Noctua dislocata, n. sp.— Ground colour bluish, ash-gray, marked and more or less suffused with reddish. Head gray, tending to reddish on the vertex; palpi deep brown at the sides. Thorax mouse at fawn gray or reddish, immaculate. Primaries in a general way are gray to the middle of the wing and reddish beyond; but they may be an even reddish-gray throughout. All the normal maculation is present, but not contrasting. Basal line geminate; but the outer line is obscure and only the inner is dark brown and obvious. T. a. line narrow, brown, single, preceded by a narrow paler line, just a little outcurved between the veins and a little outcurved as a whole.

Near Monument Creek, Colorado Spirngs, my wife and I recently came across an undetermined species of Artemisia, about three feet high, bearing many Cecidomyiid galls. The flies emerged these galls on April 2, and as the species is new, it is herewith described:

Diplosis Coloradella n. sp.—♂. Length hardly 2 mm. Head black; thorax black, reddish posteriorly mesothorax with rows of black bristles; legs reddish-brown, suffused with dusky; abdomen narrow, reddish passing into yellowish, with long lateral hairs, genitalia darker, terminal joint of forceps stout; wings with a very long fringe; first vein reaching costa about or very slightly below middle of wing; third vein reaching the margin at the apex of the wing, but the apex is subtruncate, rather bulging below, so that the most distal point seems a little below the end of the vein; fifth vein forked beyond its middle, but its distal half reduced to mere shadowy lines; antennæ reddish, 15 (2+13) jointed, joints cylindrical, slightly constricted in the middle, pedicillate with very long hairs, terminal joint subacuminate.

The species here treated belong to genera previously “lumped” under Andrena.

Three submarginal cells.

♀ with joint 3 of the antennæ shorter than 4 and 5; ♂ with joint 3 shorter than 5, rarely as lon gas 4; sculpture in both sexes with few exceptions coarse, enclosure usually ridge, depressions fo abdominal segment usually sharply defined; ♀ with a simple tibial.

By a recent article in this Journal giving the life-history of Sabulodes arcasaria, Walk., Dr. Otto Seifert demonstrates the need of careful study of some of our species of Geometridæ. A similar case has come under my notice. In June, 1896, I gathered in beating ten rough-looking mahogony-red larvæ from a small group of oaks(Quercus nigra). They were exactly alike in form and colour, and apparently well-grown, so I carried them home, supposing they would quickly mature. They had no thought of it.

The Ray Spiders live a retired life along the banks of some creek, where overhanging bushes and projecting rocks afford the gloom which they seem to seek. In such locations, especially in the dark recesses under clusters of roots, we may look for their cocoons in midsummer. They are among the most interesting to be found—little golden-brown balls, about one-eighth of an inch in diameter, suspended by a single glossy-white thread nearly an inch long.

With the opening of the season, my son, Kenneth R. Stevenson, has proceeded to keep up his reputation as a Coleopterist by finding two specimens of Aphodius erraticus, Linn., on the first of May under stones on a waste piece of ground in Maplewood, near Montreal.

In order to avoid needless repetition, I wish here to express my sincere thanks to Prof. John B. Smith and Dr. H. G. Dyar for numerous favours, and also to Mr. O. C. Poling for his great liberality in furnishing me with many of the species here described. Mr. Poling has made a number of collecting trips to little known parts of Arizona and Utah, and in addition to many new species has turned up many rare forms discovered years ago by Morrison and Doll. The fauna of Southern Arizona is essentially Mexican, and as there is at present no collection of Mexican Lepidoptera in this country worth mentioning, one in describing apparently new species from that region is certain to make synonyms.

In Lycosa there is in most cases present a small, apically more or less rounded flap or lobe at and pressing against the base of origin of the embolus. This lobe, which may be spoken of as the palea, is often small or but weakly developed; but in L. pulchara it is very long and conspicuous. Here it embraces and supports the embolus along much of its length, being at the same time shifted ectad from its usual position. This special development of the supporting palea in L. pulchra is associated with the pecuilar position of the embolus, which instead of curving back to rest along the lectus in the ususal manner, here arches foward and outward (i. e., ventrad) free from the bulb, only its apical part, which turns forward and rests obliquely across the auricula, being at all in contact with the lectus.
