CAPTURKS AND FIELD REPORTS. 285 



were in the earliest stages yellowish, and none of the males had 

 developed the pruinose condition proper to the sex. The eyes of 

 fully matured males are remarkahle for their exquisite blue coloration, 

 but the eyes of the examples taken this year were, alike in both sexes, 

 chestnut-brown. L. sponsa was apparently not yet on the wing. 

 The following Agrionids were also collected (June 23rd to July 2nd) : — 

 Calopteryx splendens (in fine condition and unusually common, Hart- 

 ford) ; ErijOiromma naias (one female, Hartford) ; IscJinura elegans 

 (abundant, Hartford and Eamsey) with its female forms rnfescens 

 and infuscans ; Agrion puella (not common, Hartford and Eamsey) ; 

 and A. pulchellum (common, Hartford and Eamsey). A female of 

 C. splendens (July 2nd) was exceptionally large, measuring 47 mm. 

 in length and 69 mm. in alar expanse. — F. W. Campion ; 33, Maude

Lepidoptera from the Isle of Anglesey. — I understand that 

 very little is known of the Lepidoptera of Anglesey, and hope that 

 the following notes on collecting done on the north side of the 

 island during the months of April, August, and September may be 

 of interest. 



Taking the butterflies first, it may be noted that P. brassiccs and 

 P. napi are common everywhere, while P. rapcz is not so frequently 

 found. Specimens of E. cardaniines and C. edusa have been seen, 

 and some seasons P. cardui and P. atalanta are common. V. urticm 

 is always abundant, while V. io is only occasionally taken. The 

 Fritillaries are represented so far by single specimens of A. impliia, 

 A. aglaia, and A. adippe. On the moors and* heaths S. seviele is 

 abundant, while P. megcera, E. janira, E. tithonus, and C. pampliilus 

 are to be found everywhere. G. phlaas, L. astrarche, L. icarus, and 

 A. sylvamis are also obtained. The sallows, birches, and alders 

 growing on the heaths are very productive of larvae, the following 

 being found in greater or lesser abundance : S. populi, S. ocellatus, 

 C. furcula, D. viniila, P. dictceoides, N. ziczac, N. dromedarius, 

 L. camehna, N. cucullatella, A. leporina, S. libatrix, and A. betularia 

 (no example of var. doubled ay aria has yet been obtained) ; also 

 M. rubi, M. pisi, and A. myrtilli on the heather; D. capsincola 

 feeding on the seed-heads of Lychnis ; G. glaucata, B. bimaculata 

 (rare), and B. temerata (common), on hawthorn. (It may here be 

 mentioned that a curious variety of L. camelina emerged on March 

 29th, 1908, the right wings being of a pale buff colour, while those 

 on the left are the typical reddish brown.) On hazel the larvae of 

 P. bucephala are found in large numbers, while those of D. coryli, on 

 the same tree, are of rare occurrence. Larvae of D. pudibuiula, 

 P. siviilis, M. neustria, A. psi, and A. rumicis have also been 

 obtained. In the spring the sallow catkins are a great attraction to 

 P. rubricosa, T. gothica, T. stabilis, T. incerta, T. pulverulenta, 

 T. viunda (not very common), T. gracilis, X. areola (a curious chalky- 

 white form), together with 0. vaccinii, E. satellitia, X. socia (one 

 specimen), C. vetusta, and G. exoleta. At the same time of year 

 searching low plants at night produces larvae of N. triangulum, 

 N. baia, N. immulcB, N. rubi, N. xanthographa, T. comes, T. pronuba, 

 T. fimbria, E. lichenea (feeding on stonecrop on the sand-hills), and
