A black and yellow green colored species ; fresh specimens conspicuously 

 pruinose. 



Head black, with the following yellowish tinged with green : a spot above 

 the base of each antenna, a central triangular spot in front of the ocelli, an 

 irregular spot of a little lighter color on each side near the eye and con- 

 tiguous to the hind border, and a small spot on the front above the transverse 

 rugK. Pronotum yellowish green with a large central black spot which is 

 broadened near the front margin, and to a very much less extent on the 

 hind margin where it extends on to the collar. In some of the paratypes this 

 black spot contains one of a yellowish green color. On either side the grooves 

 are blackened, and the hind margin or collar is blackened in the center, as 

 mentioned above, and has a black spot each side at the humeral angles. Meso- 

 notum black with the central W-shaped mark near the front margin yellowish 

 green in color; behind this is the elevated x also yellowish green and with 

 the anterior marks extending well forward and nearly touching the W-mark. 

 The sides near the base of the fore wings are also yellowish green. Tergum 

 black with an indication of a dorsal row of pruinose spots faintly defined ; 

 sides of the abdomen irregularly bordered with yellowish green, the last seg- 

 ment being nearly all of that color except the central area which is darkened. 

 The fore wings have the costal margins yellowish green nearly to the extremi- 

 ties of the wings and the subcostal veins are blackened ; the first and second 

 cross veins are darkened, but not conspicuously so. The basal areole of each 

 fore wing contains a short darkened dash of color, otherwise they are nearly 

 clear; the flaps of both the fore and hind wings are grayish white. Beneath
