SUMMARY OF ACULEATE HYMEXOPtEKA, 1874 — 76. 63 



3rd of August. I have searched for the species at this 

 locality on many occasions, but without success. The three 

 captures enumerated consisted of males. A period of thirty 

 years now elapsed in the history of the captures of Alacropis, 

 when, in 1874, Mr. Bridgman obtained two males at Brun- 

 dall, near Norwich ; and last summer he succeeded in 

 capturing seven more at the same locaHty. It is certainly a 

 remarkable fact that no one has succeeded in finding the 

 female, and this circumstance might lead to the inference of 

 the habit of the female having some peculiarity not 

 observable in the other sex : this, however, does not appear 

 to be the case. The males captured last summer, at Brundall, 

 were frequenting the creeping thistle, Carduus arveiise ; and 

 both sexes have been captured on that plant in Germany. 

 Leon Dufour took them on Alisma plantago, and Professor 

 Schenck finds them on the leaves of the dewberry, Rubus 

 c<Bsius. Let us hope that it is reserved for Mr. Bridgman to 

 complete the capture of the species by taking the female 

 next summer. 



Panurgus dentipes, Latr., 



is now added to the British list, not by a recent capture, but 

 on the authority of a specimen bearing the locality, Salisbury, 

 which I discovered among the males of P. calcaratus, in the 

 collection of British bees in the British Museum. This 

 species is not rare on the Continent, and will probably be 

 found at the locality mentioned. I had the pleasure of 

 including this species, in the genus to which it belongs, in 

 the second edition of my work on ' British Bees,' recently 

 published by the Trustees of the British Museum. 



Nomada BraDGMANiANA, Smith. 



In the same work will be found described a species of the 

 genus Nomada new to science: Nomada Bridgmaiiiana, 

 discovered by Mr. Bridgman, near Norwich. The species is 

 nearly allied to N. lateralis, and is one of the prettiest 

 species of the genus. 



OsMiA FUCiFORMis, Latr. 



In the work alluded to above, another species, Osmia 

 fuciformiSy is added to the list. In the first edition of the
