THE CANADIAN ENTOMOLOGIST. 411 



Rostrum not reaching to the middle coxse. Pronotum truncate behind. 

 Tegmina with the lateral margins comparatively subparallel. Hind tibiae 

 straight, not pilose. 



Length, 8 mill.; width, 2 mill. 



Hab. : Peru, Callanga. 



9. Trimoncopeltns simulans = Lygdus simula?is. — Distant, 1883, B. 

 C. A., Het., I, 242, PL 24, f. 16. 



Hab.: Peru, Marpacalla. 



Distant's figure and description are both poor. The sulcation of the 

 head is of the feeblest kind ; the pronotal callosities are well marked and 

 contiguous, almost forming a second collar. The cuneal notch is not 

 profound. There is no hamus in the wing-cell. The membrane is 

 unicolorous, var. atrior nov. Tegmina black, except a long-triangular 

 spot near the apex of the clavus interiorly, lateral margiris of corium, basal 

 two-thirds of cuneus, etc , whitish-yellow. Size and locality of the type- 

 form as above. 



Fam. Issidae. 



10. Eurybrachys tomeiitosa (Fabr.). — ^Malabar Coast, Mahe. 

 The hind femora and tibice are concolorous, sanguineous. 



THE IDENTITY OF BREPHOS CALIFORNICUS AND B. 



MELANIS. 



BY HARRISON G. DYAR, WASHINGTON, D. C. 



Professor Smith attempts to identify these species with forms of 



Leptarctia, and states that his series is not sufhcient to enable him to 



exactly match Boisduval's descriptions. The descriptions can be fairly 



well matched in specimens before me in the collection of the National 



Museum, californicus corresponding to a form that we have under typical 



californice, Walker ; vielanis to darker specimens of dimidiata, Stretch. 



As no two of the eighty specimens before me are alike, it seems scarcely 

 necessary to insist on exactly matching the descriptions. In short, I see 

 no objection to this identification, except the rather serious one that 

 Boisduval, in the same publication in which he described the species of 

 Brephos, also described the Leptarctia, three forms, as Lithosia decia, L. 

 lena and L. adtiata. Is it to be supposed that so good a Lepidopterist as 

 Boisduval would describe the same species thrice as a Lithosian and twice 

 as a Brephos in the same paper ? Possibly so ; but this seems doubtful, 

 and it may be better to hold the Brephos names on our lists for a while, 

 much as we should like to dispose of them in the way suggested by 

 Professor Smith.
