abdomen. In size it is smaller than the male, expanding 

 only 9'". 



Setodes reducta, M^Lachlan. Mystacides ferruginea oi 

 Ed. Pictet (Nevropteres d'Espagne, p. 95, pi. xiii, fig. I 

 — 6) is probably identical with this insect. 



Family HYDROPSYCHID^. 



Sydropsyche fulvipes, Curtis. I have received from 

 Mr. Dale both sexes of this insect taken at the same locality 

 as were Curtis's types. I am now convinced of its distinct- 

 ness from H. angustipennisj with which I had previously 

 united it. 



Hydropsyche ophthalmicay Rambur. I expressed a 

 doubt (Trichop. Brit. p. 130) whether the female of this 

 species possessed the large eyes which so abundantly distin- 

 guish the male. I can now safely aver that the female has 

 the ordinary small eyes, having found an example of that sex 

 with the males at the usual Thames locality. Excepting in the 

 eyes it differs from the male only in its slightly increased 

 size. I now think the Parisian example of this sex, pre- 

 viously referred to, does not belong here. 



Wormaldia sulmigra, M*Lachlan, occurred somewhat 

 commonly at a little waterfall, at Scalby Beck, near 

 Scarborough. Mr. B. Cooke has it from Rannoch and 

 Ireland. 



Cyrnus flavidus^ M*Lachlan. This insect is in Mr. B, 

 Cooke's collection, from Rannoch, and also from near Man- 

 chester. Hence the hopes I previously expressed have been 

 reahzed. In a letter, received from Vienna, it has been re- 

 ported from Podolia, a province of south-eastern Russia. 



Family RHYACOPHILID^. 

 Genus Ber^a. The characters of this, both generic and
