AMERICAN COLEOPTERA. 155 



surface moderately densely punctulate. Body beneath and legs, moderately 

 densely p\inctured and cinereo-pubescent. Length .44 inch; 11 mm. 

 Male. — Sixth ventral segment slightly emarginate. Metasternum concave. 

 One specimen, Texas. (Belfrage, No. 609). Resembles so much 

 certain of the unicolored forms of cinerea as to be with difficulty dis- 

 tinguished except by the generic characters. 



CANTHARIS, Linn. 



C {Lytta) mutilata, n. sp. — Body black, head and thorax red. Head with 

 very few punctures, epistoma and parts of mouth black. Thorax subpentagonal 

 very little wider than the head, a very fine median line, surface very sparsely 

 punctured. Elytra black, rather finely scabro-punctate, smoother near the base. 

 Body beneath black, moderately shining, sparsely punctate. Legs black more 

 densely punctate. Length .86 inch; 22 ram. 



Male. — Antennae with fifth joint deformed, excavate anteriorly and with the 

 anterior angle slightly prolonged, sixth joint slightly flattened, 7 — 10 oval, 11 

 slightly longer and pointed. Anterior tibise with two spurs, hind tibiae with 

 inner spur slender acute, outer longer, cylindrical and obliquely truncate at tip. 

 Last dorsal segment oval ai tip, fifth ventral truncate, sixth very feebly emar- 

 ginate. Hind trochanters simple. 



Female. — Unknown. 



This species should be placed next to eucera in my revision of the 

 species of this genus. 



For the privilege of studying a perfect male, I am indebted to Mr. 

 Otto Lugger of St. Louis. 



Occurs in Arizona. 



ZONITIS, Fabr. 



Our species are distinguished as follows : 



Eyes lateral, not extending beneath the head ; antennae at most half the length 

 of the body. 

 Legs bicolored. 



Elytra black, head and thorax yellow atripennis Say. 



Body above pale yellow, elytra tipped with black Ilavida Lee. 



Body above pale yellow, elytra with piceous vitta bilineata Say. 



Legs piceous. 



Body above and beneath pale sanguineous rufa Lee. 



Eyes large, extending beneath the head, and comparatively approximated; 

 antennae setaceous, nearly as long as the entire body. 



Thorax and elytra very densely punctured longicornis Horn. 



Thorax and elytra very sparsely punctured vittipeniiis n. sp. 



Z. bilineata may become unicolored, pale yellow, but the elytra are 

 always coarsely punctured. 



Z. Tittipennis, n. sp. — Form elongate, pale yellowish testaceous, moder- 

 ately shining. Antennae nearly as long as the entire body, setaceous, piceous. 

 Head oval deeply but sparsely punctured. Eyes large, coarsely granulated, 

 extending beneath the head. Thorax subcampanulate, not wider than long, 

 disc shining, sparsely and irregularly punctured. Elytra pale yellow, with two
