pubescent. The outer spur of the hind tibie is broader and stouter than the inner 
one. The male has the joints 3-6 of the antenne flattened and considerably dilated, 
and a single spur to the anterior tibia. There can be little doubt that the insects 
described by Haag! and Dugés? belong to one and the same species, notwithstanding 
certain discrepancies in the description: Dugés omits to mention the basal spots of the 
elytra, and Haag the fulvous apex. It is probable that they only had discoloured or 
worn specimens before them. A male from Iguala is figured.

This is the commonest species of the genus in Mexico, and we have received hundreds 
of specimens of it. Two forms occur:—one with the apices of the elytra, and some- 
times the humeri and sides also, luteous, and the suture, lateral margin, and a median 
line on the disc clothed with lighter pubescence than the rest of the surface (E. rujfipedes, 
Dug., = subvittata, Haag); the other with an elongate-triangular scutellum patch, 
and the suture, apex, and lateral margin of the elytra, to a variable extent, luteous or 
ferruginous, and the median line of lighter pubescence partially or entirely obsolete 
(£. cinctella, Dug.). The Yucatan and Guatemalan specimens are intermediate, and 
might equally well be placed with either. Both forms were found in plenty at Oaxaca. 
In many undoubted examples of HL. rufipedes the median line of lighter pubescence is 
more or less evanescent, or even obsolete, so that but little value can be placed on it as 
a specific character. In the male of this species the third and following joints of the 
antenne are flattened and strongly compressed—3 elongate-triangular, three times as 
long as, and twice the width of, 2, 4-10 subequal in length, but diminishing in width, 
4 and 5 as wide as, but much shorter than, 3; the anterior tibie with a single spur. 
The legs are reddish-testaceous, with the tarsi infuscate or black. The antenne are
