SPECIES OF BRACHYCISTIS (FAM. MYRMOSID^E) FROM 



SOUTHERN CALIFORNIA. 



BY T. D. A. COCKERELL, EAST LAS VEGAS, N. M. 



Brachycistis gaudii, n. sp. — <$ . Length about 6}4 mm.; shining 

 black, brown on prothorax, at bases of wings, and at extreme (usually 

 covered) bases of abdominal segments ; antennae long, dull reddish- 

 brown, first joint of liagellum equal to second ; head broader than thorax ; 

 eyes very prominent ; ocelli in an equilateral triangle, the area between 

 them elevated : edge of clypeus, and mandibles, dark ferruginous, the 

 latter tridentate ; mesothorax shining, hairs and punctures very sparse ; 

 metathorax minutely transversely lineolate ; tegulae light ferruginous ; 

 wings hyaline, iridescent, nervures pale except the costal, stigma large, 

 dark brown ; three submarginal cells and two recurrent nervures, the 

 second recurrent sometimes failing below ; marginal cell extremely short, 

 broader than long, its greatest diameter about half length of stigma ; 

 first submarginal large, extending along stigma to marginal ; second 

 submarginal minute, triangular, entirely cut off from marginal ; third 

 submarginal minute, long and narrow, its tip reaching marginal ; first 

 recurrent nervure joining first transverso-cubital, second joining third 

 submarginal cell near its base ; abdomen shining, very sparsely 

 punctured, with long sparse yellowish hairs ; first segment swollen, about 

 twice as long as broad, with a deep constriction between it and the 

 second ; apical curved spine long, ferruginous ; legs black, knees, apices 

 of tibiae and tarsi light brown. 



Hab. — -La Jolla, San Diego Co., California, at light, Aug., 1901. 

 3 £ . Allied to B. elegant ulus, but different in colour, and the venation 

 is not quite the same. Also related to B. contiguus, Fox, but the middle 

 segment is not finely punctured posteriorly, and the venation differs. 



Brachycistis carinatus, Fox, 1899. — San Pedro, Cal., July 9 ; La 

 lolla, Cal., August. Three males. The eyes are black, not pale 

 castaneous as Fox describes ; perhaps his specimen had been in alcohol. 

 This insect comes to lights at night, and represents B. glabreilus on the 

 coast of Southern California. It was hitherto known from one example, 

 vaguely said to be from California. 



We regret to record the death of Mr. P. C. Truman, of Volga, South 

 Dakota, which occurred on the 27th of October, the result of an attack of 

 pneumonia. He began collecting insects about seventeen years ago, 

 and by diligent work succeeded in forming what is considered to be the 

 finest collection of Lepidoptera in the North-western States, and also a 

 good collection of Coleoptera. 



Mailed December 10th, 1901.
