280 Mr. P. Cameron on 
Parapsidal furrows distinct at the base. Pronotum tubercu- 
late near the base. Scutellum stoutly keeled on the basal 
half; the apical half with an oblique slope. Median segment 
with one central basal and two lateral ares. Spiracles 
elongate, narrow, rounded at the base and apex. Legs short, 
slender ; the base of the fore tibiw incised; the claws simple. 
Areolet five-angled, narrowed at the top ; the recurrent nervure 
is received shortly beyond the middle; the transverse median 
nervure is received in front of the transverse basal. Abdo- 
men very long, slender, almost cylindrical, nearly three times 
as long as the head and thorax united; the apex of the 
petiole dilated; the large spiracles placed at its base; there 
is a distinct ventral fold on segments 2, 3, and 4, a less distinct 
one on 5 and 6; the sheaths of the ovipositor project; there 
are seven dorsal segments. ‘The labrum is small and projects 
slightly. 
This genus belongs to the Oxypygi, as is shown by the 
presence of the ventral fold and by the pointed apex of the 
abdomen, It is easily distinguished from any of the known 
Joppina by the short dilated antenne and by the very long, 
narrow, almost cylindrical abdomen, tuberculated pronotum, 
and keeled scutellum. 
Leptojoppa erythrothoraz, sp. u. 
Capite nigro, albo-maculato; thorace, pedibus anterioribus, coxis 
trochanteribusque posticis rufis; antennis nigris, medio albo- 
annulato ; abdomine ceruleo ; alis fusco-hyalinis. 2. 
Long. 24 mm. 
Antenne thickened and compressed beyond the middle; 
the apex gradually and distinctly narrowed; the sides and 
lower part of the five or six joints beyond the middle white ; 
the scape finely and not very distinctly punctured, sparsely 
covered with short hair; a white somewhat conical mark in 
the middle at the base. The face and clypeus, the inner 
orbits (narrow below, wider above) to near the hinder ocelli, a 
somewhat triangular mark touching the eyes shortly behind 
the ocelli, a large mark on the lower orbits, narrow above, 
broad below, and reaching near to the base of the ocelli and 
the palpi, yellow. Face and clypeus strongly, uniformly, but 
not very closely punctured. Mandibles to near the teeth 
closely and rather strongly punctured; the two teeth very 
large, the upper much larger and more sharply pointed than 
the lower, which diverges downwards. Thorax rufo-ferru- 
ginous, except for a small yellow mark on either side of the 
pronotum and a slightly larger and longer one under the
