Oloessa minula. (PI. III. fig. 4',) 

 O. fusca; elytris castaneis, piibe grisea variis; antennis pedi- 



busque fulvescentibus, nitidis. 

 Hah. — Aru. 



Head very dark brown, slightly corrugated in front, and without 

 the mesial line ; lip and epistome covered with pale silky hairs ; 

 eyes black, the two portions very remote, the upper somewhat 

 crescent-shaped, the lower rounded ;* prothorax dark brown, 

 shining, with a few distant punctures and scattered white slender 

 erect hairs, a narrow transverse groove at the base ; scutellum 

 triangular ; elytra dark chesnut-browji, slightly shining, a long 

 and slightly recurved spine at the base of each, directed upwards 

 and a little outwards ; between the spines and extending to the 

 middle of the elytra a thin greyish pubescence, bordered pos- 

 teriorly with white, in this space a few coarse punctures, rest of 

 the elytra nearly glabrous, except a few greyish hairs at the apex ; 

 body beneath dusky ; legs dark fulvous, shining ; antennae about 

 half as long again as the body, pale fulvous, shining, the seventh 

 and eighth joints dark at the tips, the remainder dark brown.

NiPHONINiE. 



The principal characters of this sub-family, which very nearly 

 corresponds with the " groupe Oncideritce" of M. J. ThomsoUj-f are 

 the large claw-joint and the ovate or shortly clavate scape. This 

 last character has not hitherto been noticed, I believe, but it 

 separates this sub-family from the Mcsosince, which have a long 

 cylindrical scape. I'he greater part of the genera, although fre- 

 quently composed individually of what may be termed '*Jine" 

 species, are generally of a rather commonplace appearance, and 

 they are, as might be expected, very difficult to limit. 



The Niphoninde have mostly a moderate-sized ovate head, more 

 or less transverse or subquailrate anteriorly, — tliat is, from the 

 vertex to the line of the inseilion of the epistome, — or it is very 

 large, flat or rounded in front, as in Abnjna, Oticidcrcs,X and otlier 

 genera. The antennary tubers commence near the eye, or some- 

 times arise near the mesial line when they become approximate 

 at the base ; they are cornuted in the males of Onc'ideics. The 

 eyes are almost invariably of moderate size and deeply emarginate.
