Drj/afi pandora. Also typical ab. raledna, and one very dark one, 

 suffused with tawny. All were captured in the New Forest. Apokophyla 

 AusTRALis AB. iNGENUA. — Mr. Prout exhibited two specimens of this 

 aberration from Sandown, one taken in 1895 and one in 1896, and 

 drew attention to its great rarity, both here and on the Continent. 

 Mr. Tutt drew attention to the close superficial resemblance between 

 this aberration and Kpwida lutulenta. Dark abeiiratioxs of Tephrosia 

 BisTORTATA (crepuscularia). — Mr. Prout exhibited, on behalf of Major 

 Robertson, some dark aberrations of T. bistoi-tata, and one specimen of 

 the second brood, also one specimen of the extreme melanic form of 

 T. m-jimcularia, and drew attention to the fact that the dark 

 aberrations of T. bistortata always showed a strong broAvn tendency, 

 whilst those of the allied species, T. crepuscularia {biwulidaria) were 

 black. He also drew attention to the remarkable statement, made re- 

 cently by Mr. C. G. Barrett, that the second brood of T. butortata was 

 obviously T. crepuscularia. This view, he said, was quite untenable. 

 Mr. Tutt agreed Avith the remarks made by Mr. Prout, and described the 

 differences existing between the second brood of T. bistortata and 

 T. biundularia [crepuscularia). Although the ground colour of both 

 could be called " white," the dead-grey white (almost Avith a trace of 

 lead-colour in it) of the second brood of T. bistortata Avas very different 

 from the purer Avhite (or creamy Avhite) of the May- June species. 

 Zyg^.na caeniolica from Boukg d'Oisans. — Mr. Tutt exhibited 

 .^. crtrnwZiV-ft from Bourg d'Oisans, and read the folloAving notes: — 

 " The type of this beautiful species has the red spots of the anterior 

 wings surrounded Avith broad creamy-yelloAV rings, and the abdomen 

 has a red ring surrounding it, but the insect is so variable that many 

 aberrations have been named, a summary of Avhich may be found in 

 Notes on the Zipiaenidae. These Bourg d'Oisans specimens are 

 peculiar (1) in haA'ing scarcely any creamy rings to the red spots, and 

 (2) in having the bodies entirely black = ab. diniensis, H.-S. Sometimes 

 the first character is carried to the extreme, and no creamy rings are 

 present at all. This form is the ab. berolinensis of Staudinger. A 

 combination of these two aberrations comprise almost 90 per cent, of 

 the sum total of the specimens of this species observed at Bourg d'Oisans. 

 I would also call attention to the union of the central and basal pairs 

 of spots in many specimens." Caksia paludata ab. imbutata and 

 Melanippe montanata. — Mr. Oldham exhibited Carsia paludata 

 ab. imbutata, from Manchester Mosses, and remarked on the gradual 

 restriction of the mosses by drainage and cultivation. The Melanippe 

 montanata Avere from Cambridgeshire, and some were very Avhite, Avitn 

 very distinct bands. TRiPH.^iNA fimbria ab. virescens. — Mr. Heasler 

 exhibited a specimen of T. fimbria ab. rirescens, Tutt, from Wimbledon. 

 In the NeAV Forest, he said, it Avas generally looked upon as being 

 very rare. Mr. Tutt thought it Avas a generally distributed form. 

 Variation of Eupithecia sobkinata. — Mr. Tutt exhibited a picked 

 series of Eupithecia sobrinata, captured by Mr. and Mrs*. Tunaley, at 

 Aviemore. He said he believed the Scotch race as a Avhole 

 was named var. scotica, by Dr. F. B. White, but the name Avas 

 generally restricted to the pale variegated forms, Avhich did not appear 

 to occur in the South of England. The series shoAved that there Avas 

 considerable variation among the Scotch specimens, the indi- 

 viduals arranging themselves into tAvo parallel groups, one 

 running through a series of broAvn forms, until the species
