rounded, but flattened, with a small dark blotch near the 

 front. Lateral emarginations shallow with anterior angles round- 

 ed and surrounded by a large, dark chestnut to black blotch. 

 Temples rounded, with indication of an angle behind, bearing 

 a long marginal hair and, probably, a long surface hair, a dis- 

 tinct pustule being present. Occiput concave, with two short 

 hairs and marginal blotches but little colored. Mandibles small 

 but heavily chitinized ; surface of head with a number of 

 short hairs. 



Thorax about as long as head. Prothorax shorty flattened 

 behind, with ten hairs ; there are also two short spines at the 

 sides and a long spine in the anterior angles. Metathorax quite 

 large, hexagonal, broader than long ; on the anterior lateral 

 margins are several spines, while behind is a series of about 

 twelve marginal hairs ; there are also several lateral surface 

 hairs. Legs pale in color, with narrow tibiae ; mesothoracic 

 pair missing in the specimen at hand. 



Abdomen elliptical with yellowish transverse bands, inter- 

 rupted submarginally, leaving a clear space running parallel to 

 the margin of the abdomen ; continuations of these transverse 

 bands, laterad of the clear space, form indefinite lateral blotch- 

 es ; lateral blotches on last segment lacking, the median band 

 nearly covering the entire surface. Last segment longer than 

 the preceding, rounded, bearing two extremely long hairs, shown 

 curved forward in the accompanying figure, and several short 

 marginal ones ; the two preceding segments also bear a long 

 hair on each side ; dorsal hairs on each segment weak.
