Messrs. Lockycr, Power, Richardson, and Shcarwood lent cases of brilliant 

 exotio Lepidoptera, while Mr. Jenncr Weir's case of insects of this order containing 

 specimens to illusti-atc " mimicry " excited great interest. 



There was also a remarkably fine collection of Coleoptera, exhibited by jilessrs. 

 Bryce, Bull, Champion, Marsh, and West. 



Several other orders of insects were represented, as follows : — Mr. Ilillman con- 

 tributed a case of galls, and a case of economic entomology, illustrating insects 

 injurious to vegetation ; while Mr. Marsh supplied IchneumonidcB, and Mr. Power 

 lent a case of anatomical dissections ; Mr. Bull showed Orthoptera, and Mr 

 McLaclilan kindly lent four cases of brilliant exotic Neuroptera. 



Microscopes added considerably to the extent of the exhibition. — J. P. B. 



NOTES ON BRITISH TORTRICES. 

 BY C. G. BAEEETT. 

 {continued from p. 156). 

 Since the notes upon Eupoecilia udana went to press, I liavo re- 

 ceived the following communication from M. E. L. Eagonot of Paris. 

 " M. Ferris has sent me several larva) (of tidanci) preserved in 

 " spirits of wine, from whicli I take the following description : Length, 

 " 8 mill. Bone colour or pale reddish-brown, the dorsal vessel darker, 

 " ordinary spots concolorous, small, raised, shining. Head : plates on 

 " the second and anal segments, and claspers, amber colour ; mouth 

 " and ocelli dark brown. Body cylindrical, attenuated at each extremity, 

 " living (as M. Ferris informs me) in the stems and petioles of the 

 " leaves of Alisma plantago, boring a gallery in the interior. It changes 

 " to a pupa in situ, after having spun a slight cocoon of grey silk." 



JEujxecilia Geyeriana, H.-S. — Hitherto mixed with udana, Gn., 

 under the name of f/riseana. A description will therefore be useful. 

 Alar exp., 5-G lines. 



Ilead and palpi ochreous. Antennae brown. Fore-wings shining pale yelloAvish- 

 ochrcous, with rich brown markings, consisting of an oblique streak near the base of 

 the dorsal margin, and a very oblique fascia in the middle of the wing, from tho 

 upper part of wliich a streak is given off which reaches the anal angle, thus fonning 

 a broad inverted Y, within which is a small dark brown triangle on tho dorsal 

 margin. There is also before tho hind margin a second fascia, ill-defined, but often 

 iiniling with tho posterior arm of the Y. Cilia ochreous, spotted with brown. 

 Ilind-wings grey with whitish cilia. 



Allied to udana, Gn., but with narrower and more shining fore- 

 wings, far more richly clouded with brown towards the apex. Allied 

 also to Mussehliana, Tr., which, however, has no well-defined fascise 

 as in this species.
