LEPTOSTYLA. 19 
two and a half times the length of 2, 2 very short. Pronotum with the membranous margins very 
broadly and arcuately dilated, recurved, widest at the middle, and with four rows of areol at this part, 
the areole small; hood short, oval, considerably raised; the three carinw feebly foliaceous, the inter- 
spaces closely punctured. Elytra gradually, arcuately widened from the base, the costal margin slightly 
hollowed at the middle, the apex rounded ; discoidal area not reaching the middle, subfusiform, closely 
reticulated ; subcostal area nearly as wide as the discoidal, triseriate; costal area with four rows of 
areole at the middle, diminishing to two at the base, the areole (like those in the sutural area) 
moderately large and not differing very much in size. 
Length 23, breadth 14 millim. 
Hab. GuatemaLa, Cahabon in Vera Paz (Champion). 
One example. This insect approaches L. difasciata, but has the pronotum more 
transverse, the membranous margins being much broader and with more numerous 
areole. The reticulation of the elytra is also more uniform and the markings quite 
different. The frontal spines are so small as to be scarcely distinguishable. 
13. Leptostyla bifasciata, n. sp. (Tab. II. figg. 3; 3a, profile.) 
Moderately elongate, broad ; body black, the integument testaceous and partly hyaline; the elytra with an 
oblique fascia before the middle, the apex (the large areolw excepted), and the space between the costal 
area and the inner margin thence to the base, fuscous or brownish, a spot on the discoidal area behind 
and the nervures on the dark portions of the elytra black ; the nervures of the hood and margins of the 
pronotum fuscous; the antenne testaceous (the apical joint broken off); the legs testaceous, the tarsi 
black. Head with a single slender frontal spine and two other shorter spines beneath it, the latter 
approximating at the tip; antenne long and slender, joint 1 about two and a half times as long as 2, 
2 very short. Pronotum with the membranous margins broadly and arcuately dilated, recurved, with two 
rows of moderately large areole ; hood rather large, broad-oval; the three carine feebly foliaceous, the 
interspaces somewhat sparsely punctate. Elytra moderately long, strongly, arcuately widening from the 
base, the costa thence to near the apex straight, the apex broadly rounded ; discoidal area subfusiform, 
not reaching the middle, closely reticulated; subcostal area narrower than the discoidal, irregularly 
triseriate; costal area with three or four rows of areole at the middle, diminishing to two at the base, 
the outer and inner areole at the middle larger than the others; the areole in the apical half of the 
sutural area also very unequal in size, two of the inner ones being very large and pentagonal. 
Length 33, breadth 17 millim. 
Hab. Guatemata, Senahu in Vera Paz (Champion). 
One specimen. Easily recognizable by the bifasciate elytra and the rather broadly 
dilated membranous margins of the pronotum. 
14. Leptostyla divisa, n.sp. (Tab. II. figg. 4*; 42, profile.) 
Moderately elongate, rather broad; body black, the integument whitish or pale testaceous and partly hyaline ; 
the elytra with an oblique fascia towards the apex, the space between the costal area and the inner 
margin thence to the base, and the nervures beyond the fascia, smoky-black or fuscous; the antenne 
testaceous, with the apical joint (except at the extreme base), and also the basal one, black; the legs 
testaceous. Head with two short slender frontal spines, approximating at the tip; antenne long and 
slender, joint 1 two and a half times as long as 2 and much shorter than 4, 2 very short. Pronotum 
with the membranous margins moderately wide, recurved, converging anteriorly, with two rows of 
areole ; hood short, oval, considerably raised ; the three carinz feebly foliaceous, the interspaces closely 
punctured. Elytra moderately long, arcuately widened from the base, rounded at the tip, the costal 
margin slightly hollowed at the middle; discoidal area rather short, subfusiform, closely reticulated ; 
subcostal area nearly as wide as the discoidal, closely reticulated ; costal area with three or four rows of
