STUDY OF THE PHRYGANID.E. 55 



tain species often swarm. I took the common Ancibolia 

 nervosa in this way as late as the end of October. 



The remaining families, Rhyacophilides, Leqjtocerides, Hy- 

 drop^ychides, &c.,have ahuost similar habits one with another. 

 They, contrary to the habits of the large LimnophiIides,kc., 

 as a rule shun the vicinity of standing waters, and delight 

 in the banks of rivers and of swiftly flowing streams, and may 

 be found during the day at rest among the coarse herbage 

 and alders, the smaller species often hiding in the crannies of 

 the bark of willows, &c., but at dusk they take wing and fly 

 in swarms, with a dancing motion, close to the water: the 

 long-horned Leptocerides having very much the appearance 

 and habits of Adela and Nemophova, and many of them are 

 quite as handsome. 



Having briefly pointed out the places in which these 

 insects may be caught, I will say a- few words on the manner 

 of capture. Sweeping the banks of streams in the day-time is 

 a very productive method of securing them ; and beating also, 

 in the ordinary way, as for Lepldoptera, will well repay the 

 trouble. In the evening they may, of course, be caught on 

 the wing. When in the net, they are best pill-boxed, taking 

 care to have large-sized ones for the long-horned species, and 

 the gi'eater part will travel safely until the collector reaches 

 home. Dr. Hagen advises pinning at once, but I have a 

 strong objection to pin anything save a Bomhyx, until one 

 can do it carefully and neatly at home. Cliloroform and 

 oxalic acid will soon kill the larger species ; for the smaller, 

 nothing is better than the fumes of sulphur from lucifer 

 matches in a jar W' ith ground edge and plate-glass cover. 



As to the setting : the ordinary rounded manner of setting 

 Lepldoptera is equally applicable to Phryganidoi^ but with 

 this difference, that whereas a refractory leg is often removed 

 in the former, in the latter the leg spurs furnishing th
