ENIGMAS STILL UNANSWERED. 115 



by Herr Schmid, who proposes the name C. betulifolia 

 should the species prove distinct. 



31. "A Coleopho?'a larva, feeding on Vaccinium Myr- 

 tillus in a longish slender case, somewhat like that of Vimi- 

 netella" I have bred something from these apparently so 

 like Viminetella that I cannot distinguish it : moreover, we 

 know that that species feeds on Myrica gale, so that pos- 

 sibly it may also feed on the bilbery ; the point wants fur- 

 ther investigation. 



32. " A Coleophora larva, feeding on the seeds of Arte- 

 misia vulgaris at the end of September; the case shaped 

 like a withered flower." I have bred two of these, and they 

 appear identical with specimens taken in the perfect state, 

 amongst Artemisia vulgaris, between Bexley and Dartford 

 Heath some years ago. The species, however, if distinct, is 

 so closely allied to Argentula and Virgaureee, that, before 

 coming to a definite conclusion on the subject, I should like 

 to see a longer series than I at present possess. 



NEW ENIGMAS FOR SOLUTION. 



33. A brown Gelechia-like larva, found amongst moss 

 by Mr. Douglas last March. This may be G. terrella, for 

 whose apprehension a reward of ,£5 was unsuccessfully 

 offered two years ago. 



34. A Cemiostoma larva was found in August by Mr. 

 Wailes, mining in the leaves of Genista tinctoria ; from its 

 habit this cannot be C. Spartifoliella 9 and the mine is so
