two new species of Nematus, — N. flavipennis and N. baccarum, 

 Cam, ; the latter probably the smallest species of this genus, and 

 bred from hairy pea-shaped galls sent from Dunkeld by Dr 

 Buchanan White ; an Eriocampa, reared from yellow larvae, 

 feeding on the upper surface of rose leaves, which is either a new 

 species or the true Tenthredo aethiops of Fabricius, and appears to 

 be quite unknown on the Continent. Of Ichneumonidae, a 

 new species of Bassus, bred from the larvae of Nematus cad- 

 derensis, Cam.; a species of Ichneutes, bred from the larvae of 

 Nematus viminalis; a specimen of Ichneutes reunitor, reared from 

 the larvae of Cladius padi, and the male of the rare Eumeslus 

 crassicornis, from Kingussie. This is the first indication of the 

 life history of Ichneutes, and as there are only four species, it is 

 probable that they are all attached as parasites to the Tenthre- 

 dinidae. Both the species of Ichneutes, as well as the Bassus, 

 were found in Cadder Wilderness. Mr Cameron also enumerated 

 several other interesting species from stations in the neighbour- 

 hood, and showed the cast-off skins of the larvae of Phaenusa 

 pygmaea, retaining completely their forms and markings, a very 

 unusual occurrence with larvae of saw-flies, and perhaps in this 

 instance owing to disease, as the larvae died shortly after 

 moultinsr.

Peter Cameron. 



In continuation of my paper on the British leaf-mining saw- 

 flies. Vol. ii., pp. 315-321, I propose here to monograph the more 

 obscure and perplexing species of Phaenusa. The species belong- 

 ing to this genus are amongst the smallest of the family ; they 

 have short thick bodies, generally of a deep black colour, with the 

 feet more or less relieved with testaceous or white. The antennae 

 are 9-jointed (in P. hortulana according to Hartig they are 

 apparently 10-jointed); the maxillary palpi 7-jointed; the eyes 

 touch the base of the mandibles; the wines have 2 marginal and 

 3 sub-marginal cellules, the first and second of the latter receiving 

 each a recurrent nervure : the lanceolate cellule is petiolate; the 

 posterior wings have no middle cellule; and the feet have no 

 patellae. The larvae resemble those of Phyllotoma, and the 

 ^description given at pages 315, 31 G {I.e.) will appb^ here, the only
