broad, slightly convex space between the antennal sockets. Mandibles 
similar, but the two inner teeth are very short and subequal, and taken 
together they are deeply divided from the long, acute ventral tooth. 
Seutellum distinctly longer than in Hypergonatopus and more pointed 
at apex. Middle tarsi nearly of the same thickness from base to apex. 
Abdomen of the same size and shape, but the ovipositor issues from 
near the base of the venter. Sculpture of the same type as in Hyper- 
gonatopus, but the reticulations of the mesoscutum are very faint, and 
the seutellum is nearly smooth and not duller than the seutum. In other 
respects similar to species of Hypergonatopus.

Female. Frontovertex narrowest in front of the ocelli and_ slightly 
widening towards the occipital margin; ocelli in an acute-angled triangle, 
the distance between the posterior pair about a third less than the dis- 
tance from either to the anterior ocellus, the posterior pair about one- 
half their own diameter from the eye-margin and somewhat more than 
twice as far from the oecipital margin. Scape slender, reaching beyond 
the serobal impression, thickest at the middle, the ventral margin slightly 
arcuate; pedicel nearly three times as long as thick at apex and fully 
equal to the first three funicle joints combined; flagellum gradually in- 
ereasing in thickness distad; funicle joints all wider than long, the first 
four nearly equal in length, the first one but slightly wider than long,

the fourth about twice as wide as long, last two funicle joints about 
twice longer than those preceding, each about one-half wider again than 
long; club rather elongate oval in shape, somewhat obliquely truncate 
and acute at apex, and about equal in length to the funicle and one-half 
of the pedicel combined. 
Mesoscutum strongly transverse or nearly two and one-half times wider 
than long, its posterior margin straight; axillae about two and one-half 
times as wide as long, their inner tips very acute and nearly meeting; 
seutellum about one-half longer again than the seutum, rather strongly 
convex and declivous at the sides and apex. Forewing about 2.54 times 
longer than wide; the marginal vein elongate or about four times as
