is visible without the use of a lens, by means of 
which, however, it is seen that the punctures of the 
type are present, only with the appearance of having 
been very nearly obliterated. The mandibles vary 
in color to pitchy and even red. The yellow spot 
behind the base of the antennse is generally absent. 
The post scutellum is occasionally spotted with 
yellow. One or other, or both, of the yellow rings on 
the hind body may be extremely indistinct or want- 
ing. The length varies from 12 to 16 mm. The 
female does not noticeably differ from the male 
except by the usual sexual characters. 
The distinctive features of the species are its whitish 
pubescence and the extremely strong emargination 
of the apex of the clypeus, the edges of the emargina- 
tion being more or less strongly produced forwards 
in an almost cylindric shape. 
35.— Odynekus insulicola. 
0. insulicola, sp. nov. Suhnitidus ; pubescens ; minus 
crehre punctatus; niger, fiavonotcdus, alis suhhyalinis 
obscure cceruleo-iridescentibus ; clypco antice emarginato ; 
abdominis segmento basali transverso antice verticali. 
Long. 9 — 11 mm. 
The punctuation of the head and thorax is rather deep 
but not coarse, and is somewhat sparsely distributed, 
becoming even more sparing on the scutellum and 
post scutellum. The metathorax is feebly rugose. 
Of the hind body the basal segment is strongly and 
moderately closely punctate, while the punctures of 
the second segment are fine, becoming coarser towards 
the apex, and the punctuation so continues on the 
other segments. The tibiae and tarsi are much clothed 
with ashy pubescence, and there is a good deal of 
whitish pubescence on the body,
