(Opusc. Eutomol., fasc. xv, p. 159G, 1891) that the mutilated type of 

 Phryganea concentrica, Zett., is Arctoecia dualis, McLach. ; such a 

 determination had been previously made by Hagen {ex descr.), and 

 the (^ of A. dualis has a certain amount of general resemblance to 

 the Ste7iophylax. This corrected identification appears to have been 

 accepted by Wallengren in his " Skaud. Neuroptera,'' Pt. ii {Tri- 

 cJiopterd), 1S91, according to his supplementary note at p. 1(J7- 

 Thomson, having transferred the specific name concentrica, Zett., to 

 the Arctoecia, in place of dualis, McLach., had to find another name 

 for the Stenopliylax, and adopted that of '''' Meroglypliicus, Steph." This 

 was merely the perpetuation of an old error. Owing to circumstances 

 which it is not now necessary to detail, Stephens, when writing his 

 " Illustrations," did not consult Curtis' types, and it happens that 

 Curtis' hieroglyphicus equals Halesus digitatus ; this being so, the 

 Stenophylax must receive a new name, and I propose that of peemistus. 

 As a result, the species known as Arctoecia dualis, McLach., becomes 

 A. concentrica, Zett., as adopted by Thomson.

TEN DAYS' COLLECTINa IN RHENISH PRUSSIA. 

 BT ALBERT H. JONES, F.E.S. 



Having read my friend Mr. McLachlan's article in this month's 

 Magazine on the Neuropterous Fauna of Rhenish Prussia, I am 

 prompted to write a few words on the Lepidoptera observed during 

 our visit. 



We remained three days at Gerolstein, our first halting place, but 

 with the exception of one sunny morning the weather was very bad 

 for collecting — earlier in the season, and in fine weather, no doubt the 

 district would be very productive. 



About two miles in an easterly direction from the town lies an 

 extensive forest, principally consisting of fir, the ground being car- 

 peted with Vaccinium. An excursion to an elevation of about 1900 

 feet (i. e., 600 feet above Gerolstein) revealed a grand view over hills 

 covered with an uninterrupted forest to the east, and to the west over 

 more open and cultivated country. About three miles off, near the 

 village of Roth, lies the " Ice Cave,"* situated on a volcanic hill 

 covered with beech trees of large dimensions among lichen-covered 

 boulders. This locality had all the appearance of being good collecting 

 ground for Lepidoptera. 



* So called because a thin layer of ice on the rock never melts all the year round.
