24 OBSERVATIONS ON TINEINA. 



tions of the larva of this species on the leaves of Smilax 

 aspera, some being mined by the youno: larva, others gnawed 

 externally by the adult larva; but I was not successful on 

 that occasion in meeting with any of the larvae. About a 

 week later I first met with the larvae at Mentone, in a shady 

 place ; and on the 21st of March I met with them in some 

 plenty, and have bred from them a nice series of the imago. 



The larva I have thus described : — 



Length 2J lines. Dull greenish-grey, with the dorsal 

 vessel darker, the sides paler; head pale yellowish-brown; 

 the second segment of the same colour, with two ti-ansverse 

 rows of small black spots; the transverse spots on the third 

 and fourth segments are distinctly perceptible; the spots on 

 the other segments imperceptible. Not unfrequently, espe- 

 ciall}^ when nearly full fed, it appears with deep red sub- 

 dorsal lines, and is then a very handsome larva. 



When young it makes small, clean mines in the leaves, 

 the excrement being ejected through a hole in the under- 

 side of the leaf. Afterwards it gnaws the leaves half- through 

 from the underside in narrow strips, often covering itself 

 with a thin layer of '* frass" and silk. 



The open network cocoons are made of brown silk, through 

 which the pupa is distinctly perceptible. 



The moths appeared with me from the 16th to the 2(5th 

 of April. 



Acrolepia hetuletella. Mr. Sang has again had the plea- 

 sure of capturing this insect at Castle Eden Dene, at the end 

 of September, and most liberally added the species to my 

 collection. 



Herrich-Schiiffer and Wocke both labour under the de- 

 lusion that the Betuletella of Curtis is the Continental onion 

 and leek-feeder Assectella; but the two species are abun- 

 dantly distinct.
