RECLASSIFICATION OF MICROG ASTERINI 171 



existing segments indicate an antenna that is considerably longer than the body ; segment 16 

 fully twice as long as wide. 



Propodeum dull, with microsculpture and a few rugae in the area of the spiracle. Hind coxa 

 with faint microsculpture and pronounced satin-like sheen. No angle between abscissa 1 of the 

 radius and the transverse cubitus ; transverse cubitus characteristically long. 



Length: 3-4 mm. without ovipositor. 



o*. The five males associated with the single female (type) by Wilkinson show a confusing 

 variation in the colour of the hind legs ; the hind tibia and hind tarsus are paler than in the 

 female and much less sharply contrasted with the reddish-yellow femur. 



Java : Tjibodas, 5-7,000 ft. 



Type in the British Museum (Nat. Hist.). 



Apanteles ariadne sp. n. 



$. Antenna broken after the 14th segment ; this segment is twice as long as wide ; in 

 sundanus segment 14 is three times as long as wide. 



Whereas in sundanus the vannal lobe beyond its widest part shows a few projecting hairs, the 

 edge is quite bare in ariadne. Hind coxa relatively smaller, more shiny and without indication 

 of a satin-like sheen. 



Length: 3 mm. without ovipositor. 



Ceylon : Maskeliya, 4,200 ft., 15.vii.1919, 1 <j>, the TYPE, (N. K. Jardine). 

 S. India : Kadaj Kanal, 1 <$, (T. N. Campbell). 

 Type in the British Museum (Nat. Hist.). 



The MYCETOPHILUS-Grovp 



Metacarp at least four times as long as its distance from the apex of the radial cell, 

 usually much longer and almost closing the radial cell ; vannal lobe beyond its 

 widest part more or less straight or even slightly concave and virtually free from 

 projecting hairs ; cubitellan cell of the hind wing never higher than wide. Propo- 

 deum without trace of a median keel (cf . closely related group of nerion) and without 

 trace of areolation. Hypopygium long, deeply infolded along the middle line and 

 with numerous, lateral creases. Ovipositor sheath always longer than the hind tibia. 



Indo-oriental region. 



The group, as here defined, is somewhat artificial and may well contain species 

 that are aberrant or convergent members of other groups. Possible affinities will be 

 discussed under the separate species. 



Key to Species 

 Females 



1 Tergite 1 virtually parallel-sided. 



Legs, apart from coxae, pale yellow including the hind tarsi ; hind tibia without 

 apical infuscation and the hind basitarsus whitish towards base ; propodeum 

 densely, rather coarsely punctate across its anterior part . inunctus sp. n. (p. 173) 



- Tergite 1 distinctly, more usually strongly, narrowed to apex .... 2 



2 Tergite 1 only slightly but quite distinctly narrowed apically. 



Mesoscutum strongly shining, with a very fine, superficial punctation ; wings 

 hyaline ; metacarp almost closing the radial cell mycetophilus Wilkinson (p. 173) 



- Tergite 1 strongly narrowed to apex ......... 3
