NEW MUTILLIDyE FROM CALIFORNIA. 



By T. D. a. Cockerell. 



During a recent visit to California I obtained a number of 

 Mutillidae, among which I find three undescribed species. 



Dasymutilla aletina, n. sp. 



<? . Length about 8 mm., slender, integument entirely black ; 

 top of head, mesothorax and scutellum, abdomen above beyond basal 

 third of second segment, and sides of segments 3 to 5 below, with 

 very long, erect, very bright red hair, with a distinct crimson tint, 

 and no appressed hair at its base ; rest of hair on head and body, and 

 that on legs, black; mandibles bidentate, not enlarged ; clypeus with 

 a median projection on lower margin ; eyes nearly spherical, not at 

 all emarginate, minutely facetted ; ocelli small ; mesothorax coarsely 

 and strongly punctured ; metathorax rounded, dull, very coarsely 

 cancellate ; tegulae piceous ; wings black, slightly pallid in the region 

 of the marginal and submarginal cells ; second submarginal cell not 

 narrowed to a point above ; first abdominal segment nodose, very 

 coarsely and densely punctured, the suture between it and second 

 deeply constricted, ventral keel ending in a sharp tooth which pro- 

 jects downward and backward ; second ventral segment strongly 

 punctured, but flattened and scarcely punctured in middle, the 

 following ventral segments punctured only along hind margin, 



Hab. — Avalon, Catalina Island, California, middle of August, 

 1915 (Aleta Venahle d Hazel Andrews). Allied to D. coccineo- 

 hirta, Blake, but differing in the venation, the entirely black 

 tegument, and the small and slender form. 



Dasymutilla snmneriella, n. sp. 



2 . Length about 9-5 mm. ; moderately robust, the thorax con- 

 spicuously narrower than the abdomen, the head scarcely as wide as 

 the thorax; eyes nearly circular, smooth and shining; first abdominal 

 segment broad, sessile on the second ; upper part of head, including 

 cheeks and front, and dorsal surface of thorax and abdomen, with 

 the tegument red, and this closely covered with erect and appressed
