 ceous, wings fusco-hyaline, the nervures testaceous. Abdomen 

 ovate, delicately but very closely punctured, margins of the seg- 

 ments testaceous, each having a band of white pubescence more

97. Halictus fuscipennis, n. s. B.M. 



Female. Length 4 lines. — Black, the head and thorax closely 

 punctured, the clypeus having a few elongate deep punctures at 

 its base, the anterior margin fringed with ferruginous hairs. 

 Thorax, the wings fusco-ferruginous, the posterior pair paler at 

 their base, all the tibite and tarsi ferruginous, the metathorax 

 truncate, the superior margin of the truncation ridged, the en- 

 closed space below the post-scutellum rugose. Abdomen very 

 finely and closely punctured, the basal segment shining; the 

 basal margins of the second, third and fourth segments have an 

 interrupted fascia of pale fulvous pubescence. 



Male closely resembles the female ; the posterior legs and the 

 apex of the femora, the tibiae and tarsi bright ferruginous ; the 

 clypeus has a white spot, its margin as well as the mandibles at 

 their apex ferruginous. Abdomen elongate-ovate. 



This species closely resembles H. coriaceus, but the colour of 

 the wings is diff'erent, and the second and third submarginal cells 

 are of about equal width, the second not being narrowed towards 

 the marginal as in that species.
