about as long as the four preceding combined. Prothoraa', widely

 very distinct, and commencing in a small fovea, dorsal stria repre- 

 sented by a large basal fovea only; epipleural furrow deep, lightly 

 curved, and terminated close to base and apex; punctures rather 

 indistinct. Metasternicm impressed between hind coxje. Abdomen 

 convex along middle. Legs unarmed and comparatively thin.

In size, colour, and antennae like R. pallida, but otherwise very 

 different. There are tln-ee specimens before me, api:)arently all 

 females; but I have described them, as the large prothoracic fovese 

 should be very distinctive; the medio-basal fovea occupies fully 

 half the width of the prothorax, is straight behind, and arched in 

 front.

9. Bright reddish-castaneous, elytra and appendages paler. 

 Tip of elytra, base of abdomen on under-surface, and part of 

 under-surface of head with dense, short pubescence, upper surface 

 of abdomen with .sparse pubescence, elsewhere almost or quite 

 glabrous. 



Head with a wide median groove not quite extending to base, a 

 feeble elevation between eyes. Antennae extending to middle 

 coxa?; second joint shorter than first, but no narrower; ninth 

 subovate, about once and one-half the length and almost twice 

 the width of eighth; tenth slightly larger than ninth, but much 

 the same shape; eleventh not as long as the two preceding joints 

 combined, its apex obtuse. Palpi long and thin, club of apical 

 joint about one-half the length of peduncle. Prothorax slightly 

 longer than wide; close to base with a moderately wide, transverse
