 ples. 



Prothorax hexagonal, with anterior and posterior mar- 

 gins weakly concave ; in the obtuse lateral angles a hair 

 and two spines ; segment white witn a narrow submarginal 

 black band, the margin outside of it being more or less 

 suffused with smoky brown. Metathorax with a slight 

 lateral swelling on the lateral margin near the anterior 

 end, bearing a few short pale brown spines ; in the poste- 

 rior angles a single, longish, weak hair; segment white, 

 with a narrow, submarginal, lateral band, outside of which 

 on posterior half of segment the margin is smoky brown. 

 Sternal markings consisting of an intercoxal line, long 

 and curving forward, on metasternum, and two faint 

 median lines on presternum. Legs, white. 



Abdomen. Posterior angles with a single longish hair 

 and a shorter weaker one on lateral margin of each seg- 

 ment of segments 5-8; last segment flatly rounded with 

 two pairs of hairs, and the posterior fringe distinct; 

 dorsal surface without hairs, or with very few; segments 

 white, with broad, black, marginal, lateral bands fading- 

 out on eighth segment; indications of narrow, transverse, 

 linear, median blotches at the sutures; under side of

Var. pallidum Kellogg. Two females and a young 

 specimen taken from a yunco sp. (Lawrence, Kansas) 

 may be referred to this species but they show varietal 

 differences. The body color is pale golden, the mark- 

 ings are brown, not black, and the middle region of the 

 whole abdomen is pale brownish; of the head markings 

 only the ocular fleck and the bounding blotch on inner 

 rim of the antennal fossa are distinct.
