58 Eev. T. A. Marshall's monograph of 



a Tinea which Eatzeburg calls Lithocolletis cavella, Zell., 

 but as this feeds on birch the species intended may be 

 L. tristrigella, Haw. Obtained by Nicelli from L. querci- 

 foliella, Fisch. In England by Dorville, Barrett, and 

 Elisha, from L. lautella, Zell. ; by Elisha, March 14th, 

 from L. tendla, Zell. ; and by Fletcher, May 9th, from 

 Tischeria dodoiKsa, Heyd. Prematurely forced at the 

 end of February by Elisha from Lithocolletis Bremiella, 

 Zell., lautella, Zell., cavella, Zell., and Nepticida aucu- 

 parice, Frey ; March 20th from L. Cramerella, Fab. ; 

 and April 27th from L. lantanella, Schr. At Cam- 

 bridge bred by Warren from Ornix hetulce, Staint. 

 It does not confine its attacks to Lepidoptera, having 

 been reared by Reissig and Nordlinger from Orchestes 

 fagi, L., and from dipterous leaf-miners, as Phytomyza 

 nigricornis, Macq. Brischke reports it from a Phyto- 

 myza, and also from Cryptocampus bellus, Zadd. Inch- 

 bald and Fitch have bred it from a fly mining the 

 leaves of Symphoricarpus ; and the latter on July 17th 

 from Phytomyza lonicerce, Desv., in the leaves of honey- 

 suckle. The diversity of food may account for the 

 differences of size and colour in these parasites.
