RECLASSIFICATION OF MICROGASTERINI 159 



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



Host : The original series was bred from a Phycitid larva. 



Apanteles isus sp. n. 



$. Very close to delrectans from which it differs as follows: 



Antenna a little longer and thicker, with the preapical segment not longer than wide. 



Mesoscutum more shiny, its punctation finer and more superficial and not closer along the 

 course of the notaulices ; in detrectans the punctation is crowded enough along the course of the 

 notaulices to form a band of duller sculpture. Disc of the scutellum polished, impunctate. 

 Metacarp between two and a half and two and a quarter times longer than its distance from the 

 apex of the radial cell. 



Ovipositor sheath one and one third times longer than the hind tibia. 



Europe : Hungary, Kiralyhalom, 2 $$, one the TYPE, 2 <$<$, bred 8.viii.i936 

 from Etiella zinckenella. 



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



Host : Etiella zinckenella Treitschke (Phycitidae). 



Except for the colour of the stigma and the almost colourless venation, this species 

 is also very closely related to mernla. In fact, the four species, merula, detrectans, 

 isus and mendoides form a small, compact group within the larger group, characterized 

 chiefly by the smooth looking propodeum with its percurrent keel and simple, gently 

 downcurved ovipositor. 



Apanteles merula Reinhard 



Apanteles merula Reinhard, 1880 : 366. 



$. Stigma evenly brown ; venation fully pigmented throughout. Hind tibia in greater part 

 yellowish but becoming infuscate towards apex. 



Face impunctate and with a satin-like sheen. Antenna a little shorter than the body, with the 

 two preapical segments almost square in outline ; unlike detrectans and isus, the pubescence of 

 the flagellum is more noticeable, somewhat bristly (Text-fig. 171). Distance between the 

 posterior ocelli equal to the distance between one of them and the eye-margin. 



Mesoscutum somewhat dull, finely, densely punctate with the punctures more crowded and 

 forming duller bands along the course of the notaulices ; in this respect, the sculpture of the 

 mesoscutum is unlike that of isus but differs from that of detrectans only in that the surface is 

 duller. Hind wing rather narrow ; cubitellan cell not higher than wide. 



Ovipositor sheath about as long as the hind tibia ; ovipositor with weak apical attenuation. 



Length: ca. 3-2 mm. without ovipositor. 



Europe. 



Type in the Zoologisches Museum der Universitat, Berlin. 



My interpretation of this species is based on a female in the British Museum (Nat. 

 Hist.), compared by Wilkinson with Reinhard's type. A. merula is largely charac- 

 terized by the sculpture of the mesoscutum.
