Trichodectes parallelus Osborn. 

 Four specimens from the red deer (Michigan Agricultural 



College). 



Trichodectes subrostratus Nitzsch. 



Numerous specimens from a domestic cat (Stanford Uni- 

 versity), also collected in large numbers from a lynx, Lynx 

 rufus (San Gregorio, Cal.). It is not known whether the 

 species generally infests the lynx or not, but probably this is 

 a case of "straggling." 



Trichodectes forficula Piaget. 



Four specimens from a wild dog. Cyan dukkhensis (Dhi- 

 kala, Ghurwal District, at the base of the West Himalayas, 

 India). This species is described by Piaget from a deer, Cer- 

 vus porcinns, from the Zoological Gardens of Rotterdam. This 

 case is not so easily explained by "straggling."' 



Trichodectes climax Nitzsch. 

 Collected in large numbers from an Angora goat (Palo Alto, 



Cal.). 



Trichodectes scalaris Nitzsch. 



Found in large numbers on calves. 



Trichodectes parumpilosus Piaget. 

 Abundant on the horse. 



Trichodectes octomaculatus n. sp. (PI. XX, Fig. 1.). 

 A large number of specimens, apparently all female, from 

 the western raccoon, Procyon psora (Stanford University), 

 This form is easily recognizable by the eight distinct chestnut 

 blotches on the head, these being the only dark markings on 

 the insect. 



Description of female : Head broader than long with front broad- 

 ly rounded though slightly flattened on the sides, with a clear space 

 in the middle not excised; the antennal bands turn inward just as 

 they reach the central clear portion and end in a chestnut colored 

 blotch; there is a similar blotch on the margin well in front of the 

 small trabecuiar projections. There are several minute hairs on the 

 frontal margin, two on each side of the central clear portion, one 

 between the two blotches and another near the posterior frontal 

 blotch; also a still smaller one on the trabecular-like projection and 

 four on the dorsal surface, two of which occur close together just 

 behind the central clear portion while the others arise, one on each 

 side, near the margin close behind the posterior blotch. Temples
