OBSERVATIONS ON TINEINA. 25 



The larva of Betuletella is still to be found ; but the idea 

 has occurred to me that, like Assectella, it may feed upon 

 some some species oi Allium, and I believe Allium ursinum 

 grows not uncommonly where Betuletella occurs. 



* Gracilaria fdella, Reutti. Through the kindness of 

 Herr F. Hofmann, of Ratisbon, I received, early in August,' 

 larvEB of this species. They turn down the tips of the leaves 

 of the hop {Humiilus Lupulus) towards the underside, form- 

 ing a sort of conical habitation. 



The larva, as usual in this genus, is devoid of character. 



The perfect insects, which are something like small, neat 

 specimens of Gracilaria heniidacttjlella, appeared between 

 the 21st of September and the 5th of October. 



* Stathmopoda Guerinii, Stainton (Entomologist's An- 

 nual, 1858, p. 152, fig. 5). This singular insect had re- 

 mained perfectly unique till this year. When at Cannes and 

 Mentone, in March, I saw many bushes of Pistacia lentis- 

 cus, some of which had numerous galls on the leaves ; but 

 though Pistacia terebintlius is indigenous in that part of 

 Europe, I am not aware that I ever once met with it. 



In Auo^ust last Dr. Staudinger left Dresden to have two 

 months' collecting at Celles-les-bains, in the Department of 

 Ardeche, in the South of France. From this place he sent 

 me, on the 21st September, some Nepticida larvae, mining 

 in the leaves of Pistacia terehinthus. In writing to thank 

 him for these larvae, on the 28th September, I added as a 

 postscript : *^ I would also call your attention to the fact that 

 No. 2,228 of your Catalogue, Stathmopoda Guerinii, Stain- 

 ton, was ' eclose d'une grande galle du pistachier, le 15 Sep- 

 tembre, 1852.' I only know this one specimen." 



This postscript produced good fruit, for on the 2nd Octo- 

 ber Dr. Staudinger replied : " Many thanks for your letter,
