Some Neiv Genera and Species of Hymenoptera. 239 



closely punctured, the scutellum less and the pleurae more strongly 

 than the mesonotum. Metanotum opaque, alutaceous, the bajse 

 finely, irregularly, indistinctly striated. There is a short furrow on 

 either side of the mesonotum near the base. Second cubital cellule 

 distinctly narrowed in front ; the first recurrent nervure received 

 near the apex ; the second shortly beyond the middle of the cellule. 

 The second abdominal segment is distinctly, the third less distinctly 

 depressed at the base. The eyes are long, converge below and 

 clearly incised on the inner side. 



Halictus dispositus, sp. nov. 



Black, shining, the hair bright white ; flagellum testaceous below 

 towards the apex ; wings clear hyaline, highly iridescent, the stigma 

 dark testaceous, the nervures black. ? . 



Length 5 mm. 



Cape Colony. Pearston. 



Metanotal area closely, distinctly reticulated, the sides more 

 irregularly obliquely striated. Clypeus strongly, deeply, irregularly, 

 but not closely punctured. Face with shallow, scattered punctures ; 

 the front and vertex closely minutely punctured ; on the upper half 

 of the front is a shining, impressed line, on the lower a fine keel 

 which extends to between the antennae. Pleurae opaque, coarsely 

 granular ; a deep, oblique furrow below the tubercles. Abdo- 

 men shining, impunctate, the apices of the segments pale testaceous ; 

 the anal rima blackish, the sides except at the apex distinctly 

 margined, the apex depressed, rounded behind, dark testaceous. 

 Labrum covered with stiff black hairs, which give it a striated look. 

 The third transverse cubital nervure is broadly rounded ; the first 

 recurrent nervure is almost interstitial, being received in the extreme 

 apex of the cellule. 



Halictus ^thiopicus, sp. nov. 



Black ; the abdominal segments broadly banded with rufo- 

 testaceous ; legs bright rufo-testaceous, their tibiae streaked with 

 yellow ; the coxae, trochanters and base of anterior femora black ; 

 mandibles piceous, black at the base ; antennae black, the flagellum 

 testaceous below ; wings clear hyaline, highly iridescent, the stigma 

 and nervures pale testaceous, the costa darker; the apical nervures 

 beyond the third transverse cubital nervures almost obsolete. ? .
