$. It is convenient to compare pycnos with phaenna. 



Head markedly transverse as in mycetophilus (cf. Text-fig. 192). Face virtually impunctate. 

 Antenna relatively less powerfully built but its apex (3-4 segs.) very slightly thickened with the 

 preapical segment not longer than wide and distinctly a little shorter on one side than the other ; 

 no pale tip to the antenna ; flagellum slightly more bristly than in phaenna. 



Mesoscutum somewhat dull, densely and, on the whole, sharply punctate. Disc of scutellum 

 flattened, as in phaenna, its posterior margin separated from the polished posterior band of the 

 scutellum by a row of sharp punctures ; hardly a trace of such punctures in phaenna and no 

 trace at all in mycetophilus and inunctus. Propodeum with more rugosity above the posterior 

 orifice and within the postero-lateral corners. Transverse cubitus strikingly long, relatively 

 longer than in any other species included in the group ; distinctly longer than abscissa 1 of 

 radius. Claws as well developed as in phaenna. 



Tergite 1 and (2 + 3) (Text-fig. 190) ; the surface of tergite 1 is finely aciculate-rugose with 

 scattered punctures where it turns over ; posterior smooth tip not occupying the whole of the 

 apex as in phaenna. Ovipositor sheath about one and a third times longer than the hind tibia ; 

 ovipositor straight, downcurved at tip. 



Length: 3-5 mm. without ovipositor.

This species and phaenna bear a strong resemblance to the Philippine species of 

 the nerion-gronp. The resemblance may be just another example of a baffling 

 convergence. But, nevertheless, if these Philippine species of the nerion-group 

 lacked the percurrent propodeal furrow which is their distinctive feature, I should 

 have had to include them among the heterogeneous members of the mycetophilus- 

 group. 



The membranous apical margin of tergites 4 and 5 is a striking feature of pycnos, 

 though its true taxonomic value is hard to assess on a single specimen. 



Apanteles lampe sp. n. 



$. Distinguishable from all the other species of the group by its large eyes (Text-fig. 184). 



Hind femur and hind tibia brownish-red. Wings faintly tinted with brown. Whole body 

 dark brown with a faint reddish tint. 



Face smooth, impunctate. Head rather deep from back to front. Vertex between the ocelli 

 and the eye-margin very faintly punctate and with satin-like sheen. Antenna broken but the 

 existing 10 segments of flagellum thin and with long, bristly pubescence. 



Mesoscutum faintly dull, with satin-like sheen and with fine sculpture not clearly resolvable 

 as distinct punctation. Disc of scutellum strongly shining and with weak indication of puncta- 

 tion. Propodeum shiny, with some sort of rugosity almost everywhere. Fore wing not so 

 densely setose at base as in pyncos and phaenna ; abscissa 1 of the radius slightly curved, not 

 longer than the transverse cubitus. Legs relatively stouter and shorter than in pycnos and 

 phaenna ; inner spur of the hind leg fully reaching middle of basal segment of tarsus ; claws 

 strongly developed as in pycnos and phaenna. Vannal lobe beyond its widest part with sparse 

 but distinctly projecting hairs. 



Apical, polished lunule of tergite 1 occupying whole of tip, though transverse and not so 

 sharply differentiated as in phaenna.
