cipital bands bending outward anteriorly, and a narrow 

 black line bounding the oral fossa. 



Prothorax, narrow, short; lateral angles obtuse, pro- 

 duced, and with a spine and long hair; in latero-posterior 

 angle a long hair, and in addition two posterior marginal 

 hairs on each side of the middle ; color dark brown with 

 narrow black lateral border, and a very narrow transverse 

 line across the segment in front of the middle. Meta- 

 thorax, sides bare, posterior angles with two spines and a 

 long hair; posterior margin with a few hairs; color dark 

 brown with darker irregular broad lateral border and 

 large trapezoidal median blotch (sternal marking showing 

 through) limited to metathorax; a distinct paler-colored 

 sutural line between meso- and metathorax, with slight 

 angular emargination on the sides; mesothorax with a 

 paler-colored narrow median line separating the dark 

 quadrangular lateral blotches. Sternal markings consist- 

 ing of a median irregularly octagonal blotch on prothorax, 

 behind it a Y-shaped line running across mesothorax and 

 connecting with a large pentagonal metathoracic blotch 

 with apex directed anteriorly; in addition broad lateral 

 and coxal borders. Legs long, fore femora greatly thick- 

 ened, middle femora not so much so and hind femora 

 but little thickened; with scattered prominent hairs; con- 

 colorous with body. 



Abdomen, very large, elongate oval, with one long hair 

 in posterior angles of segments and several short ones 

 along sides and in angles ; a series of about twenty pus- 

 tulated hairs along posterior margin of segments 1-7; 

 these series extending laterally only to a pale-colored lon- 

 gitudinal line running parallel with the lateral margin of 

 body and about .16 mm. from it. Color dark brown, 

 with narrow black lateral border interrupted by sutures; 

 and extending in on each segment along posterior margins
