Andrena Inpponica, Zett. (Ent. Mo. Maj::., xxxv. p. 2fi2). 



Mr, FT. Elgar was the first recorded captor of this species ; he 

 took it on whortleberry flowers early in May, 1895, at Tghtham in 

 Kent. Since then it has occurred in many localities ; in fact it seems 

 probable that it is to be found wherever its food plant grows. It has 

 been recorded also from Scotland (Evans and Yerbury), Cumberland 

 (Day), Derbyshire (Harwood), New Forest (Nevinson), Leith Hill, 

 near Dorking (Frisby), and N. Wales (Gardner, see p. 213). 



It is closely allied to the other species of the variann group. The ^ having 

 a well developed mandibular tooth can only be confounded with that sex oi fucata, 

 from which its small, entire, labrum (viewed from above), the larger mandibular 

 tooth, and the narrow 2nd subraarginal cell will serve to distinguish it, as well as 

 the very differently formed 7th ventral segment, which is not dilated at the buse of 

 the apical process as xwfucata. 



The $ more closely resembles varians, having the same black-haired face as in 

 that species, from which it differs in being slightly stouter, in having the labrum 

 less transverse and more convex, and the abdomen much less strongly and less 

 densely punctured, especially on the 1st segment, its puncturation agreeing almost 

 with that of fucata. 



Andrena niveata, Friese (Ent. Mo. Mag., xxxv, p. 154), 



This little species was first identified in 1899, and has occurred 

 at Worthing and Bognor and plentifully at Margate. JNliss E. Thoyts 

 took it at Sulhampstead near Eeading, Mr. A. J. Chitty has taken 

 it in the Faversham district, and Mr, E, B, Nevinson has taken it this 

 year in the Fens. 



It is closely allied to A. nana and A. mimitula, but may be dis- 

 tinguished from either of these by the closely punctured apical 

 impressions of the abdominal segments — in nana and minutula these 

 impressions are more or less shining and finely alutaceous, but in 

 niveata they are distinctly, though very Cnel}' and closely, punctured. 

 The $ may be further known by the dense white fimbriae of the sides 

 of the abdominal segments. These, however, are often nearly worn 

 off in specimens which have been long exposed to the weather. 



Cilissa melanura, Nyl. (Ent. Mo. Mag,, xxxiii, p, 229). 



First recorded by Mr. Sladen from St. Margaret's Bay, where he 

 found it on Bartsia odontites in August, 1897. It has since been 

 found by Mr. Elgar at Hailing, Kent, by Mr. Malloch at Rochester, 

 and by Col. Yerbury at Torcross, Devon. 



It is closely allied to leporina of Panzer, but may be easily known in the ^ sex 

 by the longer, entirely black antennae, the joints of which ai'e much more arcuate.
