 but encroaching very little beyond the 

 latter; a round brown spot on the anterior crossvein, and a so-

 Hab. Hatam, N. Guinea, .lune 1875 (Beccari) ; three females. 

 NB. This species differs in its characters from the typical 

 Slenopterinae. As in S. cfjues, the third and fourth veins are con- 

 verging ; the transverse thoracic depression is arcuate and unin- 

 terrupted, but the second vein ends in the costa at a rounded, 

 instead of an acute angle ; the anterior crossvein is not oblique; 

 the posterior one is slightly sinuate ; the thorax is less bulky 

 and its vertical diameter shorter ; the front coxae are shorter.
