Nemoura. — This genus has been divided by Kempny and Ris into 

 several sub-genera, and the species are as follows : — 

 Sub-genus Protonemurn, Kempny. 

 prcecox, Morton. 

 meyeri, Pict. 

 Sub-genus Amphinemura, Ris. 



cinerea (OH v., Pict.), Morton. 

 *sfandfussi, Eis. Distinguished from cinerea especially 

 by a remarkable arrangement of dark spines on 

 the appendages. Taken by me in Scotland many 

 years ago, but I have not seen it recently. 

 Sub-genus Nemura, sens. str. 



varlegafa, Oliv. et Auct. 

 *mnrqinata (Pict.), Kiap. = lateralis, Mort., Trans. 

 Ent. Soc. Loud., ISOi, p. 5G4. I now agree that 

 Klapalek's view is likely to be the more correct, 

 and I have adopted it, as has also Dr. Ris in 

 his valuable paper (Die Schweizerischen Arten 

 der Perliden-Gattung Nemura. Mitt. Schweiz. 

 Entom. Gess., Bd. 10, Heft 9). Occurs in Devon 

 and Scotland, and probably elsewhere. 



cambrica (Steph.), Mort. 

 avicnlaris, Mort. 

 Sub-genus Nemurella, Kempny. 



inconspicua (Pict.), Mort. This name has been adopted 

 by Ris, but not by Klapalek, who has called the 

 species picfefii. 



Leuctra. — I have already given notes on the British species. See 

 vol. xxxviii, pp. 255-6. They are : — 

 geniculata, Steph. 

 klapdleki, Kempny. 



fusciventris, Steph. ? 

 alhida, Kempny. 

 liippopus, Kempny. 

 handlirschi, Kempny. 



race or var. inermis, Kempny. 

 niffra (Oliv.), Klap. 



13, Blackford Road, Edinburgli : 

 December lOth, 1906. 



* Now formally recorded as British, I think, for the first time.
