tion from the black band on the third tergum 
to the apex of segment five. The extreme 
lateral margins of the terga are extensively 
blackened. Ovipositor: Long and conspicuous; 
the exposed basal portion {in situ) is equal in 
length to segments four and five. The ex- 
tended ovipositor (Fig. 29e) is very elongate, 
measuring 8.32 mm. The piercer is 2.78 mm. 
by 0.21 mm. The apical portion is trilobate 
and has two pairs of strong bristles and two 
pairs of weak setae (Fig. 29d) situated ap- 
proximately 0.05 mm. from the apex. The 
opening of the oviduct is 0.26 mm. from the 
apex. The inversion membrane is approxi- 
mately 3.0 mm. long by 0.4 mm. wide at its 
widest point, the rasper extends to within 
about 1.4 mm. of the base of the segment. 
The basal segment of the ovipositor is 2.5 
mm. by 1.2 mm., measured across the prox- 
imal margin of the segment. The spiracles 
are situated about 0.47 mm. from the base 
of the segment, measured on the lateral 
margins. 
Length: Body, excluding ovipositor, 8.0- 
9.5 mm.; wings, 7. 7-8. 5 mm. 
MALE. Fitting the description of the female 
in most details; the narrowed portion of the. 
cubital cell is about twice as long as the dis- 
tance beyond the apex to the wing margin, 
and a well-developed supernumerary lobe is 
present.

This is a well-defined genus readily dis- 
tinguished from other Dacinae by the follow- 
ing characteristics: The presence of a trans- 
verse furrow or depression across the meso- 
notum, connecting the lateral sutures; a dis- 
tinct transverse furrow across the middle of 
the face; the lack of inner orbital, postocellar, 
postvertical, or ocellar bristles; the lack of a 
line of demarcation around the sides and hind 
margins of the humeri; the lack of inner 
scapular bristles; the presence of a pair of 
stout spines near the apices of the front fem- 
ora, below; the rather pointed scutellum; 
the elongate stigma or third costal section of 
the wing and the very short fourth section; 
the strongly incurved basal section of vein 
Mi-i-2, which greatly narrows the basal three 
fourths of cell 1st M 2 (Fig. 30^) and the 
abbreviated vein Cuid-lst A. 
The genus is related to Callantra by the 
elongate antennae (Fig. 30^) and the petiolate 
abdomen. Other workers have considered the 
mesonotal suture as being complete; we have 
found the suture to be interrupted in the me- 
dian portion of the mesonotum (in all the 
specimens examined); the lateral sutures are 
connected by a transverse depression. The 
genus contains but one known species.

A large, very conspicuous species, easily 
recognized by the generic characters given 
above. The following characteristics are sup- 
plemental to those which have been given 
under the generic discussion,
