fifth and sixth segments together, and deeper than these seg- 

 ments, projecting nearly one third of its length beyond apex 

 of abdomen; ovipositor very short and curved. 



Stigma long, its length about five times its width, radius 

 inserted at two fifths from base; first abscissa of radius less 

 than half length of second; second cubital cell very long, not 

 narrowed apicaliy, the length nearly three times the width ; the 

 first transverse cubitus strongly oblique, the second perpendicular 

 and decolored; recurrent vein entering extreme apex of first 

 cubital cell; parallel vein straight and inserted at lower third; 

 submedian cell but little longer than median ; radial vein in hind 

 wings distinct but pale ; nervellus oblique and strongly curved. 



Luzon, Laguna, Mount Banahao {Baker). 



A second female specimen, from Mount Maquiling, is referred 

 to this species, although it differs considerably in color and 

 even in certain minor structural characters. The antennae and 

 the head are entirely pale; the mesonotum is pale and black- 

 bordered ; there is more dark color on the pleurae, and the median 

 metanotal groove is broader and more irregular. 



A third female specimen, from Mount Maquiling, has the an- 

 tennae dark and the stigma and the veins even darker, but it en- 

 tirely lacks all piceous and black markings on the body; the 

 metanotal groove is still broader and is crossed by three con- 

 spicuously strong rugae ; the recurrent vein enters first cubital cell 

 a little farther from its apex. Apart from these differences it 

 agrees in structural characters with the species described above ; 

 it may be called Rhogas cameroni var. flavus. 



The male of this species is smaller (5.5 millimeters), with 

 much less black on dorsum of abdomen, this often reduced to 

 median spots on first, fifth, and sixth tergites. The strise on 

 fourth to sixth tergites are straight, not oblique, and not quite 

 complete. 



The species is named for the late P. Cameron, a very prolific 

 writer on Oriental Hymenoptera. 



Rhogas (Aleiodes) palavanicus sp. nov. 



Antennae and thorax ochraceous ; head, abdomen, and legs pale 

 stramineous ; first, fourth, fifth, and sixth tergites slightly dark- 

 ened at base, second and third darkened along median longitudi- 

 nal line. Wings iridescent, very faintly smoky, and with three 

 large, indistinct, whitish areae — one in marginal cell, one in 

 anal cell, and one covering part of first cubital and first dis- 

 coidal cells. Veins, with stigma, stramineous or slightly smoky 

 in part, first abscissa of radius much darker, in sharp contrast
