first and the apical black. Wings hyaline, the stigma and nervures black, the 
apical nervures fuscous, the areolet square, its apical nervure faint, the recurrent 
nervure received in the middle, the transverse median nervure interstitial. 
Male. 
Length 4 m.m. 
The underside of the antennal scape yellow, of the flagelloid fuscous. Face 
sparsely punctured. Mesonotum opaque, closely, finely punctured. Base of 
metanotum opaque and closely punctured ; the part behind the keel finely longi- 
tudinally striated at the base, the striz roundly curved in the centre, the apical 
slope more closely, strongly and regularly striated. Propleure smooth. Meso- 
pleure closely, regularly and distinctly longitudinally striated ; the metapleure 
more strongly obliquely so. The tarsi are closely, shortly spinose. 
Cryptanura cinctipes, sp.n. 
Black, the abdomen and legs red, the sixth to twelvth joints of the antenne 
except above, palpi, a spot in the middle of the clypeus, rounded above, trans- 
verse below, a line on the inner and upper eye orbits, half the width of the 
space between the ocelli and the eyes, a small spot, roundly narrowed below, 
on the malar space, a line round the base of the prothorax, a wider one on 
the sides of the pronotum, tegule, tubercles, scutellum, the usual spot behind 
the posterior wings, metanotal spines, a line on the apical three-fourths of the 
lower part of the mesopleure, its upper basal two-thirds widened above, the 
base oblique, the apex rounded, a more obscure line along the lower part 
of the furrow on the breast, a conical mark, twice longer than wide, on the 
lower apical part of the metapleure, a broad continuous line on the apex 
of the first, second and seventh, a narrower line on the sides of the third 
and the fourth anterior cox, whitish yellow, the sixth and apical abdominal 
segments blackish ; wings hyaline, the stigma and nervures black, the parastigma 
white ; a cloud beyond and touching the transverse median and tranverse basal 
nervures, not reaching to the costa and extending in front to the innerside of the 
latter nervure, its outer side paler, irregular and becoming gradually wider towards 
the posterior end, and an irregular apical cloud, commencing near the apex of 
the apical two-thirds of the apical abscissa of the radius, reaching to the apex 
of the radial cellule, straight on the inner side, roundly irregularly narrowed on 
the outer ; the transverse median nervure received shortly behind the transverse 
basal ; the areolet slightly narrowed and open in front, the recurrent nervure 
received shortly before the middle. Female.

spines white, the latter of a clearer white, the flagellum black, the underside of 
the 7th to 13th-14th-joints white ; abdomen black, the base and apex of the first, 
the apex of the second and third broadly—the apical fourth of the second and 
the third of the latter—and the sixth and seventh entirely with the ventral
