon on the persimmon in Alexandria County, Virginia. The species is double-brooded.

Egg. — Less than hemispherical, domed; ribbed with about 48 ribs around the margin, rather low, distinct, diminishing by confluence in pairs toward vertex, very slightly waved. Cross striae faint lines crossing the hollows, scarcely indicated on the ribs. Micropyle somewhat broadly finely rouncled reticular, not ridged. Diameler .6 mm.

Having brought my studies of the neuration of the diurnals to a preliminary close, I wish to place on record here the conclusions to which they have led. The diphylism is founded on the following characters:

A.–Butterflies having a short third anal vein on fore wings, curving downwardly from base to internal margin, and with only one anal vein on hind wings ......... Papilionides.

B.–Butterflies having a fork to the second anal vein of fore wings at base, sometimes incomplete, often disappearing through absorption, and with at least two anal veins on hind wings ......... Hesperiades.

The wasps belonging in this family have a peculiar habitus quite their own. The head is always wider than the thorax, the front wings have three cubital cells, while the abdomen, in nearly all the species, has usually a strong constriction between the first and second segments, the first segment being most frequently much narrowed. In only a single genus, Trachypus, Klug., is the abdomen distinctly petiolated. The eyes are large and normal, but occasionally exhibit a slight emargination within, and, more rarely, with a distinct emargination, or reniform as in Trypoxylon and Pison. Most of the species have the abdomen strongly punctured or punctate, and have also a constriction between all the abdominal sutures, although some also have the abdomen smooth and polished, and are without a constriction at the sutures.

Among the interesting species of Heteroptera which have been sent to the Division of Entomology by correspondents during the present season was a species of Tingitidae which has not hitherto been described. In accordance with an established custom of the the U. S. Department of Agriculture, the following description is submitted for publication in a periodical journal in preference to publishing it in a Departmental bulletin. Gargaphia angulata, n. sp.
