I had at first confounded this species with Leptomantis 
albella Burm.; but, after having received Hebard’s excellent 
paper, I am convinced that I had before me the new species 
described by him as representing a new genus. This species 
cannot be rare and, in any case, it appears to be widely distri- 
buted over the Philippines. It is easily distinguishable from 
Leptomantis lactea by the smaller size and the perfectly hyaline, 
iridescent wings, whereas that species has distinctly milky wings 
with white costal margin on elytre. A pair of dark spots, 
apparently common in L. lactea, is not frequently to be found 
in Aetella bakeri on the metazone of the pronotum, as far 
behind the transverse sulcus as the length of the prozone.

DEROPLATINA 
Deropletys philippinica sp. nov. 
Distinguished from all other members of the genus by the 
narrower pronotum, resembling somewhat in shape that of 
Sphodrepoda medioconstricta Wood-Mason. Prozone of prono- 
tum one-third the length of metazone, the latter with a longitudi- 
nal median keel in its posterior half. The expanded part of 
the prozone is not more than half the transverse diameter of 
the prozone itself, narrowed cephalad and with rounded anterior 
margin; in its anterior third the metazone is parallel-sided, 
widens toward its second third, and is again narrowed to its 
posterior end, thus forming a sinuous line on each side; wings 
extending much beyond apex of abdomen, the anterior ones 
feebly dilated toward apex, which is bluntly triangular; costal 
area dilated only at base, the greater portion toward the apex 
very narrow; stigma distinct, small, triangular; hind wings with 
the costal area angularly produced (more so than the fore- 
wings) ; middle and hind legs very slender, with small, trian- 
gular, somewhat denticulated lobules near apices of tibia; ex- 
posed parts dead-leaf-colored above and below; inner face of
