On the Hymenoptera of the Georgetown Museum. 155 
apical slope straight, oblique transverse. Pleure irregularly punctate, the 
punctures almost hid by longish white pubescence. Abdominal petiole strongly, 
irregularly punctured. Hind cox about two-and-a-half times longer than wide, 
densely covered with white longish pubescence. The abdominal petiole 
is not one quarter longer than the distance between its origin and the scutellum. 
Tn the Bradley table (/.c.) this species comes near E. pulcherrima, Szép. and 
longitarsis, Kief. 
Semeomyia quyanensis, sp.n. 
Black, the antennal scape and the basal two joints of the flagellum rufous, the 
former brighter in tint, the basal half of the mandibles of a darker red colour ; 
legs black, the anterior, the middle trochanters and knees testaceous, as is also 
the base of the hind trochanters ; wings hyaline, the nervures black ; metaster- 
nal process short, not forked ; calcaria pale, the longer of the hinder one-third of 
the length of the metatarsus. Hind ocelli separated from each other by almost 
double the distance they are from the eyes. Male. 
Length 4 m.m. 
Antenne stout, thickened towards the apex, the pedicle twice longer than 
wide, the third joint a little longer thanthefourth. Malar space not much longer 
than the antennal pedicle. Front and vertex closely, distinctly, but not very 
strongly punctured. Temples short, the occiput transverse. Mesonotum and 
scutellum smooth and shining, the furrows wide, deep, smooth. Metanotum close- 
ly reticulated, the base above in front of the abdomen with a semi-circular area, 
opaque, aciculated ; the part at its apex shining, smooth ; the top of the apical 
slope is more oblique than the lower and larger part. Abdominal petiole smooth, 
shining, except for an opaque line on the basal two-thirds; laterally it is deeply 
furrowed. The tibiz are shortly spinose, the hinder metatarsus as long as the 
other joints united. 
The genus Seme@omuia was described by Mr. J. Chester Bradley in the Trans. 
Am. Ent. Soc. xxxiv, including only Neotropical species, among others S. 
taschenbergi Brad. S. barticensis, Bradley and S. Kiefferi, Brad., from British 
Guiana. In Mr. Bradley’s table the species runs to oculata Szép. from Brazil 
and ablata, Schlett from Columbia.

Stenichneumon ? watertoni, sp.n. 
Black, the face, clypeus, mandibles, palpi, a narrow line of equal width on the 
inner orbits extending from near the ocelli to the antenne, a line of the same 
width on the top of the eyes, a wider one on the lower two-thirds of the outer 
orbits, its upper third obliquely roundly narrowed, a line on the sides of the 
pronotum, its base roundly narrowed to a fine point, its apex projecting 
down to the tubercles, two narrow lines near the apex of the mesonotum in the 
centre, the sides and apex of the scutellum, post-scutellum, the lower edge of the
