frons and face meeting in slightly more than a right angle, the face some- 
what shorter than the frontovertex; as seen from in front, distinctly wider 
than long, but not greatly so, the sides of the head rounded, the oral 
margin rather broad,and subtruncate. Frontovertex about twice as long 
as wide, the orbits parallel; ocelli in a right-angled triangle, the anterior 
ocellus placed at the posterior third of the frontovertex, the posterior pair 
about their own diameter from the occipital margin and much closer to 
the eye margin; eyes rather smaller than in notativentris, somewhat less 
than twice as long as wide, widest near the anterior end; cheeks distinctly 
shorter than the width of the eyes; face with a rather shallow, semi-oval 
scrobal impression, the sides of the impression sloping; the bottom largely 
filled by the prominence between the antennae, which is about one-half 
longer than wide and reaches upward to the ocular line; the scrobes 
proper occupy the rather narrow space between the sides of the impression 
and the prominence, and converge and unite above in a curve. Antennae 
(Fig. la), inserted as usual close to the oral margin and far apart, more 
strongly clavate than in other species; scape rather wide, pedicel almost 
as long as the funicle and considerably narrower at apex than the scape; 
funicle joints all transverse and increasing in width, the fifth joint about 
twice as long and twice as wide as the first; club broadly oval, somewhat 
obliquely truneate at apex and as long as the funicle and two-thirds of 
the pedicel combined. Mandibles (Fig. 1b and ¢) of the usual type, with 
the outer tooth far basad, and the middle tooth considerably larger than 
the inner tooth. 
Thorax and abdomen normal for the genus, the ovipositor sheaths pro- 
truded for a distance about equal to one-fourth of the length of the abdo- 
men, or to the length of the middle tibial spur. Wings narrow, the disk 
finely, densely pubescent, but the setae in the basal area distinctly coarser 
and sparser; speculum narrow and only slightly widening as it approaches 
the posterior margin which it does not quite reach; stigmal vein narrow 
at base and gradually enlarging towards the apex, about twice as long as 
the marginal and postmarginal veins combined. 
Seulpture throughout very finely alutaceous, the frontovertex not per- 
ceptibly more granular than the rest of the body; both it and the meso- 
notum with very minute, scattered setiferous punctures. Pubescence on the 
head very short and inconspicuous, the setae on the frontovertex neverthe- 
less rather numerous and retrorse; eyes rather densely pubescent, the setae 
very short and erect; pubescence of mesonotum moderately thick and 
rather dark colored, quite uniform in distribution on the scutum, axillae, 
and seutellum. 
Color of head, thorax, and abdomen about eapucine yellow (Ridgway), 
the face and underparts of the thorax slightly paler with the scape, club 
and legs nearly unicolorous; remainder of antennae somewhat dusky; apex 
of ovipositor sheaths blackish; wings hyaline, the veins very pale brownish. 
Length of body (0.436 to) 0.721; length of head, 0.235; width of head, 
0.275; thickness of head fronto-oecipitally, 0.151; width of frontovertex,
