Every collection of western Bythoscopidæ that the author has Examined has had a more or less heterogeneous assemblage of forms closely resembling Idiocerus alternatus. These have been somewhat Indiscriminately divided between alternates, ramentosus and several MS names of Uhler‖s in classification, or not determined at all. At the time of publication of the key to this genus, the material at hand was not sufficient to warrant the descriptions of these forms, and they were omitted. Since then the author has paid special attention to the collecting of this, group in Colorado, and has received a long series of specimens from the Pacific Coast, mainly from the collection of Mr. C. Livingstone. With this material it has been possible to accurately define a number of these species and clear up much of the obscurity in this section of the genus. During the progress of this study several other new species and varieties have been described, and are also presented here.

Through the great kindness of a friend, I have received cocoons of Callosamia angulifera. These are stemless, and at once distinguishable from those of C. promethea. This character bears out the theory (see Can. Ent. for April, p. 94) that C.angulifera is the older, more generalized form in the genus. In my work on the Saturnians, June, 1896, I tried to show that the stemmed cocoons of Philosamia, Attacus and C. promethea were specializations and a more modern development, and gave probable reasons for acquirement of the habit of fixing the cocoon to the branches, so that it might not fall with the leaf in the autumn(1.c., pp. 15–16; also Plate 1.)

Phenacoccus cevalliæ, n. sp.

♀. Oval, 4 to 5 mm. long, pale olive green, but covered with white secretion, with lateral tassels and thick caudal tassels; placed in alcohol, they stain the liquid pale green; alcoholic specimens appear strongly segmented, with two longitudinal blackish bands, best marked in rather immature specimens. Eyes prominent; skin with many small circular glands; the lateral patches consist of about twelve glands each, but are without spines; a few rather large bristles scattered about the body; legs and antennæ reddish-yellow; denticle on inner side of claw rudimentary, just visible; antennæ 9-jointed, the club 2-jointed. Measurments of antennæ and legs in μ: Anterior legs, femur and trochanter 470, tibia 330, tarsus 130; hind legs, femur and trochanter 540, tibia 440, tarsus 135.

As has been shown by several previous writers, the Synopsis published in instalments by Fieber, in Lotos, Volrtme III., all appeared on or before August 1853. Such being the case, all his new generic names have precedence over those of L. H. Fischer,* the preface of whose work bears the date, November, 1853, and which is unlikely to have appeared before 1854.

D. anomalus, Robt. Specimens from Dr. Granicher, collected at Milwaukee, wwere examined.

D. occidentalis, n. n. for D. anomalus, Ckll.

Ann and Mag. Nat. Hist., Ser. 7, VII, 126 (Jan., 1901).

This differs from the true anomalus in its large size, more densely punctured mesothorax, finer and more numerous lines on the metathorax, dark tegulæ, abdomen distinctly punctured, quite closely on the second segment; denser pubescence on the abdomen nearly concealing the surface on the apical segments; apical margins of abdominal segmentgs testaceous.

The following species of Semioscopis (Epigraphia) seem undescribed. They were sent for names by Messers. F.A. and H.D. Merrick, of New Brighton, Pennsylvania, and have donated by them to the National Museum. These new species closely resemble several of the European ones, yet seem all specifically separable.

Glossa lanceolate shorter than menturn; paraglossæ reaching to joint 4 of labial palpi; maxillary palpi six-jointed, longer than lamina, joints short 5 labial palpi with joints subequal, first one robust; marginal cell about as long as first discoidal, obliquely truncate, appendiculate; cubital cells equal, second receiving the first recurrent nervure about one-third from base and the second near apex; facial foveæ present in both sexes; tibial scopa of female thin, with rather long simple hairs.

Coelioxys Foxii, n. sp.

Coelioxys vigilans, Fox, not Sm. Tr. Am. Ent. Soc, XVIII., 344, 1891, ♀ ♂.

Conspicuous by its deeply-punctured thoracic dorsum and the orange to yellowish pubescence.

♀ Length, 10.5 mm. Clypeus rugose, with close, large, poorly defined punctures, covered with a fine whitish pubescence, and having a whitish moustache; sides of the face covered with a yellowish appressed pubescence; near the ocelli this becomes erect; around the latter the hairs and dark brown, and form and erect fringe; a raised space in front a auterior ocellus, tapering down in front to a point terminating between insertion of antennæ, has longitudinal impressed line along the middle on its lower half, and branches up to each side of the anterior ocellus impunctate, dullish, the space between and surrounding punctured; an impunctate space between lateral ocelli and eye margins; top of the head punctured, dullish, the punctures smaller than those on dorsulum, almost bare; cheeks with appressed pubescence paler than that on sides of face.
