228 ». CAMERON, HYMENOPTERA OF THE DUTCH EXPEDITION 
hyaline, the apical margin and the apex broadly fuscous 
violaceous; the nervures and stigma black. 9. : 
Front, vertex and thorax closely and strongly punctured, 
the punctuation on the median segment is stronger, the punc- 
tures being larger and more distinctly separated; the pubes- 
cence is close, short and pale; the sides of the segment are 
rounded. The post-scutellum has a straight oblique slope. 
Tegule black, brownish along the apex. Apex of clypeus 
transverse. Abdominal petiole long, curved, as long as the 
following segments united; it has the basal third slightly 
narrowed, the apex slightly dilated, not flattened above and 
bearing a short, distinct longitudinal furrow in the middle. 
The Qed segment is nearly twice longer than it is wide at 
the apex; its base is narrowed into a distinct neck. 
Eumenes insolens Smith from Gilolo (Proc. Linn. Soc. VIII, 88) 
is probably related to the species described above; it is smaller 
and wants the 2 conspicuous marks on the sides of the 2nd 
abdominal segment. In colouration dorycus agrees with E. 
pomiformis, but that species has the abdominal petiole shorter, - 
and, more particularly, it is widely dilated on the apical half 
and flattened above, not narrow, curved and cylindrical. Many 
of Smith's Malay species of Æumenes appear to have been 
fonnded on the slight varieties of the world-wide ranging 
E. pomiformis, e. g. inconspicuus, singularis, blandus, politus, 
architectus, agilis, vinder, floralis; and piriformis Sauss. and 
affinissimus Sauss. are other forms, as well as the American 
fraternus Say.

Icaria pruinosa sp. nov. 
Dark ferruginous, densely covered whith a white pile, which 
gives it a whitish appearance; black are: a broad transverse
