'114: [November 



Vith black. Antennas rufous, first joint long and clavate, second joint 

 very short, third and fourth equal, both together about as long as the first, 

 fifth and following joints suddenly larger and strongly serrate, last joint 

 attenuated. Thorax black, finely punctured, clothed with whitish pubes- 

 cence, convex, sides rounded ; two small tubercles on each side ; on the 

 disk there are apparently three series of interrupted, transverse, acute 

 carinae; a rufous spot beneath between the anterior coxae. Scutellum 

 black, margined with whitish. P]lytra slightly attenuated posteriorly; vel- 

 vety-black, brownish about the base ; a narrow, somewhat oblique, whitish 

 band extending from the humerus to the suture down which iT continues 

 to the anterior third, where it becomes suddenly augulated upwards and 

 then downwards, forming half of the letter M ; a little above the posterior 

 third, on the suture, there is a houk-shaped white mark which is sudden- 

 ly dilated at the posterior fourth into a knob, from thence it margins 

 the suture and tip of the elyti'on ; a small dot at the posterior thix-d near 

 the lateral margin (which nuiy, in some specimens, become confluent with 

 the hook-shaped mark, nearly opposite, on the suture) ; tip rounded from 

 the suture and armed with a strong acute spine. Postpectus and abdomen 

 rufous, blackish on the sides ; between the middle coxse commences a nar- 

 row, oblique, white band which extends along the side of the postpectus, 

 and reaches the niargin of the elytron where it suddenly expands into a 

 knob; a white spot behind the posterior coxaa, and two very small, appi*ox- 

 imate white spots before and between the coxae ; first, second and third 

 segments of the abdomen marked on the sides with white, the second seg- 

 ment bearing the largest mark. Coxae and legs rufous, hairy, posterior 

 pair very long; femora clavate, muricate and armed at their tips with two 

 strong acute spurs which are obsolete on the anterior pair ; posterior fem- 

 ora tipped with black ; tibise flattened, terminal spurs long and acute on 

 the posterior pair. Length 5 J lines. 



The markings on the elytra and abdomen are composed of white scale- 

 like hairs which lie close to the surface of the body. This species belongs 

 to Chevrolat's division, Rhopalomerus.
