NEW MALLOPHAGA. 473 



obtusely angled posterior margin, bearing on the mesal 

 third eight weak, non-pustulated hairs, and in the lateral 

 angles two longer and stronger hairs; large, transverse, 

 lateral blotches separated by a narrow, uncolored, mesal, 

 linear space widening anteriorly; legs pale brown, with 

 dark brown markings on dorsal margins of femora and 

 tibiae. 



Abdomen broadly elliptical, short, segments projecting 

 little or not at all at sides, and with two to three long 

 hairs in posterior angles; a single, transverse series of 

 hairs on dorsal surface of each segment; lateral trans- 

 verse blotches large, and with pointed inner ends; lateral 

 bands darker, not distinctly limited; posterior margin of 

 last segment flatly rounded, with numerous longish hairs 

 which are confined to the lateral portions of the margin. 



Female. Body, length 2.53 mm., width 1.04 mm.; 

 head, length .87 mm., width .87 mm.; the lateral abdom- 

 inal blotches much shorter, the hind body tapering poste- 

 riorly, and the ninth segment narrow, uncolored, tapering 

 behind, and narrowly angularly emarginated so as to

Docophorus alienus n. sp. (Plate lxv, fig. 2.) 



Found on a Yellow-shafted Flicker, Colaftcs auratus 

 (Lawrence, Kansas). This species does not resemble 

 any of Nitzsch's or Piaget's Docophori taken from wood- 

 peckers, but belongs to Piaget's group latifrontes, found 

 on the cuckoos. The group is characterized, according 

 to Piaget, by the width and emargination of the clypeus, 

 and by the large size of the posterior legs. The clypeal 

 characters are presented by this new form, but the pos- 

 terior legs are not especially enlarged. 



Description of the male. Body, length 1.62 mm., 

 width 7 mm.; the only specimen is a recently moulted
