INSECTA SCOTICA, 



THE TRICHOPTERA OP SCOTLAND. 

 By JAMES J. KING and KENNETH J. MORTON. 



IN order to maintain the uniformity of the catalogues of the 

 " Insecta Scotica " we have, in the following list of 

 Trichoptera, followed the plan of the catalogues of Lepidoptera 

 and Coleoptera, by Drs. Buchanan White and Sharp respectively, 

 published in the earlier volumes of the "Scottish Naturalist." At 

 page 161 of vol. i., first series, will be found full details of the 

 thirteen divisions into which the country is divided, for the pur- 

 pose of indicating the distribution of each species ; but as this 

 volume may not be in the hands of some, it may be well to repeat 

 these divisions here.
