RECLASSIFICATION OF MICROGASTERINI 93 



Tergite 1 strongly narrowed behind, but not so much as in the two following species (cf. Text- 

 fig. 72). Median field of tergite (2 + 3) angled laterally at about 45 degrees. Ovipositor sheath 

 hardly one and a quarter times longer than the hind tibia, its sheaths clothed with long up- 

 standing hairs. 



Length: ca. 35 mm. without ovipositor. 



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

 Type in the U.S. National Museum. 



This is a heavily built species, characterized essentially by the fading out medially 

 of the mesoscutal sculpture. 



Apanteles cestius sp. n. 



9- May be compared with vacillans as follows: — 



Hind coxa becoming yellow on distal half ; hind tarsus only weakly infuscate. 



Distance between the posterior ocellus and the eye-margin only very slightly greater than the 

 longer diameter of the ocellus, the eye slightly nearer to the ocellus than in vacillans. Face 

 virtually without trace of punctation. Head less transverse (cf. Text-fig. 82). Antenna very 

 long and powerful, longer than the body with segment 16 about twice as long as wide. 



Mesoscutum decidedly dull by comparison with vacillans ; posterior end of notaulic course 

 somewhat depressed with the punctures large here but without trace of longitudinal elements. 

 Propodeum slightly longer, very strongly areolated ; the areola itself deeply hollowed out and 

 almost polished. First abscissa of the radius almost at right angles to the stigma ; hind wing 

 narrow ; as in vacillans, the metacarp is extremely long and almost closes the radial cell. Spines 

 along upper edge of hind tibia finer and sparser ; hind femur less thick. Mesopleurum in front 

 with a closer, finer punctation. 



Length: ca. 3-5 mm. without ovipositor. 



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

 Type in the U.S. National Museum. 



This species is abundantly distinct from vacillans on the sculpture of the meso- 

 scutum. Specifically it is distinct on the length of the antenna. I regard it as 

 transitional between the ater-gxoxvp s.l. and the much smaller taeniaticornis-group, 

 also dealt with in this paper. 



Apanteles dis simile sp. n. 



$. Differs from cestius as follows: — 



The hind coxa is entirely dark but the colour of the legs is otherwise similar in the two species. 



Face completely smooth except for a faint satin-like sheen. Antenna shorter with segment 16 

 only about one and a third times longer than wide. 



Sculpture of mesoscutum much more typical of the ater-group s.l ; at the posterior end of the 

 notaulic course, the punctures are arranged in such a way as to form a small zone of distinct 

 striate-punctation. 



Tergite 1 more narrowed behind (Text-fig. 78). 



Philippines : Mindanao, Davao, 1 $, the TYPE, (Baker). 

 Type in the U.S. National Museum. 



In the form of the first tergite of the gaster, this species is even more transitional 

 towards the taeniaticorni s-group than cestius.
