scutellum is triangular, the basal and apical slopes being 
straight and oblique. Basal arez of median segment closely 
punctured, the middle obliquely, the apical more strongly 
transversely striated ; the areola is twice longer than broad ; 
the spines are sharply pointed, long ; the part outside them 
is coarsely striated ; the rest of the spiracular area is closely 
punctured. The second and third abdominal segments are 
minutely and closely punctured. Gastrocceli curved, deep, 
narrow. The sheaths of the ovipositor are distinctly longer 
than the last segment, which is longer than the penultimate. 
Acanthojoppa nigromaculata, sp. n. 
Luteous; the basal sixteen joints of the antenne more 
yellowish in tint towards the middle; the others infuscated. 
The inner and outer orbits broadly, the greater part of the 
clypeus, the mandibles, and the pleurz, pale yellow; the 
apex of the mesonotum, a mark longer than broad on 
the basal half of the scutellum, the base of the median 
segment all round, the posterior median area, a line below 
the tubercles and one over the hinder coxe, black; the four 
front coxee are of a paler yellow tint. Wings hyaline, the 
basal half has a fulvous tinge; the stigma testaceous, the 
nervures blackish.  ¢.

May be known by the small size of the areola; it is 
broader than long, rounded behind, and bears some stout 
central and a few oblique lateral keels. Face punctured, 
but not very closely ; the upper part of the clypeus sparsely 
punctured; both are covered with pale hair; the vertex is 
closely punctured and covered with shorter darker hair. 
Mesonotum coarsely shagreened ; the scutellum is closely 
and distinctly punctured above and thickly covered with 
blackish hair. Postscutellum smooth; the basal fovez 
deep and clearly defined. The base of the median segment 
is closely punctured; the posterior areola is rather small, 
broader than long, rounded behind, transverse at the apex ; 
the apical are are coarsely transversely striated ; the base 
of the spiracular closely punctured; the rest obliquely 
stoutly striated; the spines are longer than broad and 
gradually narrowed towards the apex. Propleure smooth, 
except for some striz on the centre of the apex; the meso- 
pleurze closely punctured at the base and apex, and with a 
broad belt of oblique strize in the middle; the metapleure 
closely striated, less distinctly towards the apex. The second
