rather finely sculptured and comparatively smooth. The 

 description is taken from fourteen examples (three of which 

 belong to the Oxford Museum), including a pair still " in 

 copula." A larger female, also found by Truqui, with 

 a broader, narrowly fusco-vittate prothorax may belong 

 here. The fine cinereous pubescence of the elytra gives 

 a greyish appearance to the surface.

Silis hilara, Gorh., Biol. Centr.-Am., Coleopt. iii, 2, p. 306 

 (part.) ((^ and $ with legs in part red). 



Hab. Mexico, Cordova. 



The types of Silis hilara, ^ $, are very like D. (Silis) 

 coarctatum ; but the male has broader and more thickened 

 lateral prominences, and acute hind angles, to the pro- 

 thorax, and smaller eyes than in the corresponding sex of 

 that species ; the femora to near the apex, and the basal 

 half or more of the tibiae, are testaceous ; and the elytral 

 punctuation is as coarse and distinct as in D. pavxillum, 

 the cinereous pubescence, too, being long and conspicuous. 

 The black-legged specimen ($) placed by Gorha-m under the 

 same species is here referred to D. coarcfafimi. The three 

 tarsi have one of their claws cleft at the tip in the male.

Silis pauxilla (incl. vars.), Gorh., Biol. Centr.-Am., Coleopt, 

 iii, 2, pp. 304, 305 (excl. Zunil specimens). 



Hab. Guatemala, Cubilguitz, Senahu, and San Juan 

 in Alta Vera Paz ; Panama, Volcan de Chiriqui. 



The types of Silis pauxilla, Gorham, were from Chiriqui, 

 and the Guatemalan examples [excluding those from Cerro 

 Zunil, which are females with bent mandibles and are here 

 treated as a var. of his Silis oblita] evidently belong to the 

 same species. One of the varieties, that with the basal 

 half of the femora testaceous, represented by two females, 

 is from Vera Paz ; the other, with the head (the base or a 

 spot on the vertex excepted), the basal half or more of the 

 antennae, and the legs in great part (the outer half of the 

 posterior femora excepted), testaceous, is represented by 

 numerous females from Chiriqui. The type is shining, 

 black, with the front of the head, the base of the antennae 

 beneath, and the prothorax (except along the anterior
