where it is in close contact with the prothoras, the vertex flat; 

 epistomal suture fine but distinct. p]yes L^rge, coarsel}' faceted, 

 distinctl}^ pilose, occup3ing the entire sides of the head and 

 touching the prothorax at base, having a small but distinct an- 

 terior notch. Antennae moderate in length, distinctly and grad- 

 ually incrassate. Last joint of the maxillary palpi moderate in 

 size, short, transverse, the basal angle broadl}^ obtuse, that of the 

 labial transversely excavated at apex and well developed. Scu- 

 tellum rather large, equilatero-triangular, narrowly truncate at 

 apex. Middle coxse moderately separated, the posterior a little 

 more widely. Abdomen with the basal segment full}^ as long as 

 the entire remainder, divided before the middle by a fine but dis- 

 tinct suture throughout the width, the suture anteriorly arcuate 

 in the middle ; remaining segments short and equal. Legs some- 

 what short and stout, the hind femora only slightly stouter, finely 

 subcarinate beneath; tarsi moderate, the basal joint normallj'- 

 elongate. 



Although this genus is one of the most distinct of the sub- 

 family, the species which compose it are closely allied and will 

 prove a difficult study ; the three which seem to be indicated by 

 the material in m}^ cabinet may be recognized as follows : — 



Elytral punctm-es distinct and well separated, not concealed or obscured by 

 the vestiture; elytra shorter and oval, the fuscous markings very much 

 confused and scarcely at all definable. 



Eyes larger, separated by their own width 1. ventricosiis 



Eyes separated by slightly more than their own width; head relatively 

 smaller and more convex 2. opiillUS 



Elytral punctures very dense and closely crowded, more or less obscured by 

 the vestiture, the elytra longer and more olilong, with four distinctly de- 

 fined irregular black spots at the middle of the disk; eyes separated by 

 much moie than their own width 3. palliatus 



Other species exist in collections, but I am not able to collate 

 them at present. The sexual characters appear to be extremely 

 slight.
