"Milliere (lonographie et Description de Chenilles et Lepi- 

 doptera, 1869) figures as two vars. oi iinmanata, two forms of 

 truncata, thus his varieties of C. russata on pi. 5 are forms of 

 immanata, fig. 11 being a well marked typical form, and fig. 

 12 the var. tJiingvallata, Staud. Then again — 



Plate iii. fig. 7, immanata var, = perfiiscata, Haw. 

 „ „ 8, immanata var. = comma-notata, Haw. 



"The specimen which Stephens describes and Wood figures 

 as ainoenata, was taken in Devonshire, but I have nothing 

 among my Devonshire examples which agrees with either 

 description or figure. It is certainly a modification of the 

 marmorata form of imvianata. The only insect I possess at 

 all like amoenata is one from Lewis, which you will find num- 

 bered 3 in the series from the Hebrides. 



" TJiingvallata, which has white primaries with black basal 

 patch and central fascia, is a modification of the type form. 

 I have no example of it, nor have I seen a British example; 

 but Mr. Leech has specimens from Japan, and I have seen 

 Dr. Staudinger's specimens from Iceland. The upper speci- 

 men of the two from York varies in the direction of tJiing- 

 vallata. 



"The unicolorata form of Staudinger appears to be somewhat 

 protean in character, as it may be ashy-white, fuscous, 

 ochreous, or blackish. Milliere figures (Icon., pi. v., fig. 10) 

 a curious looking aberration which Dr. Staudinger includes 

 with unicolorata, but I can make nothing of it ; the markings 

 are those of immanata in character, but they are pale olive- 

 green in colour. 



" The thirteen specimens from the mainland of Shetland are 

 of an almost unicolorous form, but those fromi Unst are neither 

 good immanata nor marmorata, though possessing the cha- 

 racters of both. I believe that this Shetland form is immanata 

 var. pytJionissata (Milliere, Icon., plate iii., fig. 9). Some of 

 my specimens from Unst agree well with this figure, which I 

 may add represents one of three specimens sent to Milliere by 

 Doubleday, who bred them from larvae." 



Mr. E. Step exhibited Testacella Jialiotidea, Drap., from 

 Lewisham, and Helix lapicida, L., from Langley Bottom, 

 Epsom.
