30 ADDITION A J. ALDERNEY INSECTS. 



I have to thank Dr. Walker for specimens of two rare 

 species of Dragon Flies, namely, Sympetrum Jlaveolum, L., 

 and Lestes Barbara, Fab. Both these insects were taken in 

 considerable numbers near the pond on Longy Common. 



8. jlaveolum has been taken by myself in Guernsey, but 

 is rare in England. One specimen captured by Dr. Walker 

 is an unusual variety, and is described by Mr. R. McLachlan 

 in the Entomologists' Monthly Magazine, September, 1900. 

 He says : — " At first sight I thought it might be fonscolombi, 

 but it is really Jlaveolum, with the yellow on the wings reduced 

 to a minimum. Parallel varieties of Jlaveolum are not un- 

 known, but are certainly rare (or confused with other species); 

 on this point see De Sely's ' Revue des Odonates,' where (at 

 pp. 34-35) allusion is made to similar individuals from Belgium 

 and Prussia." 



Lestes Barbara, was for a long time on the British list on 

 the authority of one example in the Dublin Museum, said to 

 have been taken in Ireland. Mr. McLachlan says it is dis- 

 tinctly Mediterranean in its habits, but is abundant near Paris. 



One specimen of the large Dragon Fly, jEschna mixta, 

 was taken by Mr. N. W. Gaudion and sent to Dr. Walker. 

 It has been taken in Guernsey and Sark, but is a rare and 

 local species in England, being confined to the south-eastern 

 counties, and but few captures have been recorded. 



The Hymenoptera have been submitted to Mr. E. 

 Saunders for naming, with the result that there are nine 

 additions to the list. Unless otherwise stated the insects on 

 the following list were taken by Dr. Walker during this 

 season. 



ADDITIONS TO THE ALDERNEY LIST. 



LEPIDOPTERA. 



RHOPALOCERA (Butterflies). 



PieriS napi, L. Taken by Mr. L. Langlois. 



Colias hyale, L. One specimen seen by Mr. E. D. Marquand. 



Argynis aglaia, L. Taken by Mr. L. Langlois. It is not uncommon 

 in Sark, but has not been taken in Guernsey. 



A. paphia, L. Taken by Mr. Langlois. Probably a visitor from the oppo- 

 site coast of France. 



Vanessa polyehloros, L. One fine fresh specimen seen by Mr. E. D. 

 Marquand on July 24th. 



Pararge egferia, L. Several specimens captured by Mr. Langlois. 



Epinephele tithonus, L. Taken by Mr. Langlois. 



Ccenonympha pamphilUS, L. One specimen taken by Dr. Walker, 1900. 



Theela quereus, L. Taken by Mr. Langlois. An insect we would hardly 

 expect to find, in Alderney ; the larva feeding on oak. Probably an 

 accidental visitor.
