EUMENID.S. 167 



in the S yellow, or spotted with yellow in front ; the abdo- 

 men in both sexes, with all the segments broadly banded 

 with yellow, except the apical one, and that in the ? has a 

 round yellow spot. The basal band in the ? is widely 

 dilated at the sides, as in callosus, and the thorax is also 

 much wider in proportion to its length than in trifasciatus, 

 and the clypens has a yellow spot on each side of its base, 

 sometimes connected into a band, whereas in trifasciatus 

 it is almost always entirely black. Sides and apical 

 concavity of the propodeum dull, the former rugose. 



L. 12-16 mm.

0. Antilope, Pans. — About the same size as parieti- 

 nus, and very like that species in colour, but differing from 

 it in both sexes by the shining sides and apical concaTity 

 of the propodeum, and the much shorter costse of the 

 sulcature of the second abdominal segment ; also in the 

 ? by the shape of the band of the basal segment, which 

 is somewhat trisinuate, or rarely simple, not squarely 

 notched in the centre, as in that species, and in having no 

 distinct band on the fifth segment, although in place of it 

 there is often a small central sjDot. 



L. 13-18 mm. 



The largest species of the genus, and separable from any 

 other, as pointed out by Thomson, by the shining sides and 

 apical concavity of the propodeum. 



I do not think this species is common in the South-East 

 of Eogland, at any rate, I have never met with it. It has, 

 however, been taken at Maidstone; (Frishy). Colchester, 

 not uncommon on Raspberry flowers ; (Harwood). Lynn, 

 Norfolk ; (Bridgman). Barmouth, and " common in York- 

 shire ; " {Smith). Oxford and Chippenham; (R. C. L.
