240 AMERICAN COLEOPTERA. 



Las Vegas Hot Springs (Barber and Schwarz). 



The type above described is a male, having the fifth ventral seg- 

 ment broadly subtruncate at apex. In the female the prothorax is 

 a little more narrowed anteriorly, the antennae shorter, the sutural 

 angles of the elytra more acute, and the fifth ventral broadly angu- 

 late at middle. The tibial spurs are slender in both sexes. This 

 species most nearly approaches coviatus, the latter differing in its 

 entirely black legs, more transverse outer joints of antennae, longer 

 more bristling vestiture, more numerous erect black hairs, the punc- 

 tuation of the head and prothorax coarser and closer, and the 

 sutural angle of the elytra evidently rounded. 



T^icliochrotis prosternalis n. sp.— Black, with a feeble oreenisli 

 lustre; legs rufous, anteunse piceous. Pubescence rather sparse, cinereous, erect 

 setfB numerous, long, black throughout; marginal fringe of both thorax and 

 elytra long and bristling, entirely black. Head rather elongate, sparsely punc- 

 tate, frontal impression deeper than usual; eyes not prominent. Antennje 

 strongly incrassate, joints 5-10 increasingly transverse, 11th joint but slightly 

 longer than wide. Prothorax very nearly as long as wide, sides broadly feebly 

 arcuate, slightly sinuate at middle, qiiite strongly convergent from base to apex ; 

 all the angles broadly rounded, side margin distinctly crenulato-serrate through- 

 out; surface finely rather sparsely punctate. Elytra very little wider than the 

 prothorax and twice as long; about one-half longer than wide; punctuation 

 coarse and close. Prosternum very long before the coxse, being about two and 

 one-half times the coxal diameter; tibial spines slender, rather widely spaced, 

 three or four in number; ungual appendages as long as the claws and attached 

 throughout. Length 4.5 mm. 



New Mexico; Mescalero, on Bigelovia graveolens (Cockerell). 



The type is a male, having the fifth ventral truncate, but the 

 tibial spurs are but slightly modified, being slender and acute on 

 all the feet. 



The length of the prosternum is far greater than in any previ- 

 ously described member of the genus and constitutes the most pecu- 

 liar feature of this very distinct species. It should be placed near 

 semdatus in our lists. 



CLERID^. 

 Clems eoralliiius n. sp. 



This name is proposed for a form common in New Mexico which 

 has hitherto passed as a variety of abruptus, but which I am confi- 

 dent w'ill prove distinct. In any case the appearance is so different 

 from typical abruptus that a special name is desirable. The form is 

 as a rule slightly less robust and the punctuation a little finer than
