August, 1888.] 4.9 



A WEEK IN JERSEY. 

 BY E. C. R. JORDAN, M.D. 



From August 21st to August 28th, 1886, 1 was in Jersey, landing 

 on the morning of Saturday, August 21st, and leaving on the evening 

 of Saturday, August 28th. As the ground was new to me, I worked 

 hard in collecting both plants and insects ; the following species of 

 Lepidoptera were taken by me ; all, common and rare alike, are equally 

 recorded : — 



Pieris rapce. P. brassicce : a large number of the pupae of this insect were 

 found against the wall of a cabbage garden near St. Aubyn's, and though some were 

 affected by the usual parasite, a much greater number had fallen victims to a large 

 ichneumon, making its exit by a single round hole. 



Colias Edusa : not very common, but one or two seen e\erj day ; two caught. 



Polyommatus Phlceas. 



Lyccena Icarus : remarkably fine, and very variable, both in size and intensity 

 of colour. L. Medon. 



Vanessa urticcs : constantly on a large bush of red Valerian close to the house 

 where I was staying. V. Atalanta. 



EpinepTiele Janira : nearly over. E. Tithonus. 



Satyrus Semele : remarkably abundant, and varying much in size, but none large. 



Pararge Megcera. P. Algeria : abundant in the interior of the island, not seen 

 by the coast. 



Ccenonympha Pamphilits : abundant. 



The day before leaving the island I received from a botanical friend a letter of 

 introduction to M. Piquet, of St. Heliers, with the remark, " he knows every plant 

 in the islands ;" I found that he knew much about the insects also, and from him I 

 received Pieris Daplidice, $ $ , with the remark that it was not rare amongst 

 Reseda, and occurred twice in the year, May and August; also a pair of Argynnis 

 Lathonia, taken in the island, and also said not to be of rare occurrence. It would 

 be easy to point out deficiencies in my list, Pieris napi, Vanessa cardui and Io 

 must occur, but the record is of captures only ; of course, my attention was directed 

 towards any facts which might prove the truth of the late Mr. Wollaston's views 

 with regard to the size' of island insects, but the season was very dry, and this made 

 the observations non-reliable, certainly some specimens of unusually small size were 

 caught; for example, S. Semele, $ , expanse, 39 mm. ; the largest ever taken by 

 me being in the Visp Yalley : ? , exp., 62 mm. ; $ , 58 mm. 



Smerinthus populi : larva. 



Macroglossa stellatarum : imago seen, larva found. 



Zyga>na (sp. incerta) : empty cocoons were met with in two places, at Corbiercs, 

 and at St. Ouen. 



Here again M. Piquet gave me two specimens of Deilephila euphorbice reared 

 from larvae found on Euphorbia portlandica, near St. Ouen. I was not myself suc- 

 cessful in finding any, but only one short visit could be paid to the spot. 



Lithosia caniola : two specimens, at Corbieres, evidently attached to the lichens 

 on the rocks facing the sea. L. griseola : several, beaten from the cork elms on the 

 shore near St. Aubyn's ; the branches were covered with lichens.
