XII, D, 6 Baker: Philippine Ichneumonoid Parasites, II 395 



Rhogas (Aleiodes) bicolor sp. nov. 



Ferruginous, hind tibise and tarsi darker; antennae, metano- 

 tum, and a large part of first three tergites (excepting a median 

 spot on second) piceous. Wings rather strongly suffused with 

 a smoky tinge, veins dark-colored, basal third of stigma pale. 



Male, length, 5.75 millimeters. 



Head viewed from above transverse, broad behind the eyes; 

 eyes of medium size, distance between them about equal to the 

 distance from occipital carina to anterior ocellus ; vertex opaque 

 and shagreened; occipital carina rather suddenly incurved at 

 middle; length of vertex back of ocelli distinctly greater than 

 length of the oblique exposed cheek margin and slightly greater 

 than the length of entire ocellar area; ocelli large, rather close, 

 distance from ocelli to eyes slightly more than interocellar dis- 

 tance, but less than long diameter of an ocellus ; distance between 

 hind ocelli much less than long diameter of an ocellus ; anterior 

 ocellus slightly farther removed. 



Face to. mouth about as long as wide, eye margins below not 

 strongly incurved, very shortly, medially, umbo-carinate just 

 below antennae, surface shagreened and shallowly, transversely 

 v/rinkled above; mouth opening subelliptical and small; clypeus 

 large, strongly swollen, basal suture highly arched, length and 

 width subequal; clypeal pits small, distant from eyes about 

 five times their diameter. Head viewed from side with face 

 sharply prominent below antennae, and clypeus very prominent ; 

 cheek broad, a little less than half the diameter of eye, through- 

 out most of its length with outer margin parallel to eye margin ; 

 malar space rather small, about as long as width of cheek; eye 

 large, broadly subelliptical, slightly broader on lower half. Max- 

 illary palpi slender, terete, not reaching tegulae ; third and fourth 

 joints subequal; fifth and sixth subequal and shorter than 

 fourth. 



Antennae subequal to entire body in length; scape broad, 

 not at all narrowed apically, its length about one and one-half 

 times the width at apex ; f unicle very short and broad, less than 

 half length of scape; length of middle flagellar joints about 

 one and one-half times the width. 



Mesonotum obscurely trilobed, middle lobe short, notauli 

 shallow anteriorly, but deep, broad, and strongly converging 

 posteriorly; surface shagreened, lateral lobes posteriorly, ob- 

 scurely, transversely rugulose, posterior median area plane 

 and strongly rugose. Scutellum anteriorly with six small equal 

 foveae, the low separating carinje not complete anteriorly;
