88 Tromsø Museums Aarshefter 31 ft 32. — 1908-1909. 



Gradation of tarsal joints: Anterior tarsi o* 2, 1 subequal 

 to 3. 4, 5; $ 5, 1 subequal, to 2, 3. 4. Posterior tarsi o* 

 and Ç 5, 2, 1 subequal to 3, 4. The joints of the anterior 

 tarsi with the male subimago are about equal; the 5th 

 joint is a little longer, and the first joint shorter than the 

 others. Pleuræ of segments 7 and 8 squarely truncate, 

 of segment 9 narrowly dilated outwards and produced each 

 into a short acute tooth behind. The first anal nervures 

 terminates close to the anal angle of anterior wings. The 

 angle is slightly projecting. Anal nervures 2 and 3 almost 

 straight. The costal dilation of the hind wing rounded and 

 only slightly projecting. 



The genus is closely related to Chirotoneles and Meta- 

 monius, but differs, besides other characters, by the position 

 of the anal angle of the anterior wing and by having the 

 anal nervures 2 and 3 almost straight. 



I have taken the liberty of naming this genus after Mr. 

 Sparre Schneider who has discovered the species at 

 Karasjok in Finmarken (July 1908), and who has shown 

 the greatest energy in endeavouring to advance the know- 

 ledge of Arctic Norway's insect-fauna.

E. Strand har taget 2 tftf, Subimagines, og 1 Ç i 

 Hatfjelddalen. Sparre Schneider har taget Arten i 1908 

 ved Lakselv i Juni, ved Karasjok og Jalve i Juli og paa 

 Nordmo i August.

I „Ehpemeridæ collected by Herr E. Strand in South 

 and Arctic Norway" nævner Eaton, at 13 Eksemplarer er 

 fundne ved Aal og 1 Ç , Subimago, er taget i Hatfjelddalen; 

 han sætter dog Spørgsmaalstegn ved sidstnævnte Lokalitet.
