5. Æschna mixta Latr. One specimen, $ . As far as I 



know, it is the first record of that species from Corsica. 



6. Calopteryx virgo Lin. This species was well represented 



in the collection. 



7. Calopteryx hæmorhoidalis v. d. L. There were pre- 



sent long rows of this beautiful species. The female is 

 a very fine looking insect, especially when the dark co- 

 lour at the tip of fore wing is present. 



8. Sympycna fusca v. d. L. Several females and one male. 



9. Pyrrhosoma tenellum Vill. Two specimens, males, were 



present. 



10. Ischnura genei Pict. Of this very interesting species 

 seven males and one female were found in the collections. 



11. Agrion cærulescens Fonsc. One specimen, male, was 

 found. 



Ephemerida. 

 The Ephemerid fauna of Corsica seems to be a rich one, 

 and it is very interesting that nearly all the species described 

 by Hagen are re-found. Rev. A. E. E a - 

 ton has looked upon specimens of Ha- 

 brophlebia modesta and H. nervulosa, and 

 he communicates that they agree with the 

 descriptions, but he has not had the op- 

 portunity of comparing them with the 

 type-specimens, which are placed in the 

 collection of the late R. MacLachlan. 

 1. Habrophlebia budtzi Peters. 



(Thraulus Budtzi Petersen, Ent. Med. 



København, 1912, pag. 349). This 



species was described from a single 



specimen, male, the genitaliæ of 



which were shrivelled. As I have got 



four specimens more, I can see, that 



the species must be placed in Habro- 

 phlebia, and next to Habrophlebia Habrophlebia budtzi. 



lauta Mac Lachl., to which species Forceps and penis, 



seen from above. 



Fig. 1. 



it has much likeness, but from 



a penis, seen from side.
