Var. of Smerinthus TitiJE. — I bred a fine female .S". ti/ics to-day, 

 with black hind wings. J. A. Clark, /loie 5M, 1890. 



Sexual Variation in Euchelia jacob^^.— I do not remember 

 having seen it remarked that there is a distinct difference in the colour, 

 or shade of colour, of the males and females oi Euchelia jacobcca. It is 

 well known that, contrary to what is usually the case, the males of this 

 moth are considerably larger than the females ; but this is not the sole 

 distinction. The moth, generally abundant, has this year been more 

 than ordinarily so, and, sorting out a long series, I was struck with the 

 difference of colour between the sexes. The fore-wings in both sexes 

 have the brilliant carmine identical. In the females the hind-wings 

 are of the same bright colour ; but the hind-wings of the males are 

 much lighter — in fact, are not carmine, but crimson. The moths first 

 made their appearance this year in the latter half of May, and are to be 

 taken now in the middle of July. A good instance of protective resem- 

 blance afforded by this moth was noticed by Mr. Dover Edgell at 

 Bognor. A specimen at rest on a dark red brick wall assimilated in 

 tints so wonderfully to its surroundings as to be barely perceptible. My 

 largest male measures exactly if in., my smallest female i^in. A large 

 number of the larvae were collected and bred by Mr. Edgell in the hope 

 of obtaining a yellow variety ; but they were all of the normal colours. 

 I saw some years since a remarkable variety in the cabinet of Mr. 

 Cabris of Ringwood, in which the hind-wings were of the same smoky 

 colour as the ground colour of the fore-wings, being destitute of carmine 

 or crimson altogether. — Joseph Anderson, Jun., Chichester. 



Small Variety of Euchloe cardamines. — In reply to Mr. A. E. 

 Hall (Etit. Record^ p. 98), I may say that I have a male specimen of 

 E. cardamines, which I took here a few years ago, measuring one 

 inch and three-eighths from tip to tip, very little larger than his. My 

 largest male is nearly two inches. — Id. July, 1890. 



Small Varieties of Smerinthus populi. — I possess two males of 

 this species which, I believe to be unusually small. One measures 

 exactly two inches and an eighth from tip to tip, while the other is 

 scarcely a quarter of an inch larger. They were both bred from 

 larvae in 1888. — J. H. D. Beales, Arthur House, Margate. July, 1890.

 tious food. — Ed.] 



Local Forms of Ccenonympha davus. — Cceuofiympha davus from 

 Manchester mosses are dark, darker than Hartford specimens I have, 

 and apparently darker than the typical C. davus at Kirkby. — 

 J. Collins, Warrington. August iT,th, 1890. 



Smerinthus tili^ var. — I have this year bred a variety of S. tilia:, 

 in which all the wings are of a beautiful fawn colour similar to the 

 ground colour of the normal type, but much brighter, the hind wings 

 being especially so. The green tint is scarcely visible, and even the 

 dark central band of the fore wings is suffused with the red tinge. 

 Thorax and body are of the same colour. This specimen was bred 

 from a pupa found under the bark of elm. Last year I bred a variety
