332 PROCEEDINOS OF THE NATIONAL MUSEUM. vol.58. 



Academy of Natural Sciences of Philadelphia has been examined by 

 the writer. It is also larger than the type and differs also in having 

 the abdomen becoming nearly black at the apex, wings yellowish 

 hyaline, hairs of face longer and more yellowish, ovipositor slightly 

 less than hall as long as abdomen. According to Mr. Rohwer's 

 notes, the type male differs from the female but little be3^ond the more 

 reddish legs and the more hairy head and thorax. The only male 

 in the National Museum differs from the female in the same way and 

 also has the tegulae whitish basally. 



Other characters of the female worthy of mention are: Clypeus 

 broadly, rather deeply emarginate; malar space about three-quarters 

 as long as basal width of mandible; eyes broadly arcuate within; 

 face broader than vertex, the latter below level of top of eyes; diame- 

 ter of lateral ocellus nearly twice as great as ocellocular line and 

 nearly as long as postocellar line; lower margin of antennal foramina 

 below middle of eye; front deeply concave and transversely rugulose; 

 antennae nearly as long as body, very slender, not attenuate at apex ; 

 notauli briefly, rather deeply impressed; propodeum strongly trans- 

 versely rugose above, ruguloso-punctate laterally, polished behind, 

 spiracle long oval; dorsal carinae of first tergite obsolete, their posi- 

 tions occupied by broad polished areas. The types are from British 

 Columbia, where they were reared from Ellopia sommaria and the 

 National Museum specimens are from California, one female collected 

 by H. S. Barber in Humboldt County and the rest collected by 

 W. M. Mauer at Pacific Grove. 



EPfflALTES (EPHIALTES) SODALIS (Ruthe). 



Pimpla sodalis Ruthe, Stettin. Ent. Zeit., vol. 20, 1859, p. 371, female, male. 

 Pimpla nordenskioldi Holmgren, Oefvers. Svensk., Vet.-Akad. Forh., vol. 29,. 



pt. 6, 1872, p. 97, female. 

 Pimpla longiceps Thomson, Opiisc. Ent., pt. 8, 1877, p. 746, 1877, female, male. 



This species, with which Roman ^ sjnonjjmzesnordens'kioJdi Holm- 

 gren, has been recorded under the latter name from Greenland by 

 Holmgren in his original description and by Aurivillius ^. It dijBFers 

 from all the other North American species of Pimplidea in having the 

 coxae black and the legs otherwise mostly red, being allied in this 

 respect to instigator Fabricius of Europe. No specimens of the 

 species are available for exajnination. 



Distribution. — Northern Europe, Iceland, Greenland. 



EPHIALTES (EPHIALTES) LONGIGENALIS, new species. 



Apparently very closely related to sodalis (Ruthe), differing from 

 descriptions of that species only in having the hind tibiae and tarsi 

 entirely red. Because of this difference it runs in Schmiedeknecht's
