The specimens vary to a certain extent in width and size, but I 

 am unable to pick out any distinctive masculine features. Some of 

 them are so encrusted with mud that the clothing is almost con- 

 cealed. The clothing appears to be usually of a dingy whitish grey, 

 more or less variegated with brown, but on some specimens it is 

 of a chocolate brown, variegated with ochreous. On the legs it is 

 usually prettily variegated On the abomen it is usually dark brown, 

 with three pale sti'ipes. On perfect specimens the entire surface is 

 covered with pubescence, rather denser on the granules than 

 elsewhere; with each granule crowned by a seta. The suture at the 

 base slopes rapidly downwards, and is not at all produced; the 

 projections on each side of the base and on the third interstice and 

 shoulder, are very strong, of almost equal size, and directed slightly 

 inwards. From above the posterior declivity appears to be vertical, 

 with its upper edge having a peculiarly jagged appearance. 



610. MYTHITES GRANULATUS n. sp. 



J". Black. Clothed with dingy brownish setae; but with a ridge 

 of dense blackish setse, or short hair, extending from apex of 

 abdomen to between middle coxae. 



Head with a deep median groove, and with two or three some- 

 what oblique ones on each side. Rostrum separated from head by a 

 deep transverse impression; with a deep median channel, widely 

 dilated in front; each side of base with a deep triangular notch. 

 Prothorax slightly wider than long, sides rather slightly rounded ; 

 disc somewhat flattened ; with numerous granules of irregular sizes, 

 and nearly always free, larger near (but not at) apex than elsewhere ; 

 with a distinct, but not wide or sharply defined median channel. 

 Elytra somewhat flattened, at base very little wider than prothorax, 

 sides gradually increasing in width to about the middle; with large, 

 irregular punctures or fovese; alternate interstices distinctly i-aised 

 and densely granulate, elsewhere withsparse granules; six tubercles 

 overhanging the posterior declivity, and four projections at base. 

 Length 14-17 mill.

Fairly close to a species I have as asperatus, but with very dense 

 elytral granules, and with conspicuous tubercles. Pascoe says of 

 asperatus that it diflers from basalis and sulcicoUis in the absence of 

 the larger conical tubercles. 



The lateral grooves on the head, although pronounced and fairly 

 deep, are certainly subject to variation. On the type there are two 

 deep grooves on the left side, the outer one of which, however, is
