110 LEPIDOPTERA. 



closed b}^ a silky suture. I find these cases in May on the 

 trunks of beech trees, which I suppose they ascend in the 

 evening, remaining concealed during the day amongst the 

 withered leaves. I have reared them by feeding them with 

 beech leaves and lichens, but I cannot say with certainty 

 what is their ordinary food." 



CEcopltm^a unitella (I. B., p. 161), arietellaj Z. This is 

 the solution of Enigma No. 73. I have had several specimens 

 of the larvce this year, some collected by Mr. Scott in this 

 neighbourhood, some by M. Fologne, near Brussels; the 

 perfect insects have always been this species. It is now 

 manifest that the larva which we had previously referred to 

 this insect really belonged elsewhere, and the lai'va of Unitella 

 must have been feeding on the same pea-sticks with it, 

 unknown to Mr. Wing. How easily errors will arise and 

 how difficult to get rid of them when once they obtain 

 currency ! Monsieur Leon Becker has given a notice of the 

 larva of this insect in the 4th volume of the '^ Annales de la 

 Societe Entomologique Beige," p. 106. 



Butalis Incongruella (I. B., p. 167}. Mr. V/ilkinson of 

 Scarborough obtained eggs of this species and has thence 

 reared the larvee. They fed upon heath ( Calluna and Erica). 

 Their motions were very curious and quite different to those 

 of a Coleophora larva, more than half the body being ex- 

 serted from the case, and the case then drawn after them just 

 as we see in the larvae of the Long Horns. Mr. Scott found 

 some larvae of this insect at the beginning of September on 

 a fence at Cannoch Chance (Int. viii. p. 193, — under the 

 headino^ ' Pin-Makin^'). 



Gracilaria Imperialella (I. B., p. 201 ). The capture of a 

 specimen of this insect by the Rev. Mr. Horton has been re- 

 corded in the Intelligencer (vol. ix. p. 43). It was taken 

 near Worcester, May 30th, by sweeping the grass by the side
