NEW HYMENOPTERA FROM CEYLON, 149 
striated, rounded at the apex. Eyes nearer to the posterior 
margin of the head than to the base of the mandibles. Head orbi- 
cular, no broader than the thorax, the second joint of the flagellum 
a little longer than the third. Thorax nearly twice as long as broad, 
very slightly rounded posteriorly, a little more strongly anteriorly, 
the sides almost parallel, very feebly emarginate, the posterior 
truncation almost vertical and coarsely rugose. Pleura concave, 
almost smooth, with a few fine and shallow punctures. Ventral 
abdominal segments very finely punctured, the second coarsely and 
closely punctured. Tibize with two rows of spines. 
Ferruginous ; antenne fuscous towards the apex ; legs rufotes 
taceous ; abdomen black, a spot of white pubescence on the apical 
margin of the second, fourth, and fifth segments ; calcaria whitish. 
Pubescence white on the sides and ventral surface, black on the 
dorsal surface of the abdomen, pale ferruginous on the head and 
thorax. 
Length, 6 mm. 
Hab.—Hambantota, Ceylon (Mletcher). 
This seems to be allied to nagrigena, André, and rufiventris, Sm., 
neither of which are known to me except by the descriptions.

I cannot see that these forms are distinct. Bingham’s distinctions 
between the two are not accurate ; Saussure distinctly says of 
hexaops “pedes ferruginei,’ and this corresponds with a specimen 
named by him in the British Museum collection, but Bingham says 
“legs black, antennz ferruginous.”’ The antennz in hexaops are 
fuscous, the scape fusco-ferruginous. 
6. Niger, abdomine rufo, segmento primo, apice excepto septimo- 
que nigris ; alis flavo-hyalinis, scutello tuberculato. 
Black; the pubescence gray ; segments 2 to 6 of the abdomen 
and the apex of the first ferruginous with light ferruginous 
pubescence. Wings hyaline, tinged with yellow, nervures pale 
testaceous. 
Clypeus shining in the middle and sparsely punctured, with a 
median carina, the sides covered with long pubescence. Antenne 
stout, the second joint of the flagellum scarcely longer than the 
third. Head closely punctured, thorax rugosely punctured, a 
shining median line on the anterior half of the mesonotum, the 
posterior half more coarsely sculptured, with a deep longitudinal 
sulcus on each side. Scutellum raised in the middle into a low 
shining tubercle, with a deep, shining transverse depression at the 
base. Pleura coarsely punctured, the metapleuree and median
