136 LEPTOTKICHUS. 



anterior angles and the sides ; more convex than in the preceding 

 genus ; in form transverse, slightly compressed in front, comparatively 

 much broader than in the next genus. 



Scutellum broadly triangular, pubescent. 



Elytra robust, short, subcylindrical, much more robust and broader 

 than the thorax ; more convex than in the preceding genus. 



Legs : anterior femora short, robust, slightly dilated medially. The 

 tibia; are short, inflected abruptly at their immediate base, somewhat 

 thickened towards the apex. The tarsi are sufficiently broad ; the 

 two basal joints subelongate and triangular (the second being smaller 

 than the first) ; the third is transversely subcircular, deeply bilobed, 

 and margined with a deep, dense fringe of rigid pubescence ; the 

 apical joint is attenuate and gradually thickened, as well as in- 

 flected towards the apex : the terminal claw is bifid, and armed at 

 the inner surface with an obsolete basal tooth. The posterior femora 

 are, when viewed transversely, broadly incrassated, short, rounded 

 at the upper surface, extending nearly to the apex of the elytra. The 

 tilia; are short, robust, inflected at the immediate base, slightly 

 attenuated medially ; at the apex broadly obliquely truncate, and at 

 the angle of truncation slightly dilated ; the socket which receives 

 the base of the tarsus is simple (not armed with comb-like teeth), 

 and produced apically into a single well-developed spur. The tarsus 

 is inserted at some little distance from the apex of the tibia, short, 

 and much narrower than those of the anterior feet ; the first and 

 second joints are triangular in form and elongate ; the third not 

 broader, subcircular, and almost bilobed ; the last joint is attenuated, 

 and produced apically into a broadly inflated globular projection, 

 which completely conceals from above the terminal claw. 



This genus may be distinguished from all allied to it, by its 

 distinctly elongated maxillary palpi, and also by its robust body and 

 dilated antennae from the preceding genus. 



1. Leptotrichus castaneus. (Tab. V. fig. 4.) 



L. ovatus, robustus, latus, castaneus, flavo-pubescens ; capite anticc 

 foveolato; thorace transverso,punctato, ad laterafavo-pubescenti; 

 scutello pubescenti ; elytris robust is, punctatis, ad apicem latera- 

 que pubescentibus ; antennis validis, fortiter incrassatis, art. 1-5 

 jiavis, 6-11 nigris ; pedibus Jiavis. 



Long. corp. 2i lin., lat. 1| lin. 



Ovate, short, robust, castancous, flavo-pubescent. Head short, 

 not produced ; below the base of the antennao is a transverse trian- 

 gular depression ; above the base, between the eyes, is an obsolete 

 T-shaped fovea (forming within it two slight elevations); surface
