Differs from genuine X, varians, Sm. (S. Brazil), by being 

 less stout, with a narrower abdomen ; tegulte black (red in 

 varians) ; abdomen yellower and with more pale hair. The 

 oblique spine on outer side of hind tibia is practically as in 

 varians. Wings orange-tinted as in varians. 



Differs from A', ornata, Sm. (S. Paulo), by being larger, 

 with the abdomen very much darker and less golden, and the 

 face much narrower. 



Differs from X. viridis, Sm., by the dark hair of thorax, 

 and the abdomen without bands. Easily known from 

 X. harhata, Fabr., by the colour, and the absence of the 

 shining silver-white hair which covers the cheeks of harhata. 

 Distinguisiied from X. electa, Sm., b}' the light hair on legs, 

 colour of abdomen, &c.

Xylocopa lunulata minensiSj subsp. n. 



^ . Agrees exactly with Lepeletier^s description of his 

 A", lunulata from China, except that the clypeus (except its 

 broad lower border) is dull white. Length a little over 

 30 mm. ; anterior wing 2.5| ; face broad, the inner orbits 

 parallel ; face-niarkiugs greyish-ivory colour, including in 

 addition to the clypeus a semicircular supraclypeal mark, a 

 lunule on each side of anterior ocellus, and broad lateral 

 marks. The face is thinly clothed with black hairs. The 

 general appearance of the insect is like that o£ X. dtssimilis, 

 Lep., which also occurs iu China, and in view of what Perez 

 has written concerning the variability of dissimilis it is quite 

 possible that lunulata and minensis are both local races of 

 that insect.
