PROXIUS.—CARVENTUS. 71 
Hab. GuatemMata, Senahu in Vera Paz, Zapote (Champion); Panama, Bugaba 
(Champion).—VENEZUELA!. 
Seven examples. One of those from Bugaba has an additional transverse prominence 
on each side of the disc of the posterior lobe of the pronotum, and the anterior angles 
of the latter, as well as the post-ocular portions of the head, more acute. 
This species may be separated from P. personatus by the shorter third joint of the 
antenne (this joint not being longer than the fourth in the present insect), the more 
strongly bifurcate prominence on the middle of the anterior part of the pronotum, the 
posterior lobe of the latter being margined towards the sides in front as well as behind, 
and with differently shaped callosities on the disc, the uninflated median prominence 
on the scutellum, the more produced apical angles of the sixth abdominal segment, &c. 
A pair from Bugaba are figured, showing the extreme forms. 
CARVENTUS. 
Carventus, Stal, Hemipt. Afric. iii. p. 82 (1865) ; Enum. Hemipt. iii. pp. 1389, 140 (1878). 
Of the six described members of this genus, all are eastern but one, C. mexicanus, 
Bergr. The American species closely resembles Stal’s type of C. denticollis, from 
Mysol (now before me); but it is without the abruptly projecting tooth at the middle 
of the sides of the pronotum, and also has the post-ocular portions of the head longer 
and the apical lobes of the pronotum emarginate in front. 
1. Carventus mexicanus. (Tab. V. figg. 10,¢; 11,2.) 
Carventus mexicanus, Bergr. Wien. ent. Zeit. xiv. p. 167 (3) (1895) *. 
Hab. Mexico, San Marcos (Bilimek, in Mus. Vind. Ces.: 3+); Panama, Volcan de 
Chiriqui 3000 feet (Champion : @ ). 
The type (6) of this species, communicated by Dr. Bergroth, is not in good 
condition, the incrustate portions of the head and pronotum being apparently injured 
or not fully developed. A description of the female is now given from the better- 
preserved specimen from Chiriqui :— 
2. Oblong-ovate, ferrugineo-fuscous, the head, the anterior lateral lobes of the pronotum, the sides of the 
scutellum, and the connexivum covered by a thick greyish-ochreous incrustation ; the antenne ferrugineo- 
testaceous, the legs testaceous. Head broad, subtriangular, the sides of the narrow basal portion obliquely 
converging posteriorly ; the post-ocular portions swollen and dilated laterally to beyond the eyes; the 
antenniferous processes long, spiniform, subparallel; the apical lobes long; the callosities forming a 
rather broad median ridge, enclosing a rostriform process in front; antenne slender, joint 1 moderately 
stout, extending to nearly one-half beyond the apical lobes of the head, clothed with a few short hairs, 
2 rather more than half the length of 1, 3 about two and one-half times the length of 2, 4 a little longer 
than 2, clothed with long hairs at the tip. Pronotum transverse, trapezoidal; the anterior lateral lobes 
obliquely emarginate in front and also emarginate at the sides, with prominent angles, the callosities with 
punctiform impressions; the posterior lobe slightly dilated and callous at the sides, not incrustate.
