infra omnino griseo-sericeus. 

 Hab. — Morty. 



Covered above with a silky pubescence, disposed in 

 patches of gray and silvery-gray, each varying in shade 

 according to the light; head broad in front, the eyes 

 very near the mandibles ; prothorax sparsely punctured, 

 a short black line in t.he middle, the sides darker than 

 the centre; scutellum nearly scutiform; elytra with 

 fine punctures nearly disappearing posteriorly, on each 

 elytron about three lighter patches, but more numerous 

 and indefinite in certain positions ; body beneath uniform 

 silky-gray, the throat and breast with longer hairs inter- 

 mixed ; legs and antennae with a fine grayish pile, slightly 

 silky ; femora ( c? ) extending beyond the elytra.

POLYPHIDA. 



A Glaucyte difi'ert ut sequitur ; caput antice produc- 

 tum ; protliorax cylindricus, capite angustior ; elytra 

 angustata, fere parallela; mesosternum antice ro tun- 

 datum. 



The habit of this genus is more like that of Demonax 

 among the Olytince than of Glaucytes. The male has the 

 antenn88 a little longer than the body, while in the female 

 they are a little shorter; and the difference in the latter 

 sex is most marked in the fourth joint, which is remark- 

 ably short.
