Hymenopterological Notices. 191 



iJu British Phytophagous Hynienoptera. From any of the 

 -described genera of that group it is to be at once recognised 

 by the great number of joints in the antennae, being six 

 jnore than in Phyllotoma the genus known up till now 

 with the most numerously jointed antennae, namely, sixteen. 

 Phyllotoma^ however, has (like all its allies, the leaf-mining 

 Sawflies) only three cubital cellules, while further there are no 

 cubital cellules in the hind wings. In the form of the antennae 

 undoubtedly it agrees best with Phyllotoma; and, in fact, 

 there is no other genus, except Phyllotoma with which, as 

 regards the antennse, it can be compared. In the neuration 

 of the wings and in bodly structure it almost agrees with 

 Athalia; but Athalia has the antennae at the outside not 

 more than 10 — 1 1 jointed, while further they are sub-clavate 

 in both sexes. On the whole I should consider Hennedyia 

 more nearly related to Athalia than to Phyllotoma ; but its 

 relationship can only be finally settled by the discovery of 

 the ?. 



The genus I dedicate to the memory of my first mentor 

 in natural history, Mr. Roger Kennedy, the author of the 

 Clydesdale Flora. 



Hennedyia Annulitarsis, sp. nov. (PL I. f i — i,^.) 



Nigra, nitida, pronoto, tigulis abdomine pedibusque rufo- 

 testaceis ; apice tibiarum articiilisqiie tarsorum nigris ; alls 

 fusciSy nervis nigris. $ . 



Long, fere 5 mm. 



Antennae longer than the body, filiform, tapering towards 

 the apex, almost bare ; the basal two joints globose, of almost 

 •equal length ; the third joint nearly one-fourth longer than 

 the fourth ; the other joints becoming gradually shorter to 

 the apex ; the third joint slightly curved. Cheeks emarginate, 

 the occiput almost convex ; frontal area not clearly defined ; 

 ~a fovea below the ocelli and there is a smaller one immediately 

 above the antennae. Clypeus convex, a broad and mode-
