 elliptical area adjoining the front ; eyes variable in size but 

 generally large ; the gula with one or more transverse grooves or 

 depressions in front. Antenna shorter than the body in the $ , 

 usunlly longer than the body in the tf , but never twice as long ; 

 third to fifth joints more or less strongly thickened at the apex, 

 fifth to tenth angulate in front and never spined posteriorly at the 

 apex. Prothorax more or less transverse, rounded at the sides. 

 Elytra moderately long, truncate or rounded at the apex. Legs 

 rather long, the femora subliriear, not carinate ; the hind pair 

 reaching to the apex of the elytra in the 6" , or nearly so. First 

 joint of the hind tarsus not longer than the next two united. 

 Acetabula of front coxae rounded, or sometimes very narrowly

Dark chestnut-brown, not very densely covered with a short 

 silky, somewhat golden-yellow pubescence, and so. arranged on

 Head marked above with a short 

 median groove which extends from 

 between the eyes to a little distance 

 beyond them posteriorly ; antennal 

 supports separated by a narrow 

 groove-like interval ; eyes rather large, 

 the genae somewhat short. Antennae 

 slightly shorter than the body in 

 the $ , exceeding it by from one-third 

 to nearly half of their length in the 

 <3 ; third to fifth joints sutinodose at 

 the apex; third and fifth subequal, 

 each about one-third longer than the 

 first or fourth. Prothorax slightly 

 protuberant at the middle of each 

 side, narrowed towards base and apex, 

 transversely and not very strongly 

 rugose above, with the ridges more or 

 less sinuate and irregular ; its length 

 about equal to its width across the 

 middle. Elytra long, narrowed gradually and very slightly from 

 the base for about four-fifths of 'their length and then more 

 strongly ; each trnncate at the apex and armed with a short 

 sutural spine. Femora nearly parallel -sided, the hind pair not 

 reaching to the apex of the elytra in the J First joint of the 

 hind tarsi about equal in length to the second and third united.

 tuberculate posteriori v.
