270 Mr. H. T. Stainton on the 



very peculiar, owing to the costa being slightly indented beyond 

 the middle. 



In the neuration of the posterior wings the forked apical vein 

 is branched all the way from the cell, whereas in every Elachista 

 that I have examined this vein is not forked till long after it 

 leaves the cell, nor indeed till it is very near the apex. 



This genus only contains a single species, Brunnichclla, for 

 much as Elachista Alagnijicdla resembles Bninnichella in mark- 

 ings, the longer palpi and unindenied costa of the anterior wings 

 o^ Magnificella are reasons with me for referring it still to the 

 genus Elachista. 



1. Stephensia Brunnichella, Linneus. 



This insect has a considerable likeness to Elachista Gleichen- 

 ella and E. Magnijicella. From the former it is best distinguished 

 by the position of the apical spots ; in Brunnichella the spot at 

 the anal angle is placed perpendicularly, the costal spot is con- 

 siderably beyond it and points backwards to the dorsal spot, 

 whereas in Gleichenella the spots are almost opposite, and are 

 united by an intermediate third spot placed a little posteriorly, 

 with which they form an angulated fascia ; in Magnijicella the 

 spots, it is true, are not united, the costal spot is posterior to the 

 dorsal spot, but it is almost perpendicular, and does not slope 

 backwards ; besides, in Magnijicella the central fascia stops short 

 before it reaches the costa. 



Expansion of the wings 3 — S\ lines. Head, face and palpi 

 golden brown ; antennae dark fuscous, with a broad white ring 

 before the apex. Anterior wings dark golden brown, with a 

 golden fascia close to the base, a slender bright golden fascia in 

 the middle, and two brilliant golden spots towards the hind 

 margin, one perpendicidarly placed at the anal angle, the other be- 

 yond it and pointing inwards on the costa ; cilia purplish-grey ; 

 posterior wings greyish -brown, with grey cilia. 



The larva, which mines the leaves of Clinopodium vulgare in 

 April and July, forming large, brown, slightly puckered blotches, 

 is greenish-white, with dark green dorsal vessel; the head is 

 dark brown, almost black, and the second segment bears on the 

 back a plate of the same colour, divided in the middle by a 

 central pale line. The six anterior legs, eight ventral and two 

 anal prolegs, are of the colour of the body. 



The perfect insect appears in May and August.
