broadly rounded, not separated from tbe face in the middle ; the sides 
above with a distinct fovea, from which runs below a narrow furrow. 
Eyes large, parallel; there is a short, but distinct, malar space. The hind 
metatarsus is more than one-third of the length of the tibiae ; the spurs 
of normal length ; the claws simple ; antennae shorter than the body. The 
scutellum is flat, or at least not much raised above the mesonotum, which 
has no indications of furrows. 
The affinities of this genus are clearly with Pimplamorpha , Cam. ; that 
genus may be known from it by the apex of the first abdominal segment 
not being swollen, but gradually dilated ; by the clypeus being more dis- 
tinctly separated from the face, by the recurrent nervure not being received 
clearly beyond the transverse cubital, by the apical longitudinal nervures 
in the hind wings being clearly traced and the transverse median distinctly 
broken ; the pterostigma is longer and not so thick in the middle ; the 
radial cellule is narrower, not so much widened in the middle, the scutellum 
is more convex, and the metanotum is less distinctly areolated, the basal 
areae, including the areola, being not clearly defined. 
The following table may aid in the determination of the species of 
Andrcma described here : — 
1 (4) Mesonotum for the greater part black. 
2 (3) Mesonotum with only two continuous yellow lines, the face 
and clypeus yellow. variventris. 
3 (2) Mesonotum with two lines and a large square mark in the 
centre of the apex, the face and clypeus broadly black in the 
middle. spilopus. 
4 (1) Mesonotum rufo- testaceous. 
5 (6) The black line on the metanotum extending from the base to 
the apex, the back of the basal two abdominal segments entirely 
black. flaviceps. 
6 (5) The black lines on the metanotum and the basal two 
abdominal segments not reaching to the apex. 
7 (10) The black on the metanotum not narrowed to a fine point, of 
equal width throughout. 
8 (9) The head for the greater part pale yellow, the mesosternum 
black, the black in centre of second abdominal segment wider 
than the outer testaceous part. latimaculata. 
9 (8) The head without yellow, the sternum immaculate, the black 
on second abdominal segment narrower than the outer tes- 
taceous part. fuscicornis. 
10 (11) The black on the metanotum narrowed to a fine point. 
basiornata. 
11 (10) The metathorax entirely black, the second abdominal segment 
lined laterally with black. flavo-orbitalis. 
Androna variventris, sp. n. 
Black ; the face except for a short black line below each antenna, 
the clypeus, mandibles except the teeth, the eye orbits except opposite 
the ocelli, antennal scape, a line down the sides of the mesonotum, com- 
mencing near the apex and continued to the base where it is dilated and
