214 HEMIPTERA-HOMOPTERA. 
or less distinct, variable, fuscous, longitudinal bands, the most distinct being an oblique band reaching 
from near the base to the suture about a third from the apex, where it takes a turn and joins the exterior 
margin, the part behind being fuscous and subhyaline; sides of the breast and abdomen whitish ; legs 
testaceous or fusco-testaceous. 
Long. 12-13 millim.; lat. ad hum. 3-3} millim. 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Our single example from Bugaba has the fuscous markings of the tegmina very 
different from what they are in the specimens from the Volcan de Chiriqui, and they 
are continued nearly to the apex; the process of the head, too, is scarcely so upright. 
A specimen from the Volcan de Chiriqui is figured. 
BASCARRHINUS, gen. nov. 
Elongatus, postice latior, capite maximo subtus excavato ; metopidio inter oculos angusto, in processum longum 
subtus profunde excavato, supra et ad latera canaliculatum ad apicem nonnihil dilatatum producto ; 
oculis parvis; pronoto magno, subrugoso, lateribus postice dilatatis, basi sinuaté, angulis posticis late 
rotundatis ; scutello magno; tegminibus ad apicem sensim dilatatis, remotius punctatis, venis leviter 
exstantibus ; tibiis excavatis. 
Elongate, with the head very large, subparallel before the eyes, which are small and then contracted in an 
obtuse angle to the apex, from which there extends a long process, which is gradually dilated in front ; 
the underside of the head and process are excavate, and the upperside of both is traversed by a channel, 
the sides also of the process being channelled ; pronotum with the sides raised and dilated behind, sinuate 
at the base, the posterior angles broadly rounded ; scutellum large ; tegmina gradually widened towards 
the apex, with remote and rather large, but not deep, punctuation, the veins prominent; tibie excavate 
on their outer margin. 
This is a very distinct genus, and may at once be known from Rhaphirhinus, apart 
from the general structure, by having the process of the head in the same plane with 
the vertex, and not recurved, except almost imperceptibly at the extreme tip. 
1. Bascarrhinus platypoides, sp. n. (Tab. XIII. fig. 11.) 
Fuscus, vertice obscure testaceo, capite subtus flavo-testaceo, processu et spatio ad basim hujus subtus nigro ; 
scutello testaceo variegato; tegminibus fuscis, subhyalinis, venis obscure rufescentibus; corpore subtus 
testaceo ; pedibus fuscis, femoribus posticis rufescentibus, anterioribus et intermediis testaceis. 
Lighter or darker fuscous, with the vertex and sometimes part of the pronotum obscurely testaceous ; under- 
side of the rostrum and a space at the base dark, the rest of the underside of the head yellow-testaceous ; 
at the base of the head and in the centre of the pronotum are two. small, light, longitudiral, testaceous 
patches; scutellum dark, variegated with testaceous; tegmina subhyaline, with reddish veins; legs 
somewhat variable in colour—in the type specimen fuscous, with the femora lighter, the posterior pair 
rufescent ; underside testaceous. 
Long. 18, sine processu 15 millim. ; lat. ad hum. 4 millim.
