are minutely and feebly emarginate and generally moderately 

 coarsely faceted, the facets in one group becoming extremel^^ 

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

 stoma simple at apex, except in ivickhami, where it becomes finely 

 beaded. Last joint of the maxillary palpi large, extremely di- 

 lated, bent transversely 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 densely pubescent and 

 sensitive. Antennae 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 coxae are well separated, the posterior 

 still more widel}^ the posterior femora not noticeably dilatetl but 

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

 erect and papillose pubescence ; tibiit^ narrowed toward base, the 

 internal terminal spurs extremely minute and setiform, sometimes 

 apparently obsolete; tarsi moderately long, ver3^ slender, the 

 basal joint greath^ 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 my cabinet may be separated into four groups, 

 as shown by the following table : — 



Eyes extending virtually to the base of the head, the tempera extremely sliort. 

 Eyes moderate in size and coarseness of granulation, the antenna; widely 

 separated at base. 

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



1. calvesceiis 



Elytra rather densely clothed with short fine pubescence, the hairs all 



similar and of equal length ; transverse subbasal impression of the 



pronotum distinct and uninterrupted. (II) 



Eyes separated by fully twice their oami 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 basal third; elytral omoplates rather smaller 

 and more pronounced o. tulierculifei'
