mate. Legs covered with stiff hair; thespurs minute, as are also the claws. 
Antenne shorter than the body; the 3rd joint longer than the 4th. The 
thorax appears short as compared with the abdomen, it being not much 
longer than the basal 2 abdominal segments. The hind coxe are 3 times 
longer than wide. The radial cellule in hind wings undivided. 
LInssophrymnus annulicaudis, sp.n. 
Black, the palpi, an oblique mark, longer than wide and of equal width, on the 
outerside of the malar space and a broad band near the apex of the ovipositor— 
longer than the terminal black part—white, the tarsi tinged with testaceous ; 
wings hyaline, iridescent, the stigma and nervures black. The face, pleure 
and legs thickly covered with white hair ; the base of abdomen more sparsely 
with white erect hair. The base of the 2nd abscissa of cubitus, the posterior 
part of the Ist transverse cubital nervure and the 2nd transverse cubital 
widely, bullated. Female. Length 12 m.m. ; terebra 12 m.m. 
Front and vertex strongly closely transversely striated, the occiput smooth 
and shining ; the striz on the front weaker and closer than on the vertex ; the 
face finely rugose, the sculpture hidden by the long white dense pubescence. 
Te nples obliquely striated above, the rest smooth ; the occiput distinctly mar- 
gined. Pronotum at the base with a raised piceous margin ; the apex broadly 
raised clearly separated from the mesonotum ; it is, as is also the upper, apical 
part of the pleure, strongly striated, the striz clearly separated. Base and sides 
of the mesonotum rather strongly striated, the strize more or less rounded, the 
apical central part is more strongly reticulated, at the apex strongly longi- 
tudinally striated. Scutellum closely, not very strongly, but distinctly punc- 
tured. Metanotum transversely reticulated ; stout keel down the middle of 
the basal half ; the part bordering the base of this coarsely aciculated and with 
some curved longitudinal stri# at the apex and sides of the aciculated part. 
Metapleure reticulated, the base of the inner part coarsely aciculated, the rest 
closely, strongly, obliquely striated. Upper central part of prop!eure shin ng, 
depressed, strongly striated, its apical part below is bordered by a stout keel, 
above it is irregularly reticulated, with 2 or 3 stout keels at the base. Meso- 
pleure at the base above finely, below more strongly, irregularly striated. Basal 
half ef the lst abdominal segment finely, closely reticulated, the rest finely 
longitudinally striated ; the 2nd and 3rd segments are more strongly, regularly 
longitudinally striated ; the 4th segment aciculated, the other segments shining, 
smooth, bare, except for a few long white hairson the apices. The antenne 
have the apical half brownish.

Black, the thorax red, a large irregular blackish mark on the apical two-thirds 
of the metanotum, and the greater part of the metapleure black ; wings black- 
ish violaceous, tinged with violaceous, especially towards the apex, the stigma 
an neryures black ; the 2nd cubital cellule in front as long as the 2nd transverse
