LEPTOSTYLA. 15 
testaceous, the tarsi slightly infuscate; the pronotum with the margins and the summit of the dorsal 
appendages, and the elytra with the costal margin to near the apex and the nervures, set with short fine 
sete. Head with three long spines—one frontal and two lateral; antenne indistinctly pilose, long 
and slender, joint 1 three times as long as 2, 2 very short. Pronotum with the membranous margins 
broad, recurved, and rounded, with three rows of areole; hood very large, oval, widely reticulated ; 
the median carina strongly foliaceous and equally raised, with two rows of areole at the middle, the 
outer carine long and moderately foliaceous; the triangular posterior portion membranous. LElytra 
long, widening from the base, the costal margin hollowed in the middle, the apex rounded; discoidal 
area slightly raised, somewhat fusiform, rather short, not very closely reticulated; subcostal area 
narrow, subvertical, uniseriate; costal area with two rows of areole at the base and three at the 
middle ; the areole in the apical half of the sutural area very unequal in size, three of them being large 
and pentagonal. 
Length 33, breadth 13 millim. 
Hab. Panama, Bugaba (Champion). 
One specimen. Not unlike L. gracilenta; but differing from it in the setose margins 
of the pronotum and elytra, the pronotum with the hood very much larger, the median 
carina strongly foliaceous, and the membranous margins broadly, arcuately dilated and 
triseriate, the elytra with the discoidal area less closely reticulated and the costal 
margin more sinuous. 
5. Leptostyla fimbriata, n. sp. (Tab. I. figg. 19; 19a, profile.) 
Elongate, narrow ; body black, the integument white and hyaline, the elytra with the nervures in the apical 
half, and also the transverse ones along the costal margin thence to near the base, and a small spot on 
the median carina of the pronotum, fuscous; the antenne fuscous, with the basal and apical joints 
black ; the legs testaceous, the tarsi black; the pronotum with the margins, hood, and the three carinz 
in front, and the elytra with the costal margin to beyond the middle and the nervures, set with long, 
fine, projecting hairs, those on the elytra arising from very minute denticules. Head with five slender 
spines; antenna pilose, slender, elongate, joint 1 three and a half times as long as 2, 2 very short, 4 
much longer than 1. Pronotum with the membranous margins moderately broad, recurved, converging 
in front, with two rows of areole; hood rather short, broad-oval, considerably raised; the long median 
earina strongly foliaceous, becoming lower in front, with a single row of large transverse areolew, the 
outer carine moderately foliaceous; the posterior triangular portion membranous, Elytra long, 
widening from the base, rounded at the tip; discoidal area extending very little beyond the basal third, 
rather widely reticulated ; subcostal area narrow, biseriate; costal area with two rows of areole at the 
middle and one at the base, the areole large, those at the base strongly transverse; the areole in the 
apical half of the sutural area very unequal in size, two of the inner ones being very large and pentagonal. 
Length 33, breadth 13 millim. 
Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith). 
One specimen. The chief characters of this species are the pilose margins of the 
pronotum and elytra, the large areole of the costal area of the elytra, uniseriate at 
the base and biseriate at the middle, and the moderately wide biseriate membranous 
margins of the pronotum. 
6. Leptostyla fuscofasciata, n. sp. (Tab. I. figg. 20; 20 a, profile.) 
Moderately elongate, narrow ; body black, the integument whitish and hyaline; the elytra with an oblique 
fascia towards the apex, the nervures thence to the tip, and three transverse ones radiating from the 
costal margin before the middle, fuscous, the others pale testaceous, the apical areole also partly clouded
