ments ; the margins of all the segments have a fascia of white hairs, 

 generally obsolete on the first, widely interrupted on the second, and 

 frequently more or less so on the third. The underside of the abdo- 

 men is densely clothed with black hair. 



Male. — Length 3f — 4j lines. Green, deeply and closely punc- 

 tured. The head as wide as the thorax : the face clothed with fulvous 

 hair. The thorax has a similar pubescence on the disk, inclining to 

 hoary beneath. The legs have also a thin fulvous pubescence. The 

 abdomen is gradually narrowed towards its base, the margins of the 

 first and second segments are depressed, and these, as well as the 

 third, are fringed with fulvous hairs, forming continuous fasciae on the 

 margins of the fourth and fifth, the sixth is emarginate, and the se- 

 venth segment is incurved and bidentate. 



This species appears to be very generally distributed. I have bred 

 it from decayed wood, and my descriptions are from such specimens. 

 The bright fulvous hair of the male soon fades from exposure. The 

 colour of the female varies from violet-blue to nearly black. 



Sp. 6. OSMIA TUNENSIS. 



Apis tunensis, Fab., Kirby. Apis aurulenta, Panzer. 



Female. — Length 4 — 4f lines. Black, deeply and closely punc- 

 tured. Head as wide as the thorax : the face with thinly scattered 

 fulvous hairs, extending to the vertex : the mandibles stout, promi- 

 nent and tridentate, the exterior tooth acute ; coated above with short 

 fulvous hair. The thorax clothed with bright fulvous hair. The legs 

 thinly coated with the same : the tarsi beneath clothed with ferrugi- 

 nous hair ; the calcaria testaceous ; the claws rufous. The abdomen 

 subglobose, laterally clothed with bright fulvous hair, all the margins 

 have a fascia of hair of the same colour, the underside densely clothed 

 with deep ferruginous hair. 



Male. — Length 4 — 5j lines. Black. The face clothed with bright 

 pale yellow hairs, those on the vertex ochraceous. The thorax also 

 clothed above with an ochraceous pubescence, and with hoary be- 

 neath. All the legs are fringed with a similar pubescence : the tarsi 

 beneath ferruginous ; the calcaria are testaceous and the claws rufous. 

 The abdomen gradually widens from its base ; the basal segment is 

 thinly clothed with ochraceous hairs ; the other segments laterally, 

 and the margins of the third, fourth and fifth, with a fascia of bright 

 ferruginous hair : the sixth segment is emarginate, and its extreme 

 lateral margins deeply notched, forming a somewhat acute tooth; the 

 seventh is incurved, and acutely bidentate.
