Duefias, Capetillo (Champion), Coban (Conradt). 
Not rare in Mexico and Guatemala, occurring on both the Atlantic and Pacific 
slopes. The types of St&l and Walker have been examined; the latter is mutilated 
(as noted by Walker himself), the pronotal hood, &c. being broken off. We figure 
a specimen from San Juan in Vera Paz, a facsimile of Stal’s type.

In this small species the discoidal area of the elytra is more widely reticulated than 
in the other Central-American members of the genus. Some specimens have the 
median carina of the pronotum moderately foliaceous (it being much less prominent 
than the hood, when viewed laterally), and the nervures of the elytra distinctly marked 
with fusco-testaceous; while others have the median carina very strongly foliaceous 
and the elytral nervures faintly marked with testaceous. Both forms were obtained at 
Pantaleon. C.decens is probably a variety of C. gossypz (Fabr.) ; the type is immature. 
An example from Guatemala city is figured. 
3. Corythucha unifasciata, n. sp. (Tab. I. figg. 8; 84, profile.) 
Body black, the pronotum brown, except in front; the integument whitish or pale testaceous, the membranous 
margins of the pronotum and the elytra in great part hyaline; the pronotum with the nervures of the hood 
and two transverse marks on the margins, and the elytra with a transverse fascia a little below the base, 
some small spots or some of the nervures near the tip, and sometimes one or two spots on the discoidal 
area, brownish or fuscous; the legs and antenne testaceous, the latter with the apical joint usually 
darker; the pronotum with the margins, hood, median carina, and nervures, and the elytra with the 
costal margin to near the apex, and also the nervures, armed with rather short closely-set spines, those 
on the margins of the pronotum and elytra becoming shorter behind; the antenne with long bristly 
hairs. Pronotum with the membranous margins broad, reniform ; hood large, abruptly constricted at the 
middle, tapering in front and globose behind, widely reticulated, the reticulation becoming much closer 
at the sides in front; median carina strongly foliaceous, the outer carine raised anteriorly. Elytra with
