bright fulvous pubescence, the claws ferruginous. Abdomen smooth 

 and highly polished ; the base has a thin fulvous pubescence ; the 

 basal margins of the second, third, and fourth segments have a pale 

 fulvous fascia ; the first usually, and the second occasionally, inter- 

 rupted ; the apical segment clothed with similar pubescence. B.M. 



Male, Length 3|- lines. — Black, the face anteriorly clothed with 

 short white pubescence ; the clypeus white at the apex; the antennae 

 longer than the thorax, fulvous beneath, and more or less fuscous 

 above. Thorax finely and very closely punctured, the metathorax 

 rugose ; the tegulae rufo-piceous ; the wings hyaline, iridescent, 

 the nervures fuscous ; the tibiae at their base and apex, the anterior 

 pair in front, and the tarsi yellow ; the anterior tibiae are sometimes 

 fulvous in front ; the claws ferruginous. Abdomen elongate, very 

 smooth and shining, impunctate ; the margins of the intermediate 

 segments depressed, and having at their base laterally a little white 

 pubescence. B.M. 



This is a scarce species, its known localities being Greenwich and 

 Charlton (Kent), Yentnor (Isle of "Wight), and Bristol ; it has been 

 received from Scotland. Halictus fulvicomis has been taken with 

 it, and from that circumstance is believed to be its male ; further 

 evidence being desirable, that name is not adopted for the species.
