and difficult to catch." Those who are acquainted with the 

 appearance of a bred specimen of this species must be puzzled 

 to conceive what a wasted specimen can be like ! 



Coleophora ibipennella, Heyden. 

 Alls anticis albis, vents obsolete lutescenti-suffusis, apice fu- 

 scescenti-squamato ; ciliis fuscescentibus ; antennis albis 

 fuscescenti-annulatis, penicillo breviusculo albido. 



Exp. al. 6-7 lin. 



Head, face and palpi white. Antennas white, annulated 

 with pale or dark fuscous, the basal joint with a rather short 

 whitish tuft. Anterior wings white, slightly irrorated with 

 fuscous towards the apex, and sometimes with some faint 

 yellowish veins ; costal cilia tinged with grey, sometimes very 

 decidedly dark fuscous, the remaining cilia generally rather 

 paler. Posterior wings dark grey (darker than in Anati- 

 pennella}, w T ith dark grey cilia. 



This species is closely ailed to Anatipennella and Palli- 

 atella, but is distinguished by its smaller size ; the anterior 

 wings are less irrorated with fjuscous than in Anatipennella , 

 and the yellow veining, of which faint traces may almost 

 always be seen along the subcostal nervure, will separate it 

 readily from both species. 



A most important character is furnished by the position of 

 the case of the larva ; the form of the case is very similar to 

 that of Anatipennella, but it is not so well developed behind, 

 but the mouth of the case is cut off so obliquely that the case 

 does not stand up perpendicularly to the surface to which it 

 is attached, as in Anatipennella, but it lies almost prostrate, 

 the belly of the case resting on the leaf on which the cater- 

 pilU r is feeding. 



I have a specimen taken some years ago at Lewisham, and 

 which I had overlooked as Anatipennella; this year Mr.
