Deseription of a new species of Epeolus 
from Mexico. (Hym 
By. PS Cameron. 
Epeolus bifasciatus sp. nov. 9. 
Black, the lower inner orbits broadly, the face, labrum, 
and 2 spots on the Ist abdominal segment, on the sides 
above the apical slope, white; the apex of the 2nd 
abdominal segment and the 3rd to 5th abdominal segments, 
covered with fulvous yellow pubescence ; antennal pedicle 
reddish ; wings fulvous, paler, more hyaline towards the 
apex; the costa, stigma and nervures reddish fulvous. — 
Length 8 mm. 
The mesonotum is surrounded by a line of fulvous 
pubescence all round and there are 2 longitudinal patches 
on its basal half in the middle ; there is a narrower line 
on the apex of the scutellum. Metanotal area large, 
shining, closely, minutely shagreened ; its central furrow 
shallow, but distinct and irregularly crenulated; the 
metanotum is covered with short white pubescence, 
which gets longer on the outer edges. Front, vertex and 
mesopleurae closely and somewhat strongly punctured. 
Mesonotum shagreened. Scutellum widely, but not deeply 
furrowed down the middle. Pygidium shining, large, 
bare, the sides and apex stoutly keeled; it is almost 
bare, irregularly, weakly wrinkled ; its apex is broadly 
rounded. The hair on the legs is dense and silvery; 
on the underside of the tarsi (especially at the base) it 
is yellowish, more fulvous in colour. The abdominal 
segments become gradually narrowed from the base of 
the 3rd; jt is more pointed apically than usual. 
This species is a copy of Chartergus aztecus Cam., 
Odynerus nasidens Latr. and, I have seen a neotropical 
Gorytes of the same colouration. The resemblance to 
the Odynerus is further increased by the 2 marks on the 
base of the abdomen. It is most nearly related, apparently, 
to E. vagans Sm. The maxillary palpi I am unable to 
examine.
