CORYNOMALUS. 117 



it appears to be rarer further north. We have not received it from Guatemala ; it 

 is, however, recorded from there by Gerstacker. In a variety from Venezuela the 

 elytra are reticulated, having a longitudinal striga in addition to two fasciae, the striga 

 dividing the black of the disc into seven or more spots. 



We figure a specimen of the type-form (fig. 2), and a male example of var. b of 

 Gerstacker (fig. 3), both from Caldera in Chiriqui. 



5. Corynomalus saturate. (Tab. VII. fig. 4.) 



Piceus, prothoracis disco elytrisque saturatius nigro-pieeis ; antennis dilutius rufo-piceis, clava nigra ; elytris 

 disperse profunde punctatis ; prothorace f ortiter transverse Long. 7 millim. 



Hab. Panama, Bugaba, Volcan de Chiriqui 2500 to 3000 feet, David [Champion). 



This species is allied to C. interruptus and C. cinctus, but is smaller than average 

 examples of either, and darker ; the thorax is very short, and more than twice as wide 

 as long ; and the elytra are very deeply and sparsely impressed with large punctures 

 which increase in size towards the margins. In one example the thorax and elytra are 

 of a uniform pitchy -black, while in two others the suture and margins are pitchy-red. 

 The interstices between the large punctures of the elytra are nearly smooth and are 

 shining, but under a quarter-inch lens numerous minute punctures are visible. The 

 underside is of the same pitchy colour as the thorax, and is shining and smooth, but 

 with minute punctures. 



Four specimens. 



6. Corynomalus castaueicolor. 



Castaneus vel ferrugineus, antennis, palpis pedibusque nigris, prothorace brevi transverso, elytris disperse 



punctatis. Long. 7|-8 millim. c? 2 • 

 Mas tibiis intermediis apice interne exciso et incurvato. 



Hab. Nicaragua, Chontales (Janson, Belt). 



Very like the South-American C. Icevigatus, Gerst., and formerly referred by me to 

 that species ; but the Nicaraguan insect differs from it in the following particulars : — It 

 is broader, with the margins a little more expanded ; the thorax is wider, especially at 

 the base ; and the elytra are distinctly punctured. The coxae, trochanters, and the 

 extreme base of the thighs are yellow. A very considerable number of specimens of 

 this species were collected by the late Mr. E. Janson at Chontales, and I have seen a 

 few captured by Mr. Belt.
