 anal scale large, not passing beyond ainil valves, pih)se. Kepugnato- 

 rial pore large, more deeply imj)ress«'d than in furci/er, placed near 

 transvj'rse suture, which is nearly straight.

 width, 2 to 2.")"'"'. 



This si)ecies (litters most strikingly from P. fnrcifer by having the 

 last segment produced considerably beyond anal valves, and also by 

 the idain color. In P.fnrvifer the last segnn'ut does not pass beyond 

 the anal valves, and the yellow lines and spots, which are absent in 

 zoitntUH and generally present in other species, are very bright; in fact, 

 much more than in any other species. 



The male genitalia, of which I have said nothing, dift'er very remark- 

 ably from that of P.furciferov P. oref/oniitftiit. 



I have examined two males of this species. They were collected by 

 Mr. (Jeorge (Jregg, of Chehalis, Wash. Terr.

 ninth pair with a cylindrical, tapering basal lobe, which is slightly tu- 

 berculate.
