108 THE CANADIAN ENTOMOLOGIST. 



coarse punctuation, also by the shorter and outwardly more incrassate 

 antennae. I have specimens from California (S. Francisco, S. Barbara, 

 Pacific Grove and Point Reyes) ; also from Oregon (Newport), the latter 

 being co-types of 6^. nigerrima Brnhr. i. litt. My Pacific Grove specimens 

 were taken near the ocean, on a moist, thickly-incrusted salt flat, under 

 cow manure ; and I have no doubt that crebrepundata is exclusively a 

 seashore-inhabiting species. 



8. atrolucens Csy. — Closely related to (if not identical with), Gnypeta 

 cœriilea Shalb. from Northern Europe, differing chiefly from the latter by 

 the more shining integuments. Occurs in the mountainous regions of the 

 Eastern United States (Catskill Mts. in N. Y.; Mt. Washington in N. H.). 

 My 5 specimens from Mt. Washington are, curiously enough, all males, 

 and I have in my collection another male from Vermont. The type of 

 atrolucens is said to be a female. 



9. luceîis Brnhr. — A synonym oi laticollis Csy. 



10. heleiice Csy. — A good species of the carboiiaria-i'ipicola group, 

 with a well-marked, bifoveate antebasal transverse impression on the pro- 

 thorax. In the male the head impressed, the bottom of the impression 

 impunctate, the prothorax not modified, the 6th ventrite produced and, at 

 the tip, moderately rounded. A species of wide distribution. I have 

 before me specimens from Montana (Kalispell); N. Dakota (Williston); 

 Colorado (Buena Vista) ; Nevada (Reno) ; Arizona (Williams), and Cali- 

 fornia (Occidental, Deer Park Springs, Tahoe City and Tallac). My 

 Tahoe City specimens were taken in a swampy place ; they appeared to 

 feed on dead tadpoles ; other specimens from the same locality were taken 

 during the evening flight. 



11. deserticola Csy. — Smaller, with paler legs than helence Csy., but 

 otherwise scarcely different, and probably a synonym of the latter. I have 

 not seen this form. 



12. puncitdata Csy. — Still smaller than deserticoia, placed at present 

 also as a synonym of helenœ Csy. I refer to this form a specimen of the 

 Fall cabinet (from Pomona, Cal.) ; another specimen from Pasadena, Cal., 

 is more shining, with more sparsely punctate abdomen, but otherwise not 

 different. 



13. ve?itralis Csy. — One specimen in my collection from Arizona 

 (Williams), agrees fairly well with the original description, but appears to 

 be quite similar to majusciila Csy. also, judging from the description ; no 

 opinion can be pronounced about the status of this species until more 

 material is accumulated in our collections.
