220 THE entomologist's record. 



from l^/ic in. to l^/ie in., (tU have the discoidal spot placed at the 

 juncture of the white and orange. The females of this latter, of which 

 I have four specimens, resemble small females of E. cardamines ; mine 

 vary from P/ie-in. to l^/ie-in. Both sexes appear much more slender 

 than E. cardamines, even allowing for difference of size. Under a 

 powerful microscoj^e, the plumules of E. hesperidis are narrower and 

 proportionately much longer than those of E. cardamines, while the 

 whole appearance of the wing is much more even and not nearly so 

 rough as is the case in the latter species. Among those species of the 

 genus Eucidoe, in which the males, at least, are tipped with orange, 

 cardamines and damone have the discoidal spot placed within the orange 

 tip, while in gnmeri, eupheno {euphenoides) and douri {eupheno), the 

 discoidal spot is situated at the juncture of the yellow and orange. I 

 regret to say that I have been unable to get any larvas of E. cardamines — 

 far less of E. hesperidis — though I have both searched and swept for 

 them in localities in which the former are usually abundant. I quite 

 agree with Dr. Buckell, that it would be a very good tiling to obtain, 

 if possible, the larvee of E. hesperidis, but I emphatically differ from 

 him when he seems to infer that without this knowledge the differenti- 

 ation of species is imj^jossible. Every entomologist must be aware, that 

 even now there are many Avell-established species, whose larv^ are as 

 yet unknown, but which nevertheless are distinct species. In thej)ast, 

 this was the case in very many more instances, but how often did the 

 subsequent discovery of the la'rva tend only to ratify the prior suppo- 

 sition ! Before finally coming to a conclusion on this j)oint, it would 

 be well to compare as many species of the genus Euchloc as possible, as 

 some of them will be found to offer differences which are but slight, at 

 least to the uninitiated. — F. B. Newnham, Church Stretton, Salop.

Sariation. 



A RARE FORM OF THE LARVA OF AcHERONTIA ATROPOS. On AugUSt 



11th, 181)4, Mr. Lewcock found in my garden here two larvse of this 

 species, one of which was a full-grown si^ecimen of the very rare dark 

 olive-red variety, mentioned by Stainton (Man., vol. i., p. 89). The 

 following description of it may be of interest. General colour : dull 

 reddish-brown. Face : pale, with three tine black lines on each side of 

 the anterior surface ; these incline towards the centre, Avhere the inner- 

 most pair meet. Body: the first three segments whiiish, but much 

 mottled with reddish-brown at the sides, and with a fine jjale dorsal 

 line, which passes through the very dark brown, well-defined, sub- 

 dorsal area ; the remaining segments reddish-brown, and marked on the 

 upper surface with rounded whitish spots, in place of the black spots of 

 the normal larva. The stripes, which in the ordinary form are yellow 

 and violet, are here replaced by dark, almost black, broadish crossed 

 lines, which form a regular series of St. Andrew's crosses, the widest 

 part being at the junction of the segments. These dark crossed lines 

 appear to replace tliose which are usually violet, which latter, however, 

 do not cross, but end in a point at the back of each segment. Tail : 

 black, with whitish nodules. Spiracles : deep black, circular. Legs, 

 and proieijs: ])laekish-brown. — (liev.) C li. N. Burrows, Eainham, 

 Essex. August 14//<, 1894.
