[There is much yet to be learned with respect to the presumed varieties, based 

 on colour characters, of Philopotamus montanus. I have already pointed out (Rer. 

 and Synop. of European Trichoptera, p. 383) that Donovan's original figure of 

 montanus resembles the var. scoticus rather than what we are accustomed to consider 

 the " type " form. Then again there are the vars. chrysopterus (Morton) from 

 Clydesdale, and cesareus (McLach.) from Jersey. Also the very striking form that 

 I ventured to consider a distinct species, and described as insularis, from Guernsey. 

 The presumed var. cesareus appears to be peculiar to Jersey to the exclusion of any 

 other form of the species. The presumed species insularis appears equally peculiar 

 to Guernsey, and exclusive there. But the presumed vars. chrysopterus and scoticus 

 are in a somewhat different position. They are only isolated, inasmuch as they seem 

 exclusively confined to certain streams within easy distance of localities where the 

 so-called " type " occurs in abundance but without the vars. I bring these points 

 prominently forward because they are fraught with importance. There is much yet 

 to be learned. — R. McLachlan.] 



Apatania muliehris, McLach. — Towards the end of August, during a short visit 

 to London, I spent a day at Arundel in search of Apatania muliebris, McL., having 

 had the locality indicated to me by Mr. McLachlan. Since his last visit it has 

 been considerably changed, retaining walls for a mill pond have been erected, and 

 the miniature waste-fall has been destroyed, but, notwithstanding the above serious 

 alterations in the surroundings, I might have obtained any number of the species, at 

 least, the $ , for as yet the $ has not been taken. — Id. 



[It is interesting to find that A. muliehris still holds its own, without the 

 apparent necessity for a husband, in the old locality, notwithstanding changes in its 

 very limited habitat. I have previously detailed my numerous visits to this locality, 

 in former times, in the hope of finding the (J . — E.. McLachlan.]
