Some European Bees. 



By PROFESSOR T. D. A. COCKERELL, F.Z.S. 



During the past summer, my wife and I collected bees in several 

 European localities, and, although the season was phenomenally poor, 

 we were pleased to see in life many interesting species which we had 

 only known as cabinet specmiens. Our one really good day was at 

 Troyes, in France, on August 8th. It was extremely hot, and we 

 found a railway-bank covered with flowers, over which flitted Pontia 

 daplidice, Colias hi/ale, Pier is brassicae, Vanessa urticae, V. io, and 

 other butterflies. The following bees were obtained :—Panur(/us 

 dentipes, 2 (J , one with head extremely large, constituting a form (var. 

 megacejjhalns, n. vai.) parallel with the variety macroceplialiis of P. 

 calcaratus ; Nomada lineola, Panz., 1 2 ; Ceratina ci/anea, Kirby, 1 ? ; 

 Stelis aterrinia, Panz., 1 2 ', Oswia fuloiventris, Panz., 1 J ; Halictns 

 scabiosae, Rossi, 1 $ ; also another Halictns and a Colletes not yet 

 determined; Anthidium manicatuin var. nif/rithorax, D.T., 2 ^s', 

 Anthidiuw obloni/atinn, Latr., 1 <y , eyes in life, olive-green, with the 

 anterior part reddish-black. 



Anthidiuni, as commonly understood in Europe, includes at least 

 two genera — 



(1) Anthidium, type, J. manicatuin, with no pulvillus, using cottony tomentum 

 in making its nest, and (2) Dianthidium, type, the American D. sayi, having a 

 pulvillus on the feet, and using resin in the construction of its nest. 



Fabre has termed these two groups the "Cotonniers" and the 

 " Resiniers." The subgenus Proanthidiuni, Friese, consists of a 

 mixture of Anthidium and Dianthidium, but I propose to take as 

 the type (none being designated by Friese) the first species, A. 

 nbloniiatuiu, which, though approaching Dianthidium in some respects 

 (especially the venation), is a "Cottonier," and has no pulvillus. The 

 subgenus Pseudoanthidinm (5 species) I have not been able to examine; 

 but Friese's Pavaanthidiu)ii, according to a specimen of A. interruptum., 

 Fabr., in the British Museum, goes with Dianthidium, and having two 

 years' priority, should perhaps supplant it. It represents, however, a 

 quite distinct group, with the clypeus much broader in proportion to 

 its length, and may probably be regarded as a distinct genus. The 

 Paljearctic species usually referred to Anthidium, so far as known to 

 me, may be classified as follows : — 



Anthidium Series. 

 Anthidium, Fabr., 1804 (type manicatuvi, L.). 



(1) manicatum group. 



(2) punctatitin group. 



(3) montanum group.

(5) cingulatum group. 



(6) lituratum group.

(4) septemdentatiun group. 



(5) strigatum gvoxx^ = s,\x\)g. Anthidiellum, Ckll., 1904.
