FURTHER NOTES ON SAW-FLIES (TENTHRE- 

 DINID^E) FROM THE SUMMIT OF BEN 

 NEVIS, INCLUDING A SPECIES NEW TO 

 BRITAIN. 



By Rev. F. D. MORICE, M.A., F.E.S. 



AMONG the Hymenoptera taken by Mr. Bruce on Ben Nevis 

 in 1895, and reported on in the "Annals" (1896, pp. 165- 

 168) by the Rev. A. Thornley, are some specimens which I 

 determined for Mr. Thornley as Selandria flavescen s, Thorns., 

 and which he consequently recorded under that name. 



Flavescens, Thorns. = flavens, Klug., and the latter name, 

 having the priority, should be adopted. I find, however, 

 what is of more consequence, that the specimens in question 

 are not all of one species. Most of them are correctly 

 referred to S. flavens, Klug., but a few belong to a distinct 

 though very similar species, viz. 6". Wustneii, Konow. 



Wustneii differs from flavens by its thicker antennas, 

 which have the third joint very slightly longer than the 

 fourth. It is also a darker insect, with the clypeus, the pro- 

 notum, and the bases of the antennae quite black ; the costa 

 and stigma, however, are on the contrary lighter than in 

 flavens (brown, not black). 



Selandria Wustneii was first described by Konow in 

 May 1885 (" Wien. Ent. Zeit.," iv. p. 122) from North German 

 specimens. I know no record of its appearance elsewhere, 

 unless the " aberrations a and b " of flavens mentioned in 

 Cameron's "Monograph" (i. p. 196) belong to it; but it 

 may easily have been mistaken for flavens by collectors both 

 in this country and on the Continent. 



Perhaps I may be allowed to take this opportunity of 

 making a few other corrections in the list of Mr. Bruce's 

 captures (I.e. pp. 166, 167), as follows: 



For Tenthredo dispar, Klug., read Tenthredo atra, Linn., var. dispar, 



Klug. 



For Tenthredo viridis, Linn., read Rhogogastera viridis, Linn. 

 For Pamphilius stellata, Christ., read Lyda stellata, Christ. 

 For Dolerus lateritius, Klug., read Dolerus madidus, Klug.
