The Hymenoptera of the Georgetown Musewm. 415 
Ephuta ? caenodonta, sp. n. 
Black, the centre and sides of front, vertex, antennal tubercles, the upper 
part-of the thorax, the upper half of the propleure and the upper part of the 
meso and metapleure more nairowly, a wide, interrupted line, narrowed 
on the apical outerside, and margined with rufous, on the apex of the 2nd 
abdominal segment. Head, thorax and abdomen not very thickly covered 
with longish white hair. There are 2 pale testaceous rounded tubercles on the 
top of the sides of the metanotum and 4 large testaceous spines below these. 
There are 6 irregular tubercwlar-like teeth on the sides of the back of 2nd 
abdominal segment, which is depressed between them. Pygidium covered with 
long, stiff black hair, smooth down the centre. The ventral keel is narrowed 
towards the base. Underside ot flagellum of antennee brownish red. Hyes 
prominent. Temples straight. obliquely narrowed behind them ; the occiput 
transverse. The Ist abdominal segment 1s short, gradually widened towards 
the apex. The apical third of the thorax is of equal width, bebind this it is 
rounded inwardly, the apex becomes gradually narrowed. The 3rd antennal 
joint !s one-half longer than 4th. Tibial and tarsal spines and the spurs white ; 
the hair on the legs long and white. Female. 
Length 6 m.m. 
Characteristic of this species are the tubercles on the sides of the 2nd 
abdominal segment. The generic position of the species 1s very doubtful. It 
seems, in some respects, to be intermediate between the Lphutind and the 
Sphaerophthalmi as defined by Ashmead (Canad. Ent. xxxiv., 6). The eves are 
prominent, hemispherical, smooth above, finely facetted below ; on the mandi- 
bles there is a small tooth at some distance from the apex. In Ashmead’s 
table (l.c. p.9) it runs to Dasymutilla, the type of which is Waco, Blake. That 
species has not the thorax spinose, nor has it tubercles on the 2nd abdominal 
segment. The Georgetown species may form the type of a new genus or sub 
genus. 
Traumatomutilla indica, L. 
diadema ¥. 
Two females of this species were given me by the Rev. Mr. Harper, both taken 
at Georgetown. The colour of the 4 spots on the 2nd abdominal segment 
varies from cream colour to reddish brown. The species is a Trawmatomutilla- 
Sphaeropthalma, Ashmead. 
Traumatomutilla nitidipustulata sp. n. 
Black, a broad curved line of white pubescence across the vertex, extending 
to the middle of the eyes, narrowed in the centre, a line on the sides of the 
apical slope of the metanotum, narrowed above and below on the inner side ; 
the apex of propleure, the apical third of the lower part of the mesopleure and 
of the metapleure, the sides of the 1st abdominal segment, spots on the centre 
of the 3rd to 5th, the spots becoming gradually larger, the sides of the 2nd to 6th 
segments and the apices of the ventral covere | with silvery white hair ; there 
ave 2 smooth, bare cream coloured spots on the base and apex of the 2nd seg-
