elytra more conspicuous, and along the base of the first are 

 some aciculate punctures, the prosternal keel is shorter and 

 the lateral striae diverge less posteriorly. The forehead also 

 is less prominent over the eyes.

Trihalus tropicus. Lew. 



Tribalus tropicus, Lew. Ann. & Mag. Nat. Hist, ser. 5, xvi. p. 212 



(1885). 



Herr J. Schmidt has stated (Ann. Mus. Civ. Geneva, 

 ser. 2, xvii. (xxxvii.) p. 294, 1897) that the above species is 

 T. DoricB, Mars. T. Dorice is opaque and depressed, and 

 the dorsal punctuation is obscure. T. tro-picus is convex, 

 ■with ocellate punctures, and resembles T. koenigius, Mars. 

 I found T. Dorice at the same time as T. tropicus, and I may 

 have sent Herr Schmidt a specimen of the fir.st instead of the 

 second ; but there is no near resemblance between the two 

 species.

 feebly bisinuous in front; the thorax with a lateral band of 

 coarse punctures, with rugose oblique interstices in the middle

 lique at base and extending beyond the middle, 4-5 basal and 

 curved, sutural apical, fine, and reaching beyond the middle, 

 the elytra posteriorly and the pygidia are rather finely and

 anteriorly and widens out a little to the base, the lateral strige 

 follow the outline of the keel and terminate just before the
