3 Flagellum short, thick, with all the segments, except the first and the last, hardly 



longer than wide ; front tarsal segment 5 without a spine ; thorax broader ; 

 tergite 1 less narrow ; hind coxa red. 



Thorax much flattened ; tergite 1 and 2 almost yellowish and resembling the legs 

 in colour ; flagellum pale but darkened apically ; hind tibia and hind tarsus (Text- 

 fig. 217) . . . . . . . . . plancina sp. n. 



India: Punjab, Miranpur, iv.1938, 3 $$, 3 $$, Chichawatni, viii.1928, 2 $<$, ex 

 Plectoptera reflexa v. 5 <3$, 3 $$, Terah Plain, iv.i $, Daphar Plain, v. 1938, 1 <$, 

 Arafwala Plain, v. 1938, 1 $, Shikapur, Newman Plain, v. 1938, 1 $ ; United 

 Provinces, Allahabad, 3. iv.1938, 1 $, the TYPE, ex Cacoecia sp.. All the above 

 material bred in association with the Dahlbergia sissoo entomological survey. Type 

 in the British Museum (Nat. Hist.). 



Host: Plectoptera reflexa Guen. (Phalaenidae), Cacoecia sp. (Tortricidae). 



The males of plancina are much darker than the females and are sometimes 

 nearly black ; the antenna is considerably longer the body. In most females there 

 is a contrast between the paler base of the gaster and the rest of the body but some- 

 times the pale colour is more extensive and the whole insect becomes predominantly 

 reddish yellow. 



- Flagellum longer, slender, all the segments longer than wide ; front tarsal segment 5 



with a fine spine ; thorax less broad ; tergite 1 more slender (Text-fig. 213) ; hind 

 coxa pale only towards apex. 



Thorax entirely black ...... pyrogrammae sp. n. 



New Guinea: Lae, xii.1957, J ?• tne TYPE, 1 5* ; Rabaul, vii.ix. 2 $$ ; 

 Bougainville, v. i960, 1 $, all bred from Agonoxena pyrogramma, (R. W. Paine). 



Australia: Queensland, Tully, ii,i96i, 4 $$, ex Agonoxena pyrogramma (R. W. 

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



Host: Agonoxena pyrogramma Meyrick (Agonoxenidae). 



4 Wings distinctly smoky ; metacarp short, not at all longer than the stigma and 



hardly two and a half times as long as its distance from the apex of the radial cell. 



Stigma short, broad, as in congoensis (cf. Text-fig. 219) ; median field of tergite 2 

 much shorter than 3 and strongly transverse with weak oblique aciculation laterally; 

 flagellum as in congoensis but with simple pubescence and the segments lacking the 

 somewhat moniliform appearance of those of congoensis ; hind legs as in congoensis ; 

 hypopygium blackened and heavily sclerotised, altogether more strongly developed 

 than in congoensis ; ovipositor sheath broadly truncate ; inner spur of the hind 

 tibia only just reaching beyond the middle of the hind basitarsus and only a little 

 longer than the outer one (Text-fig. 216) . . . . . . parmula sp. n. 



S. Africa: Cape Province, Ceres, iv.1925, 1 $, the TYPE, (R. E. Turner). Type in 

 the British Museum (Nat. Hist.). 



I doubtfully associate with this species a second female (Mossel Bay, xii, (R. E. T.), 

 in which the wings are not smoky and the stigma is slightly less broad ; also the face 

 is slightly more transverse and slightly duller by reason of a very superficial but 

 coarse punctation. This specimen may belong to a further species, closely allied to 

 parmula. The short metacarp and the shape of the median field of tergite 2 are both 

 important for the recognition of parmula. 



- Wings not at all smoky ; metacarp less short, distinctly longer than the stigma and 



longer in proportion to its distance from the apex of the radial cell ; median field of 

 tergite 2, though poorly defined, less transverse. 



Inner spur of the hind tibia longer in proportion to the length of the hind basitar- 

 sus and also longer in proportion to the length of the outer spur ... 5 



5 Antenna longer, not noticeably tapering towards apex and with flagellar segments 4-7 



at least one and a half times longer than wide ; tergite 1 narrower, pale only at base; 

 median field of tergite 2 hardly transverse (Text-fig. 218) . . astydamia sp. n.
