266 HEBRINA. 



posteriorly not perceptibly separated from the membrane ; Mem- 

 brane very broad, thin, without perceptible nerves. Wings with 1 

 triangular, basal cell, and 1 nerve at its end. Sternum flat, with a 

 wide rostral channel. Legs proportionally long and stout ; posterior 

 thighs curved; coxce on each segment of the sternum very wide 

 apart, widest on the 3rd ; tarsi trimerous ; 1st joint very small ; 2nd 

 longer, stout, the end oblique, ^clasping the 3rd, which is long, 

 stout, thickest at the end, rugose and hairy, with 2 very short, 

 curved claws ; the 2nd and 3rd joints are so closely united as to 

 appear to form but 1 long, ovate joint. 



Abdomen beneath convex, but flattened in the middle ; apex 

 rounded; Connexivum narrow. Genital segments not visible from 

 above, beneath projecting through a circular opening in the last 

 abdominal segment ; in the $ , 2 ; the first short, annular ; the 2nd 

 at the base cylindrical, but then rapidly narrowed to a point, which 

 is curved upwards ; in the $ , 3 ; the 1st small, the 2nd and 3rd 

 cleft longitudinally in the middle, but not parted. 



This genus has several apparent relationships, and has been 

 variously placed by authors ; but on the whole, it appears to have 

 the nearest affinity to the sections between which we, following 

 Flor, have placed it.
