oval, about as long as the pedicel and funiele combined, and much wider 
than the last funicle joint. 
Mandibles narrow at apex, very unequally tridentate, the middle tooth 
much the longest, the inner tooth inserted much farther toward the base 
tlan the outer or ventral tooth; the base of the mandible rather wide 
and expanded in a plane at right angles with the plane of the apex. 
Palpi short, the maxillary pair with four joints, the two middle joints 
stoutest and only a little longer than thick, the basal joint nearly twice 
as long, and the apical joint about three times as long; labial pair with 
three joints, the middle joint hardly longer than wide, the apical joint 
about three times as long as thick, the basal joint a little shorter; labrum 
rather prominent, its apical margin transverse and ciliated with a row of 
fine hairs. 
Thorax very robust and of great depth dorso-ventrally, the mesonotum 
strongly convex; pronotum almost vertical, the collar very short; mesos- 
ecutum about twice as wide as long, its posterior margin trisinuate, the 
median lobe of the sinuosity much the widest and overlapping, when in 
normal position, the inner angles of the axillae; the latter, therefore, 
often appearing slightly separated but actually meeting; scutellum slightly 
longer than the mesoscutum, rather acute at apex, the dise somewhat 
depressed towards the base, more rounded towards the sides and apex, 
which are moderately elevated and abruptly declivous at the margins; 
propodeum short and nearly of equal length at the sides and middle. 
Wings of moderate size, the dise beyond the speculum densely ciliated; 
the costal cell nearly as densely ciliated; the basal part of dise more 
sparsely ciliated with longer setae, the row of setae guarding the proximal 
margin of the speculum much longer than the others; marginal fringe 
short throughout. Marginal vein between two and three times as long 
as thick; the stigmal rather long, or about thrice as long as the mar- 
ginal, nearly straight but with the apex curved slightly towards the 
costal margin; postmarginal vein nearly a half longer than the stigmal. 
Legs of about normal length and structure; middle tibiae somewhat 
enlarged at apex and with a row of about nine peg-shaped spines on 
the outer, apical margin, the spur stout and nearly as long as the first 
tarsal joint; middle tarsi rather stout and tapering to apex, the basal 
joint about equal to the next three joints combined, the plantar surface 
of the first four joints provided with numerous peg-shaped spines similar 
to those on the tarsi of Lupelmus; hind tibiae with two short unequal 
apical spurs; hind tarsi somewhat longer and slenderer than the middle 
pair, and without the conical spines on the plantar surface. 
Abdomen a little shorter than the thorax, triquetrous in shape, the 
apex bluntly rounded, the dorsal surface, when not distorted, much de- 
pressed and only slightly hollowed behind the first tergite, the venter 
moderately compressed, the ovipositor entirely enclosed by the ventrites; 
cerci or vibrissal plates situated on each side of the dorsum just before 
the middle, the vibrissae reaching nearly to the apex of the abdomen. 
Frontovertex with shallow, more or less confluent, thimble-like pune-
