BKITISH HYDROCAMPIN^ AND SCOPARIANiE. 243 



type, occupying fifth place among the forty-eight species com- 

 prised in it. 



Stenia, Guen., with eleven species, ranks as the thirty-eighth 

 genus ; punctalis, the type, is placed third in order of species. 



Psamotis, Hiibn., which includes Perinephele, has only three 

 known species, i.e. lancealis, pulveraUs (type), and JujaliiiaUs. It 

 is the forty-sixth genus, and is immediately followed by Eurrliy- 

 para, Hiibn., of which urticalis is the only known representative. 



The Scoparianae are a compact little group of seven genera, 

 but only the typical one — Scoparia — is European. This genus, 

 which occupies sixth place in the arrangement, is divided into 

 two sections ; the first comprising one hundred and thirty-two 

 species, and the second only one ; S. cemhrcB is the type. 



In the subjoined list of species found in Britain the number 

 in brackets indicates the position of the species in the genus. It 

 will be seen that hasistngalis, atomalis, ulmella, and conspicualis 

 are sunk in ambigualis ; scotica is removed from zelleri, which is 

 not now considered to be a British species, and is placed with 

 cemhrcB ; freqiientella, Staint., is employed for the species hitherto 

 referred to as mercuriella, Linn., and portlandka is given as a 

 synonym of it instead of phoeoleiica, ZelL, which is deposed, or 

 rather relegated, together with vesuntialis, Gn., to a list of 

 unplaced species ; gracilalis becomes a synonym of alpina. 

 Ingratella, Zell., which is a South European species, possibly 

 ought never to have been included in the British list. 



It will probably be admitted that this revision of British 

 Scojxiria, which agrees with that of Mr. Meyrick except as 

 regards the sequence of species, is in accordance with our present 

 knowledge. There is, however, one species for which a claim to 

 specific rank maybe urged, i.e. basistrigalis. Although I cannot 

 myself see that it differs in any essential character from *S'. 

 ambigualis, I am well aware that several able entomologists 

 consider it to be quite distinct from that species.
