66 Mr. F. Smith’s descriptions of new species of 
*929, Nomia cinerascens. 
Male.—Length 2? lines. Black, and thinly covered 
with cinereous pubescence, that on the face being pale 
golden. The flagellum of the antennz fulvous, except 
the basal joint, and slightly fuscous above. Thorax: the 
post-scutellum with short, white pubescence; the wings 
hyaline and brightly iridescent ; the nervures pale testa- 
ceous; the anterior tibiz in front and all the tarsi pale 
rufo-testaceous ; the posterior femora not dilated. Abdo- 
men gradually widened to the apex, which is pale testa- 
ceous, the margins of the segments depressed, somewhat 
testaceous, and with pale pubescent fasciee. 
Hab.— Natal. 
*30. Nomia producta. (PI. II. fig. 16, $.) 
Male.— Length 53 lines. Black: the pubescence cine- 
reous; the clypeus greatly produced forwards, to nearly 
half the length of the head, its apex, as well as the 
labrum, white. Thorax: the wings hyaline, with a 
darkish-fuscous cloud beyond the enclosed cells, which 
extends to their apical margins; the legs obscure fusco- 
ferruginous; the posterior femora slightly ‘dilated: the tibiae 
curved, widened at their apex, which is produced into 
an elongate, pale-testaceous, scale-like process. Abdomen 
elongate and widened towards its apex, covered with a 
slightly fulvous pile, the apical margins of the segments 
with bright silvery-white fasciz, observable in certain 
lights, the margins being narrowly testaceous. 
Hab.—Natal. 
*31. Nomia serratula. 
Male.—Length 3? lines. Black: the apical margins 
of the segments of the abdomen bright rufo-testaceous ; 
the entire insect closely and strongly punctured. Head, 
below the insertion of the antennz, covered with cinereous 
pubescence. Thorax: the legs obscurely rufo-piceous, 
the tarsi palest; a cinereous pubescence on the legs as 
well as on the thorax beneath and on the sides; the 
posterior legs not swollen, their tibiz serrated exteriorly; 
wings subhyaline at their base, with a fuscous cloud 
beyond the stigma, and brightly iridescent; the nervures
