covered with a dull golden down and with some long 

 black hairs ; its apex bearing much longer hairs. Mandibles 

 very large, opaque, the middle above with some elongated 

 punctures and elongated striae ; the apical tooth large ; 

 the basal rounded in the middle. Antennae black, 

 glabrous. Thorax opaque, closely rugosely punctured ; 

 above thickly covered with rufous hair, this being also 

 the case on the upper part of the pleurae ; the hairs on 

 the lower part are much darker ; on the sternum fulvous, 

 the latter broadly depressed in the middle at the base. 

 Wings smoky, darker and more violaceous at the apex ; 

 the base with a slight yellowish tinge ; the costa, stigma, 

 and nervures black ; the last with a yellowish tinge in the 

 middle of the wing ; the recurrent nervures are both 

 received at the same distance from the transverse cubitals. 

 Legs thickly covered with stiff black hairs ; the anterior 

 four tibiae end above in a large stout somewhat 

 triangular process, which ends in a small curved point. 

 The basal abdominal segment broadly depressed in the 

 middle above ; the sides, base, and apex thickly covered 

 with rufous hairs ; the second segment depressed at the 

 base, fringed with fulvous hairs, this being also the case 

 with the third at the sides ; the second and following 

 segments thickly covered with stiff black hairs. Ventral 

 surface thickly covered with long stiff black hairs. The 

 hinder calcaria are short and thick. 



This Megachile is, next to M. Pluto Sm. (from Bachian), 

 the largest of the species from the Oriental Region. 

 Smith's species is 18 lines in length, that being however 

 the length of a 2, the only sex known to its describer 

 (Trans. Linn. Soc, V ., 1860, 133). Our species is also 

 apparently related to M. monticola Sm., but I cannot make 

 it agree with Smith's description.
