To this species I coimt three females collected at Itoki 

 and Kitta ( /i, 9 / 2 ; 20 / 5 1891). 



The shape and structure of the clypeus is very agreeing 

 with the description and the figure published by Mr. Saussure 

 in his Revision du genre Synagris. The maxillary palpi are 

 4-jointed. The species belongs thence to the subgenus Para- 

 gris. The body is for the most part black and clothed by a 

 very short pubescence. The four last abdominal segments 

 are yellowish red. The clypeus and the mandibulse are dark 

 red-brown. The mandibulee are slightly curved with three 

 deep emarginations at the thin margin. The longest interval 

 between the eyes on the vertex as long as the joints 1 — 3 of 

 the flagellum. The interval between the posterior ocelli a 

 little shorter than the distance from the eyes. The wings are 

 dark fuseous with violet effulgence. The distance between 

 the end of the radial nervure and the inserting-point of the 

 third transverse cubital nervure longer than the distance from 

 that point to that of the second transverse cubital one. 



Length 24 mm. 



Exp. 45 mm.
