(iii) Lahrorhychus nigricornis Wesmael (Opliioninae : spe Morley, o/?, cit. 

 V. p. 247). One c?, emerj^ed between June 27th and 29th, 1921. Determined 

 by comparison with examples in the Cambridge Museum which were named by 

 Mr. Morley : apparently quite- typical. Not recorded by Morley as bred from 

 Tortrix viridana. 



The eight pupae from which these Ichneumonids emerged were all 

 found in the breeding- vessel. None are quite the full length and several 

 are very small and short, one which is only 6 mm. long being the tiniest 

 of all the pupae collected. All the Ichneumonids emerged at the head 

 end. In two cases the head end is entirely gone, a jagged edge being 

 left all round. In a third, not only the part forming the sheath of the 

 imaginal head, hut also all the part covering the antennae and legs, has 

 broken neatly away, leaving a wide opening between the wing-sheaths. 

 In the remaining five pupae there is a rather small and \erj in-egular 

 opening, antero-ventral, just behind the imaginal eyes and in the region 

 of the mouth-parts. 



In addition to the above three species, the following list of 

 Ichneumonids recorded from Tortrix viridana has been compiled from 

 Morley's " Ichneumonologia Britannica," Vols. I-V. The volume- and 

 page-references are to that work. Several of these species are, however, 

 only recorded therein as having been bred from this host on the Continent, 

 not in England : —

III. OTHER ENEMIES OF TORTRIX VIRIDAXA. 

 My observations under this head are very slight. 



(i) Calopteryx virgo. On June 21st, 1921, by one of the streams at 

 Queen's Bower, New Forest, a J dragonfly of this species was seen fluttering 

 a few feet above the ground and carrying a specimen of the Tortrix. On being- 

 approached it dropped the moth, which seemed to be dead. 



(ii) Empidae, sp. On the preceding day, June 20th, in New Park 

 Enclosure (Brockenhurst), at about 9 p.m. (summer time), a large reddish- 

 brown fly was noticed carrying a specimen of the Tortrix. The fly was 

 probablj"^ Empis livida (see below), though in the failing light it could not be 

 very clearly seen and I was unable to catch it. It dropped the moth, which 

 in this case also appeared to be quite dead.
