furthest at the base. The length of the first joint of the antenne is about equal to that 
of the head, which is shorter than the pronotum. 
This genus is found in the Neotropical, Nearctic, Ethiopian, Oriental, and Australian 
Regions. The great majority of the species are Neotropical, about one third of the 
whole number being found in Central America, to which subregion a few are peculiar.

The colour of the upper surface of the abdomen in this species is concolorous, a 
character which appears to distinguish it from L. fulvicornis, Hope. It also appears to 
have a considerable affinity to L. corculus, Say; but Walker describes the rostrum of 
L. concolor as extending only to the second ventral segment, whilst Mayr in his 
description of Theognis excellens, which is accepted by both Stal and Uhler as a 
synonym of Say’s species, states that the rostrum is “ad abdominis segmenti 4 basin 
extensum.”
