222 [March, 



Expansion of the wings, 9 — 11 lines ; head pale greyish-ochreous ; 

 face palei' ; palpi with the second joint ochreous beneath, externally 

 greyish-fuscous, the terminal joint entirely pale yellowish ; antennae dark 

 fuscous. Anterior wings pale greyish-ochreous, with a faint violet gloss 

 near the base towards the inner margin, sparingly clouded with 

 pale grey ; at the base of the costa is a minute dark spot, (not 

 nearly so large as the black spot we see in adspersella), and on the hind 

 margin is a row of dark spots ; near the base is a short oblique dark 

 streak from the inner margin ; the position of the conspicuous black 

 spots is as follows : — one high up on the disc before the middle, 

 one on the fold obliquely beyond, and one on the disc a little beyond 

 the middle, these three spots almost forming an equilateral triangle ; a 

 little beyond the third spot, and lower down, is a smaller and less dis- 

 tinct spot, (almost in a line with 3 and 1) ; cilia whitish-ochreous ; 

 posterior wings pale grey, with whitish-grey cilia. 



The larva I have thus described : — Length, 9 lines. Green : head 

 black ; second segment brown, shading to black-brown posteriorly and 

 at the sides ; front of the incision between the third and fourth seg- 

 ments reddish-brown ; ordinary spots small and black. "When full fed 

 there is a faint appearance of darker bands across the middle of each 

 segment, most conspicuous at the sides, where, when the larva is near 

 pupation, they almost form blotches. 



Feeds on Siler aquilegifolium in June, near Vienna. 



DESCRIPTION OF a GENUS & SPECIES ok BBACHELTTRA NEW TO BRITAIN. 

 BY DE. J. A. POWER. 



I have the pleasure of adding the following most interesting genus 

 and species of Brachelytra to our Fauna. 

 BoEBOROPORA, Kraatz, Berl. Ent. Zeit., vi., 404 (1862). 

 Saulcyi, Kraatz (loc. cit.). 



JBorhoropora has a close external resemblance to Scopteiis, but its 

 structural affinities are with the Aleocharidce. The pedunculated head, 

 and four jointed anterior tarsi, bring it near Falagria ; to which 

 Dr. Aube's original specimen was at first referred by Kraatz himself. 



From any known genus of the group it may be distinguished by 

 the very large sub-quadrate head, and thepecialiar formation of the oral 

 organs ; the mandibles being very slender and produced, and the right 

 one having a large strong tooth at the base. The labial palpi are sub- 

 acuminate at the opex.
