189 
anterior tentorial pits, 1.8 as wide at level of antennal sockets as 
at anterior tentorial pits; with large, strong, mostly adjacent or 
subadjacent to a little sparser punctures. Clypeus: on each side 
subapically with a broad, weakly defined swelling. Temple: mod- 
erately receding behind eye; at its upper 1/4 about 0.56 as long as 
eye in lateral view. Pronotum: with a broad and foveolate dorsal 
submarginal groove; its lateral surface smooth and polished for 
some distance behind epomia but with coarse longitudinal wrinkles 
toward hind margin. Mesoscutum: notauli strong, apically con- 
fluent, reaching about 9/10 the length of mesoscutum; surface 
throughout with strong, subadjacent to a little sparser punctures. 
Mesopleuron: on most of its dorsal 1 / 3 with strong longitudinal 
wrinkling but on ventral 2/3 generally smooth and polished with 
numerous well spaced small punctures that become progressively 
denser rearward. Metapleuron: with strong reticulate wrinkling 
like that of propodeum; submetapleural carina low, defined only 
on about basal 2/3. First gastric tergite: 8.2 as long as wide at apex. 
Ovipositor: sheathed portion 0.6 as long as apical depth of gaster. 
Male: differs from female as follows: Color: scape entirely black; 
no yellow on frontal orbit; yellow on temporal orbit limited to a 
short line near mid-height of eye; scutellum entirely black; tegula 
entirely black; second gastric segment almost entirely black; and 
succeeding gastric segments darker than in female, blackish dor- 
sad and becoming dull yellowish brown ventrad; front femur 
rather dark brown below and posterio-dorsally on apical 3/4 and 
with yellow staining longitudinally between the dark zones; fore 
tarsus with weak brown staining on fourth segment and dark 
brown only on fifth; mid femur uniformly black on a little more 
than apical half; mid tibia dark brown on basal 1/8 and again on 
apical 1/3; about apical 1/3 of mid basitarsus dark brown; hind 
femur with dull yellow to piceous below on basal 1/2, which is 
brightest close to base and again on a fairly broad, dorsally pro- 
longed area just before mid length. 
Length of fore wing: 1 A mm. Flagellum: first segment 4.7 as 
long as deep at apex, second segment 2.3 as long as deep at apex. 
Face: 1.6 as high as wide at anterior tentorial pits, 1.4 as wide at 
level of antennal sockets as at anterior tentorial pits. Clypeus: 
subapical lateral swellings more strongly defined than in female 
and occupying all but median 1/4, which is depressed between
