Trihalus tropicus, Lew. Ann. & Mag. Nat. Hist. ser. 5, ivi. p. 212 



(1885). 



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

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

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

 the dor.sal punctuation is obscure. T. tropicus is convex, 

 with ocellate punctures, and resembles T. kosnigi'us, Mars.

 have sent Herr Schmidt a specimen of the i\T?.t instead of the 

 second ; but there is no near resemblance between the two 

 species.
