•rather sparse pale pubescence; in addition, with some longer hairs 

 scattered about. 



Head with a deep, round, closed fovea, of moderate size, close 

 to each eye; and with a distinct interantennal depression. 

 Antennae with second joint subglobular, fifth slightly longer than 

 fourth or sixth, ninth slightly longer and wider than eighth, 

 tenth larger and trapeziform, eleventh rather briefly truncate- 

 ovate, about as long as ninth and tentli combined. Prothorax 

 distinctly transverse, widest and strongly rounded close to apex; 

 with a large fovea on each side near base, and a somewhat 

 smaller one in middle, the three connected by distinct curved 

 lines; extreme base with a row of rather coar.se but partially 

 •concealed punctures. Elytra rather wide, dilated to bej'ond the 

 middle; with eight small basal fovese; dorsal striae deep at base, 

 but less distinct elsewhere than usual; punctures sparse and 

 indistinct; marginal stria deeper than usual but epipleural furrow 

 absent. Upper surface of abdomen witli a transversely elongate 

 medio-basal node, from each side of which pi-oceeds a distinct 

 •oblique stria; lower sui-face with a feeble depression in middle of 

 second segment. Metasternum widely and rather strongly con- 

 cave. Middle trochanters acutely dentate ; four front tibise 

 moderately stout, tlie hind pair decidedly thinner and spinose at 

 Apex, Length l^-l|nim. 



5. Differs in having shorter antennae, with the club somewhat 

 smaller, under surface of abdomen moderately convex, meta- 

 sternum depressed along middle only, and legs unarmed.

In appearance somewhat like large specimens of R. 6-foveata 

 and R. electrica, but the three subbasal fovese of prothorax con- 

 spicuously joined together, although the connecting lines are 

 rather less deeply impressed than usual. 



The longer hairs appear to be absent from some of the speci- 

 mens before me, but are really present, being pressed down 

 amongst the pubescence, this being due to the treatment received. 

 One specimen is entirely pale castaneous, j)robably from imma-
