424 
from the same host collected at Sprecklesville, Maui, May 18, 
1921 (Swezey). 
25. Pteromalid undetermined. 
A single female collected in Olokele Canyon, Kauai, by Mr. 
Swezey, September 5, 1920, shows considerable affinity with both 
Bruchobius and Zatropis but at present remains unplaced. It 
is a comparatively robust species, with a lenticular head, the 
vertex being strongly declivous behind the ocelli. 
26. Pteromalus fuscitarsis Ashmead. 
Described from a single specimen taken on Lanai by Dr. 
Perkins in January, 1894, and not recognized by me. As 
there are no other species of Pteromalidae present in the Islands 
that can be considered endemic, I believe this species must also 
be an immigrant. 
27. *Pachycrepoideus dubius Ashmead. 
Two females were reared from puparia of the cane-borer 
Tachinid (Ceromasia sphenorphori Vill.) collected in Honolulu, 
April 10, 1911 (Swezey) and one female was obtained from 
a puparium of a Drosophila sp. in rotting pineapple collected 
in Honolulu, October, 1907 (Terry). Reintroduced by Fulla- 
way in 1914 from the Philippines. 
28. Pachyneuron allograptae Ashmead. 
Reared by Mr. Terry in April, 1904, from the puparia of 
Simosyrphus grandicornis (Maeq.), collected on the plantation 
of the Oahu Sugar Company. More recently a series was 
reared from sorghum heads collected in Honolulu, July, 1920 
(Timberlake), the host presumably being a Syrphid, as the 
material was infested with Aphis maidis Fitch. 
Previously recorded as P. syrphi (Ashmead), 1881, but that 
name is preoccupied by P. syrphi (Ratzeburg), 1848, which is 
the same as P. flavipes (Forster) according to Kurdumoff. 
P. allograptae Ashmead, 1887, is the next oldest available name 
for this common North American species.
