198 THE ENTOMOLOGIST, 



Halictus rubicundus, H. cylindricus, H. albipes, H. flayipes, 

 H. mono, H. villosulus, H..iiniiutus, and Andrena Afzeliella; 

 males of several species of Bombi were also observed. 



Three examples only were captured, at Walmer, of the 

 beautiful Andrena Hattorfiana, the largest and handsomest of 

 our native species of the genus : sixty-eight species of these 

 bees are described, and about six remain to be added to the 

 list ; in the recent work by Mr. Shuckard fifty-two are said 

 to inhabit this country : we are also told by the same author 

 that " none of the Andrenidae exhibit any positive colouring 

 of the integument, excepting in some upon the abdomen:" 

 this holds good as regards the species of this country, but a 

 series, including all ihe known species of the genus, presents 

 us with some having the thorax red above, one entirely of 

 that colour, whilst others are adorned with tints of blue, 

 varying in depth of colouring in different species. 



The only bee remaining to be noticed is the Osmia fulvi- 

 ventris, which appeared in unusual abundance at Kingsdown, 

 near Deal ; it was frequenting the flowers of a species of 

 hawk-weed. This bee usually burrows in posts and rails, 

 but here I noticed it burrowing in an upright hard clay bank 

 of a gravel-pit ; I also observed Stelis aterrima entering its 

 buiTows. 



Having been charged with robbing a brother Entomolo- 

 gist of his just rights to distinction, as being the first to 

 capture a species of the genus Osmia, I will state here my 

 own knowledge of the subject : the charge relates to the 

 discovery of Osmia pilicornis. 



This species was first taken by Captain Blomer ; subse- 

 quently by Dr. Thwaites on the slopes of Durdham Downs: 

 this gentleman distributed it among his entomological friends 

 under the manuscript name of O. pilicornis : Mr. Walcott 

 has also repeatedly taken it in Leigh Woods, near Bristol ; 

 and 1 once captured two examples at Birch Wood, Kent : 

 these are all the captures with which 1 am acquainted. Mr. 

 Bainbridge, who is said to have first taken it, was well 

 known to me, and from him 1 have obtained several rare 

 species of Coleoptera ; but I never became aware of his 

 having taken the Osmia pilicornis, and, if so, 1 feel confident 

 that both Captain Blomer and Dr. Thwaites preceded him, 

 and that the latter gave the manuscript name to the species.
