l86 HYMENOPTERA ACULEATA. 



and tte tarsi at their base more or less yellow ; ? witli 

 the base of the posterior tibi5e only of that colour. 



L. 6-7 mm. 



Common and generally distributed, usually occurs on 

 bramble flowers. 



Eupestris, Smith, of which I have examined the type, 

 is clearly referable to this species. 



P. signata, Panz. — Considerably larger than the pre- 

 ceding, black, head and thorax punctured, face, across the 

 eyes, wider than long, white below the antennae in the c?, 

 black in the ? , generally with a narrow yellow spot on 

 each side near the margin of the eye, scape of the antennae 

 in the S slightly curved, thickened at the apes ; pronotum 

 with a spot on each side of the collar and the tubercles 

 yellow, wings hyaline, propodeum finely and clathrately 

 rugose; abdomen dull and strongly punctured in the c?j 

 shining and finely punctured in the ?, both sexes with a 

 lateral line of white pubescence at the apex of the basal 

 segment, and with fine greyish hairs on the sides and

 point, armature with the stipites fringed with long hairs 

 rounded at the apex, longer than the sagittse ; extreme 

 base of the tibiae and tarsi in the <S yellow. 



L. 7-8 mm. 



On flowers of bramble, mignonette, &c., July and 

 August. Mr. V. R. Perkins has met with this species 

 burrowing in hard clay banks, and also once found a colony 

 breeding in the mortar of the stone wall of his garden. 



P. puuctulatissima, Smith. — Very like siijnata but 

 rather smaller, and easily distinguishable by its elongate 

 face, which is longer than its width across the eyes ; also
