156 GEO. H. HORN, M. D. 



piceous vittsE on each, one near the suture, the other broader near the side 

 margin, ncitiier attaining the tip or base, surface with coarse shallow punctures 

 becoming more indi^itinct at base. Body beneath colored as above, shining, 

 sparsely punctured ; abdomen densely punctured. Femora yellow tipped with 

 piceous, tibiffi piceous yellow at base, tarsi piceous. Length .40 inch ; 10 mm. 



The body above is sparsely clothed with short, yellowish incon- 

 spicuous hairs, those of the uuder surface are somewhat longer and 

 denser. 



One male, Arizona. 



This species and longicornk may vary in the extent of the piceous 

 elytral vittas. The type of the latter was described as having brown- 

 ish-testaceous elytra, with suture, margin and narrow median stripe 

 paler, but specimens have occurred marked similarly to vittipennis, 

 that is, with the paler color predominating.

CISTEL,.!, Fab. 

 C\ Theveiictii, n. sp. — Piceous. subopaque, form elongate. Head piceous, 

 rufous in front, minutely and densely punctulate. Antennae subserrate, nearly 

 as long as the entire body, piceous, three basal joints rufous, joints two and 

 three short, together but little longer than half the fourth. 'Thorax piceous, 

 minutely and densely punctulate, broader than long, sides regularly arcuate and 

 gradually narrowing to apex. Elytra not wider than the thorax and nearly four 

 times as long, black, striate striae finely punctured, intervals slightly convex, 

 sparsely and very minutely pubescent. Body beneath piceous, more shining 

 than above, sparsely punctulate. Legs pale rufous, tibiae and tarsi somewhat 

 darker. Length ..>0 inch ; 7.5 mm. 



This species belongs to the same group of the genus with opaca and 

 is easily known by its slender form and red legs. 



One specimen Mariposa, Cal., from M. Jules Thevenet. 



C. TariabiliK, n. sp. — Form oval, color variable. Head densely punctured. 

 Antennae half the length of body, slender, second joint half as long as third, 

 the latter as long as the fourth. Thorax broader than long, gradually narrow- 

 ing to apex, surface more densely punctulate than the head, very sparsely 

 pubescent. Elytra oblong oval, minutely punctulate, more shining than the 

 thorax, and with feeble traces of the two inner striae only, surface sparsely 

 cinereo-pubescent. Prosternum beneath rugulose, metasternum smooth at 

 middle, sides sparsely punctured, abdomen shining, sparsely punctulate. 

 Length .20 inch ; 5 mm. 



Somewhat broader than sericea which it otherwise resembles. 

 Varieties in color occur as follows : 



a. — typical, black, thorax red, beneath and legs piceous, the latter some- 

 times red. 

 b. — entirely piceous, varying with paler legs and elytra. 

 c. — entirely testaceous, as in sericea. 



Occurs rather abundantly all over California.
