282 HEMIPTERA-HETEROPTERA. 
8. Dysdercus oncopeltus, n. sp. (Tab. XXI. fig. 13.) 
Head red; antenne black, extreme base of first joint red, apical joint longest, third shortest, first a little longer 
than second. Pronotum black, with the lateral margins broadly and irregularly ochraceous. Scutellum 
and clavus black. Corium ochraceous, with a large transverse black macular fascia crossing at inner 
angle. Membrane black. Head beneath red; body beneath black; anterior and posterior margins of 
prosternum, posterior margins of meso- and metasternum, acetabula, and posterior margins of second, 
third, fourth, and sixth abdominal segments pale Juteous; legs black, cox red, rostrum piceous and 
reaching base of third abdominal segment. Anterior femora armed with two short spines near apex. 
Long. 13-14 millim, 
Hab. Panama, Volcan de Chiriqui, 4000 to 6000 feet (Champion). 
This is a very distinctly marked species, especially on the underside. As in many 
other species from Panama, the principal colour differences are of a decidedly melanic 
_ character.

Herrich-Schaffer’s drawing is so useless for any practical purpose, that we have re- 
figured the species, and also two of its varietal forms. The variation pursues a somewhat 
similar course as in other species. Thus in fig. 17 the scutellum is wholly ochraceous, 
in fig. 16 it has the base black, whilst it is wholly black in the Mexican specimen 
represented by fig. 18. A specimen from Costa Rica is represented by fig. 16; and 
fig. 17 refers to an example from Guatemala. . 
10. Dysdercus chiriquinus, n. sp. (Tab. XXI. fig. 22.) 
Body above obscure ochraceous ; antenne, scutellum, a rounded spot on disk of corium, near inner angle, and 
membrane black, the last with the apical margin whitish. Antenne with the extreme base of first joint 
ochraceous, first and second joints subequal in length, fourth longest, and third shortest. Extreme apex 
of head spotted with black. Pronotum with the anterior collar whitish, inwardly margined with black, and 
with the anterior lobe marked off by a very deep transverse incision. Head and body beneath ochraceous. 
Anterior and posterior margins of prosternum, posterior margins of meso- and metasternum, acetabula, and 
posterior margins of abdominal segments broadly whitish, which is more or less distinctly narrowly 
margined with black. Rostrum ochraceous more or less suffused with piceous, in the ¢ almost reaching 
_ fifth abdominal segment, in the . almost reaching abdominal apex. Legs ochraceous, tibiee and tarsi 
somewhat piceous. 
Long. ¢ 14 to 15 millim., 2 17 millim. 
Hab, Panama, Volcan de Chiriqui 2000 to 3000 feet and 2500 to 4000 feet (Champion).
