DESCRIPTIONS OF NEW SPECIES, AND DETERMINATIONS 

 OF OLD SPECIES OF ANOPLURA 



Family PEDICULIDAE 



Pediculidae Leach, Zool. Misc., vol. 3, p. 64, (1817). 

 Pediculidae Enderlein, Zool. Anzeiger, vol. 28, p. 136, (1904). 



Body depressed. Head not anteriorly produced into a cylindrical 

 process. Antennae three- or five-segmented. Eyes large and clearly 

 pigmented. Legs fitted for clasping. 



This family includes the Anopluran parasites of man and the mon- 

 keys, and at present numbers about a dozen species, of which but three — 

 and these the forms infesting man — have as yet been reported from North 

 America. An examination of the monkeys in our zoological gardens 

 would undoubtedly reveal some of the others. 



The man-infesting species, Pediculus capitis (De Geer), P. corporis 

 (De Geer), and Phthirius pubis (Linne), are too well known to require 

 discussion here. For a special discussion of the host-distribution of the 

 Pediculidae see Kellogg, "Ectoparasites of the Monkeys, Apes and Man," 

 in Science, n. s. vol. 38, pp. 601-602, October 1903. 



Family HAEMATOPINIDAE Enderlein. 

 Haematopinidae Enderlein, Zool. Anz., vol. 28, pp. 136, 137, (1904). 



Body depressed. Head not anteriorly produced into a cylindrical 

 process. Antennae three- or five-segmented. Eyes either entirely lack- 

 ing or very rudimentary. Legs fitted for clasping, the tibiae having a 

 thumblike process which opposes the claw. 



This is by far the largest family of the sub-order, including more 

 than three-fourths of all the species described. 



Genus HAEMATOPINUS Leach. 



Haematopinus Leach, Zool. Misc., vol. 3, pp. 64-65, pi. 146, (1817). 

 Haematopinus Enderlein, Zool. Anz., vol. 28, p. 138, (1904). 



Head very broad posteriorly, the temporal angles very prominent, 

 sharp and pointing forward. Antennae five-segmented. Thorax broad,
