 L. G mill. 



Dull reddish brown or piccous, head distinctly darker, legs, 

 antennfB, and thorax concolorous ; the head is irregularly and 

 rather roughly punctured, with the median carina and the 

 suture, as noted in L. tripartitum^ scarcely visible, but between 

 the eyes there is a crescent-shaped elevation ; the thorax 

 more distinctly punctured than in the last species and less 

 narrowed behind, with the hind angles less obtuse, impressed 

 behind the neck ; the scutelluni slightly arched at the sides 

 and densely and distinctly sculptured ; the elytra margined 

 laterally, lateral interstice narrow and continuing to the base, 

 strife very feebly punctulate, interstices somewhat less flat 

 than in L. tripartitum.

Lyrosoma suturale, sp. n. 



Eufo-bruuneum, vix nitidum, sparse sed distincte punctatum ; 



elytris piceis, interstitiis intemis rufo-brunneis. 

 L. -ii mill. 



Reddish brown, somewhat shining ; the head uneven, with 

 two rather large shallow impressions on each side near the 

 insertion of the antennae, distinctly punctured in certain 

 places, most free from points on the disk ; the thorax punctured 

 and uneven like the head, hind angles slightly acute, less 

 distinctly narrowed behind than in L. Snoict, impressed behind 

 the neck ; thescutellum triangular, wholly sculptured, with a 

 few rather large punctures scattered over it ; the elytra are 

 piceous, except on the two sutural interstices, the striaj 

 distinctly punctate, especially in the scutellar area j the lateral 

 interstice is narrow and ceases before the apex.
