bo TRANSACTIONS OF THE 



niger from Loch Duich. Also the following saw-flies :- — Both sexes 

 of Ccenoneura BaJdbomi, taken in Cadcler Wilderness ; the male of 

 this species has hitherto been xmdescribed. A species new to 

 science, which he has named Nematus Vollenhoveni after the 

 talented Dutch entomologist, to whom we owe much of our present 

 knowledge of the life-histories of saw-flies, more particularly those 

 of Holland. A full description, together with an account of its 

 habits and metamorphoses, appears in the "Scottish Naturalist." 

 (vol. II,, p. 296 et seq.) A number of the galls and living larvae 

 were also exhibited. Dr. Stirton pronounced the small tubercular 

 elevations, which often broke up the surface of the galls, to be 

 the work of a minute fungus. 



EXCURSIONS. 



Spout of Ballagan. — Owing to the unfavourable character of the 

 day, very little of interest was done. The members, after leaving 

 the glen, visited the Blairquosh oak and measured it. The 

 minimum girth was found to be 16 feet Scinches. In a list of 

 remarkable trees which appeared in an old volume of the '"'Citizen" 

 newspaper, the girth of this tree was stated to have been 1 5 feet in 

 1796. 



Fin Glen, and the Earl's Seat. — In the Ein Glen a number of 

 interestiag plants were observed, from which the following may 

 be selected for mention: — Arahis hirsuta, Ruhus chamcemorus,
