OCCUEEENCE IN ENGLAND OF COLEOPHORA TRIGEMINELLA, 



FucHS, A SPECIES NEW TO THE BEITISH LIST, WITH 

 NOTES ON C. KRONEELLA, Fuchs, AND C. BADIIPENNELLA, Dup. 



BY EUSTACE R. BANKES, M.A., F.E.S.** 



Ill 1907, my friend, Mr. Alfred Sich, forwarded for identification 

 two out of five examples of a Coleophora which he had bred, in June 

 1906, from larvae found on hawthorn, during the preceding month, at 

 Brentford, Middlesex,* and Putney, Surrey, and had failed to reconcile 

 with any British or Continental species. He remarked that the imago 

 was " smaller and greyer " than the elm-eating Coleophora known to 

 him as badiijjennella, and that the lan^al case, of which two specimens 

 accompanied the moths, had " three keels at the posterior end and 

 consequently three valves," whereas the short dark case of badii- 

 pennella only possessed two valves. The insect in question was clearly 

 not identical with any in the British List, and was unknown to 

 me, but, on my referring to Fuchs' notice in Stett. Ent. Zeit., 1881, 

 pp. 462-463, it seemed evident that it was trigeminella, Fuchs. This 

 determination was confirmed by a comparison with the solitary ex- 

 ponent, accompanied by the larval case, of trigeminella in the Frey 

 Collection — this is labelled in Frey's handwriting, " C. trigeminella, 

 Fuchs. Bornich." The locality specified leaves little doubt that 

 the specimen was received from Fuchs himself, for his paper contain- 

 ing the notes on trigeminella is headed " Microlepidopteren des 

 Eheingaues von Pfarrer A. Fuchs in Bornich." In the course of his 

 lengthy notice (I.e.) of " Coleophora trigeminella, n. sp.," Fuchs stated 

 that he was acquainted with the true hadiipennella upon sloe, but had 

 only met with trigeminella on two young cherry trees in the Eheiugau, 

 though it occurred in abundance on them — the moths emerged in 

 June and July from larvae collected off the stems and branches of 

 these two young cherry trees in late May and early June, but the 

 older trees were searched in vain. No cases were discovered on the 

 young foliage, and the larvae were never found feeding, though 

 presumably they had fed upon cherry. Fuchs added that a descrip- 

 tion of the imago was needless, for it precisely resembled hadiipennella, 

 Dup., but that, whereas the case of the latter is two-valved, the more 

 slim and cylindrical case of trigeminella, which is yellowish brown or 

 reddish brown in colour, is three- valved, and is also longer, measuring 

 2j Paris lines [= 5-06 mm. E.R.B.]. C trigeminella, which is appar- 

 ently scarce with us, has long remained unrecognised in this country, 



* A second Middlesex locality for the insect is Chiswick, where Mr. Sich found two casea last 

 Spring.— E.R.B., ix, 1910.
