162 THE ENTOMOLOGIST. 



Fernald (126) has monographed the North American and 

 Antillean Chlorioninse — that is to say, the group formerly known 

 as Sphecinae, the latter name being now applied to the old 

 Ammophilinae. The external anatomy is discussed, followed by 

 analytical keys and descriptions of the genus Chlorion, its sub- 

 genera and species. 



Among the Khopalocera enumerated from Northern Canada 

 are Eiivanessa antwpa, Vanessa atalanta and cardui, Anosia 

 plexippus, and varieties of Papilio machaon, Pontia napi, and 

 Coenonympha tiphon (127). The Baron de Picquendaele (128) 

 briefly remarks on the larvae of several Micro-Lepidoptera found 

 in Belgium on the aspen. 



An up-to-date map of Cuba (129) has just been published. 



Muir (130) gives a brief account of a visit to the Viti Isles in 

 search of parasites, followed by anatomical and bionomical 

 notes on Stylopidse, with description of a new species of 

 Pipunculidse.

TORTRIX PRONUBANA, Hb., DOUBLE -BROODED IN 



BRITAIN. 



By Robert Adkin, F.E.S. 



From what I saw of the earlier stages of Tortrix pronuhana 

 last autumn, I was so convinced that an earlier emergence would 

 be found to take place that I determined to investigate the matter 

 at the earliest opportunity. This occurred at Whitsuntide, when 

 I was able to spend a few days at Eastbourne. A diligent search 

 of the Euonymus hedges produced a number of Tortrix larvae, 

 the bulk of them only too evidently not of the species sought ; 

 but among them were two or three suspiciously like those found 

 last autumn, and a pupa that was met with also looked likely in 

 general appearance, but instead of being between two leaves, as 

 was invariably the case with the autumn pupae, it was enclosed 

 in a single rolled leaf. However, the emergence from this pupa 

 of a fine male, and one example of each sex of the species having 

 resulted from the miscellaneous collection of larvae, has shown 

 clearly that there are at least two generations of Tortrix pronu- 

 hana in the course of the year in Britain.
