IN SEARCH OF ENTOMOLOGISTS. 123 



very existence I had previously had no definite notion, 

 though aware that Herrich-Schaffer had a Gelechia Kr'ds- 

 manniella, p. 166, No. 412, Fig. 581, which is, I believe, 

 identical with our Gelechia Hilbneri. Herr Krosmann's 

 collection was not particularly rich in Micros; they were 

 evidently not h\s forte, but I found there several species with 

 which I was not previously acquainted, and picked up much 

 valuable information. Herr Krosmann is very successful 

 in breeding the rotten-wood and fungus feeders, and rears 

 freely that lovely insect Tinea nigralbella from fungi on 

 alder-trees, also Tinea arcella from rotten-wood ; from the 

 same pabulum he also rears, though not commonly, Anchinia 

 Balucella, F. v. R. (H.-S. vol. v. p. 143, fig. 617) ; of this 

 he gave me a specimen, which only differs in size from (that 

 great rarity with us) Aplota palpella, and Herr Krosmann 

 assured me that he had seen it more than once only half the 

 size of the large specimen he gave me (see ante, p. 53). 

 He also gave me bred specimens of Incurvaria Korneriella, 

 and Adela viridella, with the cases from which the respec- 

 tive individuals had emerged ; these cases had been found 

 amongst fallen leaves in the spring. Korneriella will cer- 

 tainly be found in some of our beech-woods ; he had also 

 bred two or three of (Ecophora fianifrontella from cases 

 found on the ground. 



He gave me specimens of Laverna conturbatella and Bu- 

 talis inspersella, both bred from the shoots of Epilobium 

 angust folium (what a hint for those Entomologists who 

 live where that plant grows freely!), and Chauliodus Illige- 

 rellus, bred from larvae feeding, at the end of May and be- 

 ginning of June, on JEgopodium podagraria (indeed that 

 very evening Herr Krosmann went out and got some of 

 these larvae, and I found them waiting for me at the Hotel, 

 on my return late at night from the Opera Guillaume Tell !) 

 A singular circumstance was that Herr Krosmann showed
