GENOTYPES OF SOME ICHNEUMON-FLIES—CUSHMAN 287 
Genus TREVORIA Ashmead 
Trevoria ASHMEAD, Proc. U. S. Nat. Mus., vol. 23, p. 50, 1900. (Genotype, 
T. yukatatensis [sic] yakutatensis Ashmead.) 
The genotype was later described by Ashmead ® himself. It is 
represented only by the type male from Yakutat, Alaska. The mis- 
spelling of the specific name, which led Dalla Torre to record the 
species as from Yucatan, was corrected in the second reference. The 
genus appears to be most closely related to Cryptopimpla Taschen- 
berg, differing principally in the lack of the apical carina of the 
propodeum. The pentagonal areolet is only an exaggeration of a 
condition that sometimes occurs in Cryptopimpla. 
Genus PIMPLOPTERUS Ashmead 
Pimplopterus ASHMEAD, Proc. U. S. Nat. Mus., vol. 23, p. 52, 1900. (Genotype, 
P. alaskensis Ashmead. ) 
The genotype was redescribed by Ashmead.'? It is a Lissonota 
very closely allied to, and perhaps synonymous with, frigida (Cres- 
son), the most obvious difference being the largely black trochanters 
of alaskensis. 
(Pimplopterus Ashmead) =Lissonota Gravenhorst. New syn- 
onymy. 
(Pimplopterus alaskensis Ashmead) =Lissonota alaskensis (Ash- 
mead). New combination. 
The above new combination renders Lissonota alaskensis Ashmead 
(1902) a secondary homonym, which is disposed of as follows: 
(Lissonota alaskensis Ashmead, 1902, not [Pimplopterus| Lissonota 
alaskensis [Ashmead], 1900) =Lissonota sakala, new name. 
Genus HARRIMANIELLA Ashmead 
Harrimaniella ASHMEAD, Proc. U. S. Nat. Mus., vol. 23, p. 52, 1900. (Genotype, 
HA. yukakensis [sic] kukakensis Ashmead.) 
The genotype was redescribed by Ashmead" with the spelling of 
the specific name, derived from the type locality, Kukak Bay, 
Alaska, corrected. 
In my opinion the genus is not distinct from Lissonota. 
(Harrimaniella Ashmead) =Lissonota Gravenhorst. New syn- 
onymy. 
(Harrimaniclla kukakensis Ashmead)=Lissonota kukakensis 
Ashmead. New combination.
