NEW HYMENOPTERA FROM CEYLON. 145 
margin, broadened posteriorly, the sides slightly concave and 
crenulate, about one-third longer than the breadth on the posterior 
margin, vertically truncate posteriorly, the surface of the truncation 
shining, with a few indistinct longitudinal striz, the margin above 
the truncation pectinate, the four teeth near the middle long, the 
others scarcely developed. 
Black ; the thorax ferruginous ; legs, scape, and base of the flagel- 
lum fusco-ferruginous; second abdominal segment with a small 
round spot of white pubescence near the middle on each side, third 
and fourth segments with a transverse band of white pubescence 
at the apex; pygidium dark fusco-ferruginous. Ventral segments 
with a sparse apical fringe of long whitish hairs. 
Length, 4 to 5 mm. 
Hab.—Hambantota, Ceylon (Fletcher) ; November to February. 
Very similar to recondita, Cam., but differs in the sculpture of the 
pygidium and in the presence of teeth on the posterior margin of 
the thorax. 
Mutilla porcella, sp. nov. 
2 #F erruginea, rugosa, thorace arcuato, postice truncato, sex 
dentato, abdomine nigro, tertio segmento albopiloso. 
Head and thorax rugose, the posterior truncation of the thorax 
coarsely longitudinally striated, abdomen finely punctured, the 
second ventral segment strongly punctured, the second dorsal 
segment longitudinally rugose-striate. Head scarcely broader than 
the thorax, not rounded behind the eyes, the posterior margin 
straight ; eyes oval, as near to the base of the mandibles as to the 
posterior margin of the head. Scape finely punctured, the antennze 
not very stout, the second joint of the flagellum twice as long as the 
third, which is as broad as long. Thorax arched from the base to 
the apex, moderately convex, the anterior and posterior margins 
both very broadly rounded, more than half as long again as broad, 
the sides nearly parallel, shightly broadened on the median segment, 
the scutellar tubercle distinct but small, the posterior margin with 
six well-defined teeth, the two median the longest, the posterior 
truncation almost vertical. Pleura smooth and shining, very 
slightly concave. Abdomen convex, the first segment much 
narrower than the second, the pygidial area much longer than broad, 
very narrowly truncate at the apex and finely punctured. Tibiz 
with three or four well-developed spines on the outer margin. _ 
Ferruginous; the abdomen black; the third segment and the 
ventral segments at the apex clothed with long whitish pubescence ; 
calcaria white ; flagellum fuscous. 
Length, 6 mm. 
Hab.—Hambantota, Ceylon (Fletcher); November. 
Kasily distinguished from pinguicula, which is very similar in 
size, colour, and sculpture, by the teeth on the apex of the median 
segment.
