134 Mr, H. T. Stainton's Remarks on Extracts 



lowish ; whereas, in argyropeza, Zeller says, " Cilia clear-grey, 

 scarcely tinted, a little yellowish." 4tli. Our insect swarms on oaks 

 in June ; his frequents aspens in May. The second and third 

 of these differences are commented on by Zeller in a note ; but he 

 says, *' the third and weightiest arises from the want of certainty 

 that this suhbimaculella is a Nepticula, since the genus Microsetia 

 contains smooth-headed and rough-headed species, — species with 

 and species without the enlarged basal joint of the antennee ; and 

 in no species does Stephens inform us of the nature of the parts 

 of the head."

" Alis anterioribus violaceo-fuscis, macula dorsi medii argentea, 

 ciliis externe canis ; capillis ferrugineis ; antennis cum con- 

 chula exalbidis." 



" A single female, the size of a small argyropeza, and very 

 similar to the female of that species. Ground-colour of the ante- 

 rior wings dark violet brown, the cilia at the apex encompassed 

 with a dark ring of scales. The specific distinctions appear to be 

 the following : the costal spot is wanting on the anterior wings, 

 as also the other spot ; only, the inner marginal spot is here, 

 nearly triangular, placed on the margin in its usual situation, but 

 shinbig silvery white, &c." 



" I took this single specimen near Glogau ; but 1 know nothing 

 further about it."* 



" Sp. 9. Hemargyrella, Koll." Linn. Ent. vol. 3, 323. 



" Alis anterioribus exalbidis nitidulis, apice fiisco-violaceo ; 

 capillis pallidis ; antennis fuscescentibus, conchula exalbida." 



" Smaller than argyropeza, easily known from it, since the an- 

 terior wings are yellowish white from the base to rather beyond 

 the middle. 



" I took this scarce species in May twice on the trunks of 

 aspens on the fortifications of this place ; I saw a single specimen 

 from the neighbourhood of Laubau, and two others from the 

 Riesengebirge. Besides it occurs near Vienna in beech woods. 

 Closely allied apparently to Jloslactella of Haworth, but in that 

 species is a distinct black fascia across the yellowish portion of 



* Mr. Sircom met with this species among sallows, near Brislington, about 

 the middle of June, this year.
