ADDITIONAL NOTES ON THE NEUROPTEEA OF THE ISLAND 



OF SARK. 



BY ROBERT McLACHLAN, F.R.S., &c. 



Since my notes at p. 6 ante were published, Mr. F. Y. Theobald, 

 B.A., F.E.S., has sent me a few species collected by him in Sark in 

 1890. I find among them the following species not hitherto recorded 

 from that particular island, including several that have not been noticed 

 in the Channel Islands generally, and which are otherwise interesting. 



TRICHOPTERA. 



Limnophilus vittatus, F. 



Halesus digitatus, Schrk. — 1 ^ . 



Philopotamus insularis, McLach. — 2 examples. It is thus made evident that 

 this form is not confined to Guernsey, and indeed, Mr. Luff informs me that he now 

 remembers having taken the insect some years ago at a very small swift stream at 

 Point du Moulin in the west of the island. Sark is only six miles from Guernsey by 

 sea, but there is often considerable difference in the insect productions of the two 

 islands. As examples, Argynnis Aglaia and Coenonympha PampJiilus may be cited, 

 both being common in Sark and apparently absent from Guernsey. 



Ehyacophila dorsalis, Curt. — Two S of this insect, which is so universally 

 distributed on the British mainland and in Ireland. P. munda, McLach.— One ^. 

 A most interesting discovery. In England it seems to occur only in the Dartmoor 

 and Exmoor districts, and its known distribution on the Continent is confined to the 

 Departement de I'lndre, where it has been found commonly by M. Rene Martin, of 

 Le Blanc. 



PSEUDO-NEUROPTERA. 



Ephemera lineata, Eaton. — One ? . A decidedly local species. 

 Mschna mixta, Latr.— One $ , taken by Mr. Luff. 



Lewisham, London : January, 1892.
