I have not yet been able to differentiate the larva from that of 

 aureUa or other allied bramble species. The only other species of 

 Nepticula that to my knowledge occurs in bramble in the neighbour- 

 hood of Weymouth is the common aurella, which is found everywhere, 

 sometimes abundantly. 



The following is a description of the new species, which I propose 

 to call auromarginella, on account of the striking character which 

 distinguishes it from all others of its genus : — 



Exp. al., 2\ — 2i lines. Fore-wing greenish-bronze, becoming darker and more 

 violet on the basal side, of a somewhat broad, nearly straight, pale golden fascia, 

 which crosses the wing a little beyond the middle ; on the extreme hind margin is a 

 similar narrower, crescent-shaped, pale golden fascia ; the space between the fascise 

 is dark violet, the whole of the wing being beautifully metallic. Hind-wings and 

 fringes grey, with a bronzy glass. Head ferruginous ; eye-caps cream coloured or 

 pale ochreous ; thorax like the basal half of fore-wing ; antennce, body and legs 

 darker, the legs with light rings. 



This species cannot be confounded with any other, on account of 

 its golden hind margin ; it resembles aurella in some respects, but is 

 smaller, and the basal portion is not brown as in that species, but 

 rather bronze-green.

DESCEIPTION OF THE MICROPTERYX OF THE HAZEL 

 (J/. KALTENBACHII). 



BY H. T. 8TAINT0N, F.E.S. 



Exp. al., 4 — 5 lines. Head dark brown, inclining to grey (greyer in the female). 

 Antennse short, black, about half as long as the anterior wings, thus not so short as 

 those oi purpurella. 



Anterior-wings greenish-bronze, sparingly irrorated with red, with a small tri- 

 angular pale spot (not sharply defined) at the anal angle ; other specimens are more 

 considerably irrorated with red, but the red markings are never so neat as in purpu- 

 rella, salopiella, and Sparmannella ; sometimes the pale ground colour is almost 

 entirely suffused with red, which then appears to be the ground colour, the pale spot 

 at the anal angle being then the only vestige of a marking. 



The form first described above is that which best agrees with the 

 original sj^ecimens bred by Herr Kaltenbach, and which he had re- 

 ferred to fastuostlla. In 1862 I visited Aix-la-Chapelle, and called on 

 Herr Kaltenbach, September 17th, never dreaming then that the insect 

 he had bred was a Micropteryx till then totally unknown to us ; I 

 then thought it must of course be referred to some one or other of 

 the species we knew, and I agreed with Herr Kaltenbach as to their
