236 ASHMEAD [ 2 3O] 



hind trochanters, basis of their tibia?, the tarsnl joints more or less 

 basally, and the first ventral abdominal segment and along the sutures 

 of the second pale yellowish. Wings hyaline, the costas brown-black, 

 the stigma and internal veins brown. 



The antemuc are 24-jointcd, about as long as the body, filiform, 

 brown-black ; the first two joints of the flagellum are subequal, about 

 j ' J times as long as thick, the following to the last very gradually and 

 imperceptibly shortening, the penultimate being very little longer than 

 thick, the last fusiform, nearly as long as the two preceding united. 

 Mi tathorux smooth, shining, at the most feebly aciculate posteriorly, 

 the apical transverse and the pleural carinae distinct. Abdomen, ex- 

 cept the first segment, and the second feebly at base, smooth and 

 shining, the first longitudinally aciculate, the second feebly and faintly 

 aciculate at base only. 



Type. Cat. No. 5675, U. S. Nat. Museum. From Popof Island, 

 July 10; St. Paul Island, August 24 (Fur Seal Commission).

From Sitka. Very common in the mountains of California. 



Mr. Davis is clearly wrong, in making this species, and others, 

 noted above, synonymous with Op/lion marginatus Say, a species he 

 never saw and which from Say's description cannot possibly belong to 

 this genus. Long after his original description was published, Say 

 wrote, u This species is very remarkable by the prominence of the 

 head in front of the insertion of the antemue which hence appear to 

 be situated in a deep foveola ; this character, together with the very 

 short, robust feet proves a close relationship to Alomva to which in 

 fact I \\ould refer the species, but that there is no appearance of a 

 Second cubital cellule f tin- an lemur have j6 joints." (Italics mine.) 



Tapinops califm-nicus Ashmead lias an areolet or second cubital cell 

 and the antenna' have only 29 joints. Davis evidently overlooks this 

 note on Sa\ 's species. 



I have rei-ogni/.ed Sas's species; it does not even belong to this 

 tribe, hut belongs to a genus in the next tribe or the Exochini.
