24 DESCRIPTION OF NKW I'.UPRP^STID.l"., 



lougiludinal impression betweeu the eyes, so usual in the genus, 

 seems in this species to be tilled up with a yellow mass ; the 

 antennae are blue, the thorax which is also of a brassy black, is 

 punctured very finely, the dorsal line is smooth, and yellow 

 towards the base, the sides are also yellow, as is a small part of 

 the anterior margin near the anterior angle ; the posterior angles 

 are slightly tipped with black, the yellow margin also widens 

 gradually towards the base. The elytra are yellow, and striato- 

 punctate, rather broadly truncated, with a minute tooth at the 

 external angle of the truncature, on each side behind the shoulder, 

 there is a long semicircular spot of a violet black, a narrow basal 

 margin, the suture, the apex, and a post-medial fascia are of the 

 same colour ; the sutural vitta swells out into a lozenge shaped 

 spot, immediately behind the scutellum, and the dark apical por- 

 tion is one-fourth of the whole length of the elytra. The under 

 surface is mostly yellow, the sides of the mesosterum and abdo- 

 minal segments are spotted with green, and the hinder margin of 

 these last are of the same colour ; the thighs are red ; the tibige 

 blue and red ; the tai'si blue.

 The head is brassy black, and punctured, a broad impression 

 extends along the face from near the vertex ; the antennae are 

 blue ; the thorax, which is very finely punctured, has a rounded 

 transverse gibbosity in the centre, as in 8. yilbosa, though not 

 to such an extent ; the centre of the thorax is of a brassy black, 

 broadly margined laterally with red ; the elytra are of aminiatous 

 red, striated and punctui'ed, towards the apex rounded and 

 serrated with two very minute approximate dentations at the 

 sutural angles, a large triangular almost black patch extends 

 from the base to the middle of the elytra , a small spot a little 

 behind the middle of each elytra, and the apex, are of the same 

 hue. The whole under surface is of a brilliant steel blue.
