[Read 7lh August, 1854,] 



Genus Sisyra, Burm. 

 terminalis, Curt. 



Slightly pubescent ; head and thorax shining, deep ochreous. 

 Abdomen brown. Antennae much longer than the body, capillary 

 but slightly tapering, pilose and moniliform; black, about twelve 

 of the terminal joints ochreous white, excepting the apical one, 

 which is black. Wings slightly iridescent, superior tinted with 

 smoky ochre, inferior colourless ; nervures pilose, pale ochreous 

 brown. Legs whitish ochre. 



Expanse of wings 6 lines. 



This very distinct species is at once distinguished from all the 

 other Hemerohii by the pale terminal portion of the antennae, com- 

 prising about one-quarter of the whole length. It associates with 

 H.fuscntus, Fab., and H. nigripennis, Wesm. ; which are charac- 

 terised principally by the absence of transverse nervures in the 

 wings, and have been constituted as the genus Sisyra by Bur- 

 meister. H. terminalis I discovered at the base of Turk Moun- 

 tain, near the Lakes of Killarney, in a tour of the west of L-eland 

 made in 1835 with my friend Mr. Haliday. The specimens were 

 beaten out of an oak tree the 9th of July. 



Genus Hemerobius, Linn. 

 dipterus, Burm. 



Hispid, brown. Antennae longer than the body, capillary, mo- 

 niliform, pitchy and but slightly pubescent. Wings; superior 

 rather small, elliptic, slightly tinged with ochre, nervures hispid 

 and brown round the margins, the transverse ones forming irre- 

 gular brown spots ; inferior wings resembling two small oval lobes. 

 Legs pale ochreous, knees pitciiy. 



Expanse 3| lines. 



This species, which is unique as British, was taken by J. C. Dale, 

 Esq., off' a hazel bush, outside of Breach-wood, Aller-hill, near 

 Langport, Somerset, the 26th June, 1843.
