346 HEMIPTERA-HETEROPTERA. 
elytra more or less ferruginous. The ochreous lateral patches on the pronotum often 
have a short dark marginal streak. Differs from P. perbosci (which also is without a 
well-defined carina between the eyes) in the rounded anterior angles of the pronotum, 
the larger ochreous patches at its sides, the less distinctly spotted margins of the elytra, 
and the smaller size; and from the Palearctic P. marginatus, Laty., in the anteriorly 
narrowed pronotum, the narrower head, the non-carinate face, the black labrum, &c. 
3. Pelogonus viridifrons, n. sp. (Tab. XX. fig. 14, ¢.) 
Broad ovate, black; the head from the ocelli forwards shining and of a brilliant metallic-green colour, the rest 
of the surface opaque ; the labrum and antenne, the sides of the pronotum narrowly, except at the lateral 
angles, the outer margin of the corium, the rostrum, some marks on the pleura, and the coxa, ochreous, 
the basal margin of the pronotum and the claval suture inclining to ferruginous, the pronotum, scutellum, 
and elytra also with some irregular bluish-grey markings ; the legs infuscate, with the base of the femora 
ochreous, in one specimen almost entirely ochreous; the upper surface with very minute scattered golden 
scales, the under surface with a bluish-grey pruinosity, the abdomen and legs with a bluish-white 
pubescence. Face densely, irregularly rugulose, carinate between the eyes ; the latter large, very prominent 
in the male, less so in the female. Pronotum, scutellum, and elytra sparsely, distinctly punctate; 
pronotum short, nearly twice as wide at the base as at the apex, the sides somewhat rounded and rapidly 
converging from the base, the anterior angles completely effaced, the lateral angles subacute and projecting 
a little beyond the elytra; elytra widening to near the middle; nervures of the membrane indistinct. 
Fifth ventral segment carinate down the centre in the male. 
Length 47-53, breadth 23-3,1, millim. (¢ 9.) 
Hab. Guatemata, Rio Naranjo, San Gerdénimo (Champion). 
A male from Rio Naranjo and a female from San Gerdnimo, the latter much the 
larger of the two, and with the legs almost entirely pale. The ochreous lateral streaks 
on the pronotum become, as usual, a little wider forwards. 
4. Pelogonus acutangulus, n. sp. (Tab. XX. figg. 15, 154, 2.) 
@. Broad ovate, flattened above, much narrowed behind, black; the head from the ocelli forwards shining, 
and of a brilliant metallic-green colour in front, changing to cupreous between the eyes, the rest of the 
surface opaque ; the labrum, the two basal joints of the antenne, the rostrum, the sides of the pronotum 
narrowly, except at the lateral angles, the outer margin of the corium, some marks on the pleura, and the 
coxe, ochreous, the basal margin of the pronotum ferruginous, the elytra with indications of the usual bluish- 
grey markings ; the under surface with a bluish-grey pruinosity, the legs and abdomen with a bluish-white 
pubescence ; the legs infuscate, the femora beneath and at the base ochreous. Head punctured behind 
the ocelli, the face densely, irregularly rugulose in front, the interocular space carinate down the middle 
and almost smooth; eyes comparatively small, not prominent. Pronotum, scutellum, and elytra very 
distinctly punctured ; pronotum short, about twice as wide at the base as at the apex, the sides straight, 
the anterior angles completely effaced, the lateral angles acute and projecting beyond the elytra; elytra 
narrowing from a little below the base; nervures of the membrane prominent. Legs long and slender. 
Length 53, breadth 24 millim. 
Hab. Guatemata, Rio Naranjo (Champion). 
One specimen, from the banks of the River Naranjo, in the “ tierra caliente” of the 
Pacific coast region. Easily separable from its allies by the acute lateral angles of 
the pronotum, the almost smooth interocular portion of the head, and the posteriorly 
narrowed elytra. .
