Convex, ochraceous : head and thorax glossy, very minutely or hardly punc- 

 tured : scutel colored like the thorax, very minutely punctured; elytra darker 

 than the thorax, distinctly punctate-striate, the second, fourth, sixth and eighth 

 interstices, each with a series of distant large punctures : antennas palpi, feet 

 and venter testaceous : posterior tibiae ( $ ) greatly bowed. 



2. L. discolor. Piceous above, rufo-testaceous" beneath. — I J 1. long. Penn-
