Danepteeyx. New genus. 



Body robust, as in Issus and Tylana, but with narrow, strap- 

 shaped wing-covers and contracted angulate head, which give 

 the insect the appearance of the Orthopterous genus Tettix. 

 Vertex oblong quadrangular, with the anterior angles acutely 

 prominent, and the front margin between them almost angulate ; 

 the middle line broadly sunken, lateral margins carinately ele- 

 vated; front oblong, with the sides and middle line promi- 

 nently carinate, emarginate above and below ; clypeus convex, 

 conical, carinate on the middle line, the labrum completing the 

 cone, and stiffened each side by a thick carinate rib extending 

 along from the cheek ; rostrum long, and at base nearly equal 

 to the labrum in thickness ; antennae globose at base, placed as 

 usual below the eye, and carrying a very slender seta ; eyes 

 subglobular, emarginate beneath. Pronotum transverse, short, 

 depressed on the disk, the anterior angle subacute, with the 

 sides narrow, curved downward, with a tabulated space behind 

 the eyes, and the upper surface crossed by five slender, longitu- 

 dinal lines. Legs normal, the femora moderately compressed ; 

 posterior tibiae prismatic, carrying a series of four or five teeth 

 besides the chaplet of spines at tip. Wing-covers thick, opaque, 

 subligulate, but triangularly widened at base, and tapering at 

 tip where they become acutely rounded; the elements of vena- 

 tion are arranged in continuous longitudinal series, excepting 

 two short series of cells which run from the base along and par- 

 allel with the clavus; the areoles are all small, numerous, 

 mostly quadrangular on the outer half of the length of the wing- 

 cover, while those of the inner half are irregular, because of the 

 ramose irregularities of the longitudinal veinlets ; the costal 

 border crossed by numerous veinlets. Wings rudimentary. 

 Scutellum triangular, carinate, acute at tip. Abdomen obese, 

 carinated above. 



D. manca. New species. 



Grayish fuscous, pubescent, tinged with white, pale yellowish 

 brown when immature. Upper surface and wing-covers scab- 

 rous. Head rough, a little hairy, the carinate lines blackish, 

 interrupted with white ; lower part of cheeks and epistoma
