OBSERVATIONS ON HYMENOPTEROUS PAPERS, ETC. 93 



rescued the Oxybelus bipunctatus from the suspicion which 

 has so long hung over it; Mr. Dale took it at Bourne- 

 mouth, Hants. 



Eumenes coarctata (Fam. Vespidce). Mr. E. Shepherd 

 took this very local insect at Addington Wood, the nearest 

 locality to London with which I am acojiainted. 



JProsopis dilatata (Fam. Andrenidce). I again captured 

 this little bee at Pakefield, near Lowestoft, in July last, and 

 also succeeded in rearing the species from a perforated stick, 

 which I obtained at the same locality in 1848, the female not 

 being previously known ; that sex proves to be the P. annu- 

 laris of Kirby; the male, which that author united with 

 the latter, being the male of my species P. hyalinatus, 



Andrena eximia (Fam. Andrenidce). This beautiful 

 species was taken in the spring, near Exeter, by Mr. J. 

 Truscott. 



S tells aterrima (Fam. Cuculince). This rare species was 

 observed in great abundance by Mr. B. Newcome, in his 

 own garden, at Sutton Cottage, near Dartford, Kent ; not 

 being aware of its rarity, he only captured two or three 

 specimens. 



Osmia xanthomelana (Fam. Dasygastrce). Taken by 

 Mr. B. Newcome at the above locality. I have once or 

 twice taken it near Birch Wood ; it also occurs at Shanklin, 

 Isle of Wight, and near Exeter. 



As the last notable capture, I may mention a new species 

 of Jlemiteles, belonging to the family Ichneumonid.ce; it 

 has been lately described by Mr. Desvignes, and named 

 Jlemiteles formosus. This insect is parasitic upon a species 

 of spider, Agelena brunnea; this little Arachnide constructs 

 a nest of snow-white silk, which it afterwards overlays with
