242 MEMOIRS ON THE COLEOPTERA 



rufo-piceous, the three basal joints testaceous; prothorax rufous, wider 

 than the head, slightly shorter than wide, quadrate; apex slightly sinuate, 

 with the angles rounded; sides rounded, slightly converging posteriorly; 

 base truncate, oblique at the sides, with the angles obtuse, not rounded; 

 surface slightly convex, the anterior transverse impression somewhat 

 distinct, arcuate, remote from the apex, the longitudinal stria entire; 

 foveae rounded, densely punctate; elytra rather flat, parallel, rounded at 

 apex, slightly wider than the prothorax, more than twice as long as wide, 

 rufo-piceous, shining, the margin finely and the suture rufous, striate, 

 the scutellar stria long, straight; intervals convex; under surface rufo- 

 piceous; epipleura and legs testaceous. Length 4.25 mm.; width 1.5 mm.

Mr. Fall, who examined the type in the LeConte collection, 

 intimates (N. Y. Journ., 1905, p. 171) that this species cannot be 

 referred to the present genus, as it closely resembles Bradycellus 

 rupestris and may possibly not differ from it specifically. But this 

 conclusion is probably due to hasty or inaccurate observation, 

 as the description clearly indicates that the scutellar stria is well 

 developed; it is wholly obsolete in rupestris and allied species. 

 This is a very important point which demands further comparative 

 study of the type. 



Catharellus n. gen. 



The only known species of this genus resembles those of Steno- 

 cellus in habitus, but differs in some important features. The 

 body is similarly elongate, parallel and moderately convex, differing 

 thus from the more ventricose outline of Bradycellus, but there is 

 no trace of the important annular fovea at the base of each elytron, 

 nor of the basal punctate impressions of the pronotum. The 

 emargination of the mentum is moderately shallow, with a distinct 

 and acutely angular tooth. The labial palpi are rather slender, 

 the second and third joints equal in length, the former convex, 

 cylindro-oval and certainly bearing three setae, one on the inner and 

 one on the anterior side at apex and one on the anterior side behind 

 the middle, the third joint is rapidly subulate at tip as in Brady- 

 cellus and, in the male, has a large rounded cavity medially. This 

 impression seems to affect the males of most species of the Acupal- 

 pini, as discovered by Horn, but I have also occasionally noted it to 

 some extent in females, whether it is due in part at least to post- 

 mortem contraction or not I cannot say. The type may be de- 

 scribed as follows:
