in front of the eyes, the different shape of the posterior lateral angles of the pronotum, 
and the length of the scutellum, which slightly passes the apex of the corium. 4. 
signoreti differs in some slight respects from the generic diagnosis of Dr. Mayr, as in 
the length of the rostrum; but as that diagnosis was based on one species only, I have 
felt no hesitation in including this species in the genus. | 
PELIDNOCORIS. 
Pelidnocoris, Stal, Ofv. Vet.-Ak. Férh. 1867, p. 501; En. Hem. ii. p. 10 (1872). 
This genus now comprises but one species, and is thus, according to our present 
knowledge, restricted to Mexico. The basal joint of the antenne does not reach the 
apex of the head, thus agreeing with the previous genus; the pronotum, however, as 
described by Stal, has “angulis lateralibus productis, marginibus lateralibus anticis 
foliaceis, lobatis.” The head also is described as ‘‘ad oculos spina longa vel lobo 
spiniformi armato, jugis tylo longioribus, ante hunc contiguis.” I have not been able 
to examine a specimen of this genus; but the above characters, abstracted from Stal’s 
full generic diagnosis, are, apparently at least, characteristic.

This genus, as thus constituted by Stal, has the basal joint of the antenne extending 
beyond the apex of the head; this character, with the structure of the head, will at 
once separate Hmpicoris from Dinocoris. 
About eight species are known, all confined to the Neotropical Region, one only 
having been as yet recorded from Central America. _
