/b HYMENOPTERA. 



excepting in the neuration of the wings ; it is a little more 

 pubesceni about the head and thorax ; the neuration of the 

 wings of P. m'ger varies greatly, the third submarginal cell 

 is sometimes triangular, petiolated, or, occasionally only con- 

 tracted towards the mariiirial cell, but I have never seen a 

 specimen of J*, niger agreeing with Mr. Bold's insect; it 

 would be very desirable that a series of specimens should be 

 obtained, including the male sex, when some strong specific 

 character might be found, and the insect satisfactorily deter- 

 mined as a new British species, which I am inclined to con- 

 sider it ; I cannot find any description of an European Pom- 

 pilus that suits it. 



Having visited Cromer in August last, I will give a list 

 of such aculeate Hyraenoptera as I noticed in that extreme 

 north-east corner of Norfolk ; it is true, that in consequence 

 of the long-continued summer weather that preceded my 

 visit, the list will give, probably, a very inadequate idea of 

 the species usually to be found there in the month of August, 

 but I know no work that contains any account of the ca|)ture 

 of a single flymenopterous insect from Cromer. Many 

 Coleoptera have been registered as occurring there, and, if I 

 may draw my conclusions from the general character of the 

 neighbourhood, I should certainly say it is a locality rich in 

 its Hymenopterous fauna. The beautiful hills, valleys, 

 woods and open commons, that diversify the surrounding 

 country, offer every kind of situation usually resorted to by 

 the aculeate Hymenoptera.
