McLachlan, “ Revision and Synopsis,” pt. viii., describes 66 species as 
pertaining to the European fauna, 40 of which are included in the genus 
Rhyacophila. 
The habits of the larvae of two forms of this family occurring in South 
Brazil are noticed by Fritz Muller, Tr. E. Soc, 1879, pp. 140 & 141. 
One of these lives, almost without any case, between the tangled stems of 
water-plants ; the anterior legs of the larvae are armed with curious, power- 
ful forceps ; the cocoon of the pupa is not protected by a regular case. 
Smaller species of another genus build portable cases agreeing with those 
of most of the HydroptilidcB in not showing any difference between the 
two extremities ; in one of them the water gains access by a small 
upright cylindrical chimney in the middle of the Jcase, in another by 
small openings along the dorsal side.
