The peculiarity of the anterior tibiae is apparently gene- 

 ric, or at least affects a large number of species. 



L. versicolor u. sp. — Very slender; sides parallel; colors and pubescence 

 as in hicolor, except that the abdomen is dark fuscous and slightly paler at 

 apex. Head rather large; distinctly longer than wide; sides behind the eyes 

 feebly but distinctly divergent and feebly arcuate to the base which is broadly 

 and distinctly sinuate; angles rather prominent and narrowly rounded; front 

 broadly and feebly convex, not reticulate, shining, very minutely, evenly and 

 rather densely punctate; punctures separated by two or three times their 

 own diameter; antennae one-half longer than the head, second joint much 

 longer and more robust than the third, fifth very slightly longer than wide, 

 tenth very slightly wider than long. Prothorax widest at one-fourth its 

 length from the apex, distinctly narrower than the head; anterior angles 

 narrowly rounded, prominent; sides thence strongly convergent and distinctly 

 sinuate to the neck which is very slender, and distinctly convergent and 

 nearly straight to the base which is transversely truncate and three-fourths 

 as wide as the disk; angles somewhat narrowly rounded; disk one-third 

 longer than wide, feebly convex, very minutely, evenly punctate, scarcely 

 visibly subrugulose; punctures scarcely perceptibly more sparsely distributed 

 than those of the head; median stria toward base nearly obliterated. Elytra 

 at base scarcely perceptibly wider than the prothorax; sides distinctly diverg- 

 ent and very feebly arcuate; disk very feebly convex, very feebly impressed 

 along the suture toward base, minutely and feebly subrugulose, finely, 

 evenly, rather densely and subasperately punctate; slightly longer than 

 wide and just visibly longer than the pronotum. Abdomen nearly as in 

 hicolor, slightly more sparsely punctate. Length 2.1-2.5 mm. 



Texas; (Austin and Waco). 



The sixth segment in the male is broadly sinuate at apex, 

 the sinus being slightly less than four times as wide as 

 deep, rather acutely rounded; ligula long and narrow, per- 

 fectly flat, gradually wider toward the apex which is broadly 

 and extremely feebly sinuate, angles rounded. 



The anterior femora and tibiae are as in hicolor, but the 

 former are not so robust as in that species. The form of 

 the head and the sexual characters will serve to distinguish 

 this species from the preceding, to which it is otherwise 

 closely allied. 



L. longiceps u. sp.— Very slender, rather convex; 'sides parallel; head 

 and elytra pale brownish-testaceous; prothorax paler, more flavate; abdomen 

 dark fuscous, scarcely paler at apex; autennee and legs tbroughont pale rufo-
