Philippines : Island of Basilan, i $, the TYPE, {Baker). 

 Type in the U.S. National Museum. 



Perhaps related to araeceri on the shape of the first tergite. Not a very distinc- 

 tive looking species but probably characterized to some extent by the length of the 

 median field of tergite (2 + 3) in relation to the length of the rest of the tergite. 



Apanteles orus sp. n. 



This species is like leptoura in having a strongly sculptured head. 

 $. Hind tibia deeply infuscate almost throughout, only very faintly paler at extreme base. 

 Setae of the fore wing slightly darker. Antenna broken but evidently long, with segment 15 

 twice as long as wide. 



Philippines : Luzon, Mt. Makiling, 1 $, the TYPE, {Baker). 

 Type in the U.S. National Museum. 



Apanteles eriphyle sp. n. 



9. Another species with coarsely rugose-punctate frons and vertex, more closely resembling 

 orus than leptoura on account of the sculpture of the mesoscutum, long metacarp and strongly 

 narrowed first tergite. 



Stigma almost evenly brown. 



Head thicker from back to front than in orus. Antenna as long as the body, somewhat taper- 

 ing towards apex, with segment 14 about two and a half times longer than wide ; flagellum rather 

 bristly. Spines of the outer side of the hind tibia more numerous and more upstanding than in 

 orus. Ovipositor sheath downcurved towards apex, clothed densely with short, almost ad- 

 pressed hairs ; these hairs are slightly more erect in orus. 



Philippines : Los Banos, 2 $$, one the TYPE, {Baker). 

 Type in the U.S. National Museum. 



I have no doubts about the specific validity of eriphyle and orus. Neither of them 

 is easily confused with any other species dealt with in this paper. 



Apanteles tigasis sp. n. 



9. Another species related to orus and eriphyle as well as to the leptoura-complex but differs 

 from all these species in the combination of entirely dark stigma and narrower hind wing. 



Hind femur brown ; hind tibia becoming yellowish on rather more than basal half ; hind 

 tarsus deeply infuscate throughout. 



Face and clypeus much flattened ; face with large, somewhat irregular punctures that are 

 more crowded towards the middle line. Antenna broken but the existing segments indicate a 

 decidedly bristly flagellum. 



Mesoscutum sharply punctate ; the punctures fairly large and well separated ; at posterior 

 end of notaulic course is a distinct zone of striate-punctation. Disc of scutellum rather strongly 

 narrowed behind, polished and virtually without trace of sculpture. Propodeum rather short, 

 with the costula weakly indicated ; postero-lateral areas distinctly transverse. Hind tarsus 

 with distinctly bristly appearance. 



Horizontal part of tergite 1 dull, owing to microscopic surface sculpture and covered with 

 oblong punctures ; a deep, medial furrow present. 



Sumatra : Fort de Kock, 920 m. 1925, 1 $, the TYPE, {Jacobson).
