terior borders of the antennal fossae (about one-third the 
length of the head). Mandibles linear with a single acute 
terminal tooth, the outer border feebly convex, the inner 
border feebly sinuate. Antennal scapes short, strongly 
curved and very much enlarged toward the tips. The scape, 
which is approximately one-half the length of the head, is 
slightly more than one-third as long as the funiculus. First 
funicular joint notably smaller than the rest, slightly longer 
than broad ; second joint trapezoidal about as long as broad; 
the remaining joints all longer than broad, gradually in- 
creasing in length apically, the terminal joint bluntly 
pointed and slightly longer than the two preceding joints 
taken together. 
Thorax two and two-thirds times as long as broad, the 
dorsum entirely without sutures; pronotum from above 
subpentagonal, its posterior border marked by a prominent 
impression in the side of the thorax; mesonotum and epi- 
notum from above forming a single rectangular area having 
slightly rounded posterior angles and a small, rounded, 
median projection on the posterior face of the epinotum. 
Seen from the side the thorax is approximately four times 
as long as high, the pronotum evenly rounded in front and 
passing without transition to the flat mesonotum. Epinotum 
slightly higher than the mesonotum, the basal face moder- 
ately convex and passing to the short, abrupt declivious face 
through a broadly rounded angle. Petiole from above 
quadrate with the anterior edge perfectly straight, the an- 
terior angles broadly rounded. The anterior portion of the 
node has a virtually flat upper face but in the posterior 
half it is broadly and feebly concave. Seen from the side 
the node of the petiole has a straight upper border which 
passes to the vertical anterior face through a rounded angle 
and to the very short posterior face through a much sharper 
angle. Ventrally the petiole is constricted to form a very 
thick, short posterior peduncle and a much longer subtri- 
angular portion which extends forward under the node and 
is narrowed in front to form the anterior peduncle. 
Gaster slender, the first segment notably broader than 
long, segments two, three and four only slightly broader 
than long, the terminal segment somewhat longer than 
broad. Hypopygium deeply cleft in the middle, the lobes
