2 next largest and longest, segment 3 with simple 

 appendage at distal extremity, segments 4 and 5 short, 

 subequal; color whitish, with strongly colored, dark 

 brown temples, angulated antennal bands, and lighter 

 brown, distinct signature, pointed behind, straight in 

 front; mandibles and oesophageal sclerite showing 

 through dark brown; trabecular and antennae paler 

 smoky brown. 



Prothorax short, quadrangular, wider than long, with 

 one pustulated hair in posterior angle; a large, nearly 

 square, dark brown, lateral transverse blotch nearly 

 covering each lateral half of the segment, the broad, 

 median line between them whitish. Metathorax short, 

 but little longer than prothorax; posterior margin 

 nearly straight, with five long pustulated hairs ranged 

 along each lateral fourth, the inner two of the hairs 

 may have only demi-pustulations. Sternal markings 

 consisting of distinct, blackish brown intercoxal lines, 

 and a pale brown, indistinct median blotch on meta- 

 thorax. Legs pale smoky brown with darker margins 

 and semiannulations. 



Abdomen elongate-ovate; segment 1 conspicuously 

 narrower than metathorax; one or two short hairs in 

 posterior angles of anterior segments, two or three long 

 hairs in angles of segments 5-9; ground color whitish 

 with broad, dark brown, lateral, transverse blotches on 

 segments 1-7, these blotches subquadrangular, but nar- 

 rower inwards, and leaving only a broad, median, whit- 

 ish, longitudinal line on middle of abdomen; in this 

 whitish space a few longish hairs on each segment; 

 rather large, uncolored, stigmatal spots in the trans- 

 verse blotches of segments 2-7; the transverse blotch 

 on segment 8 continuous across the segment and curv- 

 ing; segment 9 with two backward-projecting, short,
