RECLASSIFICATION OF MICROG ASTERIN I 191 



S. Africa: Louis Trichardt, 5 tS , one the TYPE, 1 J, bred iv.1935, ex larva 

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



Host: Epichorista ioniephala Meyrick (Tortricidae) . 



The antenna of the male is shorter and thinner than that of the Indian plancina 

 and the wings show no sexual dimorphism. 

 - Antenna shorter, noticeably tapering towards apex and with flagellar segments 4-7 

 only one and a quarter times longer than wide ; tergite 1 wider, evenly reddish 

 throughout ; median field of tergite 1 much more obviously transverse 



symmysta sp. n. 



S. Africa: Pondoland, Port St. John, 12-30. vi.1923, 1 ?, the TYPE, (R. E. 

 Turner), Transkei, Umtata, 18.ii-18.iii. 1923, 1 $, (/?. E. T.). Type in the British 

 Museum (Nat. Hist.). 



This species has the fate smoother than parmula ; both species need further 

 study. 



The FORMOSUS-Grovp 



The species of this group seem to be all closely and naturally related with regard 

 to the main characters by which I have segregated them. But within the group 

 specific divergences are fairly wide. Salient features are the following :- 



Side of pronotum without trace of a dorsal furrow. First abscissa of the discoideus 

 considerably shorter than the second, usually about half as long ; always a distinct 

 angle between the 1st abscissa of the radius and the transverse cubitus ; vannal lobe 

 beyond its widest part with straight or slightly concave edge and here without a 

 distinct fringe of projecting hairs (but cf. gratiosus W'ilk.). Apical segment of the 

 front tarsus of the female often with a spine. Tergite (2 -[- 3) either without a 

 median held and with two short sulci directed towards the lateral margin of the seg- 

 ment (formosus Wesm., Text-fig. 228) or, if median held is present then this is obvi- 

 ously triangular. Hypopygium evenly sclerotised all over. Ovipositor short, more 

 or less concealed. 



Old and New World. Not rich in species ; most of those known to me are from 

 Africa. 



A. cuspidalis de Saeger (1944) and A. simiilissinuts de Saeger (1944) almost 

 certainly belong here but are not included in the key, as I have not seen them. 



Key to Species 

 Females 



1 Eyes very large so that the face is longer than wide ; posterior ocellus separated from 



the eye-margin by a distance not greater than the longer diameter of the ocellus . 2 



- Eyes smaller, of normal size, the face in consequence not longer than wide ; posterior 

 ocellus separated from the eye-margin by a distance equal to at least nearly twice 

 the longer diameter of the ocellus ......... 3 



2 Thorax, except for the almost yellow pronotum and propleurum, brownish ; 



posterior ocellus separated from the eye-margin by about its longer diameter ; 1st 

 abscissa of the discoideus hardly half as long as the 2nd ; apical segment of the 

 front tarsus without trace of a spine. 



Antenna very slender, the preapical segment fully three times as long as wide ; 

 tergite 1 parallel-sided, about twice as long as wide, yellowish-red, more especially
