expanded; hind head separated from fore head by an 

 angulated, rather broad pale transveral space; temples 

 unevenly bordered with blackish brown. 



Prothorax quadrangular, with posterior angles nearly 

 rectangular, with one long hair; brown with blackish, 

 even, lateral borders. Metathorax pentagonal, angu- 

 lated on abdomen; lateral angles with one short hair 

 and three long pustulated hairs, and two long pustu- 

 lated and one short pustulated on each postero-lateral 

 margin; brown, darker in anterior angles. Legs con- 

 colorous with palest color of the thorax, and with nar- 

 row dark dorsal margining. Sternal markings com- 

 posed of distinct intercoxal lines, a linear median 

 blotch on prothorax and a more distinct, larger median 

 blotch on metathorax. 



Abdomen elongate-elliptical; posterior angles of seg- 

 ments projecting slightly, with three or four longish 

 hairs beginning with segment 3; dorsal hairs of seg- 

 ment 1 arranged as follows: two on each side of the 

 median line (one in the inner anterior and one in the 

 inner posterior angle of each lateral blotch); segment 

 2 with four pustulated hairs along the posterior margin; 

 segments 3 and 4 with six pustulated hairs on posterior 

 margin; segments 5 and 6 with two pustulated hairs 

 near the middle of- the posterior margin, and a very 

 long hair on the posterior margin near the posterior 

 angles; segments with six pustulated hairs along the 

 posterior margin; segment 9 w^ith eight dorsal hairs 

 and four long marginal hairs; dark brown, with dis- 

 tinct narrow black lateral bands; a narrow uncolored 

 median line reaching nearly to posterior margin of seg- 

 ment 2; the dark brown transverse blotches on seg- 

 ments 6-8 broadly emarginated posteriorly; segment & 

 with elongate-elliptical transverse lateral blotches meet-
