Two specimens collected by Mr. Champion at David in Chiriqui enable us to add 
this southern species to our fauna. 
Dinocoris piceus (p. 46). 
To the localities given, add:—Mexico, Teapa in Tabasco (H. H. Smith) ; Guate- 
MALA, Panzos, Chaco] (Champion); Panama, David (Champion). 
2(a). Dinocoris complanatus, n. sp. (Tab. XXXI. fig. 1.) 
Body above-and beneath, antenna, rostrum, and legs castaneous ; eyes dull ochraceous ; bases and apices of 
tibiee dull reddish. Head very coarsely punctate and rugulose at base; antenne with the second and 
third joints subequal in length, fourth and fifth longest, fourth a little shorter than fifth, which has its 
base dull ochraceous ; pronotum very coarsely punctate and slightly rugulose ; scutellum coarsely punctate 
and somewhat transversely rugulose; corium thickly and more finely punctate; membrane with the apex 
paler and extending beyond apex of abdomen; rostrum extending to the penultimate abdominal 
segment. 
Long. 12 millim. 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
This species is allied to D. piceus, Palis.-Beauv., but differs by its less convex and 
more flattened upper surface, the different relative lengths of the second and third 
joints of the antenne, &c. 
PRIAPISMUS, gen. nov. (To follow the genus Dinocoris, p. 47.) 
Allied to Dinocoris, but differing in not having the abdomen beneath provided with 
a distinct longitudinal furrow, and by the lateral margins of the pronotum being more 
or less convex and slightly recurved; scutellum with the apex rounded; membrane 
extending to, but not prominently passing, the apex of the abdomen. 
I have been compelled to propose this genus for the reception of two species, both 
from the State of Panama. Besides the above differential characters, Priapismus 
differs from Dinocoris by the smaller size of its species. 
1. Priapismus foveatus, n. sp. (Tab. XXXI. fig. 2.) 
Castaneous, varying in hue; eyes paler; antennz with the basal third of apical joint ochraceous. Antenne 
with the first and second joints shortest and subequal in length, third and fourth longer, subequal in 
length, but shorter than the fifth. Pronotum with a somewhat indistinct transverse impression on disk, 
on each side of which is a foveate impression near each lateral margin; pronotum and scutellum some-
