92 Psyche [June 
obtuse angles the posterior margin runs back and inward in a flatly curving line 
for about one third of the width of the segment, the middle third of the posterior 
being straight, with a shallow concavity. A series of fine but distinct short hairs 
in a series roughly parallel with the slightly concave but nearly straight third of 
the posterior margin of the metathorax. Straight diagonal bands of darker color 
showing through each thoracic segment from the underside. Legs conspicuously 
long, largely because of the unusual length of tibiz, tarsi and claws; tibie growing 
wider toward tip and bearing a short, strong, blunt, spineless projection at the inner 
angle of the tip; tarsi of middle and hind legs with claws of unusual length, each 
claw being longer than both tarsal segments together and more than half as long 
as the tibia; claws of the forelegs but a little more than half as long as those of mid- 
dle and hind legs, but more strongly chitinized. 
Abdomen, length .64 mm., width .60 mm.; almost roughly circular in outline, 
although really broader in front than behind, and with the projecting, tapering 
last segment and genitalia destroying the circular outline. Second segment with 
deeply but broadly emarginate posterior border. Lateral margins almost dentate 
because of the projecting posterc-lateral angles of each segment. Each segment 
bearing a series of many fine short hairs along the median two thirds of the pos- 
terior margin; longer but inconspicuous hairs projecting from the postero-lateral 
angles of the segments. Strongly colored, but narrow, lateral borders on all seg- 
ments; and conspicuous dark median transverse blotches covering most of the 
dorsum (for the middle half of its width) on segments three to six inclusive; last 
segment of abdomen narrow and projecting backward with the genitalia showing 
distinctly. 
Female: Body, length 1.57 mm.; head .46 mm., width .56 mm.; length of 
abdomen .88, width .69 mm., the abdomen thus being considerably longer than 
broad, and hence not of the nearly circular shape of that of the male. The antennz 
are not as long and slender as those of the male, the second segment being only 
slightly longer than the third. The ground color of the body and markings 
both paler than in the male, but the markings and blotches about the same in ar- 
rangement and character. 
The species name paine? is given for Mr. J. H. Paine, an active 
American student of the Mallophaga.
