HEM1PTERA-HETEROPTERA. 369 
very much shorter spines to the lateral margins of the pronotum and abdomen, and 
the less produced and spinous lateral angles of the pronotum. Mr. Smith sent us one 
fully developed specimen from Tierra Colorada, and an immature form from Omilteme. 
8. Vilga dissimilis, n. sp. (Tab. XXXIII. fig. 21.) 
Pale fuscous, posterior margin of pronotum, lateral margins of scutellum, apical joint of antenne, and the 
femora dark fuscous ; scutellum reddish-ochraceous, with its apex greyish-white ; connexivum brownish- 
ochraceous. The antenne have the three basal joints prominently setose, but the basal joint is not 
spinose ; the first and third joints are subequal in length, or the third is a little longer than the first, the 
second and fourth joints are almost subequal in length; the pronotum has the lateral margins longly 
setose but not spinous, the lateral angles are produced in acute spines, slightly directed forwardly and 
upwardly ; the connexivum is distinctly spined at the segmental incisures; the legs are prominently and 
distinctly setose; the pronotum and corium are coarsely punctate, the scutellum less strongly so. 
(Underside of the body imperfectly seen, the specimen described being carded.)

Hab. Panama, David (Champion). 
This species is somewhat divergent from the typical form of the genus, by the 
condition of the basal joint of the antenne, which is setose, not spinous. 
4, Vilga divaricata, n. sp. (Tab. XX XIII. fig. 22.) 
Brownish-ochraceous ; two central longitudinal lines extending through head and pronotum, basal margin of 
pronotum, lateral margins of scutellum, a small excavated spot beneath the inner angle of the corium, and 
the segmental incisures to the connexivum dark fuscous ; the tibie are paler in hue, with their bases and 
apices darker. ‘The antenne are very obscurely setose, the third joint a little longer than the first and 
the fourth a little shorter than the second; the pronotal angles are very acutely produced and directed 
forwardly and upwardly; the lateral margins of the connexivum are prominently spined at the 
segmental incisures. 
Long. 7 millim. 
Hab, Panama, Volcan de Chiriqui 3000 feet (Champion). 
A single specimen of this insect was obtained by Mr. Champion. It differs principally 
from the preceding species by the more prominently and acutely spined lateral angles 
of the pronotum, whilst the basal joint of the antenne is even less setose and altogether 
non-spinous. It is clear that the diagnosis of St&l’s genus Vilga will have to be less 
strictly defined, or more generic division will be necessary.
