Some New Genera and Species of Hymenoptera. 243 



scopa dark fuscous. Pygidium densely covered with stiff depressed 

 fulvous pubescence, which gives it a striated appearance ; the centre 

 is furrowed. 



The tegulae are large, conchiform, piceous or pale on the outer 

 edge ; the occiput almost transverse ; the metanotum is shorter and 

 has a steeper slope than usual ; the abdomen is also shorter than 

 usual compared with the thorax. The insect is broader and stouter 

 than usual.

NOMIA DALYANA, Sp. nOV. 



Black ; the head, thorax, and base of abdomen covered with long 

 cinereous pubescence ; the abdominal segments banded with de- 

 pressed pubescence of the same colour slightly tinged with fulvous ; 

 the last segment ferruginous, its sides covered with pale golden 

 pubescence ; legs fulvo-rufous, all the coxae, trochanters, the fore 

 femora above and below, the middle entirely, the hinder broadly 

 above and a large mark on the basal half of the middle tibiae on the 

 outer side, black ; wings hyaline, tinged with fulvous, the apex of

The male hind femora are greatly swollen, broadly rounded above, 

 straight below, with a short, stout, oblique tooth in the middle ; the 

 hind tibiae narrow at the base, becoming gradually wider towards the 

 apex, which, on the lower side, is produced into a bluntly rounded 

 process, more than twice the width of the base of the metatarsus, 

 which is simple, of uniform width, and not longer than the other 

 joints united. Antennae black, the scape covered with long fulvous 

 hair. Head closely punctured, more strongly, rugosely on the front. 

 Mandibles fulvo-testaceous, black at the apex. Thorax more strongly 

 and not quite so closely punctured as the head ; the scutellum slightly 

 depressed in the middle. Metanotal area clearly defined by a keel 

 behind, strongly but not closely striated ; the segment behind it closely 

 rugosely punctured. Abdomen closely and strongly punctured, the 

 second segment and, to a less extent, the third depressed at the base ; 

 the bands under the pubescence are lead-coloured. Tegulae piceous. 



The female similarly coloured ; the hind femora and tibiae not 

 dilated ; the pubescence on the legs denser and longer ; the femora 

 not toothed. 



Comes near to N. calida, West. ; the two may be known, inter alia, 

 by the different shapes of the hinder legs ; in Daly ana the hind
