Clypeiis baud at apex of first, second, third and fourth dorsal abdominal 

 segments coucolorous or nearly with yellow marks on face. The second ventral 

 abdominal segment has a short yellow line on the apical margin of the segment 

 laterally, and the yellow band ou the fourth dorsal abdominal segment occupies 

 only about the middle third. 



The front of the scape, a spot on each side of the middle of the pronotum and 

 tlie lower edge of the tegulse are yellow, with a brownish cast. The posterior 

 aspect of the scape and the flagellum are chiefly dark brown. The latter, how- 

 ever, is reddish beneath. The sutures of the pleura and sternum are black. 

 The legs more of a testaceous ferruginous. The second dorsal segment with a 

 median lougitudin.il broad irregular dark brown band traversing the ferruginous

Type.— University of Kansas. 



Type locality. — Hamilton Co., 3350 ft., Kaus.'is. 



One male collected by F. H. Snow. 



Poli»»tes exclaiuaiis n. sp. 



15 mm. — Related to crinitiii:, but readily distinguished by the maculate pleura, 

 and by the immaculate dorsulum and by the brown spot on the clypeus. 



Clypeus a little longer than broad, obtusely augulate anteriorly, the angle being 

 somewhat rounded, with distinct scattered punctures on a roughened surface. 

 Ocelli forming an equilateral triangle, the distance between them approximately 

 three-fourths the distance between the lateral ocellus and the nearest eye mar- 

 gin. Anterior margin of the malar space approximately as long as the distance 

 between the lateral ocellus and the eye margin. Prothorax with a distinct mar- 

 gin anteriorly. 



Color. — Reddish brown, excepting in the following details: front, from the 

 middle of the emargination of the eyes to the clypeus with a yellow spot extend- 

 ing from either side of the insertion of the antennae to the eye margin, leaving 

 rather an oblong transverse brown spot between the base of tiie clypeus and the 

 insertion of the autennse. 



Clypeus yellow, excepting a rather large, median elongate spot which is brown. 



The ocellar region is black. 



A band from the base of the mandibles around the head. 



The mandibles, excepting the margins, which are blackish, the margins of the 

 prothorax, the greater part of the mesopleura, the tegulfe, excepting the margin, 

 which is testaceous, the scutellum anteriorly and the small segment to either 

 side of the scutellum anteriorly, the postscutellum, excepting the margins which 

 are blackish, two parallel lines on the posterior aspect of the metathorax. on 

 either side of the median sulcus extending nearly from the base to the apex, two 

 oblique bands on the metapleura separated by a narrow oblique black band, 

 oblique bands on the posterior aspect of the middle and posterior coxae, the fem- 

 ora at tip, the tibiai at base and the tarsi, the lateral and posterior margins of all 

 the abdominal segments, excepting the apical and the dorsal abdominal segment 

 are yellow. Anterior and middle tibia; on the inner and outer aspects are yel- 

 low, on the upper half of the mesopleura, the yellow maculation is in the form of 

 a rhomb and separated from the yellow maculation below. The anterior coxie
