of the eye orbits, the mark incised in the middle, the upper projection the 
smaller, a narrow line on the upper fourth of the outer orbits, a broader line 
round the top of pronotum, a large conical mark on the base of propleure, 
a small curved spot, its lower part narrowed, on the upper basal part of meso- 
pleurz, the horny point behind the tegule, the depression at the sides of seu- 
tellum, post-scutellum, a small squarish spot on the base of metanotum at 
the sides, a large mark on the sides of the lower half, extending from the pleu- 
re onto the metanotum where its lower half is dilated and the apices of all the 
abdominal segments from the 2nd yellow ; the lines on the apical ones wider 
and more integular ; the line on the 2nd ventral clearly divided into 3, the 
central straight, wider than the lateral which are dilated on the outer side, 
the under side of the Ist abdominal segment, except for a triangular black 
mark at the base of the node, and a broad band above near the middle testa- 
ceous. Antenne black above, the basal third of the scape yellow, the rest 
rufous-testaceous. The apex of the femora, the tibie and the tarsi yellow. 
Wings hyaline, the radial cellule with the apical three-fourths smoky, the 
stigma and nervures black. Male. 
Length 7 mm. 
Thorax twice longer than wide, the base distinctly roundly narrowed. 
Metanotum short, the sides broadly rounded, the centre hardly depressed and 
with a narrow furrow of equal width throughout. Petiole, if anything, longer 
than the thorax ; the narrowed basal part slightly longer than the dilated apex, 
which becomes gradually widened ; above it is rounded gradually ; the basal 
part more oblique, less rounded than the apex. 2nd segment as long as it 18 
wide at the apex, the base narrowed roundly, the top obliquely roundly 
sloped. Clypeus as long as wide, aciculated, shining, the middle with scat- 
tered punctures, the apex depressed, the sides rounded, hardly forming teeth. 
Front and vertex closely and finely, the thorax more strongly punctured, the 
scutellum more strongly than the mesonotum, the metanotum, if anything, 
more strongly than the scutellum and with the punctures more widely separa- 
ted. Ocelli in a curve, the middle only slightly in front of the others. Apex 
of post-scutellum gradually narrowed tothe centre, the sides straight oblique. 
A distinct species, easily known by the roundly narrowed, not wide, trans- 
verse, base of thorax by the metanotum not being depressed in the middle 
with the depression widened at the apex and by the wide pale fulvous band on 
the petiole. The Ist recurrent nervure is interstitial as in Z. totanacus. Saus., 
but the scutellum is not “parted by a strong groove,” nor is the antennal hook 
“very small, ’’ but longish and stout; and the body is distinctly greyish, 
through the dense grey pile, which is not the case with otonacus, which has also 
the metanotal furrow of the usual form, ¢.e. widened below. 
Eumenes acapulcensis, sp. n. 
Black, densely covered with a white pile, which is, as usual longer and 
denser on the metanotum, 2 oblique spots on the top of the clypeus, a small one 
on the inner edge of the eye incision, a line on the top of basal slope of prono- 
tum extending on to both sides of the keel and dilated laterally, a line round
