is on the outside of the lateral keel, except near the hind border of the pro- 

 notum, where it appears also on the inner side. Tip of the vertex flat, con- 

 ical, with slight elevated border ; furrow on each side nearly obsolete ; front 

 (face) punctured, very oblique, the four keels diverging toward the face, the

 form a ridge. Antennae slender, nearly cyhndrical, rather longer than the 

 head and the pronotum together. Pronotum with three very slight keels ; 

 lateral keels slightly converging from the fore border to the first transverse 

 furrow, where they are slightly angular, and whence they diverge slightly to 

 the hind border, which is rounded ; the two transverse furrows approach 

 each other on the disk. Abdomen somewhat shorter than the hind femora. 

 Hind femora with an irregular and interrupted blackish stripe on the outer 

 side, with an entire blackish stripe beneath, and with a blackish spot on the 

 disk of the inner side; hind tibias and hind tarsi whitish, the former with an
