ICHNEUMON-FLIES, PART 2'. EPHIALTINAE 371 



Colo., Aug. 12, 1948, H., G., and D. Townes; Poudre Lake, Rocky 

 Mountain National Park, 11,000 ft., Colo., two specimens Aug. 12, 

 1948, H., G., and D. Townes. 



Variation: The two specimens from Rampart House have the ventral 

 surface of hind tibia extending from pale basal area to the apex, 

 reddish; the front coxae and trochanters of all the specimens except 

 type and two of the three from Colorado (these two have them more or 

 less infuscate) are blackish; specimens vary from 7 mm. to 13 mm. in 

 length; ovipositor sheaths vary from little more than half (one speci- 

 men from Norman TVells, N. W. T.) to fully as long as abdomen. 



Two specimens from Alaska are placed here. One, from Naknek 

 River, while possessing the blackish palpi, tegulae, and longer ovi- 

 positor sheaths, has a definite white streak on the hind tibia. The 

 other, from Teller, Alaska, has the ovipositor barely one-half the 

 length of the abdomen. 



Host: Unknown. 



Either this species or novita (Cressor), or both, may prove to be 

 Delomerista mandibularis (Gravenhorst). 7 Certainly borealis is the 

 same as the specimens in the U. S. National Museum Collection 

 identified as mandibularis by A. Roman, and also the same as those 

 from G. Heinrich's collection and identified by him as mandibularis 

 (Gravenhorst). However, Gravenhorst's original description states 

 "postici tibiis basi summa fusca, annulo pallido, obsoletiore aut 

 distinctiore, ante basin, apice, vel latere toto supero usque ad annulum 

 pallidum, fusco, tarsis fuscis" which better describes the hind tibiae 

 of novita. Many of the species Gravenhorst placed in Pi?npla at that 

 time possessed hind tibiae with a central pale area which circled the 

 tibia completely, hence his stressing the fact that mandibularis had 

 the upper surface and sides fuscous. Because the type specimen is 

 unavailable to me and because Gravenhorst's description of the hind 

 legs of mandibularis better fits novita I have described this Nearctic 

 species as new. 



6. Delomerista pfankuchi (Brauns)

This species, belonging to the novita group, may not be present in 

 the Nearctic region. The single specimen before me is from the A. 

 D. Hopkins Collection and the label reads only "Accession No. 5928. 

 A. D. Hopkins, W. Va." Whether the specimen came to Dr. Hopkins 



1 Dr. Townes, who saw the 9 type specimen of D. mandibularis on a European trip (made since this MS. 

 was written), Informs me that the ovipositor has a strong dorsal curve apically. Therefore mandibularis 

 would fall in the jatonica group and may prove to be conspecific with japonica (= diprionis) as Uchida 

 suggested.
