Hab. — Para. 



This unique example is from the private collection of 

 Mr. H. W. Bates. This insect very closely resembles 

 the female of X. micans ; it may possibly be a variety of 

 it, but it differs as follows from that species: — The deep 

 pit observable in micans on each side of the clypeus, not 

 npon it, is Avanting ; it has a snow-white tuft of hair on 

 the anterior margin of the clypeus ; the mesothorax is 

 glassy smooth, and has only a few minute mdely-scattered 

 punctures at the sides; the metathorax is destitute of 

 pubescence ; the abdomen is much more finely punctured, 

 and the insect is of a bright blue, not obscure violet ; the 

 wings are darker. 



*99. Xylocopa ornata. 



Female. — Head blue-black, with tints of violet on the 

 vertex and of green on the clypeus ; the sides of the face 

 with griseous pubescence. Thorax obscure nigro-ajneous 

 above, with violet tints on the disk, which is smooth and 

 shining ; on the scuteUum it is brassy ; beneath green and 

 with griseous pubescence ; the legs are nigro-piceous be- 

 neath, and tinted with green above; the pubescence on 

 the outside of the intermediate and posterior tibise is 

 fulvous, within it is black; the wings subhyaline, and 

 with a coppery iridescence; the nervures rufo-piceous. 

 Abdomen of a shining brass colour, brightest towards the 

 apex ; punctured, but the apical margins of the segments 

 are smooth and shining ; the abdomen is covered with 

 short fulvous pubescence, and, toAvards the apex, the sides 

 are fi-mged with the same. Length seven lines.
