•connection w 7 ith the climatic conditions, indicate, though Glaznnow's 

 captures in May and June at Pendshakent, and the dates June 5th, in 

 Sarafschan, and June 11th and 19th, in Dschungaria, might admit of 

 a second brood, but in the Altai (the only definite date in which range 

 that we have found is Ongodai, July 10th) and to the north of Pekin, 

 where Herz states that it flies in June and July, it may be regarded as 

 almost certainly single-brooded. The nazira form in the north-west 

 Himalayas, and doubtless also in Persia, has at least two broods, for 

 there are several records for October, but we have no evidence as to 

 iihe date of its early emergences. Coming back to Syria our informa- 

 tion is on a very different scale, though we have no records, even from 

 the plains, earlier than May 10th, near Damascus, but by the end of 

 that month it has been taken, even up to 6,000ft., in the Lebanon and 

 Anti-Lebanon ; it occurs again at the beginning of July near Beirut, 

 and throughout the month in the mountains, and a third emergence 

 takes place, both in plain and mountains about the beginning of 

 September. In north-west Africa there seem to be but two broods, no 

 Tecord appears to be given of any autumn emergence. It is reported, 

 for example, from Biskra in February and May, and from Lambessa 

 and other localities in March and June. Meade- Waldo, to whom we 

 owe most of our information on this species in Morocco, states that it 

 only occurs there from April to July, there being two broods differing 

 somewhat in form. In Teneriffe Holt-White merely states that it 

 occurs from April till September, which may imply three broods, or 

 only two. The following dates have been collected from various sources 

 •and may serve to illustrate and supplement the above observations : —
