Leiopleura, Deyrolle, Ann. Soc. Ent. Belg. viii. p. 219 (1864) . 



The six described species of this genus are from Cuba and South America ; twenty- 

 three are here recorded from Central America." 



1. Leiopleura intermedia. (Tab. IX. fig. l.) 



Oblonga, depressa, subtus nigra, supra cuprea ; capite antice viridi, subtiliter punctulato ; tborace medio paullo 

 infuscato, nitido, parce punctato, lateribus confertim subtiliter rugosis et parce punctatis, marginibus 

 viridibus ; elytris confertim subtiliter rugosis, parallelis, ad apicem arcuatim attenuatis, regione suturali 

 paullo infuscata, magis nitida, parcius punctata. 



Long. 1| lin. 



Hah. Guatemala, Cerro Zunil 4500 feet (Champion). 



The antennae when at rest are lodged in an impression on the under flank of the 

 prothorax. The front legs are also lodged in a well-marked impression ; the anterior 

 and intermediate tibiae are subcylindrical ; the posterior tibiae are a little widened at the 

 middle. The head has a slight longitudinal impression in front ; it is densely and finely 

 rugose and punctured. The thorax is widest just before the base, convex, without any 

 lateral impression. The elytra are a trifle narrower than the thorax, subparallel for 

 two-thirds their length, and then narrowed to the apex ; there is a light impression 

 at the side below the shoulder and another near the suture before the apex. 



2. Leiopleura contigua. (Tab. IX. fig. 2.) 



Oblongo-ovata, sat lata, depressa, nigra, nitida ; capite virescente, confertim subtiliter rugoso, parce punctato, 

 antice leviter coneavo; tborace subtilissime rugoso, punctato, disco fusco-nigro, lateribus virescentibus, 

 leviter impressis ; elytris nigro-purpurascentibus, crebre subtiliter punctatis. 



Var. Capite tboracisque lateribus concoloribus.

Hab. Panama, Volcan de Chiriqui 3500 feet (Champion). 



The thoracic impression for the antennas is very short and shallow. The anterior 

 legs are in repose lodged in a cavity in the prothorax ; the tibiae of the front legs are 

 subcylindrical, a little thickened near the base; the intermediate tibiae are much 

 curved ; the posterior tibiae are very slightly flattened, but not dilated. The antennae 

 and the anterior surface of the femora and part of the tibiae are green. The thorax 

 has the disc marked with stelliform punctures, which are not very close together. The 

 elytra have the margin below the shoulder flattened ; there is a light impression on the 

 margin behind the middle, and another nearer the suture not far from the apex. 



A second specimen differs from the one above described in the green colour being 

 absent.
