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



While Macrostomionella philippinensis and M. similis differ in 

 a number of striking details, still they coincide in all important 

 generic characters. In color pattern the latter species bears a 

 remarkable resemblance to Rhogas cameroni sp. nov. 



Genus MEGARHOGAS Szepligeti 



This genus, based on two inadequately described species, ap- 

 peared first in Szepligeti's Braconidse," the two species, longipes 

 and minor, being from Celebes. On Plate II, fig. 26, is illustrated 

 a species called M. lutetis Szepl., which is not otherwise men- 

 tioned in the work, even in the Errata. 



No Philippine species shows the strongly clavate abdomen as 

 illustrated for M. luteus, although our species are clearly con- 

 generic. 



Synopsis of the species. 



a\ First abscissa of cubitus and first transverse cubitus forming an acute 

 angle. 

 b^. Radius in hind wings nearly parallel to costa; notauli, except an- 

 teriorly, not distinctly crenulate; mesopleura with a strong, oblique, 

 discal furrow; first abscissa of cubitus bisinuate; transverse median 



vein vertical; stigma piceous stigmaticiis sp. nov. 



b'. Radius in hind wings strongly upcurved at middle toward costal; 

 notauli strongly crenulate; mesopleura without oblique discal fur- 

 row; first abscissa of cubitus evenly upcurved; transverse median 



vein very oblique; stigma stramineous philippinensis sp. nov. 



a^. First abscissa of cubitus and first transverse cubitus forming a right 



angle; radius in hind wings strongly upcurved at middle toward costa. 



c\ Stigma largely piceous; general color obscure ferruginous; length, 10 



millimeters mindanaensis sp. nov. 



c". Stigma piceous only on upper posterior border; general color ochra- 

 ceous; length, 8 millimeters szepligetii sp. nov. 



Megarhogas stigmaticus sp. nov. 



Pale ferruginous, the abdomen darker above ; interocellar area 

 piceous ; antennae piceous, paler at extremities. Wings irregular- 

 ly suffused with pale ochraceous on basal half, remainder very 

 pale smoky; veins ochraceous; stigma piceous.
