or three short hairs in posterior angles, segment 7 with 

 one hair in angle ; segment 8 much narrower than segment 

 7 and somewhat retracted into it; segment 9 hardly visi-

 segment 1 with complete transverse blotch deeply me- 

 dianly emarginated on its anterior margin; segments 2-7 

 with lateral, dark brown, transverse blotches separated by 

 the paler median third of the body surface and blunt 

 within ; each blotch with a distinct uncolored stigmatal

 extending entirely across segment; four longitudinal ro : ws 

 of weak nonpustulated hairs, two rows in median paler

Docophorus evagans n. sp. (Plate lxvi, fig. 2.) 



Taken from the Downy Woodpecker, Dryobates -pubes- 

 cent (Lawrence, Kansas). This Docophorus is a mem- 

 ber of Piaget's w r oodpecker infesting group angusttfrontes, 

 characterized by the anterior narrowing of the head with 

 small trabecular, and the elongate Nirmoid form of the 

 body. It departs from the more typical forms of the 

 group, however, in the relatively wide clypeal front. 



Description of male. Body, length 2 mm., width .62 

 mm. ; body color pale yellowish brown, with narrow dark 

 brown marginal markings. 



Head, length .53 mm., width .47 mm.; triangular but 

 relatively longer, and with wider frontal apex than in 

 other Do cop h or i of this group; two very short hairs in 

 anterior clypeal angles, one at suture and two in front of 

 trabecular; the trabecular are acute and reach to the end 

 of segment 1 of antennae; antennas slender; eye not 

 prominent, with a hair and small black fleck; temporal
