168 NYMENOPTERA FROM SARAWAK, 
The head is large and is well developed behind ae eyes ; 
the temples are broadly rounded ; the base of the thorax is round- 
ed, not transverse ; the sides of the median segment are round- 
ed, without any angles and the stigma is fulvous. 
This species has the colouration of O. hyades; that species 
may be known from it by the apex of the clypeus being trans- 
verse, by the temples not being rounded, by the base of the 
thorax being transverse and by the sides of the median seer 
projecting and its apex transverse. 
Odynerus hyades, Cam. 
This species (described Journ. Str. Br. R. A. Soc., 1902 
112), is variable as regards the amount of yellow on the body 
and of the black on the legs. ‘The pronotum is transverse, not 
rounded. 
Odynerus 7—fasciatus, Sm, 
This species has been taken at Matang, 3,600 feet and at 
sabras. It is easily known by the body being thickly covered 
with black erect hair, and by all the abdominal segments being 
banded with yellow. It is probably a variable species as regards 
the quantity of yellow on the head and thorax and also as re- 
gards the amount of black on the legs. ‘The 6 has the clypeus 
entirely yellow; not broadly marked with black in the centre as in- 
the @ ; it is also slightly roundly incised at the apex, not trans- 
verse as in the 2. Characteristic 1s the fact the first two trans- 
verse cubital nervures are almost united at the top. 
The species has a close resemblance in from and coloura- 
tion to a Vespa. It is probably of wide range in Malaya and has 
been recorded from Sumatra by Gribodi who describes it in full 
in Bull. Soc. Ent. Italiana, X XIII. 
Odynerus carinicollis, 8p. nov. 
Black; the prothorax red; the clypeus, except for a black 
transverse mark in the middle, the eye incision, a mark, roundly 
dilated at the apex on the lower part of the front, a line on the 
upper half of the eye orbits, the edge of the median segment and
