straight and bare; general color of the head golden 

 brown, a narrow, irregular, marginal border on the cly- 

 peal front, darker on the inner margin; a weak brown 

 band across the head in front of the antennal bands, 

 which are narrow and distinctly dark golden brown; 

 small ocular blotches and temples with very narrow 

 dark brown borders. 



Prothorax quadrangular, with rounding, posterior 

 angles, each with one hair; transverse blotches golden 

 brown, darker on the lateral margins and in the ante- 

 rior and posterior angles; a broad, pale, median line 

 separating the transverse blotches. Metathorax more 

 than twice as long as the prothorax, and as wide as the 

 head; sides diverging but little; a slight constriction 

 near the anterior angles; a series of hairs on the round- 

 ing posterior margin; same golden brown as the pro- 

 thorax, a narrow marginal border and a small brown 

 spot in the anterior angles, a narrow but well defined 

 border on the posterior half of the metathorax, the 

 anterior ends bending in, making the slight constric- 

 tion appear more than it really is. Legs paler golden 

 brown than the thorax, with very narrow marginal bor- 

 ders of dark brown. 



Abdomen narrow, elongate, with parallel sides, not 

 tapering till segment 7; segment 1 narrower and shorter 

 than those that follow; posterior angles but little ex- 

 tended, with one or two fine hairs; four long pustulated 

 hairs on the posterior margins of the segments; trans- 

 verse bands on segments 2 to 8 are golden brown, dark- 

 ening towards the lateral margins where the lateral band 

 is dark, narrow, and clearly defined; segments 7 to 9 

 without lateral bands; a pale transverse median band, 

 caused by the uncolored stigmatal spots, thus the trans- 

 verse blotches appear like two dark bands across each
