Eustmma silaceata, including ab. imulata, Haw. Mr. Prout mentioned 
that this latter species would feed up on fuchsia in captivity. 
Gonodontjs bidentata, etc.— Mr. V. Eric Shaw, dark forms of 
Gonodontis bidentata from Manchester ; also a cocoon of Plusia moneta, 
and ova of Edrop is punctularia and Anagoga pulveraria. 
Ova op Ccf.nocalpe vitalbata. —Mr. C. Nicholson, ova of Coenocalpe 
vitalbata. 
Note on Gonodontis bidentata, distribution. —Mr. J. W. Tutt 
observed that it was curious that so far as he could remember there 
were no specimens of Gonodontis bidentata of the dark form in any of 
the large collections, old or recent. This pointed to the probability 
that this form was a modern development, and it would be interesting 
to see if the normal colour of the thorax would be maintained in the 
future. Mr. G. H. Heath said this form of G. bidentata had, to his 
knowledge, been commonly met with in the Dewsbury district for 
several years past. 
Mf.lit.ea cinxia retarded by cold. —Mr. L. P. Prout remarked 
that owing to the unseasonable weather his brood of Melitaea cinxia 
had remained an abnormally long time, both in the last larval skin 
and in the pupal stage. The resulting imagines were all obviously 
weak, and many were crippled, but on the whole there was much 
variation. 
Pachys betularia paired with ab. doubledayaria. — Mr. C. 
Nicholson recorded the capture at Brentwood of a pair of Pachys 
betularia, in cop., the $ being of the ab. doubledayaria. 
July 1st, 1902.— Pachys betularia ab. doubledayaria. —Mr. J. A. 
Clark exhibited five specimens of Pachys betularia ab. doubledayaria, 
bred from York. 
Variation in Bankia aroentula. —Mr. G. H. Heath, a series of 
Bankia argentula from Chippenham Fen, the ground colour of the 
wing of some of the specimens being brick-red and of others grey- 
green ; some also showed considerable variation in the position and 
prominence of the stripe near the outer margin of forewing. 
Angerona prunaria Aberrations. —Mr. C. P. Pickett, bred speci¬ 
mens of Angerona prunaria, including a J specimen with the darker 
bands barely discernable. 
Statistics on Gonodontis bidentata.-— Mr. T. Hamling, a long 
series of Gonodontis bidentata, consisting mainly of the ab. nigra. The
