Seulpture otherwise not differing materially from odyneri, and similar to 
the female. 
The suberect pubescence on frontovertex and upper part of face 
rather dense and long, or about as in odyneri; the tuft of fine pubescence 
on the pedicel confined to the apex on the dorso-anterior margin; the 
short, erect pubescence of eyes rather dense as in odyneri. 
Coloration as in the female except that the antennae are somewhat 
more brownish. 
Length of body, (1.09 to) 1.19; length of head, 0.487; width of 
head, 0.471; width of vertex at posterior ocelli, 0.223; width of mesos- 
eutum, 0.450; length of forewing, 0.992; width of forewing, 0.447 mm. 
Described from 76 females, 7 males (holotype, allotype and 
paratypes), reared July 22, 1920, from a larva of Odynerus 
nigripennis (Holmgren), collected on the ditch trail near 
Keanae, Maui (O. H. Swezey). 
Nesencyrtus kaalae (Ashmead). Figures 4, 5. 
This species seems to have been unusually common in the 
fall of 1919 and following winter, as large series were reared 
at that time from the larvae or pupae of Nesoprosopis fusci- 
pennis (Smith) and a small species which was probably N. koae 
Perkins, collected in the mountains back of Honolulu by 
Messrs. Bridwell and Williams. 
From a pupa of what was probably Nesoprosopis koae, col-

the Thurston trail, Nuuanu Valley, Oahu, on October 19, 1919, 
1 male and 17 females issued on November 1-2, and 5 living 
females were also taken in the debris of the same stump.
