562 Mr. Camerontrotes on Hymenoptera, 
tegule yellow; the teeth on femora are very strongly 
developed, especially at the apex. Length scarcely 
1} lin. 
Seemingly a variable species as regards coloration. 
One of my specimens has only the apex of the scutellum 
reddish ; another has it entirely of that colour, as well 
as the apex of the mesonotum. The colour of the legs 
also varies. 
Taken by Mr. Blackburn near Honolulu. (No. 56). 
Spalangia hirta, Haliday. 
Mr. Blackburn sends a specimen of this species, which 
was found by him in an outhouse attached to his resi- 
dence in Honolulu (No. 93). It is probably introduced, 
being a parasite of the house-fly. Walker (‘ Notes on 
Chalcidie,’ p. 88) records the other species (S. nigra) 
from the Galapagos Islands.

Crabro polynesialis, n. 8. 
Black; scape beneath and basal three-fourths of 
mandibles reddish-yellow ; calcaria testaceous ; labrum 
and cheeks covered with a dense golden pubescence ; 
head and thorax sparsely covered with longish hairs, 
fuscous on top, white at the sides; base of abdomen 
almost glabrous, the apical segments covered with longish 
silvery hairs. Head and thorax semi-opaque, finely 
punctured, the punctures on seutellum and post-scutellum 
rounded and more distinct than on the mesonotum, and 
very finely longitudinally striated; extreme base of 
metathorax longitudinally striated, and with a few short 
more or less indistinct carine running from the trans- 
verse ridge at the apex of the post-scutellum ; on the 
centre there is a furrow, which is scarcely visible on the 
upper half, but is more distinct on lower half. Abdomen 
smooth, shining, the apical segments faintly punctured 
and covered (especially at apex of segments) with white 
hairs; the last segment has two carine at the sides, 
which converge at the tip, which is acute. Wings sub- 
hyaline, with a distinct violet iridescence; nervures
