86 OMMATIUS SCHLEGELII. 



Wings rather narrow , hyaline with the tip cinereous ; 

 veins blackish; the space between the costal and subcostal 

 veins, in the distal half of the wing, is somewhat infus- 

 cated. The two longitudinal veins issuing from the discal 

 cell, together with the inferior branch of the external sub- 

 marginal cell, are strongly curved; middle crossvein in- 

 serted at about two-thirds of the discal cell , which is 

 rather elongate and narrow; fourth posterior cell closed and 

 appendiculated at its proximal as well as at its distal end. 



A single male specimen from the island Waigiou (Bern- 

 stein) in the Ley den Museum. 



By its tender structure, its narrow face and front, the 

 peculiar shape of its tarsi and the unusually waved 

 veins in the apex of the wings, this species differs so 

 much from the other species of Ommatius, that most pro- 

 bably future investigations will show the necessity for ma- 

 king a separate genus for its reception. 



I dedicate this very distinct species to the memory of 

 the late Professor H. Schlegel, the regretted Director of 

 the Leyden Museum.
