288 THE ENTOMOLOGIST. 
At the time I thought it was a battered specimen of V. wrtice, but — 
kept it, as it was the first I had seen that day, I believe, from read- 
ing South’s ‘The Butterflies of the British Isles,’ that it has not 
occurred in the Dover district since October, 1899.—H. F. Wimurams; 
Denstone College, Rocester, Staffs. \ 
DRAGONFLIES BRED IN 1916.—I have found this a bad year for 
breeding dragonflies. I think the coldness of June was unfavour- 
able to their emergence. It certainly made many species late. I 
have bred Brachytron pratense (one female; nymph from Byfleet, 
the first nymph of this species I have taken there); A/schna grandis 
(nymphs irom Byfleet); Cordulza enea (nymph from Horning, near 
Wroxham, Norfolk); Libellula depressa (nymph from West Corn- 
wall) ; Agrion puella. Four nymphs of Cordulegaster annulatus from 
Cornwall died on the verge of emergence. For a week or more one 
might say they were trying to come out, but were unable to bring 
off the great change. It was most unseasonably cold at the time 
(June), and I think that was fatal to them. Emergence demands a 
great physical effort, and in cold weather these nymphs (as a good 
many others, I believe) have not the strength needful. I have 
noticed for many years now a close correspondence between tempera- 
ture and successful emergence of dragonflies—Haronp Honae.

RECENT LITERATURE. j 
Yorkshire's Contribution to Science. By THomas SHepparp, M.Sc. 
5s. net. London: A. Brown & Sons, Ltd., 1916. — 
At the 53rd Annual Meeting of Yorkshire Naturalists at Leeds on 
December Sth, 1914, Mr. Sheppard delivered his presidential address 
on ‘ Yorkshire’s Contribution to Science.” This appears in the pages 
of the ‘ Naturalist’ for 1915, and the book before us treats the same 
subject more systematically and in much fuller detail than do the 
pages of the ‘Naturalist.’ The somewhat humorous address is 
followed by chapters on: Publications arranged topographically ; 
Existing Magazines and their Predecessors; Magazines now extinct ; 
County and Riding Societies; Yorkshire Topographical and other 
Magazines; Magazines generally; Scientific Societies; Geological j 
Publications ; Archeological and Antiquarian Publications; Books _ 
of Reference. The whole will be useful and interesting to any 
naturalist who is concerned with the literature of his subject. To a 
non-Yorkshireman the last five chapters will perhaps appeal most, as 
they are quite general and do not refer specially to Yorkshire. 
The illustrations of old title-pages, emblems, seals, etc., are very 
interesting.
