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, Cyon dukkhensis (Dhi- 
kala, Ghurwal District, at the base of the West Himalayas, 
India). This species is described by Piaget from a deer, Cer- 
vus porcinus, 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. (Pl. 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 thougli 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 similiar 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
