DESCRIPTION OF A NEW SPECIES OF PSEUDAGENIA. '223 



Hab. One female, Parry Harbour, C. Bougainville, 92. 4 : 

 six males, Townsville, Queensland, 8. 12. 01 (P. P. Dodd) ; 1902. 

 319. The colour is uniformly very different from that of N. 

 flavoviridis, but there are no satisfactory structural characters. 



Nomia rubroriridis, n. sp. 

 ? . Length about 1(H mm., rather broad; black, the hind mar- 

 gins of the first four abdominal segments with very broad entire 

 emerald-green bauds, the first two being suffused on their anterior 

 half with vermilion ; the fifth segment has a dense fringe of ochreous 

 hair, and the apical segment is covered with the same. Sides of face, 

 area between antennae, cheeks, prothorax including tubercles, pleura, 

 post-scutellum, and nearly all of metathorax covered with coarse 

 sordid-white, more or less tinged with ochreous ; a delicate raised line 

 extends down middle of face to apex of clypeus ; antenna? dark ; man- 

 dibles with the subapical region dark red, the apex feebly bidentate ; 

 mesothorax dull, with dense small punctures ; scutellum also dull, 

 slightly depressed in the middle, but not tuberculate or spined ; post- 

 scutellum with a prominent bifid median process, directed backwards, having 

 much the shape of a fish-tail, ; tegulae large, the inner hind corner 

 pointed, the base fuscous, the middle ferruginous, the outer hind part 

 broadly creamy white ; wiugs somewhat dusky, stigma and nervines 

 dark rufo-fuscous ; second submarginal cell fairly large, a little higher 

 than broad, receiving the first recurrent nervure much before its end ; 

 legs black, with pale pubescence ; anterior spur of hind tibia longer than 

 the other, stout and nearly straight, with a little divergent reddish spine 

 arising from the side of its apex ; hind spur curved, simple ; black parts 

 of abdomen dull, only moderately punctured ; hind margins of ventral 

 segments dark and fringed with hair. 



Hab. Australia, north-west coast ; 69. 50. A very distinct 

 and beautiful species, superficially resembling a small Anthophora 

 of the zonata group, with which, in fact, I had accidentally 

 mixed it. It is not precisely a Hoplonomia, but it is probable 

 that the diagnosis of that group should be modified to permit its 

 inclusion. In the colour of the abdominal bands it strongly 

 recalls N. opulenta, Sm., and N. elegans, Sin., from Morty Island 

 and Celebes respectively.

DESCRIPTION OF A NEW SPECIES OF PSEUDAGENIA 



(HYMENOPTERA— POMPILIDjE) FROM NATAL. 



By P. Cameron. 



PSEUDAGENIA NATALENSIS, Sp. 110V. 



Black, the prothorax, except the sternum, mesonotuin, scutellum, 

 the mesopleurae above the oblique furrow at the base and slightly 

 below it, the post-scutellum and a line on either side of it, reaching to 

 the pleurae, rufous; the sides of the first abdominal segment testaceous;
