160 HEMPITERA-HETEROPTERA. 
acute, with the apices fuscous. Scutellum with the basal angles fuscous, a central longitudinal linear series of 
dark punctures, and with the apex produced into an obliquely erect, slender, acute, fuscous spine. Corium 
sparingly but somewhat coarsely punctate ; membrane bronzy. Underside of body and head pale ochraceous, 
thickly covered with dark punctures; disk of sternum fuscous; abdomen with a central and two sub- 
marginal obscure and subobsolete pale lines. Rostrum reaching posterior cox, with the apex black. 
Legs pale ochraceous, spotted with fuscous. 
Long. 8-9 millim. 
Hab. Guatemaua, San Gerdénimo, Zapote, Senahu (Champion). 
- This species appears to be nearest allied to C. picticeps, Stal, from which it differs by 
the basal joint of the antenne distinctly passing the apex of the head. 
PROTENOR. 
Protenor, Stl, Ofv. Vet.-Ak. Férh. 1867, p. 543; En. Hem. iii. p. 88 (1873). 
The unproduced and unarmed lateral angles of the pronotum separate this genus 
from Cydamus ; the lateral lobes of the head are exserted and much longer than the 
central, the head being subequal to or a little longer than the pronotum. 
One Nearctic species has been described; a second species is here added, from 
Central America. | 
1. Protenor tropicalis, n. sp. (Tab. XVI. fig. 3.) 
Pale ochraceous. First, second, and third joints of antenne subequal in length, with their apices somewhat . 
fuscous; fourth longest, fuscous, with the base pale luteous. Head sparingly punctate and obscurely 
transversely striate; lateral margins and a central longitudinal impression pale luteous. Pronotum 
thickly punctate (excepting an almost levigate transverse space near anterior margin); lateral margins 
and a central longitudinal slightly raised line pale luteous. Scutellum sparingly punctate. Clavus 
somewhat thickly punctate. Corium with the punctures arranged in somewhat irregular longitudinal 
linear series. Membrane bronzy. Underside of body concolorous; lateral margins of head, sternum, and 
abdomen somewhat thickly punctate, the sternum most coarsely, and the abdomen most finely so. Legs 
pale ochraceous. 
Long. 11-12 millim. 
Hab. Guatemata, Las Mercedes (Champion). 
| DARMISTUS. 
Darmistus, Stal, Ofv. Vet.-Ak. Forh. 1859, p. 469; ib. 1867, p. 543; En. Hem. iii. p. 88 (1873). 
Darmistus differs from Protenor by the lateral lobes of the head being very little 
longer than the central, and in having the basal joint of the antenne shorter than the 
second joint. But one species is known at present.
