a lot of ova, all of which look fertile, the $ was a cripple. I 

 also paired a $ of A with a ^ bred from a larva beaten in the 

 New Forest last year ; very few ova were laid and none of 

 them looked fertile. It will be seen that brood B seems more prolific 

 of fertile eggs then the other three, probably this is owing to the 

 parents of this brood having been of different stocks. It is also 

 remarkable that both the crippled $ s of brood I (one of which was 

 paired with a 3^ of the same strain, and the other with a <? of brood 

 A), produced fair-sized batches of apparently fertile ova, while well 

 developed $ 's of the same stock laid few if any fertile ova. I found 

 much greater difficulty in pairing dark moths with dark moths than in 

 crossing light with light or light with dark, and this quite irrespective 

 of their being of the same or different broods." Mr. Bayne exhibited 

 the following aberrations : I'oh/owwatm icani^^ : males of the following 

 forms- (1) Lilac blue. (2) Bright blue. (3) Bright dark blue. (4) With 

 slight trace of black spots on hind margins of wings. Cnenonijinpha 

 pamphilm : (1) Pale form from Aylesbury. (2) Dark form from New 

 Forest. Fleheim aeijon (undersides) from the New Forest : (1) With 

 slightly coalescing spots. (2) With spots on hind-wings forming a 

 short band. (3) With the last pair of spots on fore-wings wanting. 

 Also specimens oi Polyommatm asitrarchc and P. icarua, showing parallel 

 aberration to the P. cn'i/on marked 3 above. Hyhernia dcfuliaria : 

 (1) With strong melanic tendency. (2) Dark unicolorous form. (3) 

 With band continued across the hind-wings. (4) Two forms of the 

 female — ^typical and melanic. Mr. May recorded a specimen of 

 r/iii/alia pcdaria, seen on a lamp at Tooting, on -January 26th last. 



The Entomological Society of London held a meeting on 

 February 5th, 1896. Mr. Waterhouse exhibited pupje and portions of 

 pupiB of a silk moth, Antheraea iiujlitta, selected from some scores of 

 specimens, which he had opened to see if they showed stages of develop- 

 ment agreeing with the examples given by Dr. Spiiler. The results 

 appeared to confirm Dr. Spiiler's researches ; some specimens showed 

 the trachea", the median vein having two branches, very rarely emit- 

 ting a third branch in the direction of the radial. Other specimens had 

 faint indications of the veins and of the discoidal spot of the imago. 

 Even at this very early stage the vein branching from the subcostal 

 vein to unite with the upper radial, and the short branch uniting the 

 second median vein with the third median were distinctly traceable, 

 no trachete being yet visible in these branches. Mr. E. E. Green 

 remarked that in the Tranx. Ent. Soc. Loud,, 1881, p. 601, there was 

 a short paper by the late Prof. J. 0. Westwood, describing a curious 

 little insect from Ceylon, under the name of Di/scritina loju/isi'tosa. 

 Prof. Westwood believed his typical specimens to be immature, 

 Mr. Green exhibited what he supposed to be a later stage of the same 

 species. He said his example dift'ered in some particulars from 

 Westwood's description and figure — notably in the proportions of the 

 caudal appendages. Prof. Westwood pointed out the affinities of 

 iJi/srritina to the Forricnlidar. This was very apparent in the 

 specimen under consideration. Putting aside the nature of the caudal 

 appendages, the insect was in all particulars an earwig. The present 

 specimen was taken in the Punduloya district of Ceylon, at an 

 elevation of about 4,000 feet. Mr. Green said he had more than once 

 seen this insect under loose pieces of bark and in crevices of rocks, and 

 had always been struck by its likeness to an earwig, both in appearance
