The first two costal cells are yellow brown 
and are densely covered with microtrichia. 
The brown costal band is very broad through- 
out its length ; it extends through most of cell R5 
(Fig. lb). No brown fumosity is present in 
the cubital area. The narrowed portion of the 
cubital cell is about 1.66 as long as that por- 
tion from the apex of the cell to the wing 
margin. Abdomen: Strongly petiolate and typ- 
ical of the genus as we have defined it above. 
Chiefly reddish, slightly tinged with brown, 
marked with black only at the base of the 
fifth tergum and with a brown to black vitta 
extending longitudinally over the median por- 
tion of this segment. The apex of the second 
tergum has a moderately broad band of gray 
pubescence. The abdomen is strongly convex 
above and hollowed out below; the basal seg- 
ment of the ovipositor is almost completely 
hidden within this hollow. Ovipositor: Very 
short, when fully extended (Fig. le) it meas- 
ures approximately 3.67 mm. The basal seg- 
ment measures about 1.15 mm. long by 1.0 
mm. wide at its widest point. The spiracles 
are situated 0.25 mm. from the anterior lateral 
margins of the segment. The inversion mem- 
brane is 1.35 mm. long by 0.23 mm. wide 
at its widest point. The rasper extends to 
within 0.52 mm. of the base of the segment. 
The piercer is very strangely developed, dif- 
fering from any that we have studied in that 
the apical portion is flattened laterally. The 
apex is serrated, and no preapical setae are 
visible (Fig. Id). The piercer measures about 
1.17 mm. long by 0.13 mm. wide at its widest 
point. 
Length: Body, 8.0-10.0 mm.; wings, 7.0- 
7.5 mm. 
TYPE LOCALITY: Java. The type of vespoides 
was from Amboina. 
Type in the Universitetets Zoologiske Mu- 
seum, Kopenhagen. 
The female described here is labeled "Am- 
bon 2.08”; this is a different spelling for Am- 
boina, and the specimen was probably 
collected by F. Muir.

This species has been adequately described 
by Malloch (1939^.* 411), except for a few 
details, but has not been figured. It is ap- 
parently most closely related to Callantra so- 
lomonensis (Malloch) (1939^.' 236) but is 
distinguished by its predominantly black ab- 
domen and antennae and dark-colored legs; 
it also lacks the prominent hump on the fifth 
abdominal segment (Fig. 2c) which is char- 
acteristic of solomonensis (see Malloch loc. cit., 
238, fig. 2). His figure is of a female specimen, 
and the hump is even more pronounced in 
the male specimen which we have on hand. 
Malloch apparently had but one female 
specimen before him, and a few details can 
be clarified. He described the thorax as chiefly 
brownish black; in the large series at hand 
the mesonotum and scutellum are reddish, 
tinged with brown, blackened just before the 
scutellum and behind the humeri. The pleura 
are dark reddish brown to black except for 
the yellow hypopleura and the vertical stripe 
on the mesopleura. The metanotum is black 
except for the brownish-red median portion. 
The hind femora and tibiae are dark brown- 
ish, the others are rufous tinged with brown. 
The wings are as shown in Figure la. Ab- 
domen: The first tergum is brown to black 
with a narrow yellow band at the apex, the 
extreme lateral margins of the first segment 
are yellow. The second tergum is reddish 
tinged with black, slightly yellowish along 
the apical margin; this apical portion is cov- 
ered with fine gray pubescence. The remainder 
of the terga are black, except for the yellow 
apex of the fifth and a large yellow spot in 
the middle of the hind margin of the fourth 
tergum. The sterna each have a row of rather 
long black hairs along their apical margins. 
Ovipositor: The visible portion, beyond the
