of the three pupae, from which they issued Avlthout assistance, they made 

 a single small hole of rather irregular shape. In one case this is thoracic 

 and ventral in position, on the left side, piercing through the sheaths of 

 the imaginal legs. In the other two pupae the hole is ventro-lateral and 

 abdominal, immediately behind the wing-sheaths. 



The 43 specimens have been examined by Dr. Waterston and are 

 almost certainly all females : only in a few cases it is not possible to be 

 absolutely sure of the sex without floating the specimen off its card. 



Dr. Waterston has kindly supplied the following record : — In the 

 British Museum there is a 5 of Pt- deplanatus bred from the mine of 

 a Tineid moth in crab-apple at Fairhill, Tonbridge, Kent, in April 1917, 

 by P. A. Buxton. 



II. ICHNEUMONIDAE BRED FROM TORTRIX VIRIDANA. 



The three species of Ichneumonidae bred from other pupae of the 

 TorfrLv collected at the same time are : — 



(i) Fhaeogones siimuhdor Gravenliorst (Ichnemnoniiiae ; see Morley, Icliii. 

 Brit. I, p. 260). One S and five $ $, emerged 27-30.vi.l921. They were 

 named by comparison with the series arranged by Mr. Moiloy in the British 

 Museum, which includes a $ {ex Coll. Linn. Soc.) named by Gravenhorst. 

 My five $ 5 vary in length (excluding antennae) from about 5'5 to 8 mm. 

 The smallest $ , which emerged later than the rest, has the antennae abnor- 

 mally short, with much fewer segments tlian the normal ; the funicle is ratlier 

 a light ferruginous colour throughout, the whitish band, which in normal 

 specimens occupies about segments 9-11, not being distinguished from the 

 rest ; in this example also the abdomen does not seem to have attained its full 

 black coloration, hut is dark ferruginous, especially towards the apex. 



Morley {loe. cit.) states that this species is widely distributed on the 

 Continent, and has been frequently bred from pupae of Tortrix mridana. 



(ii) Pimpla brassicaviae Poda (Pimplinae : see Morley, op. cit. Ill, p. 109). 

 One small $, emerged between June 27th and 29th, 1921. Named by c.m- 

 parison with the series arranged by Mr. Morley in the British Museum, and 

 with specimens in the Cambridge Museum also named by him. This specimen 

 is referred to brassicariae mainly on account of the characteristic, markedly 

 canaliculate, form of the first segment of the gaster, and the absence of pale 

 vittae on the mesonotum. Its inner orbital margins are, however, narrowly 

 white, the apex of the scutollum and postscutellum are also white, and the 

 hind tibiae are pale-banded, in all of which features it inclines more to- 

 the closely-allied P. rufata Gmel. The British Museum contains specimens 

 of both these species named by Gravenhorst, and my example agrees with 

 Gravenhorst's si)ecimeu of brassicariae more closely than with his example 

 of rufata. 



Morley {loc. cit.) does not record P. brassicariae from Turtri.v viruJana, 

 though he does record P. rufata from that host.
