of the Genus Elachista. 317 



and the other midway between it and the apex of the wing ; cilia 

 white ; posterior wings whitish, with white cilia. 



Larva unknown. 



The perfect insect appears in May and August; it occurs at 

 Vienna and Ratisbon. 



55. Elachista Tnatomea, Haworth. 



Closely allied to the two preceding, but without the scattered 

 dark scales of Dispunctella, and the posterior wings grey instead 

 of whitish ; from Disemiella it may be distinguished by the want of 

 the fuscous tinge along the costa and by its smaller size, and the 

 more obtuse anterior wings. 



Expansion of the wings 4 — 4| lines. Head white ; anterior 

 wings white (though not so pure a white as in the preceding 

 species), with two black spots, one on the middle of the fold and 

 the other midway between it and the apex of the wings ; at the 

 anal angle are a few grey scales ; cilia whitish, with a few greyish 

 scales ; posterior wings grey, with whitish cilia. 



Larva unknown. 



The perfect insect appears in June and July ; it occurs at Sand- 

 erstead and Mickleham, also near Bristol. 



5Q. Elachista Dispilclla, Zeller. 



Differs from the preceding in being smaller and yellower, the 

 anterior wings being nearly of the colour of those of Nitidulella, 

 and there are no grey scales in the cilia. 



Expansion of the wings 3| — 4 lines. Head yellowish white; 

 anterior wings yellowish white, with a faint fuscous spot on the 

 fold beyond the middle, and a darker spot midway between it and 

 the apex of the wing ; cilia pale yellowish white ; posterior wings 

 pale greyish white, with pale yellowish white cilia. 



Larva unknown. 



The perfect insect appears in June ; it occurs nearGlogau. 



57. Elachista Pollinariella, Zeller. 



In the pale tawny fascia and the scattered dark scales this re- 

 sembles the two following species, but from both it is distinguished 

 by the more pointed anterior wings, and the less distinct hinder 

 marginal line in the cilia ; Subocellea, which it most nearly resembles, 

 has the basal fascia much less distinct, and the scattered dark 

 scales are less numerous. 



Expansion of the wings 4 — 5 lines. Head white ; anterior wings
