300 Mr. H. T. StaiiUon's Synopsis 



1 1 . El.ich/sta Liitlcomella, Zeller. 



By tlie yellow head this is readily distinguished from all the 

 allied species except Flavicomella, but Flavicomella has a small 

 brown spot on the crown of the head, and is a smaller, duller 

 insect than Lulicomella. 



Expansion of the wings 4| — 5| lines. Head and palpi bright 

 yellow; anterior wings dark brown; a rather curved yellowish- 

 white fascia before the middle, and two opposite spots of the same 

 colour beyond the middle, that on the costa slightly posterior. 



The pale yellow larva mines down the leaves and stems of 

 Dactyiis glomerata, making linear, whitish tracks in April. 



The perfect insect appears in June ; it occurs generally in 

 England and Scotland, also at Glogau and Ziirich. 



12. Elachista Flavicomella, Stainton. 



Distinguished by its yellow head, with a small brown spot on 

 the crown ; it is a smaller, duller insect than Luticoinelld , and 

 the opposite spots are more nearly opposite. 



Male. — Expansion of the wings 3g lines. Head and palpi 

 yellow, a brown spot on the crown of the head ; anterior wings 

 greyish-brown, with a slender yellowish-white fascia, slightly 

 oblique, before the middle, and two small yellowish-white op- 

 posite spots beyond the middle, that on the costa hardly pos- 

 terior. 



Female. — Expansion of the wings 4 lines. Head and palpi as 

 in the male ; anterior wings greyish-brown, with a broad yellowish 

 fascia beyond the middle, and with the opposite spots prolonged 

 into the cilia, making nearly the whole of the apical portion 

 yellowish. 



Whether this is the normal appearance of the female, or only 

 a variety, I cannot say, having only seen one specimen. 



Larva unknown. 



The perfect insect appears in July ; two specimens were taken 

 by Mr. Shield on the 15th of that month at Howth in Ireland. 



13. Elachista Atricomella, Stainton. 



This is closely allied to Kilmunella and Pace; in the latter the 

 fascia and spots are much less distinct. From Kilmunella it is 

 best distinguished by the anterior wings being blacker, and more 

 pointed, and the fascia is more slender, and nearer the base on the 

 costa.
