(EDIPODIN^. 115 



the intercalary vein distant from the median vein ; wings with 



dilute colouring, nebulous, the veins next the costal margin 



and frequently (in the male) the median vein also incrassate, 



the costa with a dusky stigma, the ulnar area dilated and 



with remotely scalariform venation. 



d. The intercalary vein of the tegmina running midway between 



the median and the ulnar veins, only apically a little 



approximating the former ; veins of the wings slightly or 



scarcely incrassate Chortophaga, Sauss. 



dd. The intercalary vein of the tegmina distinctly nearer the 

 ulnar than the median vein ; the veins of the wings referred 

 to (under cc) distinctly incrassate in the male. 

 e. Antennae very short, stout ; head compressed, the fastigium 



prominent, angulate Chimarocephala, Scudd. 



ee. Antennae rather long and slender, head subtumid, rotun- 



date, the fastigium in the female anteriorly obtuse . . Encoptolophus, Scudd. 

 bb. Interspace between the metasternal lobes rather broad, in the 

 male quadrate, in the female transverse. 

 c. Lateral canthi of the metazona traversing the principal sulcus 

 (where they are frequently cristulate or rugose), not inter- 

 sected by it (or only in individual cases) ; principal sulcus 

 more or less obsolete or shallow in the lateral lobes. 

 d. Median carina of the pronotum conspicuous, but not cristate. 

 Tegmina moderately densely reticulate, the apical third 

 at least remotely and quadrately reticulate. 

 e. Smaller forms. The pronotum not rugose. Wings sub- 

 vitreous, not definitely coloured. 

 /. Posterior lateral angles of the pronotum acute. The 

 carina? and sulcation of the vertex continuous with 



those of the frontal costa Hippopedon, Sauss. 



ff. Posterior lateral angles of the pronotum rounded. The 

 sulcation of the vertex not continuous with that of 



the frontal costa Camnulla, Scudd. 



ee. Larger forms. The pronotum rugose. Wings decidedly 



coloured Hippiscus, Sauss. 



dd. Median carina of the pronotum very slight. The whole 



of the tegmina rather densely reticulate and coriaceous, 



membranaceous or subvitreous at the extreme tip only. 



e. Less stout ; mesosternum only a little broader than the 



head ; tegmina extending well beyond the tip of the 



abdomen in both sexes, the intercalary vein distinct 



throughout and everywhere very much nearer the median 



than the ulnar vein ; transverse fascia of wings without 



a subcostal taenia ............. Leprus, Sauss.
