subtegular ridge, front and sides of mesoscutum connecting with long 

 stripes along the notauli, scutellum, front and middle legs, and first 

 five tergites except for their raised median areas, light yellowish 

 stramineous; flagellum light brown basally beneath; hind leg light 

 yellowish stramineous, the coxa brownish at base, the tibia brownish 

 apically and the tarsus entirely brownish. The extent of pale markings 

 varies considerably, and specimens from the far north may have the 

 thorax and abdomen almost entirely blackish and the hind coxa basally 

 blackish. The type of P. anomala is one of these dark-colored speci- 

 mens. The adult is figured by Howard in his description of P. dictynae. 



Howard (loc. cit.) describes the cocoon and a bit of the life history 

 of the type specimen. The larva was found May 15, 1887, attached 

 to the abdomen of a young Dictyna volupis. The spider was killed 

 by the larva, and cocoon spinning began on May 18. The larva 

 changed to a pupa on May 25 and emerged as an adult on June 1. 

 The cocoon of the type is lost. It is no longer with the type specimen. 



Specimens (7d\ 299): From Alaska (Mount McKinley at 2,000 

 and 2,500 ft. and Shaw Creek at Mile 289 on the Richardson Highway) ; 

 Arizona (Chiricahua Mts., Oak Creek Canyon, and Pocket Creek in 

 the Sierra Ancha); California (Davis); Colorado; Florida (Levy- 

 Warburg Lake in Alachua Co.) ; Illinois (White Heath) ; Maryland 

 (Cabin John and Takoma Park) ; Massachusetts (Waltham) ; Min- 

 nesota (Alexandria) ; New York (Johnsonville and Otsego Lake) ; 

 North Carolina (Mount Pisgah at 4,800 to 5,000 ft.); Nova Scotia 

 (Fountain Head) ; Ontario (Biscotasing, Gananoque, Ottawa, and 

 Point Alexander) ; Oregon (Hood River and McMinnville) ; Penn- 

 sylvania (near Pond of Woods at Presque Isle in Erie Co.) ; Washing- 

 ton (Mount Rainier at 2,700 ft.) ; Wisconsin (Nekoosa and Green 

 Lake Co.); and Mexico (Cuernavaca in Morelos). 



The collecting dates are from mid-spring to August 30, and one 

 specimen was taken September 6 at Johnsonville, N. Y. 



This species is Holarctic and widespread, but uncommon. In North 

 America it occurs from the Arctic to the subtropics. In the Old World 

 we have seen the type from Sweden and a specimen from Palestine. 

 Adults occur through most of the growing season.
