146 MR. BOLD ON THE ACULEATE HYMENOPTEEA 



4. P. plumbeus, Fab. Dahlb., Hym. Europ., I., 42, 21, and 



444, 3 ; Smith, Monog., 58, 5. 



Apparently confined to the sea coast. It is common on the 

 sand-hills near South Shields, from July to September. 



5. P. niger, Fab. Dahlb., Hym. Europ., I., 45, 24; Smith, 



Monog., 59, 6. 



Not an abundant species with us. I have specimens of both 

 sexes, taken near Featherstone, in July ; and others from Na- 

 worth and Lanercost. It is a most active creature, and the 

 females sting very painfully. The nest is provisioned with cater- 

 pillars. 



6. P. melancerius. Van D. Lind. Dahlb., Hymn. Europ., 



I, 46, 25 ; Bold, Entom. Mon. Mag., IV., 226. 



This species, which is new to Britain, was captured by the 

 Irthing side, a little to the west of Gilsland, in July. It appears 

 to be very rare ; my specimen, a female, and another of the 

 same sex, taken near Dumfries, are the only British examples 

 known. 



7. P. {Priocnemis) sepicola, Smith. Smith, Monog., 63, 10 ; 



Priocnemis fuscus, Dahlb., Hym. Europ., I., 102, 46. 



Not uncommon about Haltwhistle, Naworth, and Lanercost, 

 at the end of June. It is said to prey upon spiders. 



8. P. {Priocnemis) exaltatus, Fab. Smith, Monog., 65, 13 ; 



Priocnemis exaltatus, Dahlb., Hym. Europ., I., 113, 55. 



An abundant species in most parts of the country, but has 

 only occurred sparingly within our district. 



9. P. (Priocnemis) agilis, Shuck. Shuck, Foss. Hym. App., 



251, Var. B. P. exaltatus, 67; Smith, Monog., 66, 14. 



Rare ; only one specimen, a female, having been taken, the 

 exact locality of which I had omitted to note.
