are minutely and feebly emarginate and generally moderately 

 coarsely faceted, the facets in one group becoming extremely 

 large, however. The epistomal suture is distinct and the epi- 

 stoma simple at apex, except in ivickhaini, where it becomes iinely 

 beaded. Last joint of the maxillar}' palpi large, extremely' di- 

 lated, bent transverselj' on its compressed side in the form of a 

 bow, with the basal angle broadly obtuse, that of the labial 

 moderate in size, thick, the apex truncate in the form of a flat cir- 

 cular or inwardly pointed disk, which is densel}' pubescent and 

 sensitive. Antennne moderate in length and thickness, gradually 

 and generally feebly incrassate, the third joint much longer than 

 the fourth, the second small, eleventh moderate in size, conoidal 

 and normal. The middle coxa? are well separated, the posterior 

 still more widely, the posterior femora not noticeably dilated but 

 having beneath in both sexes an elongate area, clothed with dense 

 erect and papillose pubescence ; tibiiij narrowed toward base, the 

 internal terminal spurs extremely minute and setiform, sometimes 

 apparently obsolete; tarsi moderately long, very slender, the 

 basal joint greatly elongate. Abdomen with the basal segment 

 very large, without trace of dividing suture, the fourth much 

 longer than the third. Prothorax narrowed in front, generally 

 transversely impressed on the disk near the base. Scutellum 

 small, narrowly trapezoidal. Elytra oblong-oval, the flanks rather 

 abruptly vertical. Sexual characters not determined and ap- 

 parently extremely feeble. 



The species in ray cabinet ma}^ be separated into four groups, 

 as shown by the following table : — 



Eyes extending virtually to the base of the head, the tenipoia extremely short. 

 Eyes moderate in size and coarseness of ^lanulation, tlie antennaj widely 

 separated at base. 

 Elytra clotlied sparsely with very short, coarse and decumbent hairs. (I) 



1. calvescens 



Elytra rather densely clothed Avith short line pubescence, the hairs all 



similar and of e(iual length ; transverse subbasal impression of the 



pronotum distinct and uninterrupted. ( 11) 



Eyes separated by fully twice their own width, the vertex flatter and 



densely punctate. 



Larger species, the transverse impression of the pronotum feeble in 



profile and very near the base 2. piceus 



Smaller, the transverse impression deeper and larger in profile, oc- 

 cupying more than ba.sal third; elytral omoplates rather smaller 

 and more pronounced :?• tuberculifer
