46 G. E. J. NIXON 



Host : Syhpta derogata Fab. (Pyraustidae). 



Like opacus and its close allies, this species has the mesosternum deeply channelled 

 with its lobes convex on each side of the channel. 



A . significans bears a strong resemblance to the African syleptae, which parasitises 

 the same host. It differs from syleptae as follows : — Eyes more distinctly con- 

 vergent below ; face distinctly punctate ; ist abscissa of the radius much longer 

 in proportion to the length of the transverse cubitus ; ovipositor sheath a little 

 longer. 



Apanteles coedicius sp. n. 



$. May be compared with opacus as follows : — 



Eyes hardly convergent. Face broad, shiny, almost polished and with only a trace of very 

 superficial punctation. Segment 17 of the antenna about one and half times longer than wide. 



Mesoscutum appearing contrastingly dull by comparison with the smooth, shiny top of head ; 

 duller, more evenly and closely punctate than in opacus. Disc of scutellum polished and with 

 virtually no trace of punctation. Stigma slightly more elongate than in opacus and metacarp 

 reaching even closer to apex of radial cell. 



Length: ca. 2 mm. without ovipositor. 



Philippines : Los Bafios, 1 $, the TYPE, (Baker). 

 Type in U.S. National Museum. 



The smallest of the species allied to opacus. Apart from size and duller meso- 

 scutum, extremely like opacus. 



Apanteles lyridice sp. n. 



9. Hind femur yellow but darkened above on about apical half ; hind tibia dark brown but 

 paler beneath towards base and with complete pale basal ring ; hind tarsus brown throughout. 

 Tergite (2 + 3) in great part yellow but the median field dark brown with median patch of 

 infuscation adjacent to it posteriorly. 



Head deep from back to front, smooth above and with faint satin-like sheen. Eyes strongly 

 convergent (Text-fig. 27). Face smooth and with hardly a trace of punctation. Antenna long 

 with segment 17 about one and half times longer than wide. 



Sculpture of mesoscutum and disc of scutellum hardly different from that of opacus, less dull 

 than in both cavifrons and crius. Propodeum with the complete, strongly developed areolation 

 typical of the species grouped around opacus. Hind coxa smooth, unsculptured. 



Ovipositor sheath about two thirds as long as the hind tibia.

 TYPE, 6.V.1954, 1 $, (M. & D. Townes). 

 Type in Coll. Townes. 



A most distinct species on colour alone. 



Apanteles crius sp. n. 



$. In spite of its very short ovipositor and enlarged apical tarsal segment on front and 

 middle legs (Text-fig. 12), this species is closely related to the opacus group of species. 



The very shiny, smooth-looking hind coxa is yellow beneath on apical half ; the hind femur is 

 infuscate except for a yellow base as in opacus.
