Cubitus and cliscoklal nervure present, but less marked than the other nervures 

 Anterior legs testaceous or reddish-yellow, except basal half of coxae, which are 

 black ; hinder legs darker, femora with traces of darker lines, especially at base and 

 apex ; coxsB as those of front legs. Wings not quite hyaline ; nervures much the 

 colour of the front legs, and st igma of the hind ones. Very close to A. hyali-nipennis, 

 Kieff., and to A. fvuscipennis, Kieff., but apparently distinct. 



This species is described from a single specimen taken by Mr. W. 

 Evans at Luffness Links, Scotland, on July 19th, 1898. [It may 

 well be that Mr. Chitty intended the name of this species to be 

 " luffnasensis " ; I have only MS. to take it from, and am strongly of 

 opinion that he altered his mind as regards the more correct rendering 

 of the Latinised locality ; if the above be the less classic form, the 

 fault is my own. — C. M.] 



A.TSTMOTS OBSCUEICORNIS, Kieff., <$ . 



Only the ? of this species is described. For the $ follow Kieffer's table to 

 No. 25. Head shining, sparingly punctured. Parapsidal furrows indicated. 

 First part of radius three times as long as the second. Legs black or blackish- 

 brown ; trochanters in part, knees (hind knees very narrowly), base of front femora, 

 front tibia? and base of the four front tarsi, dirty brownish-yellow. 



I beat two $ $ of this species, together with six ? ? and my 

 A. barbatus, described above, from birch at Cannock Chase on 

 May 27th, 1906.

EYDROPORI IOUND NEAR WEST AYTON, YORKSHIRE. 

 BY THE EEV. "W. C. HEY, M.A. 



When I came to reside at West Ay ton seventeen years ago, my 

 searches for Hydropori were singularly unsuccessful, and I was much 

 disposed to write down the region as barren. I am now as much 

 inclined to consider it richer in Hydropori than perhaps any district in 

 Great Britain. West Ayton lies about five miles south of Scarborough, 

 just at the south end of Forge Valley, a picturesque, post-glacial 

 canon of the river Derwent. Within a short distance of my house 

 are low-lying pools, upland moors, with quite a sub-alpine character, 

 large streams, and trickling rills. It is, therefore, not remarkable 

 that after careful research a very large number of species of Hydro- 

 pori have rewarded my labours, as the appended list shows. I include 

 Coelambus and Deronectes.
