oO LEPIDOPTERA. 



Pancalia Latreillella and Leuwenhoekella. — Here 

 we have a very distinct genus, of which the larvae are en- 

 tirely unknown ; the habits of copulated individuals, and, if 

 possible, of ovipositing females, should be observed. 



AcROLEPiA perlepidella and betuletella. — From 

 v/hat we know of the larvEe of the genus Acrolepia, these 

 ought not to be difficult to find. 



Roslerstammia pronubella. — We have no clue to the 

 habits of this very rare insect. 



Glyphifteryx fuscoviridella. — This insect, so com- 

 mon with us in flowery meadows at the end of May, is un- 

 known in Germany; the larva ought to be findable. 



G. Thrasonella. — From the habit of the imago this 

 larva must feed on or in rushes. 



Zelleria hepariella, insignipennella and fascia- 

 pennella. — Though I bred Hepariella more than twenty 

 years ago from a white cocoon on an ash leaf, we are still 

 ignorant how to find the larva. Fasciapennella has hardly 

 been taken for the last 20 years I believe ; it is an autumnal 

 insect. 



CoRisciUM SULPHURELLUM. — There is something mys- 

 terious in the larva of this species still escaping the obser- 

 vation of all the Micro-Lepidopterists of Europe. 



Batrachedra PiNicOLELLA. — The imago is often plentiful 

 amongst fir trees, but where and when does the larva feed ? 

 Chauliodus insecurellus. — I fear the locality where 

 this used to occur near Stoat's Nest, beyond Croydon, in 

 1846 and 1847, is now all brought into cultivation. The 

 larva should be sought, at the end of June or beginning of 

 July, on UmbeUiferce growing on the chalk-do^\Tis. 



Chrysoclista bimaculella. — The larva probably feeds 

 beneath the bark of some tree, perhaps of sallow. 



LiTHOCOLLETis ULicicoLELLA. — No w that -5co/?ane//rt has
