ELYTROLEPTUS (to follow the genus Pteroplatus, p. 73). 
Pteroplatus, Thomson, Leconte. 
Elytroleptus, Dugés, La Naturaleza, iv. p. 184. 
Distinguished from Pteroplatus, which the species much resemble, by their short 
antenne (in the female of the typical species only about one third, in the male more 
than one half, the length of the body), and by their joints 5-11 being triangular and 
produced at their inner apices, none of them being penicillated, even in the male. The 
species described by Dugés are more linear in form than the Pteroplati; but this is 
not a constant difference, other species having dilated elytra, and the facies of Lycus 
similar to the Pteroplati. The genus seems to be peculiar to Mexico and the southern 
United States; Pteroplatus floridanus, Leconte, belongs to it. 
1. Elytroleptus octocostatus (Pteroplatus octocostatus, p. 73). 
This species has serrated antenne, with the four basal joints clothed only with short 
hairs; it belongs, therefore, to Elytroleptus rather than to Pteroplatus, but it is peculiar 
in the strong dilatation and fringed margins of the elytra and in the form of the 
thorax.
