The colour of the ahclomen and legs varies, even in 

 the same brood ; but the species is easily known by its 

 structure. The antennae are testaceous at the extreme 

 base ; those of the <? are also frequently dull rufous 

 beneath. 



An abundant parasite, living in small families, or 

 solitary, according to the size of the larva attacked. 

 Not common in Geometry, but once bred by Bignell (four 

 males, five females) from Gnophos ohscnraria, Hiib. 

 Usually infesting singly the leaf-mining Tiime. Beared 

 twice by Ehsha from Lithocolletis lantanella, Schr,, 

 March 14th ; from Gracilaria tringiijennella, Zell., May 

 31st ; semifascia, Haw., July 17th ; Psijchoides Verhuel- 

 lelliis, Hej'd., Catoptria cemulana, Schl., Sept. 4th ; and 

 Nannodia Hermannella, Fab., June 9th. By Parfitt and 

 Fletcher from Lithocolletis vaccinieUa, Scott. By W. H. B. 

 Fletcher from Ehichista tcBuiatdla, Staint., May 9th. On 

 the Continent, by Eeissig and Eatzeburg, from L. cavella, 

 ZelL, pomifolielia, Zell., emherizipennella, Bouche, Tis- 

 cheria complanella, Hiib., &c. By Brischke from Plutella 

 porrectdla, L., Lithocolletis lantanella, Schr., and L. spini- 

 colella, Kol. Eatzeburg remarks that the parasitic mag- 

 got works its way through the dry epidermis of the leaf 

 inhabited by the Tinea, and attaches its cocoon by a few 

 threads to the under side. Bouche's " ardeaepenella" 

 was from Gracilaria syringella, Fab., = ardeipennella, Tr. 

 Captured frequently in England, by Dorville, Bignell, 

 Bridgman, Haliday, &c. Cocoons white, according to 

 Bouche; greyish brown, according to Eatzeburg; pale 

 yellow, according to Parfitt ; silky-white and single, 

 according to Brischke. Those which I received from 

 Bignell were of the usual silvery white.
