NOTES AND OBSERVATIONS^, 257 



ToETRix PRONUBANA IN LoNDON DISTRICT. — I havG to report the 

 capture yesterday of Tortrix pronuhana at Chiswick Park. To-day 

 I revisited the locahty to search for more, and took another within 

 about 500 yards of the first. There is a great deal of Euonymus in 

 neighbouring front gardens. — H. Douglas Smart ; A.Z. Ward, 4th 

 London General Hospital, S.E. 5, October 9th, 1917. 



SiREX GiGAs AND S. JuvENCus IN Eenprewshire. — Three speci- 

 mens of the former and one of the latter v^ere brought to me during 

 August of this year. I also heard of several other specimens of gigas 

 being taken in this neighbourhood. This is the first specimen of 

 juvencus taken here ; all were ? ?. T1\\q juvencus measured 2J in. 

 in expanse. — A. M. Stewart ; 38, Ferguslie, Paisley. 



LiBELLULA depressa, L. — Concerning Mr. C. Morley's request 



for particulars as to the occurrence of this species this year, it may 

 be of interest to know that 1 saw a specimen by the bank of the 

 Eiver Wey, near Godalming on June 17th. It is the only specimen 

 I have seen this year. — H. G. Q. Wales ; Gillwell Bury, Seward- 

 stone, Chingford, E. 4. 



Dragonflies in 1917. — I have bred this year Cordulegaster 

 annulatus (two <?, two ? ; nymphs from Angarrack, Cornwall), 

 ^Esdinia grandis, Cordulia anea (nymphs from Byfieet), Calo])teryx 

 splendens (rj and ? ; nymphs from Anningsley Park, near Chertsey), 

 Pyrrhosoma nymplmla (Angarrack, Cornwall), and Agrion puella 

 (Byfleet). Emergences this year were late. C. annulatus in 

 particular showed none of the usual signs of contemplated change 

 until quite late in June, and the last to emerge (a female) was as 

 late as July 26th. By the stream in Anningsley Park in June both 

 C. virgo and C. splendens were plentiful. This is the first time 

 I have seen these two species flying together. I could observe no 

 distinction in their habits or habitat. I have seen more Anax 

 imperator this summer than I liave for many years. In August 

 I saw it at Purton, near Swindon, and at Burley-in-Wharfedale, 

 Yorkshire, and in September by the Itchen, near Winchester. I did 

 not see this last one very clearly, but I have no doubt it was Anax 

 imperator, and it was interesting seeing them on Burley Moor again. 

 I had seen them in the same spot many yeai's ago, but though 

 I have been there many times since in the bright season for 

 them I had not seen them again until this year. It has seemed 

 to me for some time that this species is getting scarcer. Certainly 

 my impression is that as a boy I saw them much oftener than I 

 have in later years. I am very desirous of breeding A. imperator, 

 and should be very grateful to any one who could tell me of a likely 

 place to get the nymphs. — Harold Hodge ; 9, Highbury Place, N. 



DiPTERA ON Wareham Heath. — BomhyUus minor was not very 

 uncommon, fourteen $ and seven ^ being taken during three days 

 of rather rfeclement weather, August 7th-13th. One 9 was watched 

 ovipositing after the fashion of canescens, as described by Verrall, 

 and one pair taken in cop : on the wing. Anthrax fenestratiis seemed 

 nearly over, it had been plentiful in July; of A. circumdatus fourteen 

 specimens were taken and many more seen. These three species
