8 HEMIPTERA-HETEROPTERA. 
the discoida]l area rather closely reticulated, tumid behind ; costal area with three rows of areole, the 
areole large, except towards the base, tetragonal or pentagonal. 
Length 33-34, breadth 2-21 millim. 
Hab. Mexico, Cuernavaca (Bilimek, in Mus. Vind. Ces.); GuaTeMaLa, Cahabon in 
Vera Paz, El Tumbador, Cerro Zunil, Pantaleon (Champion); Panama, Volcan de 
Chiriqui (Champion). 
Fifteen examples. Very like C. spinosa, but differing from it in having shorter and 
more slender spines along the margins of the pronotum and elytra, as well as on the 
nervures. The three specimens from Mexico are all more or less immature. Smaller 
than C. fuscigera, the elytra without a transverse fascia near the apex. C. hispida, Uhler, 
from Lower California, is also an allied form. A specimen from Chiriqai is figured. 
4, Corythucha spinosa. (Tab. I. figg. 9; 94, profile.) 
Tingis spinosa, A. Dugés, La Nat. (2) i. p. 207, t. 18. figg. 1-3 (1889) °. 
Hab. Mexico (Sallé), Guanajuato (Dugés1), Orizaba (Bilimek, in Mus. Vind. Ces.). 
Differs from C. fuscigera in having much longer and stouter spines along the lateral 
borders of the pronotum and elytra, as well as on the nervures, the pronotal hood 
much less inflated behind and more widely reticulated at the sides in front, and the 
maculation of the apical half of the elytra in the form of scattered spots. ‘The fuscous 
markings are probably variable, as none of our specimens quite agree with Duges’s figure 
in this respect. The details of structure of both sexes and the larva are figured by 
him. We figure a specimen from the Sallé collection. 
5. Corythucha setosa, n. sp. (Tab. I. figg. 10; 10a, profile.) 
Body black, the pronotum brown, except in front; the integument whitish or pale testaceous, the membranous 
margins of the pronotum and the elytra hyaline; the pronotum usually with one or two transverse 
marks on the margins and the crest of the hood, and the elytra with a transverse fascia a little below 
the base, and generally some of the nervures near the tip, brownish or fuscous; the antenne and legs 
testaceous; the pronotum with the margins, hood, and nervures, and the elytra with the costal margin 
to near the tip, as well as the nervures, armed with rather short. closely-set spines; the antennz with long 
bristly hairs. Pronotum with the membranous margins broad, reniform ; hood moderately large, gradually 
tapering forwards, not constricted at the middle, the reticulation uniform; median carina very feebly 
foliaceous, becoming still lower in front, the outer caring also very little raised. Elytra with the 
discoidal area closely reticulated, slightly tumid behind; costal area with three rows of areole, the 
areole large, tetragonal or pentagonal. 
Length 31-33, breadth 2-23 millim. 
Hab. GuaTeMaua, Quiché Mountains 7000-9000 feet, Volcan de Agua 8500 feet, 
Cerro Zunil, Calderas, Duenias (Champion). 
Not uncommon in Guatemala, at an elevation of from 5000-9000 feet above the 
sea. Differs from the other Central-American species in the much smaller, narrower, 
and gradually tapering pronotal hood, the very feebly raised median carina of the 
pronotum, and the less tumid discoidal area of the elytra. A specimen from Cerro 
Zunil is figured.
