NOTES ON THE ENTOMOLOGY OF POKTUGAL. 



VI. SYMENOPTERA ACULEATA, 



Collected by the Key. A. E. Eaton in 1880. 



BY EDWiED SAUNDEES, F.L.S. 



In recording the species of Aculeate Hymenoptera captured by 

 the Rev. A. E. Eaton, I am glad to be able to notice many species of 

 considerable rarity and interest, including 4 that I believe are new to 

 science, and which I have described in the following notes. The col- 

 lection contains altogether 79 species, and of these 28 occur also in 

 Great Britain. Dr. Perez, of Bordeaux, has kindly examined some of 

 the difficult species of Andrena, &c, for me, and many of them bear 

 his names, some of which, I believe, are still unpublished, but likely 

 to appear in a forthcoming work. 



FOSSORES. 



Mutilla stridula, Rossi. — One $ , May 8th, at Almodovar. 



Bhilanthus triangulum, E. — One <$, May 23rd, on the hillside 

 near Sao Marcos de Serra. 



Cerceris arenaria, L. — One $ , May 15th, in a vineyard to the 

 north of Silves. 



Hoplisus latifrons, Spin. — One $ , May loth, in a vineyard to the 

 north of Silves.

 Silves to Monchique. 



DIPLOPTERA.

 , the other at Cintra. 



V. sylvestris, Scop. — Two £ ; one, June 24th, westward of Villa 

 Real, the other, June 14th, hillside near Ponte de Morcellos. Both
