1. Tetralohus Chevrolatiij Cand. Elat. i. p. 374. 



In my specimen I observe one character not noticed by 

 Cand^ze in his description, viz. that the spine of the pro- 

 sternum is deeply canaliculate. 



One specimen.

 fronte punctata, postice linea l^vi carinata, antice excavato,

Long. 19 lin., lat. 6 lin. 



Brownish black, clothed with an excessively short but dense 

 silky fulvous down, thickly punctured, elongate, rather narrow, 

 transversely convex, so as to appear almost subcylindric, at 

 least as regards the elytra. Head rather coarsely punctate, 

 behind with a slight smooth raised line, in front with a deep 

 longitudinal excavation ; the frontal transverse keel subrotun- 

 date, in some aspects like a truncate triangle with the corners 

 rounded and the middle slightly sinuate. The prothorax 

 closely and rather coarsely punctate, unequal on its surface, 

 slightly depressed on each side of the middle in front, also on 

 the disk, and on each side behind the middle, and with a small 

 oblique distinct fovea near the posterior angles ,* the sides 

 parallel, margins rounded in, anterior angles rounded, posterior 

 strongly divaricate, with their apex sHghtly incurved, and with 

 a small raised tubercle in their middle ; base with a lobe in front
