Stenotarsus is the largest genus in the Endomychidse, the described species amounting 

 to about seventy. They are generally distributed in the Tropics. The American repre- 

 sentatives can usually be distinguished from those of Africa and the East by not having 

 the punctures on the elytra arranged in striae. Its species are more thickly pubescent 

 than most of the family ; they are usually of a rich brown or rusty-red colour, often 

 clouded with black, but seldom spotted, and are only of medium or small size. 



According to Mr. Champion, they are of similar habits to Anidrytus and Epopterus. 



Section A. Antennae with the third to the seventh joints longer than broad. 



1. Stenotarsus cordatus. (Tab. VIII. fig. 4.) 



Breviter ovatus, convexus, saturate rufo-ferrugineus ; pectore abdominisque segmento primo, prothoracis disco, 

 elytrorumque plagia discoidali indeterminata in singulis piceis; antennis basi rufis, articulis quatuor 

 ultimis nigris. Long. 7 millim. 



Sab. Guatemala, Teleman and Senahu in Vera Paz (Champion). 



The form of this species is broadly ovate ; the elytra are cordate, less convex than in 

 S. coccineus. The head and thorax are very minutely punctured. The thorax has the 

 disc shining and almost glabrous, the margin flat, wide, and scarcely narrowed behind ; 

 the sides are very much narrowed to the front angles from the hind angles, which are 

 acute, and are also gently and evenly rounded. The elytra have the usual unequal 

 puncturing, the larger irregular punctures being numerous on the sides and towards 

 the apex ; their margins are finely reflexed. The antenna? are rather long and thin, 

 with a lax club, the first seven joints clear red ; in the example from Teleman the 

 third, fourth, and fifth joints are very little longer than wide, but in the one from 

 Senahu these joints are much longer. The specimen from Senahu also has the legs 

 longer, and the hinder pair of tibiae a little bent ; I have, therefore, doubts whether 

 this is the male sex or a distinct species. 



The length of the legs is a good specific character : I do not known any other species 

 with them so formed. The male (?) from Senahu will be the type for this species. 



2. Stenotarsus orbicularis. 



Stenotarsus orbicularis, Gerst. Monogr. Endom. p. 322 x ; Gorh. Endom. Recit. p. 25 2 . 



Hab. Guatemala 1 2 , Teleman and Panzos in Vera Paz (Champion) ; Panama, Volcan 

 de Chiriqui below 4000 feet (Champion). 



The specimens which I assign to this species agree fairly well with Gerstacker's 

 description, and are distinct from any other known to me ; I have not, however, ever 

 seen an authenticated example of 8. orbicularis. I will, therefore, give the characters
