186 PHTTOPHAGA. 



thirty species being enumerated in Gemminger's and v. Harold's Catalogue, the species 

 from the New World amounting to seven only at the time of publication ; since then, 

 however, many more have been described by M. Lefevre from South, and two other 

 species by myself from Central America. Mexico has not, up till now, furnished us 

 with any species, no example being contained either in M. Salle's or Herr Hoge's 

 collections ; so that Guatemala seems to be the most northern limit of the genus. The 

 latter may be known by its ovate, convex, and rather short shape, and the convex 

 anterior thoracic episternum. M. Baly has remarked that the species from the Old 

 World have generally punctate-striate, those from the New World more irregularly- 

 punctured elytra, which I have also found to be generally the case.

The two specimens in my collection which I received from M. Boucard are of a 

 bright metallic green colour, and of nearly the same shape and size as C. wiicolor. The 

 head and thorax are very finely and rather irregularly punctured, the interstices having 

 a somewhat rugose appearance ; the elytra are also much more closely and finely 

 punctured than in C. unicolor. 



2. Colaspoides chiriquensis. 



Ovate convex, metallic green below ; antennse testaceous, the terminal joint piceous ; tibiae and tarsi fulvous ; 

 above obscure metallic cupreous ; bead and thorax finely, elytra closely and more strongly punctured. 



Length 2f lines. 



Head rather flat, closely and finely punctured at the vertex ; clypeus distinctly separated from the lace, its 

 apex concave-emarginate, its surface more strongly punctured than the head, and of a more aureous colour, 

 the margins metallic green ; labrum and jaws dark fulvous ; maxillary palpi and the antennse testaceous, 

 the latter slender, filiform, and extending beyond the half of the elytra, their two apical joints obscure 

 piceous; thorax nearly three times as broad as long, very convex, and of almost equal width, the sides 

 evenly rounded and distinctly narrowed anteriorly, surface very finely and closely punctured ; seutellum 

 about as broad as long, finely punctured; elytra about one half longer than broad, slightly narrowed 

 towards the apex, with a very obsolete depression below the base, very closely, evenly, and more strongly 

 punctured than the thorax, of a dark cupreous colour; the suture towards the apex metallic green; 

 prosternum a little broader than long, its base slightly concave, surface somewhat rugose ; thighs 

 unarmed.
