June, 1907.] American Species of Papirius. 1 7 r 



Length 2-3 mm. "Habitat, Olympia, Washington." 

 Apparently MacGillvray is the sole collector of this species 



in America so far, at least we have no record given of it by any 



one else. 



8. Papirius purpurescens MacGillvray. 



1893. Papirius purpurescens MacGillvray. 



1895. Papirius purpurescens DallaTorre. 



Prevailing color, blackish purple. Head between the anten- 

 nae washed with yellow. Basal segment of the antennae very 

 short, one-third the length of the second; second segment white 

 or transparent. Body, dark purple; abdomen slightly hairy, 

 the hairs more abundant at the posterior end; last segment 

 fringed with clavate hairs. Legs long, slender, hairy. Claws 

 short, stout; superior claw with two teeth, one at the middle, 

 the other at the base ; inferior claw nearly as long as the superior, 

 more slender with two bristles at the tip; tenant hairs present. 

 Furcula dark purple, long, slightly hairy above; dentes half the 

 length the manubrium, narrowed beyond the base; mucrones 

 one-fourth the length the dentes; apex blunt, serrated at the 

 middle. Length 3 mm. Has been reported only from Long 

 Island. 



This is one of the largest species of Papirius, and has never 

 been reported except by MacGillvray.
