Jan., 1921] Hemiptera of the Family Miridce 109 



Venter: Brownish black to black; genital claspers distinctive of the 

 species (Fig. 0). 



9. Length 4.G mm., width 1.0 mm.; ovate, more robust than the 

 male ; membrane scarcely extending beyond the tip of the venter ; more 

 broadly pale on disk of pronotum and the base of the corium, also pale 

 along the front margin of the eyes; antennas dark brownish; legs 

 brownish, slightly tinged with greenish; venter slightly pale at the base 

 of the ovipositor. 



Holotype: cf Aug. 10, 1917, Katmai, Alaska (Jas. S. Hine) ; 

 Ohio State University Collection. Allotype: same data as the 

 type. Paratypes : 3 cf 4 9 taken with the types. 



Lygus pratensis oblineatus (Say). 



1832 Capsiis ohlineahis Say, Heterop. Hemip. N. Amer., p. 21. 



1857 Capsus oblineatus Say, Fitch reprint, Trans. N. Y. State Agr. Soc, XVII, 



p. 784. 

 1859 Capsus oblineatus Say, Le Conte edition. Compl. Writ., I, p. 340. 

 1917 Lygus pratensis oblineatus ICnight, Bui. 391, N. Y. (Cornell) Agr. Exp. Sta., 



p. 562. 



Five specimens of var. ohlineatiis (Say) were taken Aug. 

 16-20, Katmai. Heidemann (1900) records pratensis from 

 Alaska, specimens which were probably similar to the above 

 named variety. 



Plesiocoris rugicollis (Fallen). 



1829 Phytocoris rugicollis Fallen, Hemip. Suecia, p. 79. 



1861 Plesiocoris rugicollis Fieber, Eur. Hemip., p. 272. 



1896 Plesiocoris rugicollis Reuter, Hem. Gymn. Eur., V, p. 70. 



1909 Plesiocoris rugicollis Oshanin, Verz. Palce. Hemip., I, p. 733. 



30 d' 9 Aug. 2-15, 1917, Katmai; cf July, Savonoski, 

 Naknek Lake. This species has not previously been known from 

 North America. It is' recorded from Siberia and Russia by 

 Oshanin (1909) and is well known in northern Europe and 

 Scandinavia. The writer has compared the present material 

 with European specimens of rugicollis (Fallen), determined by 

 Reuter, and finds them identical. Reuter (1896) records the 

 species as occurring on Salix and rare on Alnus. The present 

 record completes the link in the holarctic distribution of the 

 species.
