HYMENOPTERA. 163 



long ochraceous hairs, on the vertex the pubescence is fuscous ; 

 mandibles ferruginous at their apex. Thorax above clothed 

 with obscure yellow pubescence, at the sides of the meta- 

 thorax it is paler, and beneath cinereous ; the legs ferruginous, 

 their pubescence cinereous, that on the tarsi beneath is fulvous; 

 wings subhyaline, faintly clouded at the apical margins. The 

 basal segment of the abdomen rufo-testaceous, the apical margins 

 of the other segments also rufo-testaceous, each one much more 

 narrowly so towards the apex; the pollen-brush is very pale 

 fulvous. 

 Hab. Cape of Good Hope. (Coll. F. Smith.) 



60. Megachile frontalis, n. s. 



Male. Length 3^ lines. — Black, the face densely clothed with 

 silvery-white hair, on the vertex and disk of the thorax it is pale 

 ochraceous, short and very s])aring ; on the sides of the thorax 

 beneath, and on the legs and head beneath, it is white ; wings 

 hyaline, tegidse and nervures rufo-testaceous ; the extreme apex 

 of the tibiae and apical joints of the tarsi rufo-testaceous ; the 

 anterior tarsi simple, the coxae unarmed. Abdomen short, ob- 

 tuse at the apex, the apical segment vertical, concave, and co- 

 vered with short white pubescence, its margin notched in the 

 middle, on each side of which are foiu- short teeth, the innermost 

 being longest ; the segments are depressed at their base and 

 have white bands on their apical margins ; beneath, the segments 

 are similarly banded.

61. Megachile eurimera, n. s. 



Female. Length !)h lines. — Black, the face densely covered 

 vnth pale shining hair, having a golden lustre in certain lights ; 

 the mandibles broad, stout and tridentate at their apex, roughly 

 sculptured and ferruginous in the middle ; the pubescence on 

 the (hsk of the thorax is somewhat ochraceous, and cinereous at 

 the sides ; the legs rufo-piceous, the tarsi testaceous, the basal 

 joint of the posterior pair flattened and broadly dilated, the pu- 

 bescence on the legs is pale fulvous, and bright deep fulvous on 

 the tarsi beneath ; wings subhyaline, faintly clouded at their 

 apex. Abdomen subconical, clothed with fulvous pubescence ; 

 the pollen-brush of a golden yellow, palest towards the base of 

 the abdomen. 



Obs. This species closely resembles M. dorsata, but in that 

 insect the basal joint of the posterior tarsi is simple.
