Length 10-11 mm. 



Deesa. August. (Nurse.) 



Antennae as long as the body, the apical joints curved, clypeus longer than 

 wide, coarsely, closely punctured ; the labrum strongly, but not so closely 

 punctured ; the apex of the clypeus is transverse, with the sides rounded. 

 Mesonotura punctured, but not so closely nor so strongly as the clypeus. The 

 basal 2 abscissa? of the radius are of equal length ; the 3rd is fully one-fourth 

 longer ; the 1st recurrent nervure is interstitial, the 2nd nearly so. 



This does not appear to me to be duvancelii, Lep. ; according to Bingham, 

 that has the clypeus " square, very slightly emarginate anteriorly and very 

 lightly punc:ured," in my species it is transverse and quite strongly punctured; 

 the " Gth and apical segments with fuscous pubescence ;" here black ; the cly- 

 peus in (jlabricoriiis is not " nearly square," but distinctly longer than wide ; 

 according to Bingham, too, the thorax is more strongly punctured than the 

 head, the reverse being the case here. 



Megachile gathela, sp. nov. 



Black, the head and thorax densely covered with white pubescence ; the 

 abdomen with 5 distinct white hair bands, the scopa white, wings hyaline, the 

 stigma fuscous, the nervures blacker, the basal 2 abscissae of the radius equal 

 in length ; both the recurrent nervures are received close to the transverse 

 cubitals. Mandibles bidentate, both the teeth broad, the 2nd smaller than the 

 1st ; the basal half of mandibles densely covered with white pubescence. 

 Pubescence on legs white, that on the underside of hind metatarsus tinged 

 with rufous. Apex of hind tibiae one-fourth thicker than the base of meta- 

 tarsus. $ . 



Length 7 mm. 



Deesa. January and February. 



Head wider than the thorax, the temples short. Clypeus with the sides 

 strongly punctured, the centre almost smooth. Metanotal area strongly aci- 

 culated, the rest punctured, but not strongly. Back of abdomen closely 

 punctured, the pygidium more closely than the rest. The fore coxae in the £ 

 are armed with a longish stout tooth, which is clearly longer than it is 

 wide at the base. The apex of the abdomen, in the £, is armed with - 6 irre- 

 gular, not very strong pale and black teeth, the central 2 being widely separated ; 

 the part behind them is depressed. The temples are wider than they are in 

 the 9. 



Megachile uombayensis, sp. nov. 



Black, the hair on the head and thorax white, the dorsal abdominal segments 

 narrowly banded with white pubescence, the scopa on apical half red, on basal 

 white •. wings clear hyaline ; the legs for the greater part fuscous ; the mandibles 

 bluntly bidentate at the apex, the base broadly dilated in the middle ; base of 

 hind metatarsus two-thirds of the width of the apex of tibiae, 9* 



Length 8 mm. ; breadth 3 mm.
