ing of the Almighty, — the manifestation of His eternal Wisdom, in- 

 finitely diversified, sustaining, directing, impelling all things, and 

 making all things work together for the good of the whole. 



Genus. — Osmia, Panzer, Latreille. 

 Anthophora, Fabr. Trachusa, Jurine. Apis, Linn., Kirby. 



Sp. 1. Osmia leucomelana. 

 Apis leucomelana, Kirby 's Mon. 



Female. — Length 3£ — 5 lines. Black, shining and minutely punc- 

 tured. Head as wide as the thorax, a few white hairs on the face, 

 along the margin of the eyes. Antennae black, piceous beneath to- 

 wards the apex. Maxillae tridentate. Thorax ; a thin griseous pu- 

 bescence on the metathorax, and also beneath. The legs black: the 

 tarsi beneath, and the claws, rufous. Abdomen ; the first three seg- 

 ments laterally, and the fourth entirely, margined with white hairs, 

 clothed beneath with cinereous hairs. 



Male. — Length 3 — 4 lines. Brown black, closely punctured. 

 Head : face clothed with bright yellow hairs. Antennae black, pice- 

 ous beneath. Thorax thinly clothed with palish yellow hair, more 

 thinly so with darker hairs on the disk. Legs black ; the tarsi rufous 

 beneath, the apical joints of the anterior and intermediate tarsi, and 

 all the claws, rufous. Abdomen ; the first segments laterally, the se- 

 cond, third and fourth, entirely, narrowly margined with white hairs, 

 all frequently more or less interrupted ; the sixth segment produced 

 laterally, forming an obtuse tooth, the seventh is deeply fossulated 

 and dentate at the apex ; beneath, the second segment is produced 

 into a large obtuse projection, the third and fourth deeply emar- 

 ginate and fringed with yellow hairs. 



I am not aware that the male of this species has been previously 

 described. It is a remarkable insect in its abdominal appendages ; 

 the nearly half-circular projection on the second segment beneath, to- 

 gether with the cavity on the seventh, above, distinguish it from the 

 other males of the genus. The species is very local. I have met 

 a single specimen at Charlton in Kent ; at Hawley in Hampshire not 

 uncommon in July, but it is more abundant still in the neighbourhood 

 of Bristol. 



Sp. 2. Osmia spinulosa. 

 Apis spinulosa, Kirby 's Mon. 



Female. — Length 3 — 3| lines. Black, shining, rather coarsely
