Head smooth, not grooved down the middle, chestnut-brown, with 

 some scattered short yellowish hairs; antennae smooth, cinnamon- 

 brown; first joint strongly punctured. Thorax straight in front, 

 the sides nearly parallel, the posterior angle somewhat projecting ; 

 the surface slightly scabrous, and rather closely covered with short 

 golden yellow hairs. Elytra with three prominent keels, the two 

 inner confluent beyond the middle of the elytra and continued in a 

 single keel, which is bent inwards near the tip ; the outer keel some- 

 what waved and slightly curved at the end ; in the space between it 

 and the other there is a shorter and less distinct keel, which about 

 the middle of the elytra passes into small tubercles ; the shoulders 

 and sides of the keels and the spaces between them at the base are 

 more or less covered with small tubercles ; the spaces between the 

 keels have many short golden yellow adpressed hairs. The spine at 

 the end of the suture is sharp, as is the outer margin of the elytra. 

 Legs compressed, brown.

Head short, slightly grooved between the eyes, under side of head 

 rough. Antennae with the first, second, third and fourth joints 

 thickly covered with small warts. Thorax with a spine on the lateral 

 edge about the middle, separated from the produced, somewhat re- 

 flected posterior angle by a rounded sinus ; surface covered with small 

 warts and outstanding inconspicuous hairs. Scutellum punctured, 

 with a raised line in the middle of the base. Elytra smooth, dark 

 brown, with a distinct costa running nearly to the tip, and another 

 between that and the suture, vanishing about the middle of the 

 suture ; elytra rounded at the tip, the suture with a short spine. 

 Legs with the femora and tibiae thick, the tarsi narrow. 



Cyrtonops, White, n. g. 



Head with largish eyes, which are hardly if at all emarginated. 

 Palpi long, with the terminal joint nearly twice the length of the pre- 

 ceding, obliquely truncated at the tip and covered on each side with 

 shortish hairs*. Antennae cylindrical, covered with small hairs, third 

 joint not much longer than the fourth. Thorax rather wider than 

 long, the sides angulated. Elytra with the sides nearly parallel. 

 Legs simple ; tibiae compressed, and more or less thickly covered with 

 short hairs. 



* In one of the specimens there is a curious malformation of the palpi ; from 

 the third joint proceed two longish hairy joints, one of them bent.
