Thecla betuhe, L. — A good series fi'otn Essex, Glanvilles Woottoii, &c. 

 T. prniii, L. Sixteen fine examples from Monk's Wood. T. zv-album, Hubn. 

 One with the W mark at anal angle of hind-wings obliterated. T. qiiercus, L. 

 Two examples with the ocellus at anal angle of hind-wings without central 

 black dot. 



Thecla rtihi, L. — A ? in very fine condition, curiously bleached, the hind- 

 margins of all the wings quite pale brown. 



Chri/sophanus chrifseis^ F. — Three examples of this reputed British species, one 

 (J labelled " Woodside, Epping, from Stephens, fr. Dr. Leach" (J. C. D.). 



Chrysophanus virgaurese, L. — Represented by eight examples, mostly in only 

 fair condition. A rather worn ? , on an old-fashioned English pin which has been 

 cut off below the insect, is labelled " E. L. Capel-Cure on Cromer, Aug. 20, 1878, 

 see Entom., v. XIII, 45 " (C. W. D.). Five ^ specimens are labelled — " Mus. 

 Blom." (J. C. D.) ; " From Stephens " (J. C. D.) ; " Huntingdonshire, from 

 Dr. Leach," at side " Yaxley " ; " Griesbach Collection " (C. W. D.) ; " Ilaworth 

 Sale 1824 " (C. W. D.), the two latter being under-sides. Two ? 's also bear the 

 same label as the last mentioned, one having a label " Isle of Ely " at the side. 



Chrysophanus hippothoe, L. — Four examples ; one J in very bad order, and 

 one $ , rather better, are labelled " from Latham " (J. C. D.). A ^ has a large 

 triangular label with " Hippothoe " on one side, and on the other " Mus. Hawortli, 

 Faversham,Kent" (C.W.D.), and a <? under-side," Haworth's Sale, 1824" (C.W.D.). 



Chrysophanus dispar, Haw. — Tlie Dalean Collection contains one of the finest 

 series extant of this now extinct British butterfly, numbering 26 specimens, 11 of 

 which are ^ and 15 ? , one of the former and two of the latter sex being set to 

 show the under-side. They ai-c for the most part in excellent order, though a few 

 antennae ai'c broken. Unfortunately very few bear any data; a ? is labelled 

 " Whittlesea Mere, July, 1819," another (under-side) " Whittlesea Mere, July 8, 

 1833," and a third " Bred on June 23, 18il " (0. W. D.). Variation in size is very 

 considerable; the smallest <J (measured as set, with the wings only slightly sloping) 

 expands only 31 mm., and another is only a little larger, while the finest ^ is 52 mm. 

 in expanse. The smallest ? is 35 mm., and the largest 52 mm. across the wings. 

 Two ? 's ai'e much suffused with copper-red on the basal area of the hind-wings, 

 and another is much irrorated with black scales, and has the black spots very 

 large. The gem of the whole collection is an almost entirely black ? , the central 

 area of the fore-wings, to the end of the cell, suffused with copper-red, on which 

 the two basal black spots show up distinctly ; the transverse submarginal band of 

 black spots beiiig just visible, but almost lost in the black suffusion. Tiie hind- 

 wings and under-side of this magnificent aberration are nearly normal. It is 

 labelled "From Simmonds " (J. C. D.). 



Chrysophanus phlxas, L. — A large and very varied series, including a ver3' fine 

 example of the silvery ab. schmidtii, Gerh., " From W. & D., 1899 " (C. W. D.) ; 

 a S from Glanvilles Wootton has the right fore-wing, and a worn ? the left fore- 

 win", of the " schmidtii " colour. A very fine variety with the usual black spots 

 very faint, and the disc of fore-wings, and submarginal band of hind-wings, a 

 peculiar pale buff colour with only a slight coppery tint. A fine ? has the ground
