rounded, eye prominent with an ocular blotch similar to those in 

 front, only smaller ; a minute hair on the eye with another close 

 behind it and five more occurring on the temples, being placed quite 

 regularly around to the prominent occipital blotches ; one rather long 

 heavy hair on the temple arising at the point where it meets the 

 prothorax ; occiput slightly sinuous, without marginal hairs. Antennae 

 quite long, the terminal segment longest. (Fig. la). General color 

 of head and thorax pale yellowish brown. 



Prothorax short, slightly darker than head with divergent sides 

 and posterior margin convex; a minute hair on each lateral margin 

 and two longer ones on the posterior margin, one on each side of th 

 meson. Metathorax also short but considerably wider than pro- 

 thorax; a rather prominent hair on the acute anterior angle and two 

 similar ones behind, on the surface; sides strongly convergent, with 

 obtuse posterior angles ; posterior margin concave, without hairs. 

 Legs short, rather heavy with prominent claw and numerous hairs. 



Abdomen elliptical, slightly narrowed posteriorly; color pale to 

 transparent. Two hairs near the meson on each segment and two 

 others on each side midway between the meson and lateral margin; 

 several hairs in each posterior lateral angle. Margin thickened with 

 a continuous transparent band, enlarged at the sutures. Last segment 

 notched, with three hairs on each angle. Prominent spiracles on the 



lateral margins of segments 2, 3 and 4.

Trichodectes minutus n. sp. (PI. XX, Fig. 4). 

 Three specimens, one male and two females, from a weasel 

 (Putoris noveboracensis} were collected by H. E. Ewing 

 (Marshall, 111.). This species resembles Nitzsch's T. retusus 

 from Must el a vulgaris and M. ermlnea, but, unlike that species, 

 there is a striking difference in the antennae of the two sexes. 

 Osborn has recorded T. retusus from a weasel (Ames, Iowa). 



Description of Male: Color pale yellow. Head sub-pentagonal, 

 front angular, rather deeply incised with a clear space behind the 

 incision; prominent, trabeculae-like processes in front of the antennae; 

 antennal bands prominent, extending to the frontal incision where 

 they turn back, forming an acute angle. Antennae large, reaching 

 posteriorly beyond the head; first segment large and nearly as long 

 as the following two, of which the last is a little longer; several 

 short thick spines on the tip of the distal segment (Fig. 4c). Tem- 

 ples prominent, broadly, not angularly rounded as in T. retusus, with
