while the terebra is shorter than the abdomen. Also resembles 

 ohsairelliis, though, of course, considerably smaller and having 

 the third abdominal segment more shining. 



I have come across very few examples ; one female from the 

 Gog Magog Hills, Cambridge, May 20th, 1917, another from a 

 shady lane at Hunstanton, June 4th, 1918, and a third taken on 

 young beeches growing on a heath at Snettisham, Norfolk, 

 July 15th, 1919, are the only specimens I possess. 



Obscurellns, Nees.* 



This is not the obscurellns of Haliday.f which is proved by 

 Marshall to be a synonym oifloricola, Wesm. (see ' Trans. Entom. 

 Soc.,' 1885, p. 108). 



A robust species measuring 5-6 mm. in length, with the third 

 abdominal segment entirely and noticeably simulose and terebra 

 equal in length to the abdomen. Bignell reared it from larvae 

 of Gymnetron noctis, and in September, 1918, Dr. E. A. 

 Cockayne sent me twenty-two bred from the same host, which he 

 found commonly at Limber, North Lines., feeding on toadflax. 



BUTTEEFLIES IN MACEDONIA. 

 By Herbert Mace. 



(Continued from p. 42.) 



P. machaon. — A very common butterfly wherever I happened 

 to go during the summer months. In September, 1917, it simply 

 swarmed on a dry hillside near Janes. It appeared to be attracted 

 by a very tough species of umbelliferous plant which is notable 

 for remaining brilliantly green while all the surrounding herbage 

 is dried up ; and on this plant the larvae were present in all 

 stages. Machaon is more subject to variation than is commonly 

 noted, and my Macedonian specimens differ from those found in 

 our fens. The ground-colour is paler and clearer yellow, and the 

 scales on the nervures of the fore wings are much less thickly 

 placed, the nervures, in fact, being almost thin clean lines. The 

 black markings in general are much paler, and the submarginal 

 band is noticeably narrower throughout. In several specimens 

 the blue lunules are larger and brighter than in British speci- 

 mens, and one or two have the first and second yellow lunules 

 on the hind wings filled in with deep orange. I took one female 

 of exceptional size, being 4| in. across the wings, and the 

 general appearance is much more bold than the usual type. It 

 was on the wing from the beginning of April to the end of
