RECLASSIFICATION OF MICROGASTERINI 255 



Europe : Finland, Kuusamo, 1 $, the TYPE, (Frey), Novorossiisk, 1 $, (Luther). 

 Type in Coll. Hellen. 



Important for recognising this little species are the extremely fine sculpture of the 

 mesoscutum and the form of tergite (2 + 3)- I am at a loss to suggest close allies. 



The SPRETUS-Grovp 



The group is essentially characterized by the short antenna of the female and the form of 

 tergites 1 and (2 + 3). 



The head, in a lateral view, is of characteristic shape (Text-fig. 325). Face more or less trans- 

 versely striate-punctate. Mesoscutum shiny, strongly punctate to rugose-punctate but without 

 microsculpture between the punctures ; disc of scutellum flattened, shiny, with or without 

 widely spaced punctures. Hind coxa flattened on outer side. First abscissa of the radius placed 

 at right angles to the stigma ; 1st abscissa of the discoideus as long as the 2nd. 



Key to Species 



1 Gaster in greater part yellow ; hind coxa entirely yellow ; antenna less thick, with 



segments 10-12 about one and a half times longer than wide. 



F'lagellum without bristly pubescence ; mesoscutum very coarsely punctate, 

 almost rugose-punctate ; disc of scutellum shiny, with large, scattered punctures ; 

 its extreme tip with traces of fine rugosity interrupting the posterior, polished band 

 of the scutellum ; inner spur of the hind tibia almost as long as the hind basitarsus; 

 propodeum with coarse rugosity ; metacarp about two and a half times as long as 

 its distance from the apex of the radial cell ; stigma as in austrina 



tomentosa (Wilkinson) 57 



India: Dehra Dun (type locality). Type in the British Museum (Nat. Hist.). 



Host : The type series was recorded as parasitising a Pyralid defoliating Terminalia 

 tomentosa. In B.M. (N.H.) is additional material bred from Macalla sp. (Pyralidae), 

 defoliating Tectona grandis. A gregarious parasite. 



- Gaster black or blackish ; hind coxa dark on at least posterior half ; antenna thick ; 



with segments 10-12 hardly longer than wide ....... 2 



2 Hind coxa black ; hind tibia very dark but with a faintly paler area just proximal to 



middle but not extending to base ; metacarp about one and one third times longer 

 than its distance from the apex of the radial cell ; stigma broader (Text-fig. 315) ; 

 disc of scutellum rugulose at extreme tip, its surface otherwise with widely separated 

 punctures ; propodeum with a predominating sculpture of coarse punctation ; 

 flagellum without bristly pubescence ; gaster (Text-fig. 319) spretus (Marshall) 58 



Europe: Only specimens from England seen. Type presumably lost. 



Host: Dioryctria palnmbella F. (Kent, Dartford Heath, bred in May by R. L. E. 

 Ford), Euzophera consociella Hiibner (Phycitidae). A solitary parasite. 



This species, as far as European Microgasterinae are concerned, is quite unmis- 

 takeable. 



- Hind coxa reddish yellow beyond middle ; hind tibia yellow on fully basal half ; meta- 



carp about three times as long as its distance from the apex of the radial cell ; stigma 

 slightly less broad than in spretus (cf. Text-fig. 315) ; disc of scutellum polished at 

 tip and its surface, otherwise, virtually impunctate ; propodeal sculpture not
