etc., the cases found would^liave been much cleaner in colour, 

 not having been subjected to the muddy water. 



"C.laricella. — Several imagines, bred from the larvai exhibited 

 at the June meeting, are shown, together with a tuft of larch 

 needles mounted to show (1) the depredations of the larvaj, 

 (2) the hybernating case of the young larva {in sitto), (3) the 

 position of the larva and its case when feeding, and (4) the 

 position of the case fixed at the base of the needles in the 

 middle of the cluster dui'ing change of skin or for pupation. 

 On the same mount are placed (1) a pupa to show the peculiar 

 lengthening of the wing, antennae, and leg-sheaths beyond the 

 abdomen, a character common to all the members of the genus, 

 (2) a case on a larch needle to show the obliquity of the mouth 

 opening, and (3) cases to show the vmusual method of making 

 addition to the length and size, by which what was at first the 

 back of the case becomes after the enlargement the under-side, 

 and the mouth opening has its obliquity reversed. At the June 

 meeting I exhibited the ova of this species, which had just 

 been deposited. I passed these on to Dr. Chapman, and he 

 has since described them ; and Mr. Noad Clark, of Paddington 

 Infirmai-y, has made some admirable photographs of them, 

 which I now exhibit. (1) Four ova placed together, showing 

 them to be ' upright ' eggs, micropyle at the top, with only 

 two diameters, and vertically ribbed, simulating at the first 

 glance typical Noctuid eggs. These are magnified twenty 

 diameters. (2) Two photographs of the crushed egg, to show 

 the peculiar minute papillje with which the whole surface is 

 closely covered, and the arrangement of the micropylar cells. 

 Magnified one hundred diameters. 



" C. vibicella. — Imagines and cases of a rather local species, 

 which, although generally distributed on the Continent, has 

 only been recorded from a few English localities. Those 

 exhibited came from Trench Wood, Worcester, and were 

 taken about the year 1886." 



Dr. T. A. Chapman remarked that the curious papillse on the 

 surface of the ova of C. laricella showed that they weie in no 

 way related to the Noctuid group, and he considered that the 

 " upright " form had arisen from quite another line of develop- 

 ment. Commander J. J. Walker said that he had met with
