LEPTOSTYLA. 17 
8. Leptostyla lineata, n. sp. (Tab. I. figg. 22; 22a, profile.) 
Moderately elongate, rather broad; body black, the integument whitish and hyaline; the elytra with a 
narrow, oblique, smoky-black fascia extending from the median nervure a little beyond the middle to the 
apex, the nervures within the discoidal area and those between it and the suture fuscous, the others 
flavous ; the antennz with joint 3 testaceous, the other joints brownish-black ; the legs testaceous, with 
the apical joint of the tarsi black. Head with three long slender spines—one median and two lateral; 
antenne long and slender, joint 1 three times as long as 2 and slightly shorter than 4, 2 very short, 
4 distinctly pilose. Pronotum with the membranous margins moderately wide, rounded, converging 
from the middle forwards, recurved, with two rows of small areole; hood short, compressed, strongly 
raised, angularly projecting in front; the three carinw feebly foliaceous, the median carina continuous in 
front with the hood and becoming more strongly foliaceous behind, the interspaces sparsely punctured. 
Elytra moderately long, gradually widened from the base, the costal margin hollowed at the middle, 
the apex narrowly rounded, the apical margin oblique; discoidal area nearly reaching the middle, sub- 
fusiform, closely reticulated; subcostal area narrow, biseriate ; costal area with two rows of areole, 
the areole large and few in number, becoming much smaller at the base; sutural area also with large 
areole, except in the basal half, which is closely reticulated. 
Length 3, breadth 14 millim. 
Hab. Guatemata, San Isidro (Champion). 
One example. Lasily distinguishable by the narrow, straight, oblique, smoky-black 
fascia of the elytra, and the large areole of the costal and sutural areas, those of the 
subcostal and discoidal areas being small and rounded. 
9. Leptostyla gracilenta, n. sp. (Tab. I. figg. 23; 23 a, profile.) 
Moderately elongate, narrow ; body black, the integument whitish and hyaline; the elytra with part of the 
discoidal area, an oblique fascia beyond it, extending from the middle of the inner margin to the costal 
margin near the tip, and the nervures thence to the apex, fuscous; the antenne testaceous, with the 
basal and apical joints black; the legs testaceous, the tarsi slightly darker. Head with five long 
slender spines ; antenne long and slender, the basal joint three times as long as the second, the latter 
short, joint 4 longer than 1. Pronotum with the membranous margins moderately wide and recurved, 
slightly converging forwards, with two rows of areole; hood moderately large, strongly raised, broad- 
oval, with but few areole; the three carine feebly foliaceous, the median carina more raised than the 
others, the interspaces punctured ; the triangular posterior portion membranous and reticulate. Elytra 
long and rather narrow, slightly hollowed at the middle of the costal margin, broadly rounded at the 
tip; discoidal area somewhat fusiform, not half the length of the elytra, closely reticulated ; subcostal 
area narrow, biseriate ; costal area with two rows of rather large areole, the margin obsoletely denticulate ; 
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 23, breadth 1 millim. 
Hab. Guatemata, Pantaleon (Champion). 
Four specimens. Allied to the North-American L. oblonga (Say), but much smaller, 
with two series of rather large areole in the costal area of the elytra from the base 
downwards, the median carina of the pronotum more raised than the outer ones. 
10. Leptostyla angustata, n. sp. (Tab. I. figg. 24; 24a, profile.) 
Very elongate, narrow, widening behind; body black, the integument white and hyaline, iridescent near the 
suture; the elytra with the nervures whitish in the costal area to beyond the middle and more or less 
fuscous elsewhere ; the antenne testaceous, with the basal joint (except at the tip), and the apical one 
also, black ; the legs testaceous, the apical joint of the tarsi infuscate at the tip. Head with five slender
