I have seen no specimens of this species 
from the Philippines, and the accompany-

mens from the United States. 
Saissetia triangnlarum sp. nov. 
Adult female. — Occurring on the under- 
sides of the leaves of the host; about 1.5 
millimeters long by 2 millimeters or less 
wide, typically very broad-triangular, with both sides and angles 
rounded, widest far behind the middle, but the shape quite va- 
riable and sometimes asymmetrical; slightly convex, but with 
three broad and usually prominent ridges meeting at about the 
center of the body and radiating to the anterior and the two 
posterior lateral corners of the body; anterior corner more or 
less indented; spiracular spine regions very indistinctly in- 
dented; a light reddish brown in color in the dried state. 
Body of female. — Gradually clearing when boiled in caustic 
potash, the marginal areas first, finally becoming almost wholly 
transparent, the derm areolations not extending to the body 
margin, of the same type as those found in S. nigra, but much 
smaller, more delicate and even more irregular in size and shape 
than in that species; antennae 6-segmented, the third much the 
longest, about as long as the following three combined, the meas- 
urements in microns as follows:
