308 Mr, H. T. Stainton's Synopsis 



31. Elachista Pullella, Fischer. 



This comes very close to Suhnigrella, but in the male the 

 fascia and spots are more distinct; in the females of the two 

 species I find no perceptible difference. 



Male. — Expansion of the wings 4 lines. Flead grey; anterior 

 wings rather dark grey, with a rather indistinct, slightly angulated 

 fascia before the middle, and two whitish opposite spots beyond 

 the middle (of which that on the costa is slightly posterior), and 

 sometimes with a few intervening whitish scales, which appear to 

 connect the spots and to form with them an angulated fascia ; 

 cilia grey, 



Larva imknown. 



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

 several continental localities. It may be only a modified form 

 of Suhnigrella ; a point which the discovery of the larva must 

 determine. 



32. Elachista Perptexella, Stainton. 



Differs from Pullella and Suhnigrella by the blacker anterior 

 wings, and the spots more nearly opposite; closely allied to 

 Airce, but a trifle smaller, and the apex of the wing more ob- 

 tuse ; the larva, like that of Airce, mines the leaves of Aira 

 ccespitosa. 



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

 greyish-black, with an indistinct oblique pale fascia before the 

 middle, and two whitish spots, almost exactly opposite, beyond 

 the middle ; the apex of the wing is rather obtuse ; cilia grey. 



The female is only a little darker in colour, with the markings 

 more distinct. 



The larva, which is whitish-yellow, mines the leaves of Aira 

 ccespitosa in April and June. 



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

 London and at Scarborough, also near Zurich. 



S3. Elachista Airce, Frey. 



Closely allied to the preceding, but larger, and the anterior 

 wings more pointed ; from Pace it may be best distinguished by 

 the opposite spots being more distinct. 



Expansion of the wings 4| — 5 lines. Head dark grey; an- 

 terior wings dark grey, with a rather indistinct, slightly oblique, 

 whitish fascia before the middle ; beyond the middle are two
