strongly and closely longitudinally striated; the wings 

 hyaline, highly iridescent, and slightly infuscated towards 

 the apex; the stigma and nervures are dark fuscous. (J.

Antennai black, brownish towards the apex. Tlie fjice, 

 clypeus, and the lower outer orbits are tliickly covered with 

 jjale fulvous jnibcscence ; the hair on the front and vertex is 

 sparser and paler in colour ; the front and vertex are aluta- 

 ceou?. The apex of the clypeus is broadly rounded ; the 

 labrum is fringed with golden hair and has two rounded 

 broad keels, the lower being smaller than the upper. Man- 

 dibles piceous. Mesonotum and scutellum closely punctured, 

 their hair is moderately thick and long and pale golden. The 

 area on the median segment is large, extends to the top of 

 the apical truncation, and is, except at the narrowed apex, 

 closely, strongly, longitudinally striated j the sides on the 

 apical slope are keeled. The hinder tibia? and tarsi are not 

 dilated. Abdomen shining, impunctate; the apices of the 

 basal four segments aie paler and are thickly covered with 

 golden pubescence, which hides the surface ; the last segment 

 is brownish, and is thickly covered with long fulvous mixed 

 with black hairs. The ventral surface is more or less piceous 

 and is thickly covered with long pale hair. 



Nomia carinicoUi's, sp. n. 



Black, the pubescence white ; the apices of the segments 

 covered with white pubescence ; the wings short, hyaline, 

 the stigma and nervuies pale testaceous j the area on median 

 segment irregularly reticulated in the middle, the sides 

 obliquely striated. ? ,

IJab. Ceylon {Rothney). 



Face and clypeus thickly covered with white pubescence, 

 the pubescence on the front and vertex sparser ; on the outer 

 orbits it is dense. The base of the pronotura is margined by 

 a sharp keel; behind this it is closely minutely punctured. 

 Mesonotum closely, uniformly, and distinctly punctured ; the 

 scutellum is less distinctly punctured ; both are covered, but 

 not thickly, with white short pubescence. Postscutellura 

 more thickly covered with longer white pubescence. The 

 basal area on the median segment is irregularly reticulated ; 

 the sides are obliquely striated, but not closely; the upper 

 third of the apical slojie has a narrow furrow, the furrow on 

 the rest is wider and deeper. The legs are brownish testa-
