half of third with a sharp median carina; all tergites, except 

 seventh, finely, longitudinally reticulate-rugose; seventh shining, 

 sparsely, shallowly punctate. Hind tibiae with two long, curved, 

 subequal, naked spurs, which are longer than fourth tarsal joint. 



Stigma very long and narrow, more than four times as long 

 as wide; radius inserted at basal third, apical two thirds only 

 slightly narrowed to the rather blunt apex; first abscissa of 

 radius about one third length of second ; second cubital cell three 

 times as long as wide; both transverse cubitals oblique and 

 decolored, the first angulate at middle ; recurrent vein inserted a 

 short distance before first transverse cubital, intervening vein 

 decolored; parallel vein inserted a little below middle. In hind 

 wings second recurrent joins anterior vein at origin of radius, 

 which is strong and dark like the other veins ; nervellus oblique. 



Luzon, Laguna, Mount Maquiling (coll. Baker). 



This very remarkable insect is unique among the Rhogadins 

 of the Philippines, not only in its extraordinary maxillary palpi, 

 but in the wing color, in the stigma, and in the sculpturing of face 

 and of metanotum, 



Macrostomionella similis sp. nov. 



Ochraceous; borders of mesonotum piceous; interocellar area, 

 mesonotum, and abdominal dorsum irregularly black on median 

 half. Antennse piceous; wings faintly smoky, veins and stigma 

 pale sordid stramineous ; costal margin of stigma much brighter ; 

 basal vein dark. 



Male, length, 5.5 millimeters. 



Head viewed from above with eyes strongly bulging beyond 

 head outline, vertex back of eyes slightly shorter than ocellar 

 area, but longer than exposed cheek margin; the surface with 

 a few subobsolete punctures; ocelli very large, nearer to eyes 

 and to each other than once their own diameter, but one and 

 two-thirds times their diameter from the occipital margin. Face 

 subquadrate, slightly broader than long, sides nearly parallel; 

 surface subobsoletely punctate-rugose, medially very short-carin- 

 ately elevated below antennse; mouth opening broadly elliptical; 

 clypeus semilunate, width one and one-half times the length, 

 basal suture highly arched; clypeal pits twice their diameter 

 from eyes; eyes very gently emarginate at antennse. Head 

 viewed from side with upper part of face very strongly pro- 

 jecting; malar space longer than lower width of cheek; cheek 

 below, one third diameter of eye, gradually narrowing above; 

 ocelli prominent ; eye outline broadly elliptical, broader on upper
