312 Mr. H. T. Stainton's Synopsis 



The perfect insect appears in May and July; it occurs near 

 Bristol, at Stockton-on-Tees, at Renfrew and Fochabers, likewise 

 at Ziirich, Ratisbon, Vienna, and Glogau ; also in Croatia and 

 Finland. 



42. Elaelnsta CtngiUella, Fischer. 



Distinguished from all the allied dark-headed species, by the 

 slenderness and whiteness of the fascia. 



Expansion of the wings 4 lines. Head dark grey ; anterior 

 wings dark grey, with a slender, nearly straight, whitish fascia in 

 the middle ; cilia grey, at the apex whitish. 



Larva unknown. 



The perfect insect appears in June and July ; it« occurs near 

 Vienna, and Mr. Allis has one specimen taken in the North of 

 England. 



43. Elachista Gangabella, Fischer. 



In the dark head and yellowish fascia this resembles Tcenia- 

 tella and Chrysodesmella ; from the latter it may be distinguished 

 by its larger size, duller fascia and blunter apex of the wing; from 

 Tcenialella, which it very closely resembles, it is best recog- 

 nized by the extreme tips of the apical cilia being whitish ; in 

 Tceniatella the cilia are entirely dark. 



Expansion of the wings 4—5 lines. Head dark fuscous ; ante- 

 rior wings dark fuscous, with a nearly straight dull yellow fascia 

 in the middle ; in the $ this is very narrow towards the costa, 

 but in the J it is nearly of uniform width, only a little broader 

 on the inner margin ; cilia fuscous, the extreme tip of the apical 

 cilia whitish. 



The yellowish grey-green larva mines the leaves of Dactyl'ts 

 glomerala and Holcus mollis, making inflated Ltlhocolletiform 

 mines in November and April. 



The perfect insect appears at the end of May and in June; it 

 occurs in several localities near London ; also at Dover and Bris- 

 tol, and on the Continent at Ratisbon ? and Pisa. 



44. Elachista Tcenialella, Zeller. 



Distinguished from the other species with a single fascia, by the 

 cilia being entirely dark, not even the extreme tips being whitish ; 

 only Chrysodesmella agrees with it in that respect. Tcenialella 

 differs from Chrysodesmella in being much larger, and the fascia 

 is darker yellow and duller.
