with yellow, the four front cox and trochanters yellow below, as is also the 
base of the anterior femora, the face, clypeus, labrum, a line round the eye 
orbits, that on the outer side widened below, a semi-circular mark on either 
side of the apex of the pronotum, a line on either side of the middle of the 
mesonotum, it curving 1ound on the outer side of the base to the tegule, 
scutellums, two squarish marks on the base of the metanotum, the spines, 
a wide longitudinal mark on the upper side of the mesopleure, rounded at 
the base and apex and with an incision on the top shortly beyond the 
middle, a longer, narrower mark below, commencing farther back and with 
the apical half obliquely sloped, a mark below the hind wings, a wide 
longish mark on the upper part ef the metapleura, its apex projecting below, 
the top with a shorter and thicker projection and two semi-circular spots on 
the apex of the post-petiole. The apex of the sixth and the base of the

Bred from the Limacodid moth, Sibine trimacula. 
Pronotum and mesothorax closely punctured, the propleure, except at the 
base above, somewhat strongly longitudinally striated ; the scutellum smooth 
almost impunctate, its basal depression with four stout keels. The raised central 
part of the mesopleurz is smooth below, the depression below it obliquely striated, 
smooth at the apex. Metanotum coarsely reticulated, the basal reticulations 
roundly curved, the apex closer and transverse; the metapleure more finely, 
obliquely and closely striated, the striz curved and twisted. Metanotal spines 
large, thick, conical, wider at the base than they are long. Abdomen smooth, the 
first segment gradually widened at the apex. Tibize and tarsi shortly spinose, 
the second joint of the hind tarsi white : the others absent. 
Mesostenoideus atriceps, sp.n. 
Black, the abdomen and legs red, the tibie and tarsi paler, more fulvous 
coloured than the basal parts ; the following parts are whitish yellow ; the face, 
clypeus, a line on the inner orbits to the top of the occiput, where it is widened, 
a wider one on the lower three-fourths of the outer, widened below and extending 
to the bottom, leaving the malar space black, palpi, a broad line in the middle 
of the pronotum, teguls, a longish conical mark in the centre of the basal lobe of 
the mesonotum, a longish oval mark on the scutellar keels, scutellums, the keels 
at their sides, a longish wide line on the sides of the metanotum, commencing 
shortly beyond the keel and extending to the apex, a large line on the lower part 
of the propleure, the lower basal two-thirds becoming gradually widened below, 
the apex bluntly rounded, the tubercles, a large longitudinal mark on the lower
