A New Species of Brachynemurus. 



BY NATHAN BANKS. 



In a small collection of Neuroptera recently sent me for de- 

 termination by Prof. Cockerell, I find a species of ant-lion fly 

 not hitherto described. It belongs to the large genus, Brachy- 

 uonurns, and is allied to our common B '. abdominalis Say. 



Brachynemurus cockerelli n. sp. Face yellow; a large dark brown 

 spot around and between the antennae, lower each side, but with a faint 

 median line toward the clypeus ; vertex yellow, with a brown line each 

 side; antennce brown, moderately long; palpi yellow, last joint partly 

 brown. Prolhorax pale yellow, with four narrow brown lines from base 

 to tip, all of equal width and at equal distances apart ; rest of thorax 

 mostly brown, with yellow spots and lines, two small spots on each 

 anterior lobe of the mesothorax, metathorax pale in the middle ; pleura 

 brown, with yellow spots most numerous on the posterior part of meta- 

 thorax. Legs pale yellow, dotted with black, quite thickly above on 

 hind and middle femora ; tips of tarsal joints brown ; legs with many 

 black bristles, and some white ones on the femora ; spurs as long as the 

 first two tarsal joints. Abdomen yellow, striped with brown, venter 

 mostly brown ; above each segment has a median and a lateral stripe, 

 leaving considerable yellow between them ; the abdomen is clothed with 

 many black and a few white hairs ; in the $ with the third segment nearly 

 twice as long as the fourth. Wings faintly flavescent ; all the longitudinal 

 veins interruptedly brown and white, many cross-veins brown at bases ; 

 no brown on the membrane save a small brown dot at the end of the 

 median in fore wings ; pterostigma yellowish, small and not promi- 

 nent ; wings moderately narrow, hind ones acute at tips ; four cross-veins 

 before origin of the radial sector in fore wings, between anal and cubital 

 veins but one series of cells, few of the costals forked before pterostigma, 

 in fore wing the cubital forks directly below the first fork of the radial 

 sector. Length 31 mm., expanse 62 mm. 



One female from L,one Mountain, New Mexico, July (Cock- 

 erell). Easily separated from B. abdominalis, by the four lines 

 on prothorax, by the dotted median vein in fore wings, and by 

 the lack of spots on the membrane. From //. hubbardi it is 

 distinct by the yellow color, markings of head, etc. 



MR. S. N. DUNNING, of Hartford, Conn., has presented his valuable 

 collection of Hymenoptera to the American Entomological Society. It 

 includes a number of Mr. Dunning's types in this order of insects.
