Broad oval, short, dull ; fuscous, the pronotum with the areole at 
the sides in front and behind, the areolz of the hood in part, the tip 
of the posterior process, and the three carine, a broad blackish patch 
on the median one excepted, more or less whitish and subhyaline; 
the elytra greyish, with a spot on the discoidal area before the apex, 
a patch on the costal area before the middle, and some spots or 
some of the nervures before and beyond it, black, the other portions 
of the costal area whitish and subhyaline with pale nervures, the 
nervures on the rest of the elytra blackish or fuscous ; the antenne 
testaceous, with the outer half of the apical joint black ; the legs 
testaceous, the femora black or piceous in the middle. Antenne 
with joints 1 and 2 stouter than the others, 2 much shorter than 1, 
3 very slender and elongate, 4 lanceolate and pilose, about as long 
as land 2 united. Pronotum closely punctured on the disc ; the 
membranous margins with 3—4 rows of small areolz ; the median 
carina strongly, the two outer carine feebly, foliaceous, the 
latter sinuous and connected anteriorly with a layer of mem- 
brane which fills the space outside the base of the hood; hood 
extending beyond the head, narrowed and strongly curved down- 
wards in front, rather widely reticulated. Elytra a little wider than 
the pronotum ; discoidal, subcostal, and sutural areas (the margin 
of the latter excepted) closely reticulated ; costal area slightly re- 
curved, with larger areole, the two rows diminishing to one at the 
apex. 
Length 21—23, breadth 13—1} millim. 
Hab.—LowrErR CALIFORNIA, Guadalupe (Bilimek, in 
mus. Vind. Cxs.). 
Three examples, two of which are from Guadalupe, the 
other without definite locality. The insect is not included 
in Prof. Uhler’s list of Hemiptera Heteroptera of Lower 
California [Proc. Calif. Acad. Sci. (2) iv, pp. 228-295 
(1894) ]. 
CoRYTHUCHA, Stal. 
Numerous closely allied American species belong to 
this genus. '!Monanthia lucida, Walk. (= C, fuscigera, Stal), 
and Tingis spinosa, A. Duges, both from Mexico, also 
appertain here. Stal’s type of C. fuscomaculata, from 
Brazil, is figured on Plate II, fig. 2. This last-mentioned 
insect is extremely like C. /usciyeru, Stal, but it appears to 
have the apical margin of the elytra less rounded, the 
inner portion being oblique.
