New genera and species of hymenoptera from India. 395 
dinally striated and rufous at the apex ; the ventral segments 
eoloured like the dorsal, | 
II. Joppini, 
3. Cosmiojoppa, gen. nov. 
Antennae compressed and dilated before the apex; in J' 
serrate. Seutellum roundly eonvex ; its sides not margined ; 
the post-scutellum not foveate at the base, Median segment 
regularly areolated, its base in the middle obliquely depressed ; 
the sides bluntly toothed ; the areola not raised, longer than 
broad and clearly defined. Wings uniformly fuscous-viola- 
ceous; the areolet 5-angled, narrowed above; there is no 
stump of a nervure on the eubital-discal nervure ; the trans- 
verse basal nervure is almost interstitial. Legs stout, the 
tarsi spinose; the apex of the hinder femora not exterding 
much beyond the 3rd abdominal segment, 
The face is flat: the ciypeus is not separated distinetly 
from it; the apex of the elypeus is transverse: the labrum 
is obliquely depressed. The head is well developed behind the 
eyes and is slihtly rounaly narrowed there; the occiput is 
roundly and deeply ineised. The areola is of variable form; 
it may be longer than broad, or broader than long; it is 
clearly defined all round and is widely separated from the 
base of the segment. The bodies of the species are black, 
largely marked with pale or orange yellow. The genus comes 
near to Ambiyjoppa, from which it may easily be separated 
by the convex seutellum and by the spined median segment, 
€. violaceipennis sp. nov. Z. Black, largely marked with

half of the mesopleurae, a small irregular mark on the apex 
above, and an irregular mark, incised at base on the meso- 
netum, yellow; the hinder femora black, broadly lived with 
yellow above. — Length 20—21 mm. 
Hab, Khasia Hills (Coll. Rothney). 
Scape of autennae yellow, black above ; the flagellum more 
or less brownish beneath, the middle with a yellow band. Head 
black, the face, elypeus, the inner orbits — more narrowly in 
the middle — the onter narrowly above. broadly below, the 
base of the mandibles and the palpi, yellow. Face and cly-
