 This species varies in having the sides of the abdomen and the belly 

 more or less of a testaceous colour.

Not common. Imago early in June. Larva at end of July and in 

 August, on Salix aurita, S. caprea, etc.

 Rannoch. 



3. T. BETULETI, Kl.

 on Crataegus.

4. T. soRBi, Htg. 



Rare. Imago in June. Larva in August and beginning of July, on 

 Pyrus aucuparia. 

 Strath-Glass, Rannoch, Braemar. 



ABIIDES. 



ABIA, Leach. 

 1. A. SERICEA, L. 



Very common. Imago in June. Larva in August and September, on 

 Scahiosa succisa. 



Possil Marsh, Clober, Paisley, Bishopton, Glenelg. 



Rannoch, Braemar, Kingussie, Strath-Glass, Bonar Bridge. 



Obs. Thomson (Hymen. Scand. i., 27) has adopted the name of niteiis 

 for this insect, which, according to him, is the male of L. sericea. Zad- 

 dach, on the other hand, retains the name of sericea for it, and applies 

 nitens to another species — A. sjjlcndida, Kl. = hrevicornis, Leach. Liune's 

 description is ambiguous; but I scarcely think that he had splcndida in 

 view, because that insect is very rare, and is not, so for as I can ascertain 

 (beyond the doubtful description of Linne's), a native of Sweden ; is 

 certainly a southern insect.
