ON THE FLORA OF TIREE 81 



For Dohrus pratensis, Thorns., read Dokrus pratensis, Linn. 



Dolerus elongatus, Thorns., is considered by Konow to be only a 

 variety of czneus, Htg. 



Dineura virididorsata = Dineiira nigricans, Christ. 



Nematus acuminatus, Thorns. I had some doubt about my identi- 

 fication of the c? of this species, but Herr Konow tells me it is 

 correct. 



As the whole genus (or rather group of genera) Nematus 

 is in process of revision by Herr Konow, and many altera- 

 tions in its synonymy may be expected, I do not think it 

 worth while to revise my provisional determinations of Mr. 

 Bruce's specimens at present.

 (Continued from p. 38.) 



POLYGALA VULGARIS, L. Rare ; Salum Bay, a few plants. 



POLYGALA SERPYLLACEA, Wet he. Common ; prostrate on exposed 

 sandy ground. 



SILENE MARITIMA, With. Common, but rather local ; most plentiful 

 on sand dunes ; occurs also on rocks and sea cliffs, in the 

 latter place being larger and more luxuriant. 



LYCHNIS DIOICA, L. Rare ; among rocks at Kenavara and Hynish 

 Head. 



LYCHNIS FLOS-CUCULI, L. Common in damp pastures. 

 CERASTIUM TETRANDRUM, Curtis. Very common in sandy places. 



CERASTIUM GLOMERATUM, Thitill. Common ; mostly by roadsides, 

 waste places, and cultivated fields. 



CERASTIUM TRIVIALE, Link. Very common everywhere, except in 

 the central moorish ground and salt marshes. 



STELLARIA MEDIA, Cyr. Very common among cultivation and in 

 waste places ; occurs also in crevices of rocks at Cliad cliffs 

 where cattle and sheep frequent, and on the floor of caves at 

 Kenavara Head, which these animals cannot reach, but which 

 are much frequented by rock doves and starlings. The plant 

 has probably been at first brought to these caves by birds,
