NEW BEES FROM THE ORIENTAL ZOOLOGICAL REGION. 285 



grey pubescence ; the hinder femora broadly rounded above, transverse 

 below and with a sharp oblique tooth near tbe base of the apical third ; 

 tbe hinder tibiae become gradually dilated from the base to tbe apex. $ . 

 Length, 8 mm. 



Deesa (Col. C. G. Nurse). 



Scape bright yellow, marked above with black towards the apex ; 

 the flagellum fulvous, lined with black above. The face, clypeus and 

 lower part of the front densely covered with pale golden pubescence, 

 which hides the sculpture ; the front is closely, almost rugosely, 

 punctured and covered with dark fulvous pubescence above ; the vertex 

 is more strongly, but not so closely or regularly, punctured ; there is a 

 smooth space on the outer side of the hinder ocelli. Mandibles black, 

 shining, more or less piceous-red below and at the apex. The base 

 of the mesonotum, its apex, the post-scutellum, and the pleurae are 

 densely covered with pale fulvous pubescence. The mesonotum and 

 scutellum are closely, strongly, and uniformly punctured. The area 

 on tbe median segment is closely obliquely striated on the sides ; the 

 centre is more irregularly and more widely striated ; the middle pair 

 of striae are widely separated ; the rest of the segment is closely and 

 rather strougly punctured laterally ; the centre is irregularly rugose, 

 and is hollowed in the middle ; it has a vertical slope. The basal four 

 joints of the front tarsi are fringed with long clear white hair, the 

 hair becoming gradually shorter ; the black on the base of the femora 

 is more extended above ; the tooth on the hinder femora is oblique ; 

 the hinder tibife are slightly dilated at tbe base before the middle; the 

 apical projection is large, and becomes gradually narrowed towards the 

 apex, which is bluntly rounded. Wings hyaline, the apex slightly 

 smoky ; the stigma and costa are dark testaceous ; the nervures paler 

 in tint. Tegulae dirty yellowish-testaceous, black on the inner side. 

 Abdomen black, with distinct bands of depressed greyish pubescence 

 on the apices of the basal five segments ; the basal three segments are 

 strongly and closely punctured ; the apical are closely and rather 

 finely rugosely punctured ; the sixth segment has the apical half 

 covered with lougish pale fulvous pubescence ; the last is thickly 

 covered with long pale golden hair. The basal segment is roundly 

 incised in the middle ; the last is densely covered with longish pale 

 fulvous hair. 



Comes near to N.fervida, Sin., but may be known from it by 

 the different shape of the hinder legs. In fervida, for instance, 

 the hinder tibiae are broadly dilated in the middle behind, and 

 end in a long sharp point ; the base of the femora below is 

 turned upwards, in the present species downwards, there being 

 a gradually rounded curve from the base to the tooth. 



Colletes nursei, sp. nov. 



Black ; the head and thorax thickiy covered with white hair ; the 

 abdominal segments broadly banded with white pubescence on their 

 apices ; the apices of the femora, the tibiae, and the tarsi dark ferru- 

 ginous, and covered with pale fulvous hair ; the wings hyaline, with
