4. ASTATA ARGENTEOFACIALIS, Sp. nov. 



Nigra, argenteo hirstita, subtilis^ne punctata ; meianato 

 rugoso ; abdomine fusco \ alls hyalinis. ?. Long. 8 mm. 



Antennae covered with a white microscopic pile ; the 

 third joint perceptibly longer than the fourth. Head 

 opaque, coarsely alutaceous ; the occiput, lower part of 

 front, face, and clypeus densely covered with a silvery 

 pubescence ; clypeus incurved in the middle at the apex ; 

 mandibles piceous-red, black in the middle. Thorax 

 opaque, coarsely aciculated ; the metanotum finely rugose, 

 furrowed down the centre, near to the apex above ; the apex 

 oblique, coarsely rugose ; the pleurae, the pronotum (except 

 in the centre), the sides of the mesonotum ; the hollow at the 

 side of the scutellum, and the sides of the metanotum densely 

 covered with silvery pubescence. Abdomen shining, very 

 finely aciculate ; the segments lined at their junction with a 

 silvery pile ; the basal and apical segments are more or less 

 blackish. Legs covered with a silvery pile ; the spurs and 

 spines white. The second cubital cellule at the top is half the 

 length of the third, and half the length of the space bounded 

 by the recurrent nervures ; at the bottom it is not much 

 shorter than the third ; the first and second transverse 

 cubital nervures are straight ; the first recurrent nervure 

 is received not far from the base of the cellule, the second 

 at nearly double the distance from the apex. 



What is apparently the same species has the first and 

 second abdomial segments clear red, and the others quite 

 black.
