Male. Deep black ; two lines between the eyes, a spot on the 

 front, three stripes on the prothorax (the lateral ones shorter and 

 narrower), a sutural patch expanding below the middle into a 

 broad band, and sides of the thorax beneath, white ; antennae 

 four times as long as the body, base of the fourth and fifth joints 

 white ; tarsi with the base of the first and second joints of the 

 four posterior, and the base of the last of the posterior only, 

 whitish-cinereous. In the female, the white on the prothorax is 

 more diffused, shading gradually into the black, and the whole 

 of the upper two-thirds of the elytra is white, except at the 

 shoulders and two black spots near the centre of the patch ; the 

 tarsi have all the joints, except the penultimate, whitish at the 

 base. Length 10 lines.

 except the three last, which are somewhat stouter; antennal groove 

 broad, commencing beneath the lateral process, and continued

 verse, width of the elytra, semicircular anteriorly, narrowed sud-
