Ephemerid^. 

 Leptophlehia marginata, Lin., Cross Craig Burn, two specimens ; suhmarginata, 

 Steph., Cross Craig Burn, two specimens ; *Meyeri, Etn., on the moor above the 

 Black Wood, common. 



*Ameletus inopinatus, Etn., one specimen on the sandj spit at the mouth of the 

 Dall Burn was taken by Mr. Briggs. 



Siphlurus lacufttrix, Etn., a few were taken. 



Ecdyurus venosus, Fab., a few were taken : lateralis. Curt., a few were taken. 



Odonata. 



Leucorrhinia dnbia, Lind., was not uncommon at two or three localities, but, as 

 usual, males were rather difficult to catch. On June 11th and 12th the ? s were 

 found drying their wings near a little loch above the Black Wood, near which we also 

 found the empty skins of the nymph. 



Libellula quadrimaculata, Linn , as usual very common everywhere. 



Somatochlora arctica, Zett. This species was obtained in the Black Wood, 

 flying south fi-om the direction of the loch towards the higher ground ; over a 

 dozen specimens were taken in all. 



Cordulegaster annulatus, Latr., as usual, common. 



JEschna ecerulea, Strm. {borealis). With hard work this species was obtained 

 in numbers ; we all found that it is inclined to be inquisitive, one specimen alighted 

 in my white net, and another settled on Mr. Briggs' face. This has been observed 

 before by Mr. Morton, when in the Glen Lochay district. Juncea, Lin. A curious 

 specimen, so much like a ccerulea that it may be a hybrid, especially as no other 

 juncea occurred to any of us, and it was early for the species. 



Pyrrhosoma minium, Harr., common. 



EnaUagma cyathigerum, Charp., common. 



PLANIPENNIA. 



Sialis lutaria, Linn., common ; fuliginosa, Pict., Mr. Briggs obtained this by 

 sweeping at a small stream near the Black Wood. 



Hemerof)ius inconspicuus, McL., Black Wood, one specimen ; nitidulus, Fab., 

 common ; micans, Oliv., common ; humuli, Lin., one specimen by beating ; limlatus, 

 Wesm., common ; nervosus, Fab., fairly common ; *Mortoni, McL., two specimens 

 by beating in the Black Wood were obtained by Mr. Morton. 



Coniopteryx psociformis, Curt., aleyrodiformis, Steph., both species fairly 

 common in the firs. 



TEICHOPTEEA. 



Neuronia rujicrus, Scop. This species was found flying in the sunshine upon 

 the moor, and was also beaten out of the fir trees, not uncommon. 



Phryganea obsoleta, McL. A few specimens were taken at a loch above the 

 Black Wood. 



Colpotaulius incisus, Cnrt., was obtained by sweeping at night in the low marshy 

 ground between Camachgouran and the loch. 



Grammotaulius atomarius, F., taken along with the last species. 



LimnophUits Jlavicornis, F., was taken in the same ditch as the two previous 

 species ; elegans, Curt., two specimens of this scarce species were obtained by beating
