5. Broad-oval, somewhat convex, thickly, ivther coarsely pubescent, 

 the pubescence here and there clustered into denser patches (thus appearing 

 fasciculate) ; testaceous, variegated with piceous above (leaving the base, 

 suture, outer margin, and various iudefiiiite markings on tlie disc, testaceous), 

 the antennae (joints 1-3 excepted) and an anuuhis towards the apex of the 

 posterior femora also infuscate ; densely, very finely punctate. Head slightly 

 depressed on each side between the eyes, the latter moderately large ; antennae 

 rather sleuder, not very elongate, joint 3 small, barely as long as 2, Prothorax 

 uneven, very short, rapidly arcuately narrowed from the base, deeply hollowed 

 in front opposite the eyes. Scutellum somewhat convex. Elytra explanate 

 and sharply margined laterally, compressed and deeply excavate at the sides 

 beneath the prominent humeral callus, hollowed along the suture anteriorly, 

 distincth' gibbous behind this, and with a shallow sutural groove and indica- 

 tions of four feeble incomplete costae. Posterior coxae without plate. Posterior 

 legs long, the tibiae broad, compressed, curved, and sliarply carinate, the upper 

 spur about as long as the first tarsal joint. 



Length 3|-3|, breadth 2^ nun.

Described from a female in \qvj prood condition. An abraded, paler 

 example (d?), with longer, entirely testaceous antennae, and the dark 

 markings on the elytra reduced to a general suffusion on the disc, must 

 belong to the same species. The fasciculate or subfasciate arrangement 

 of the pubescence on the elytra may be partly due to abrasion. O. com- 

 pressa can be placed near the Bornean 0. gihhosa. 



22. — Ora coro7iata, n. sp. 



Hemispherical, shining, thickly cinereo-pubescent ; testaceous, the head, 

 prothorax, and scutellum piceons in one example, the elytra (except along the 

 thickened sutural margin) mottled with the same colour, the apical excavations 

 of 2 also infuscate; densely, finely, the elytra more coarsely, punctate. Head 

 broad, excavate on each side between the eyes, the latter large ; antennae long, 

 slender, joint 3 very small. Prothorax very short, exi)lnnnto laterally, and 

 deeply hollowed in front opposite the eyes, arcuately narrowed from the base, 

 the angles cljtuse, the anterior ones prominent, the surface uneven. Elytra 

 arcuately explanate laterally, depressed behind tlie scutellum, with four faint 

 incomplete costae on the disc and the suture thickened, the apices somewhat 

 acuminate in (S and very obtuse in $ ; the $ with a common, broad, deep, 

 antero-laierally furcate excavation before the tip, formed by a common anauhir 

 depression on the suture and an oblique, short, broad sulcus exterior to it on 

 each elytron, the depressions separated by an oblique plica. 



Length 3tV 3^, breadth 3 mm. (d $ .)
