XII, D, 6 Baker: Philippine Ichneumonoid Parasites, II 409 



terior median area plane and coarsely rugose. Scutellum ante- 

 riorly with two large fovese, separated by a sharp carina, each 

 fovea within having several low irregular rugse; posterior disk 

 of scutellum punctate. Metanotum very strongly, coarsely, irreg- 

 ularly rugose, and with a nearly straight, complete, median 

 carina; disk of metapleura coarsely punctate, behind coarsely 

 rugose; spiracle subcircular and with a sinuous, longitudinal, 

 sutural carina passing beneath it; mesopleura very coarsely, 

 irregularly rugose anteriorly, posteriorly shining, sparsely punc- 

 tate, and with an oblique, shallow depression, passing downward 

 and forward. 



Abdomen broadly sessile, slightly longer than head and thorax 

 together, widest at apex of second segment, fourth and following 

 segments but very little exserted, together shorter than third 

 segment; length of first tergite greater than its apical width, 

 basal width two thirds of apical ; second tergite as long as first, 

 little widening apically, sides straight, length subequal to apical 

 width, without depressions along basal border; third tergite 

 about three fourths length of second and slightly narrower ; re- 

 maining tergites very rapidly narrower and smooth and shining ; 

 first and second tergites very coarsely, strongly, irregularly, 

 longitudinally striate, third tergite finely, thickly, and completely 

 striate ; first and second tergites with a strong, straight, median 

 carina, but no carina discernible on third ; second suture narrow, 

 sharply impressed, minutely crenulate, and subconnate. 



Stigma large, about five times as long as wide, radius inserted 

 at two fifths of length from base; first abscissa of radius about 

 one third length of second; second cubital cell about one and 

 one-half times as long as wide, slightly narrowed apically; first 

 transverse cubitus a little oblique, second very slightly oblique; 

 recurrent vein inserted in first cubital cell a distance from apex 

 a little less than length of first abscissa of radius and about half 

 the length of second transverse cubital, intervening vein not 

 swollen; parallel vein inserted at lower third, broadly curved 

 before insertion ; submedian cell exceeding median by the length 

 of the oblique transverse median vein ; radius in hind wings very 

 weak and straight; nervellus curved and a little oblique. 



Luzon, Laguna, Mount Maquiling (Baker). 

 ■ This species is very close to Rhogas brownii sp. nov. in general 

 appearance, but is distinct in various important structural 

 characters. 



Named for Rev. Francisco de P. Sanchez, S. J., of the Ateneo 

 de Manila, who came to the Philippine Islands fifty years ago 

 and is still an enthusiastic naturalist.
