62 NORTH AMERICAN MALLOPHAGA 



skunks. It differs markedly from T. crassus in the much more rounded 

 temples of the male, and apparently is closest to T. mephitidis. It differs 

 trom the latter chiefly in being much larger, in having the anterior mar- 

 gin of the head much less rounded, and in the character of the genitalia 

 of the male. While it is rather peculiar to find the same species upon a 

 North American badger and a South American skunk, the specimens 

 from the two hosts agree in practically every detail. 



Description of the Female. — Total length 1.57 mm., length of 

 head, .425 mm., length of prothorax .11 mm., length of metathorax .09 

 mm., length of abdomen .95 mm., width of head across temple .675 mm., 

 width of prothorax .425 mm., width of metathorax .535 mm., width of 

 abdomen .9 mm. 



Head slightly wider than long and with the anterior margin but 

 slightly rounded, with a very shallow median notch, and produced into 

 prominent, trabecula-like process in front of each antenna. Antennal si- 

 nuses rather small and shallow. Ocular projections prominent, extending 

 well beyond the temples, which are rounded and meet the occipital mar- 

 gin with a slight angle. Occipital margin nearly straight, slightly emar- 

 ginate at the points where it is met by the occipital bands. Antennal 

 bands broad and very dark, separated from each other at the front of the 

 head by a very small clear space, and interrupted across the base of the 

 antennae, not reaching the ocular blotch. Occipital bands very short, 

 connected at their bases by a broad band. Anterior margin and temples 

 with several short hairs, the posterior margin with one long hair near the 

 temporal angle. Antennae rather small, not reaching the posterior mar- 

 gin of the head. First and third segments of nearly the same length, the 

 second segment a little shorter. 



Prothorax very short and broad, and with the posterior margin 

 slightly convex. A single short spine at each posterior lateral angle, and 

 one on each side of the meson on the posterior margin. Mesothorax a 

 trifle shorter than the prothorax and somewhat broader, the lateral mar- 

 gins curved and converging slightly, the posterior margin slightly con- 

 vex except for a slight median emargination. Lateral margin with three 

 or four short spines, posterior margin with a median group of eight 

 spines. Legs normal. 



Abdomen elliptical in shape, only a little longer than wide, and with 

 a narrow, hyaline band along the lateral margin. First segment with a 

 median group of eight or nine spines. Second to fourth segments each 

 with transverse row of spines divided into three distinct groups, the me- 

 dian group consisting of eight to twelve spines, and each lateral group of
