NOTES AND OBSERVATIONS. 255 



the minutest details with a series bred by myself from Genista at 

 Cambridge. The occurrence of this and some other European species 

 (as Carcina quercana) in British Columbia, and not in the Atlantic 

 States, is very interesting, and must indicate immigration by way of 

 Siberia. 



(2) Tortricodes fragariana^nsck is by no means correctly assigned 

 to Tortricodes ; it is in fact a Peronra, with veins 3 and 1 of hind wings 

 coincident — an unusual character, but not involving exclusion from the 

 genus. Hence the name fragariana cannot stand, since there is 

 already an earlier Peronea fragariana, Kearfott : I propose for the 

 species the name elajjsa nom. nov. — E. Meyeick ; Thornhanger,

Probable Danger of a New Pest. — I lately received from Paris 

 for determination an example of a small dark Tortrix which I 

 recognised as Laspeyresia molesta Busck, an insect native to Japan 

 and China, but accidentally introduced into the United States, whence 

 it was first described. The larva bores the fruit of the peach, and is 

 very destructive. M. Trouvelot, who communicated the speciYnen, 

 stated that it was bred at Erejus (Var), where it appeared suddenly 

 last year for the first time, a large proportion of the crop being 

 damaged. I am not aware that it has been found previously in 

 Europe. It seems to me so highly probable that this obnoxious 

 insect will be imported into this country in fruit or otherwise (since 

 it has already crossed both the Pacific and the Atlantic) that I think 

 fruit-growers would be well advised to look out for it, and report at 

 •once on its discovery. The larva attacks the twigs as well as the 

 fruit, and a description of its habits by A. L. Quaintance and W. B. 

 Wood will be found in the Journal of Agricultural Kesearch, vol. vii, 

 No. 8 (1916), issued by the Department of Agriculture at Washi .gton.

Colias croceus in N. Wales. — On August 19th a male of thi 

 species was taken, and two others seen at Rhyl, N. Wales. — W. 

 Bowater; 23, Highfield Road, Edgbaston, Birmingham. 



Comas croceus and Herse convolvuli i.\ Surrey. — Since 

 reporting croceus at Coulsdon on August 13th, I have made several 

 additional captures in the neighbourhood up to September 3rd. The 

 preponderance of males is rather striking, i.e. 13 out of 10. The 

 size of the specimens also seems much below the average. 



On September 29th I had brought to me a fine ? convolvuli 

 which had been captured at rest on a shed door at Old Lodge Lane, 

 Purley. Although taken the day previously it was in almost perfect 

 condition, which seems to point to the fact that it had emerged locally.

Herse convolvuli and Colias croceus at Wadhurst, Si ssex. 

 On October 3rd a tine female Herse convolvuli was brought to mo: it 

 had been found at rest in the town. 1 kept her f. i it failed to 



obtain any. Judging by the spring immigration of ( 'olias croceus, I 

 fully expected that 1922 would be an " edusa year," bul so far I have 

 taken but one specimen, a female, on September 7th. \\ adhu 

 under twenty miles from the coast and 1 was out collecting on most 

 sunny days.— A. H. Jones; Church Gate House, Wadhurst, Su
