'CCURRENCE OF COLEOPHORA GLITZELLA, Hfmn., IN BRITAIN. 

 BY EUSTACE R. BA.NKES, M.A., F.E S. 



As it is high time that the occurrence of Goleopliora Oliizdla in 

 Britain should be chronicled, it may be useful to record the circum- 

 stances under which it was met with, and to give some details about 

 the species and its life-history. Larvae of a CoUophora were found on 

 Vaccinium ditis-idcea (cowberry) at E-annoch, in Perthshire, by Mr. 

 "W. Salvage in the spring of 1881, and again in 1891 and 1893, and 

 from some of these Mr. W. H. B. Fletcher had the pleasure of 

 breeding the imagines in those three years. On comparing them with 

 Mr. Stainton's continental specimens of C. Qlitzella, two of which 

 had been received from Herr Griitz, Messrs. Staintou and Fletcher 

 identified them as that species, and, were it uot needless, I could 

 confirm tlieir identification, having compared them and the larval cases 

 with Dr. O. Hofmann's original description (Stet. Ent. Zeit., 1869, pp. 

 119 — 122), as well as with the series of moths and cases in the Frey, 

 Stainton, and Zeller collections. In his exhaustive paper on the insect 

 {loc. cit.), for a translation of which f am indebted to the Rev. C. R. 

 Digby, Dr. Hofmann gives very full descriptions and details about its 

 life-history, but as these are too lengthy to quote, and Scotch examples 

 differ somewhat from continental ones, I append description.-? taken 

 from Rannoch specimens kindlj^ lent me by Mr. Fletcher. 



IMAGO. 



AntenncB white, sharply and rather broadly annulated to the tips witli blackisli- 

 brown ; basal joint much thickened with grey or pale greyish-ochreous scales. I'alpi 

 internally whitish or pale greyish-ochreous, externally much clouded with grey. 

 Head, thorax and tegula concolorous with the fore- wings. Fore-ioiiujs glossy, 

 unicolorous, varying in colour in different individuals from rather dark grey to pale 

 greyish-ochreous ; cilia pale grey to pale greyish-ochreous. Under-side grey to pale 

 grey, with pale grey to pale greyish-ochreous cilia. Exp. al., 12 — 14 mm. Hind- 

 wings glossy, dark grey to very pnle grey ; cilia pale grey to greyish-ochreous. 

 Under-side grey to pale grey, with pale grey to pale greyish-ochreous ciUa. Abdomen 

 dark grey to pale grey above, paler beneath ; anal tuft pale grey to pale oclireous. 

 Legs: anterior pair internally pale grey to pale oclireous, externally dark grey to 

 pale grey with the tarsal joints pale-ringed ; posterior pair internally pale greyish- 

 oclireous or pale ochreous, externally pale grey or greyish-ochreous, tarsal joints 

 pale-ringed. 



The females average smaller, paler, and brighter, i. e., less grey 

 and more strongly ochreous than the males. Scotch specimens seem, 

 as a rule, to run decidedly darker than those from the continent. 



LARVA. 

 Head black, highly polished, much narrower than prothoracic segment. Pro-
