ine M. ccerulea the insect described by Lepeletier, who particularly 

 calls attention to the peculiarity in the venation. The Xylocopa 

 ccerulea of Bingham," is M. ahhotti, as his figure very clearly shows. 



Fabricius described his Boinbus ccuriileus from New Caledonia, and 

 Bingham says that it ranges to New Caledonia. Vachal has recently 

 reported on a collection of bees from New Caledonia, and includes 

 neither M. coirulea nor any relative of it. I think there can be no 

 doubt that " New Caledonia " was an error, the real range of the 

 insect being from Java to Siam. Another blue-haired species, 

 Xylocopa g^'uhaueri Friese, has been described Upper Perak, 

 Malacca. It is very distinct from those now under discussion. 



The male of 31. cm'vlea was briefly indicated by Ashmead from the 

 Javan specimens under his generic description of Cyaneod'eres. It is 

 large, black, with the hair of the head and thorax (so far as can be 

 seen from the specimens, which have been in spirit) greenish or 

 olivaceous brown, not at all blue. The eyes are very large, and 

 approach above, leaving only a narrow space between them and the 

 large ocelli. The face is without light markings; the copper-red 

 hairs on the labrum are very brilliant. The wings are a little lighter 

 than in the female. The abdominal segments are red at the extreme 

 base, as becomes conspicuous when they are unusually extended. The 

 hind tibia' have at the apex within a large obtuse shining tubercle, the 

 end of which is directed posteriorly. The flagellum beyond the base 

 is ferruginous beneath.

Genus PERDITOMORPHA Ashmead. 

 Perditomorpha Ashmead, Trans. Amer. Eiit. Soc, XXVI, 1899, p. 86. 



This is a genus of Panurgines close to Camptopceum, from which 

 it is distinguished by the absence of light markings on the face, the 

 simple spur of middle tibia, the very narrowly subtruncate marginal 

 cell, and the transversomedial nervure meeting the basal. These 

 remarks all apply to the female, the male of Perditomorpha being 

 unknown. In the type of Camptopceum {C. frontale Fabricius from 

 Europe) the basal nervure falls far short of the transversomedial, 

 and the second submarginal cell is longer than the first. In the South 

 American C. ochracevm Friese, C. suhmetallicum Spinola, and C. 

 flaviventre Friese, which are before me, the basal nervure also falls 

 far short of the transversomedial, and the apex of the marginal cell 

 is much more remote from the costa than it is in Perditomorpha. The 

 spur of the middle tibia is finely denticulate in all these species, as 

 also in Parafriesea^ prinii {P. hrasiliensis Schrottky, Camptopceum 

 prinii Holmberg) . 



« Fauna of British India, Hymenoptera, I, p. 544, pi. iv, fig. 8. 

 & Friese refers this genus to Perdita. It is very distinct from Pcrdita, but 

 scarcely separable from CalUopsis.
