146 [June, 



arrived compares most favourably with almost anything I have seen 

 in the wav of Neuroptera sent from abroad, and speaks of most care- 

 ful collecting and handling, I would like to express here my thanks 

 to Miss Fountaine for the courteous and ready way in which she has 

 assisted me in this matter. 



The collection proves to be of much interest, as it adds, as far as 

 I can ascertain, two or three species to the Algerian fauna, and es- 

 pecially it comprises a fine series of the genus Ischnura^ including a 

 species that is certainly new. I propose to describe this new species 

 now, and at the same time to give an annotated list of the other 

 species of Odonata taken— 22 in all. 



In connection with the following notes it will be found useful to 

 refer to the paper by the late Mr, McLachlan, " Odonata collected by 

 the Eev. A. E. Eaton in Algeria," &c. (Ent. Mo. Mag., xxxiii, July, 

 1897, pp. 152 — 157). There is a considerable difference in the com- 

 position of the two collections. In point of numbers Miss Fountaine's 

 captures compare well with those of Mr. Eaton — considering that 

 they represent the result of but one season's collecting by one who 

 had no previous knowledge of the Order. There is, however, an 

 absence of some important forms of Mediterranean or North African 

 type. This may be due in part to the fact that Mr. Eaton's came 

 largely from the eastern province of Constantine, while much of 

 Miss Fountaine's collecting was done in the province of Oran, which 

 Mr. Eaton did not visit. 



Subfam. Libellulinje. 



St/mpetrum fonscolombn, Selys. — The (? of this species when fully udult is in 

 life a beautiful insect, and it much attracted Miss Fountaine, who sent a fine series 

 of it from Sebdou, taken from June 26th till August 8th. It also occurred at 

 Tlemcen, July 12th. 



S^mpefrum striolatum, Charp. — T^niet-el-Haad, June 15th and 18th ; Sebdou, 

 July 1st ; evidently less commonly met with than the next species. 



Sympetnnn meridionale, Selys. — Teniet-el-Haad, June 14th and 18th ; Sebdou, 

 from June 27th till August 9th ; also Tlemcen, July 13th. 



Crocothemis erythrxa, BruUe. — Biskra, April 2nd and 3rd. McLachlan {I. c.) 

 remarks on the great variation in size and in intensity of colour. The latter no 

 doubt depends on age. These Biskra examples are rather small. 



Orthetrvm ramhurii, Selys. — Biskra, April 2nd, and Hammam E'Irha, April 

 11th, about half a dozen specimens, all teneral but one. I think, however, they 

 are certainly all ramburii. 



Orthetrnm nitidinerve, Selys. — Teniet-el-Haad, June 8th, 10th, and 17th ; 

 Sebdou, June 23rd to 3()th, and odd specimens on till July 23rd.
