T. D. A. COCKERELL. 233 



disc of mesothorax short and dark fuscous, dense and ochreous on 

 upper border of prothorax and on tubercles, very dense and fulvous on 

 postscutellum ; head broad ; mandibles dark, the extreme apex ferru- 

 ginous ; scape long, black ; flagellum black at base, beyond with a 

 dusty appearance, the apex red beneath ; face and front malleate, with 

 large dense shallow punctures, while on the mesothorax this is modi- 

 fied into a cancellate sculpture, the depressions separated by fine 

 ridges, the general effect without high magnification being that of a 

 very coarsely roughened dull surface ; area of metathorax dullish, with 

 a very coarse open network of raised lines, the longitudinal rugae more 

 numerous and prominent than the transverse ones ; pleura rough ; 

 posterior face of metathorax finely grayish pruinose ; tegulse shining 

 rufopiceous ; wings slightly dusky, stigma and nervures reddish-sepia ; 

 second s. m. rather broad, but much smaller than third, receiving first 

 r. n. well before the end ; outer nervures scarcely weakened ; legs 

 black with yellowish hair, the tarsi more or less ferruginous ; hind 

 spur with a few very large teeth ; abdomen with bands of dense fulv- 

 ous tomentum at bases of second and third segments ; first segment 

 delicately punctured at sides, but scarcely at all in middle ; second and 

 third finely and closely punctured all over; caudal rima fulvous, with 

 brown hair on each side ; much orange pollen collected on hind femora 

 and basal half of abdomen beneath. 



Evidently related to the H. bicivgulatus group, but easily 

 known by the small size, dark legs, and peculiar sculpture of 

 metathorax.

Halictus maitlandi sp. nov. 



9 . Length about 7 mm., robust, superficially similar to H. stir- 

 litigi, but structually very different ; black, head, thorax and abdomen 

 dullish, with a sericeous lustre ; hair of head and thorax pale, very 

 scanty, except that the tubercles, adjacent lateral lobes of mesothorax, 

 and the postscutellum, are very densely covered with fulvous hair ; the 

 sides and truncation of the metathorax also have much pale hair ; head 

 broad, the scanty hair of face yellowish ; mandibles dark, a little red- 

 dish at base ; scape red, black at apex, flagellum black ; front with a 

 microscopic tessellate sculpture running into fine lineoles, under a lens 

 having a dullish submetallic sheen ; mesothorax impunctate, under a 

 high power of the microscope densely covered with minute file-like 

 striae ; scutellum like front, and with a few minute punctures ; area of 

 metathorax large, dull and granular; tegulse ferruginous, with some 

 fulvous hair in front ; wings rather dusky, the marginal cell and apical 

 field beyond clouded with dark fuscous ; stigma and nervures pice- 

 ous ; second s. m. larger than third (third remarkably short), first 

 r. n. joining second t. c, b. n. less bent than usual; femora black,
