clypeus not transverse in the middle and its sides roundly waved ; 

 the hair is denser and longer both on the body and legs ; and on the 

 under side of the tarsi it is bright red. 



Megachile temora, sp. nov. 



Black ; the hair on the head and thorax white, on the apices of 

 the abdominal segments of a clearer white ; the abdominal scopa 

 bright red ; the hair on the tarsi and apex of tibiae red, on the rest of 

 the legs white. Wings hyaline, slightly violaceous at the apex, the 

 stigma and nervures black. ? . 



Length 11 mm. 



Cape Colony. 



Mandibles with three apical teeth ; the apical sharper and longer 

 than the others ; behind the third is a short, less distinct one ; the 

 punctuation is strong and close ; the hair sparse and pale red. Face 

 and clypeus closely and strongly punctured ; the apex of the latter 

 transverse, but with an irregular edge ; the face more closely, and 

 the front and vertex still more closely punctured. Thorax closely 

 punctured, the punctures forming almost reticulations in places ; 

 a smooth, narrow furrow down the centre of the mesonotum ; the 

 hair on the pleurae and metanotum long and dense. Metanotal area 

 coarsely alutaceous ; the rest finely closely reticulated. Apex of 

 hind tibiae smooth, depressed, with a raised broad keel in the centre; 

 metatarsus slightly narrower than the apex of tibiae, four times 

 longer than it is broad ; its outer side at the base with a rounded 

 depression or incision ; calcaria longish, curved, testaceous. The 

 hair on the under side of the tarsi is long, thick, and bright red. 



This species is not unlike M. imitata, Sm., as named for me by 

 the late Mr. Frederick Smith ; that has the mandibular teeth broader, 

 especially the apical one at the apex ; the punctuation is coarser, 

 and the face is smooth in the centre ; the pubescence on the meso- 

 notum has a fulvous tinge, and it wants the central impressed line; 

 the basal half of the scopa is white, the pile on the under side of the 

 tarsi is not bright red, and the apex of the clypeus is straight, not 

 with an irregular edge. In M. imitata the apical mandibular tooth 

 is large, broad, bluntly rounded at the apex ; the second is small, 

 more oblique, and bluntly rounded ; it is followed by two broad, 



rounded projections.
