3. Hemipsocus chloroticus stenostigmus , new variety (fig. 1, d).

Differs from the numerous chloroticus seen in having the pterostigma much narrower, only little more than one half as wide as the costal area before it, and the posterior side, instead of being plainly bowed, is straight for most of the distance; the radial sector and medius connected by a short cross vein usually united at one point. Fork of radial sector is as long as its pedicel; fork of medius 3 times as long as pedicel; areola postica subtriangular, more than twice as long as high.

Agana , May 4, 1 small male .

Variations are so common in the venation of Psocidae that it is hardly safe to call this a separate species, even though the shape of the pterostigma is quite constant.

True H. chloroticus occurs from Ceylon eastward to Formosa, and also in the Philippines.
