36. Doryphora uniformis. 



Below, the antennae and the scutellum black ; above rufous ; thorax very finely punctured ; elytra geminate 

 punctate-striate at the sutural half. 



Length 4| lines. 



Head very minutely and rather closely punctured; labrum obscure piceous; apex of jaws black; antennae 

 extending to the first third of the elytra, black, the basal joint rufous below, the first seven joints shining, 

 the rest, with the exception of the terminal joint, short, transverse, subquadrate ; thorax about twice as 

 broad as long, widened at the middle, the sides nearly straight and parallel, surface scarcely visibly punc- 

 tured at the disk, a little more distinctly at the sides ; scutellum broad, subovate, shining black ; elytra 

 slightly wider at the base than the thorax, rufous, like the head and thorax, finely geminate punctate- 

 striate near the suture, the sides irregularly punctured ; underside and legs black, with a slight greenish 

 tint ; mesosternal process very short. 



Hab. Panama, Volcan de Chiriqui {Champion). 



The single specimen obtained bears a close resemblance to Leptinotarsa rubiginosa 

 in regard to colour. The structure of the mesosternum will of course at once 

 distinguish it. 



37. Doryphora arangoi. 



Doryphora arangoi, Steinheil, Mittheil. ent. Ver. Miinchen, 1877, p. 43, tab. i. fig. 6 \ 

 Hab. Guatemala, Las Mercedes, Cerro Zunil (Champion). — Colombia 1 . 



The dozen specimens obtained by Mr. Champion agree so closely with the figure 

 given by Steinheil, and also for the greater part with his description, that I cannot 

 but refer them to this species. The only differences that I find are, the finely 

 punctured interstices of the elytral striae, of which Steinheil makes no mention, and the 

 shape of the sutural dark band, which in the Guatemalan insects is extremely narrow. 

 The elytral second transverse band is either free as the author described it, or connected 

 by a thin point with the suture. 



38. Doryphora flavoguttata. (Tab. XIV. fig. 2.) 



Doryphora flavoguttata, Jacoby, P. Z. S. 1878, p. 145 \ 



Hab. Costa Rica, Volcan de Irazu \ Rio Sucio (Rogers). 



But three specimens of this species have been received, the spots on the elytra of 

 which are not flavous (as the name would indicate), but dark fulvous. 



39. Doryphora bisbimaculata. (Tab. XIV. fig. 8.) 



Doryphora bisbimaculata, Jacoby, P. Z. S. 1877, p. 518 \ 

 Hab. Nicaeagua, Chontales (Janson l ). 



In addition to the light fulvous patches of the elytra as represented in the figure, 

 there is often another minute spot of the same colour visible near the apex. I have 

 seen only four specimens from Nicaragua.
