COLASPIS. 141 



interstices very obsoletely costate near the apical and lateral margins ; underside and legs fulvous, the 

 base of the tibiae piceous ; legs rather short and robust. 



Hab. Bkitish Honduras, river Sarstoon (Blancaneaux) ; Guatemala, Yzabal (SallS), 

 La Tinta, Chacoj (Champion) ; Panama. 



The more than usually long thorax, its fine punctuation, and that of the elytra, 

 together with the peculiar light metallic green colour, distinguish this species well 

 from its allies. In the specimen from Panama in my collection the breast is also 

 tinged with metallic green. The figure is drawn from the Mexican form. 



12. Colaspis fulvo-testacea. 



Colaspis fulvo-testacea, Lefev. Mitth. Munch, ent. Verein. 1878, p. 123 \ 

 Hab. Mexico, Tuxtla (Salle) ; Guatemala, Zapote (Champion).— Colombia 1 . 



A single male specimen from Mexico and a female from Guatemala which are 

 before me do not seem to differ from M. Lefevre's description of his species in any 

 respect ; and as several instances of species of Colaspis being common to Colombia and 

 Mexico have occurred, I see no reason to separate the species. The difference in size 

 of the sexes before me is very great, the female being considerably larger, and of nearly 

 double the width of the male. 



13. Colaspis belti. (Tab. VI. fig. 21.) 



Oblong-ovate, piceous below, above fulvous ; sides of thorax bidentate, middle of disk piceous ; elytra closely 

 punctate-striate, with an indistinct transverse piceous basal band ; knees and base of tibiae black. 



Var. a. Thorax without dark spot. 



Var. b. Entirely light fulvous. 



Length 2^-3 lines. 



Base of the head very swollen, impunctate, flavous, with a deep transverse groove between the eyes ; clypeus 

 very strongly punctured; jaws black; antennae slender, entirely flavous ; thorax transversely convex, its 

 sides greatly widened at the middle and produced into two distinct teeth, the basal angles also acutely 

 dentate, surface of the disk closely and distinctly punctured, the sides a little less closely; an obscure 

 ill-defined patch is situated in the centre of the base, but does not extend to the apex; scutellum fulvous; 

 elytra deeply transversely depressed below the base, strongly and very closely punctate-striate, the punc- 

 tuation getting more distinct and weaker towards the apex, where the interstices are slightly raised ; the 

 colour is the same as that of the thorax, but is interrupted below the base by a broad, more or less 

 distinct, piceous. band, which is common to both elytra, and extends to the lateral margin; underside 

 piceous,' last abdominal segments fulvous ; legs of the same colour, the knees and base of the tibiae 

 black. 



Hab. Nicaragua, Chontales (Belt, Janson). 



The description is drawn from a well-marked specimen ; in another the dark marking 

 of the thorax is wanting, and that of the elytra much less strongly defined, while the 

 variety is entirely devoid of dark spots; but in all specimens the coxa; and knees are 

 black. The male has, as usual, the anterior tarsal joint dilated. Three specimens were 

 obtained by Belt, and one by Janson.
