with their apices pitchy ; corium with a small dark spot on posterior portion of disk ; membrane greyish- 
brown, with the apex paler; body beneath and legs ochraceous; apex of the rostrum castaneous ; 
antennee with the second and fourth joints subequal in Jength; pronotum with the lateral margins

Long. 10 millim., lat. pronot. angl. 7 millim. 
Hab. GuatemMata, Volcan de Atitlan 2500 feet (Champion). 
This species, of which we possess but a single example, is allied to P. congrex, Stal, 
from which it differs in the greater length of the pronotal angles, the callosities on 
the anterior pronotal area, &c.

This species is distinguished from IJ. tartareus, Stél (a Mexican species already 
- enumerated and figured in this work), by the shorter second joint of the antenne and 
the more angulated apex of the scutellum ; the antenne have the fifth joint luteous at 
the base and a little longer than the fourth joint. 
M. tartareus does not appear to extend further south than Mexico, and the speci- 
mens collected in the State of Panama and recorded at p. 327, under the name of that 
species, should have been ascribed, as above, to M. picipes, Stal. 
3. Melanodermus castaneus, n. sp. 
Closely allied to M. picipes, but differing from that species in the following characters:—the body, legs, and 
antenne are castaneous, the third and fifth joints of the antenne are about equal in length, and 
considerably longer than the fourth joint, and the scutellum is a little longer. 
Long. 11 millim. 
Hab. Nicaraeua, Chontales (Janson). 
We have only received a single example of this species.
