(? semi-apterous, as in the type-form, but apparently more slender. The pre- 

 Tailing colour of the body is yellowish, the disc of the head with raised black lines 

 and spots, the pronotum with strong black margins and median line ; abdomen with 

 blackish spiracular spots on caeh side above the lateral suture ; caudal setae yellowish 

 at the base ; legs nearly wholly yellowish, the tips of femora and tibiae, and the 

 tarsi, blackish. (Probably an immature specimen.) 



Length, dry, 10 mm. (much longer when living).

 only (J was taken in cop. by Mr. Jones). We took these examples 

 by sweeping the herbage under the railway bridge, and for a space of 

 a few yards on either side of it. Diligent search for half a mile 

 beyond in either direction failed to produce further specimens, and I 

 could only come to the conclusion that the obstruction to the ordinary 

 current caused by the pile of the bridge had set up a water-condition 

 requisite for the species. No examples could be found under stones 

 near the water's edge, and no cast nymph skins were visible. 



The typical P. Sehjsii is probably peculiar to the Meuse ; I 

 hesitated as to describing the examples from the Moselle as a distinct 

 species, or as only a variety or race. The latter course seems the more 

 prudent, and especially as my materials for the type-form are old and 

 insuiBcient. It is an interesting discovery for the district, and the 

 time of year was very late for any species of the genus in such a 

 locality.

ADDITION OF TWO SPECIES OP HYDROPTILIDM TO THE 

 BEITISH LIST. 



BY J. J. F. X. KINO, F.E.S. 



In the year 1881, while collecting near Ambleside, I captured a 

 number of specimens of a Hyih'optiJa, which I laid aside as a new 

 species, having made drawings of the anal parts. When Mr. Morton 

 was looking over my collection, he recognised the drawings as re- 

 presenting a species recently described by Dr. Ris, under the name 

 H. TiGUEiNA. This species was not uncommon, as I find that I have 

 a number of specimens from the Ambleside district. 



OxTETHiRA Feici, Klap. — I have one specimen of this species 

 in my collection, taken in the Eothiemurchus district a few years ago. 

 For the identification of this I am also indebted to Mr. Morton.
