30 BEES OF GREAT BRITAIN, 



the nervures ferruginous ; the pubescence on the tarsi and 

 posterior tibiae pale fulvous ; the apical joints of the tarsi ferru- 

 ginous. Abdomen oblong-ovate, shining, and very delicately 

 punctured ; on the apical margins of the segments laterally a 

 short hue of snow-\vhite pubescence, the first frequently ob- 

 literated. 



This very distinct and pretty little bee has oidy been twice 

 captured ; it occurred on Havvley Green, Hants : at first sight, it 

 has a very close resemblance to Osmia leucomelana : the male has 

 not been taken in England. St. Fargeau's insect is probably 

 not identical with this, as he does not mention the remarkable 

 subquadrate head; the male has the flagellum fulvous beneath, 

 the margin of the clypeous yellow^, and all the tarsi and tibige 

 testaceous, the latter fuscous at their base; the fifth and sixth 

 segments of the abdomen having similar spots to the female.
