AMERICAN COLEOPTERA. 229 



C ans;iista>ta. Spin. — Pale brown, form rather slender, body apterous, 

 surface sparsely pubescent, elytra with three indistinct, paler transverse fasciae. 

 Head rather coarsely and densely punctured, eyes feebly prominent. Antennae 

 ferruginous, nearly half the length of body.. Thorax one-third longer than, 

 wide, very feebly constricted in front of and behind the middle, base some- 

 what narrower than apex with distinct ante-scutellar impression and a tubercle 

 on each side, surface densely and coarsely punctured. Scutellum transversely 

 oval. Elytra very little wider at base than the thorax, humeri feeble, sides 

 feebly arcuate and slightly diverging to apex, tips separately rounded, disc 

 with rows of coarse punctures which gradually become more distant and some- 

 what smaller to apical fourth. Body beneath and legs paler, sparsely punc- 

 tate. Length .30 — .44 inch ; 7.5 — 11 mm. 



Male. — Fifth ventral deeply emarginate, sixth elongate, sides nearly parallel 

 with the tip, deeply emarginate, the angles prolonged, obtuse. Last dorsal ob- 

 oval, tip with a small acute notch limited on each side by a small acute tooth; 

 penultimate dorsal broadly triangularly emarginate. (PI. I, fig. 16). 



Female. — Fifth ventral feebly emarginate, sixth broadly oval at tip. Last 

 dorsal more elongate oval. 



Occurs at Fort Yuma and elsewhere in the south of California. It 

 is more coarsely punctured than ovipeunis, with less oval elytra and 

 different male characters. 



C. ovipciiuis. Lee. — Pale brown, elytra with indistinct median pale fascia. 

 Head densely punctured, eyes moderately prominent. Antennae ferruginous, 

 nearly half the length of body. Thorax one-half longer than wide, rather 

 strongly constricted in front of middle and strongly compressed posteriorly, 

 ante-scutellar impression rather strong with a tubercle on each side, surface 

 sparsely punctured, Scutellum oval. Elytra scarcely wider at base than the 

 thorax, sides moderately arcuate and divergent posteriorly, apices conjointly 

 rounded, disc with striae of coarse punctures extending to middle, the outer 

 striae longer. Body beaeath paler, very sparsely punctate. Length .34 — .44 

 inch; 8.5 — 11 mm. 



Male. — Fifth ventral moderately emarginate, sixth very deeply emarginate 

 with the angles prolonged; penultimate dorsal feebly emarginate, last dorsal 

 longer than wide, truncate at tip with a long acute notch. (PL I, fig. 17). 



Female. — Last ventral semicircular, last dorsal subtruncate at tip. 



The males of this species show a very feeble truncation of the tips 

 of the elytra, which might readily escape notice. 



Occurs at Fort Tejon, California, and is not rare. The elytra are 

 more decidedly oval than in angustata^ and the male characters 

 sufficiently different. 



C. pUoaella, Lee, is founded on two small females, which agree in 

 all the important characters with ovijicnnis, the above description 

 applying equally to this except as to size, (.26 inch). I do not feel 

 warranted in continuing it as a di.stinct species, but the discovery of a 

 corresponding male may lead to different results.
