Hab.: Ceylon, Kandy ; alt. 1900 ft. (25.V.08, by beating in 

 jungle in evening). 



The genus Articero'psis Wasm. has hitherto contained a single 

 species, A. sikorae Wasm , from Madagascar. This one from Ceylon 

 now added agrees well with A. sikorae in many points, but can be at 

 once distinguished from it by the form of the fourth joint of the 

 antennae. Probably when we have more knowledge of the Oriental 

 species, it will require to be separated.

ANDBENA FALSIFICA n.n. FOE A. MOBICELLA ? , nec J . 

 BY R. C. L. PERKINS, D.Sc, M.A., F.E.S. 



In my paper on the Andrena minutula group published in this 

 Magazine (April and May, 1914), I distinguished a new form, which 

 I named moricella, specially selecting the ^ as type, since I felt 

 uncertain whether the ? described under the same name really 

 belonged to the same species. 



This ? , as I have now discovered, was not the other sex of 

 A. moricella, and so I have named it A. falsi fica, and the specific 

 characters of its true ^ , previously unknown to me, are given below. 



The ? which, as I now believe, should have been assigned to ^ 

 moricella is excessively like that of A. aJfkeuella, so much so as to 

 suggest to my mind that, in spite of the extreme dissimilarity of their 

 (J (^ , these two forms may be spring and summer generations of a 

 single species. As some of the characters given for $ alfkenella are 

 not always distinct in moricella, my table (op. cit., p. 74) may be thus 

 modified : —
