may have been due to some extent to the extremely lethargic nature 

 of the young larvte, which appear to keep to the spot on which they

Several members considered that the food-plants mentioned so 

 far were possibly only substitutes, and that the true food-plant had 

 yet to be discovered. 



The Rev. A. T. Stiflf exhibited— 



1. A series of aberrations of Kpinc/i/iele jurtina {janira), including 

 bipupillate specimens, females with yellow instead of orange round 

 the apical spots, very pale females, females with extra spots on the 

 undersides of the forewings, and a male with pale, indistinct bars 

 on the hindwings. This last is a particularly interesting specimen, 

 as the scales under the microscope show no sign of abortion or 

 ' bleaching,' but the bars are apparently genuine pale bars such as 

 are usual in the female, but generally hardly apparent in the male. 

 All are from Folkestone or Tavistock. 



2. A short series of An-tia villica, bred from Bentleet larvfe, show- 

 ing considerable variation. 



8. A pale, semi-transparent Hi/porrita jaci)b([<r, bred from a Tavis- 

 tock larva ; comparing in colour with the rest of the brood as 

 Zijijiina i>nri)uralis does with Z. trifolii. 



4. Three aberrations of Cfenonijmjiha jia)n}ihili(s. (a) A very large 

 femnle with black ocelli on the hindwings. Folkestone. (/;) Female 

 with double apical spot on the underside, (c) Male with minute, 

 but perfect, apical spot on underside. 



Mr. G. T. Porritt exhibited a very fine series of extreme forms of 

 Abraxas firoasidariata ab. nvjrosparnata, bred by himself from Hud- 

 dersfield wild larvae in 1916.

 pean butterflies presented to the Society by the widow of the late

Mr. S. G. Castle Russell exhibited — 



1. ApIuuitoiJKs Iii/iierantiis. A series of varieties, including ab. 

 cicca, ab. arete, and var. lanceolata, together with specimens with a 

 number of rings on upper hindwing, varying from one to three. All 

 the specimens with two exceptions were from North Hants. Mostly 

 bred from ova. 



2. A;iriailes coridnii. A male specimen showing unusually rich 

 colouring, Wilts ; a male specimen showing unusually pale colour-
