Psocus fasciatus, F., at the Plodda Falls, July 15th. 



Stenopsoous cruciatus, L., common, a large number having the wings much 

 abbreviated. 



CcEoilius obsoletut, SteT^h., common where firs were growing. C.fuscopterm, 



Latr., common at the Dog-fall. C. perlatus, Kolbe, and Burmeitteri, Brauer, 



fairly common on spruce and other firs ; middle of July. C. />»ceuj, Kolbe, a few 



specimens are probably referable to this species. 



JSlipsocus Jlaviceps, Ste., common. E. unipunciatus, two specimens, 



Beauly Koad, July. E. cyanops, Roat., not uncommon about middle of July. 



PKRLID.S.

Isopteryx tripunctata, Scop., and torrentium wore both taken. 



Taniopteryx Eisi, Mort., not uncommon. 



Nemoura variegata, Oliv., and cinerea, Oliv., common. N. inconspicua, 



Pict., was in great abundance wherever there were trickling surface springs. 

 Leuctra sp. ? 



Ephemerid^. 



Leptophlehia Meyeri, Eaton, this species was very common upon the higher 

 moorland. In my 1882 list I recorded Lep. rnarginata, L. This seems to have been 

 an error, as all the specimens which I now have I find to bo the above species. 



Ephemerella ignita, Poda, fairly common. 



Cloeon simile, Eaton, common at Glasslettre, Loch-en-Ang, &c. 



C. rufulum, Miiller, in Glen Cannich. 



Baetis scambus, Eaton, one specimen in the Beauly Road. B. rhodani, 



Piet., the Gull Loch, near Tomich, and in Glen Cannich. B. pumilus, Burm., 



Plodda Falls and in Glen Cannich. 



Rhithrogena semicolorata, Curt., common near Tomich, at the Gull Loch, 

 Knockfin Loch and Glen Cannich. 



Heptagenia sulphurea, Miiller, in Glen Cannich. 



Ecdyurus venoms, Fab., Knockfin, Plodda Waterfall. E. lateralis, Curtis, 



Plodda Waterfall. 



Ccenis sp. ? was seen at the Gull Loch, but not collected. 



Odonata. 



Leucorrhinia dubia. Van d. Lind., was seen south of Tomich, where Mr. 

 Briggs caught one on July 10th. 



Sympetrum striolatum, Charp., not uncommon. <S. scoticum, Don., very 



common towards the end of August on all the high moorlands. 



Libellula quadrimaculata, L., this species was in groat profusion at every 

 little moorland pool. 



Somatochlora metallica. Van d. Lind. This species was first sighted on June 

 16th, flying in a little corrie near Tomich ; it was very difficult to capture then as 

 it flew so wildly and the nature of the ground did not allow of pursuit. On this 

 day I went to the locality whore I had taken it in 1880, but could find no trace of 

 it, and for about fourteen days I constantly visited the locality, but without success. 

 My idea is that when the species emerges it wanders away from its birth-place till
