GORYBIA. 



Caput fere ad oculos Insertum. 

 Antennce corpore vix loiigiores, inermes. 

 Prothoi'cix subdepressus. 

 Tarsi postici breves. 



The retracted head and unarmed antennae 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 

 antennae 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. 



GovTjhia martes, 



G, ferruginea ; capite, prothorace, pedibusque fuscis, opacis ; apici- 

 bus elytrorum nigricaatibus, 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, im punctate, 

 blackish, and glossy ; propectus dull brown, rest of the under 

 and clavate portions of the thighs glossy reddish brown ; an- 

 tennae, tibiae, and tarsi dull brownish. Length 4 lines. 



PSYRASSA. 



Jntennce breviusculse, vel corpore vix longiores, art. S^'^-G^"* apice 



spinosis. 

 Prothorax oblongus, subcylindricus, haud tuberculatus, basi an- 



gustior. 

 Elytra angusta, elongata, apicibus bispinosis. 

 Femora haud clavata. 



This is a narrow form, more resembling Ihidion in habit than 

 Spharion ; the antennae 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 ;
