XII, D,s Baker: Ichneumonoid Parasites 309 



spiracle is an oblique crenulate depression, passing to apical 

 margin; below the spiracle a fine lateral carina curves about 

 the lower half of spiracle and thence passes irregularly to apical 

 margin; below this carina, on the pleura, an oblique crenulated 

 depression; remainder of pleura smooth, Mesopleura smooth 

 and shining, without discal furrow. 



Abdomen longer than head and thorax together ; first segment 

 sessile, twice as broad at apex as at base, length one and one- 

 half times width at apex; second tergite as long as first, width 

 at apex nearly equal to length; third, fourth, fifth, and sixth 

 subequal in length, fourth very broad; first tergite medially 

 carinate only on basal half, second only on basal three fourths; 

 first four tergites finely, densely, longitudinally reticulate-rugose ; 

 fifth weakly punctate-striate at base only, the remainder of 

 fifth together with sixth smooth and shining; third and fourth 

 sutures only, deeply impressed and crenulate. Hind tibiae with 

 two long, equal, curved spurs; first hind tarsal joint as long as 

 three following together. 



Stigma large, about five times as long as broad, not at all 

 angulate at insertion of radius, this being nearer to base than 

 to apex; first abscissa of radius a little less than half length of 

 second; second cubital cell more than twice as long as high; 

 first transverse cubital very oblique, second nearly vertical; re- 

 current vein interstitial; parallel vein inserted below middle; 

 submedian cell considerably longer than median. 



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



Trigonophatnus philippinensis sp. nov. 



Ochraceous throughout; legs, antennae, palpi, and tegulae 

 somewhat paler; interocellar area piceous; wings faintly ob- 

 scured, stigma and veins on apical half of wing ochraceous, on 

 basal half piceous, second transverse cubital and recurrent veins 

 decolored. 



Female, length, 6.5 millimeters; ovipositor as long as sixth 

 tergite; hypopygidium very large. 



Head viewed from above with the medium-sized eyes strongly 

 bulging, vertex back of ocelli short, strongly narrowed back of 

 eyes; length of exposed cheek margin nearly twice the distance 

 from ocelli to eyes and greater than the distance from ocelli to 

 occipital carina; occipital carina subangulate at center; surface 

 of vertex smooth and shining ; ocelli on a distinctly raised prom- 

 inence and directed strongly sidewise, of medium size, dis- 

 tance between them subequal to the distance to eyes; distance 

 to occipital carina twice width between posterior ocelli; short
