nothing M^batever. At first I thoiiglit this was due to several sus- 

 picious-looking mills along its course ; but these, on closer acquaintance, 

 seemed to be of a harmless nature (so far as poisoning the water is 

 concerned), and I M^as forced to the conclusion that the absence of life, 

 both animal and vegetable, in this stream is caused by irrigation, which 

 for a part of the year diverts the water and leaves the natural course 

 dry. Of standing water there is very little ; what there is mainly 

 consists of the filtration from the sides of disused granite quarries, 

 with a few small artificial ponds in private grounds. But in the west 

 of Jersey there is a very considerable sheet of water, known as St. 

 Ouen's Pond, to which I was able to devote only one hour. 



The foregoing notes are essentially apologetic for the paucity of 

 my captures. Mr. Luff's list will hereafter prove that a resident in 

 one of the islands, working all through the year, and with an intimate 

 knowledge of the country, can show better results ; but at its best 

 the list wall not be long. 



I was unfortunately not able to visit Alderney, owing to the brief 

 stay I was able to make in the islands. Its closer proximity to the 

 French coast renders an examination of its productions much to be 

 desired, more especially regarding the problem opened up by the genus 

 Philopotamus, and from the same cause a knowledge of what is to be 

 found along the whole of the French coast opposite to the islands is 

 also highly desirable. 



Sark is a little gem of an island. It is not over-cultivated, and, 

 for its size, it possesses a very respectable stream running through a 

 wooded valley (Dixcart Valley), in which are some noble ash trees, &c. 



aUERNSEY. 



Teichopteea. 



Liplectronafelix, McL. — Saints' Bay and Le Grouffre. Of course it is a mere 

 coincidence, but here, as everywhere that I have taken the species, it is associated 

 ■with brambles most trying to the entomologist. 



Philopotamus insularis, McL. — This form (for it is difficult to consider it a 

 species) came originally from Saints' Bay, but it occurs also at Petit Bot and Le 

 Grouffre, and perhaps in other small valleys in the south of the island. Those from 

 Le Gouffre seem to be decidedly smaller and more strongly spotted than the others, 

 and it is the most westerly locality. This is of some importance, as bearing upon 

 the forms of Fhilopotamus found in these islands. 



Plectrocnemia geniculata, McL., and P. conspersa, Curt., occurred at Saints' 

 Bay and Le G-ouffi'e. 



Rhyacophila septentrionis, McL. — Saints' Bay ; common at Le Gouffre. 

 Planipennia. 



Chrysopa flavifrons, Brauer. 



Hemerohius or at y pus, Wallengr. 



Pseudo-Neueoptera. 



Psocus bifasciatus, Latr. 



Ccecilius pedicularius, L., and flavidus, Steph.
