RECLASSIFICATION OF MICROG ASTERINI 217 



The MORATA -Group 



The two species I include in this group are not very closely related and the only 

 difference of value between them as a group, and resplendens lies in the fact that they 

 have a normal scutellar disc. 



Key to Species 

 Females and Males 



A Hypopygium short, evenly sclerotised all over, without a trace of lateral creases ; ovi- 

 positor sheath hardly two thirds as long as the hind tibia ; hind coxa bright yellow ; 

 1st abscissa of the discoideus considerably shorter than the 2nd ; tergite 1 bright 

 reddish-yellow, almost subquadrate ; vannal lobe beyond its widest part without 

 fringe of hairs. 



Ovipositor rather thick (Text-fig. 258) ; gastcr bright reddish-yellow except 

 for the dorsal surface posterior to the 1st tergite ; mesoscutum rather coarsely 

 punctate, the punctures anteriorly becoming contiguous. Parameres of the male 

 genitalia unusually large. ....... morata (Wilkinson) 30 



Australia: Victoria. Type in the British Museum (Nat. Hist.). 

 Host: Thyridopteryx herrichi Westwood (Psychidae). 

 B Hypopygium long, membranous and tightly folded along the middle line but without 

 lateral, longitudinal creases ; ovipositor sheath about one and one third times lon- 

 ger than the hind tibia ; hind coxa dark brown but paler at tip ; 1st abscissa of the 

 discoideus a little shorter than the 2nd (Text-fig. 225) ; tergite 1 brown throughout, 

 narrower and with an indication of punctate-rugosity along sides posteriorly ; 

 vannal lobe beyond its widest part with distinct fringe of hairs (Text-fig. 264). 



Ovipositor much less thick than in morata ; gaster yellow beneath but the whole 

 of the upper surface brown ; mesoscutum, on the whole, with a very fine, super- 

 ficial punctation. The male has tergite 1 more narrowed behind than the female ; 

 the genitalia are without the exaggerated parameres of morata . . . ceto sp. n. 



Australia: F. C. T., Blundell's, 1931, 2 $$, one the TYPE, 3 ^d*. bred, i.1931, 

 from ' Eriococcus complex on Eucalyptus' , {A. L. Tonnoir). Type in the British 

 Museum (Nat. Hist.). 



The PSARAE-Group 



Ocelli in a very low triangle, the transverse, posterior tangent to the median ocellus cutting 

 deeply into the posterior pair. Lateral, polished field of the scutellum not pushed far forwards 

 and hence not cutting off between itself and the disc a long, parallel-sided furrow (cf. zonaria- 

 group). First abscissa of the radius much longer than the 1st transverse cubitus ; 2nd trans- 

 verse cubitus received onto the 1st considerably proximal to the junction of the two radial 

 abscissae (Text-fig. 273). Vannal lobe beyond its widest part without a hair-fringe. Pro- 

 podeum highly polished, and with strong, medial keel (Text-fig. 266). Longer spur of the middle 

 tibia reaching apex of middle basitarsus and terminating in a long bristle. 



The species of this group are large, heavily built insects, and some of them are 

 entirely fulvous in colour. They form a very homogeneous unit.
