Descriptions of New Genera and Species of Hawaiian 
Encyrtidae (Hymenoptera), III. 
BY P. H. TIMBERLAKE. 
(Presented at the meeting of December 1, 1921.) 
The present paper completes the consideration of Hawaiian 
Encyrtidae so far accumulated, except the endemic species of 
Anagyrus. The genera here treated all belong to the Mirini 
and the new species are apparently endemic. The types have 
been deposited in the collection of the Hawaiian Entomological 
Society. 
Coelopencyrtus Timberlake. 
The discovery of a fourth species of this interesting genus 
seems to indicate that our knowledge of its extent is far from 
complete. Of the described species three have been reared 
from Odynerus nigripennis (Holmgren) and only one from all 
the other species of Odynerus, although Dr. Perkins has re- 
corded one or two probably undescribed species from the larvae 
of Odynerus montanus Smith and O. oahuensis Dalla ‘Torre.* 
The preponderance of material reared from nigripennis is 
probably due to the fact that the nests of this species are much 
more frequently found than those of any other species of 
Odynerus, which are perhaps just as frequently parasitized. 
The females of Coelopencyrtus are not easily distinguished 
as a rule, whereas the males show good characters in the struc- 
ture of the head and antennae. The following table of the 
species may be found useful, although no characters have been 
discovered which will distinguish the females of odyneri and 
swezeyi in all cases. The distinctions given for these two 
species apply only to specimens from Oahu, as specimens of 
sweseyi from Hawaii have the characters, given for odyneri, 
except that the eyes are considerably more sparsely pubescent 
than in specimens of either species from Oahu. 
FEMALES. 
1. Head not greatly wider than long, if at all; the frontovertex nearly 
thrice as long as wide; the eyes distinctly pubescent............ 2
