74 HEMIPTERA-HETEROPTERA. 
Hab. Guatemata, San Gerénimo (Champion). 
Allied to A. apta, Walk., differing in the shape of the body and scutellum, the central 
lobe of the head being shorter than the lateral, and in the colour of the legs, &c.; from 
A, crucigera, Hagl., it is distinguished by the shorter rostrum and the colour of the 
antenne ; it is also allied to A. rufifrons, Dall., but is separated from that species by 
the smaller and more convex body, smaller head, the basal joint of antenne being 
concolorous, and the lateral margin of pronotum less reflexed. 
5, Arocera affinis, n. sp. (Arocera protea, var. Tab. VII. fig. 19.) 
Closely allied to the preceding, but head wholly black, and central and lateral lobes subequal im length; trans- 
verse band of corium broken, sinuated and abbreviated posteriorly, and preceded by a small rounded spot ; 
scutellum with the apex testaceous. 
Long. 10-12 millim. 
Hab. Mexico (Bilimek, Mus. Vind. Ces.); GUATEMALA, San Gerénimo (Champion) ; 
Nicaragua, Chontales (coll. Dist.). 
In some specimens the transverse band of the corium is entire, as in the preceding 
species ; but the relative lengths of the lobes and the colour of the head prevent them 
from being confused with that species. A Guatemalan specimen is figured. 
6. Arocera patibulata, n. sp. (Tab. VII. fig. 17.) 
Head black, elongate, lobes subequal in length, impunctate, transversely striate about centre; lateral lobes 
hollowed and concave at apex. Antenne black; first, second, third, and fourth joints gradually increasing 
in length, fifth wanting, third joint clavate, fourth uniformly thickened. Pronotum black, sides raised 
and reflexed, with a large crucigerous prasinous fascia or disk; scutellum black, ornamented with a cru- 
cigerous fascia, prasinous in colour, extending from base to apex (the apical portion much narrowed) and 
fully across disk. Corium black, with a deeply sinuated basal spot, apical half irregularly defined, and 
apical two thirds of claval margin prasinous. Membrane black, with the apical border white. Connexivum 
alternately orange and black. Abdomen beneath orange-yellow, with a longitudinal row of transverse, 
central, segmental fascie, gradually diminishing in width from base to apex, a stigmatal row of rounded 
spots, a marginal segmental row of obconical spots (gradually decreasing in size from base to apex), 
sternum, rostrum, and legs black. 
The rostrum about reaches posterior cox, the second joint of which is the longest. Body above smooth, sub- 
levigate. 
Long. 12 millim. 
Hab. Costa Rica, Irazu (Rogers). 
Besides its very different colour and markings, the anteriorly concave surface of the 
head, and the greater length of the same, are positive characters by which to separate 
A. patibulata from the two preceding species.
