Halictus schoenlandi Cam. 

 1905 Halictus schoenlandi Cameron, $, in: Rec. Albany Mus., Vol. I, p. 329. 



$. Black, the apical third of the ist abdominal segment, the whole of the 2nd and the greater part of 

 the 3rd red; wings clear hyaline, the stigma fuscous, the nervures pale. Hair dense whitish-cinereous. L. 5 mm. 



Metanotal area closely, longitudinally reticulated, more finely and closely at the apex than at the base, 

 the sides with stouter, more widely separated oblique Striae. The hair on the face, clypeus and front is very 

 dense, hiding the sculpture. Sides of mesonotum finely, closely and distinctly punctured, the centre more widely 

 and strongly punctured. Apex of scutellum closely, the base sparsely punctured. Calcaria pale testaceous"; the 

 hair on the innerside of the tarsi is rufous. The 3. abscissa of radius is not much longer than the 2.; the 3. 

 transverse cubital nervure is oblique in front, the hinder (and smaller) part is broadly rounded. Tegulae piceous. 

 Antennae stout, the joints of flagellum almost moniliform. The apex of the metanotum is transverse in the 

 middle above, its sides rounded. Only the base of the 2. abdominal segment is depressed. There are no basal 

 or apical fasciae on the abdominal segments. Above the propleura is dilated into a triangulär, large projection, 

 which is bare below, above thickly covered with long white hair; it is as long as its width at the base and 

 becomes gradually narrowed towards the apex.
