THE CANADIAN ENTOMOLOGIST. 249 



The above species was suppressed as a synonym oî ege?ius hy Dr. 

 Horn in his monograph without explanation or remarks, and it seems to 

 be entirely unwarranted. In making an examination of the egenus series 

 in the Le Conte collection at Cambridge, I was much surprised to find 

 that the specimen bearing the label ''A. cepJialicus Lee." (and also '^ege?i7is 

 No. ii") belonged to a different group, having the antennte serrate from 

 the fourth joint. Numbers 3, 5 and 16 were also this species, and there 

 were seven specimens having the fourth joint serrate and the inner lobe 

 of the claws incurved ; these are probably otiosus. The type o{ puncticeps 

 Lee, which has the fourth joint serrate, is placed as No. 13 in the ege?ius 

 series. This was also made a synonym of egenus by Dr. Horn. The 

 exact standing oî puncticeps is at present doubtful ; I was inclined to place 

 it in the otiosus group, although I was unable to see the claws of the mid- 

 dle tarsi, which were the only ones intact ; but since reading Le Conte's 

 synopsis, in which he places it in the group with the inner lobe of the claws 

 contiguous, I consider it to be a valid species. If it should prove to be 

 identical with cephalicus, the n-àmt puncticeps will have priority. 



The Le Conte specimen bearing the label cephalicus is a female, and 

 I have prepared the following re-description from five males from High- 

 spire, Pa., June 12 to 20, 1909, and June 14, 19 10, all collected by Mr. 

 W. S. Fisher, of that place. He also sent me two males from Jean- 

 nette, Pa. 



A. cephalicus Lee. Re-description: Form of otiosus; colour 

 seneous-olive. Anten?ice moderate, bluish «neous, serrate from the fourth 

 joint, second and third joints with rather long pubescence on the under 

 side. Head convex, bluish, median line varying from distinctly to faintly 

 impressed, and extending to a post-clypeal pubescent area, sparsely 

 punctate, finely alutaceous, strigate on the occiput. Prothorax a little 

 wider than long, narrowed at the base, sides feebly arcuate, lateral 

 margin nearly straight, hind angles with a well defined carina, disk 

 convex, subequally bi-impressed on the median line, an oblique lateral 

 depression; surface transversely strigate, strig^ becoming confused anter- 

 iorly. Scutellum transversely carinate. Elytra subparallel, narrowed at 

 the apical third to the rounded serrulate apices j disk flattened, faintly 

 costate ; surface densely imbricate, basal impressions moderate. Body 

 beneath bluish varying to greenish aeneous. Proster?ial lobe distinctly 

 emarginate and covered with an erect grayish pubescence, or hair, that 

 extends to near the middle of the first ventral segment; it is shorter and 

 less noticeable on the metasternum ; tip of the intercoxal process of pros-
