GORYBIA. 
Caput fere ad oculos insertum. 
Antenne corpore vix longiores, inermes. 
Prothorax subdepressus. 
Tarsi postici breves. 
The retracted head and unarmed antennez are the chief dia- 
gnostic characters of this genus; the former is very short, with 
the eyes prominent and adding considerably to its breadth; the 
antennee are unarmed, but the third, fourth, and fifth joints 
have each above half a dozen longitudinal ridges ; the prothorax 
is very much constricted posteriorly, and is without tubercles 
and spines; the elytra have the usual external spine at their 
apices; the femora are clavate ; the posterior tarsi shorter than 
the intermediate ; the first abdominal segment is twice as long 
as the second, instead of being only about the same length or a 
little longer. The specimen here described is probably a female. 
Gorybia martes. 
G. ferruginea ; capite, prothorace, pedibusque fuscis, opacis; apici- 
bus elytroram nigricantibus, nitidis. 
Hab. Espiritu Santo. 
Ferruginous, with sparse greyish hairs; head and prothorax 
opaque, brown, the former obscurely, the latter very distinctly 
reticulately impressed ; scutellum rounded ; elytra rather coarsely 
punctured at the base, ferruginous towards the apex, impunctate, 
blackish, and glossy; propectus dull brown, rest of the under 
and clavate portions of the thighs glossy reddish brown ; an- 
tenn, tibize, and tarsi dull brownish. Length 4 lines. 
PsyRassa. 
Antenne breviuscule, vel corpore vix longiores, art. 34°-6"™ apice 
co) 
spinosis. 
Prothorax oblongus, subcylindricus, haud tuberculatus, basi an- 
gustior. 
Elytra angusta, elongata, apicibus bispinosis. 
Femora haud clavata. 
This is a narrow form, more resembling Jdzdion in habit than 
Spherion; the antennz in the typical species are much shorter 
than the body, distant at their base, with their tubers nearly 
obsolete ; the eyes are prominent, and give the head a greater 
breadth than the prothorax; the latter is elongate, subcylin- 
drical, and without tubercles or spines; the elytra are narrow 
and nearly parallel, the apex of each terminating in two spines ; 
the femora are a little thickened in the middle, but not clavate ;
