Ataxigamia, gen. nov. (Ataxia = coni\i^\o\\). 



Male winged, female (?). Head prominent. Pronotum ciliate 

 meso- and meta-notum, also underside of the thorax, coxte, and 

 femora more or less densely covered with long, silky hair. Pro- 

 notum rounded in front, slightly sinuate on each side of the 

 hood-like middle part, gradually narrowing rearward, produced 

 behind, apex broadly rounded ; sides much deflexed anteriorly, 

 margin slightly rough, disk with coarse, shallow impressions. 

 Elytra and wings large, perfectly folded ; elytra acuminate ; 

 wings with anal area fan-like. Legs and tarsi long and slender, 

 claws small, arolia minute. Abdomen very much depressed, 

 segments scarcely constricted, angles not produced, obtuse or 

 rounded. Supra-anal lamina subtrigonal, hindmargin rounded, 

 entire, nearly flat. Cerci very much longer than lamina, sub- 

 terete, 16-jointed, finely pilose, obtuse. Subgenital lamina ex- 

 ceeding the upper, broad, hindmargin emarginate. 



In the "Archiv fiir Naturgeschichte" Gerstacker also describes 

 a genus (Gijnojjeltis)., in which the fore femora alone are spined 

 (Zool. Rec, YI., 461, 1864).

The principal aberrant characters consist in the fore femora 

 alone bearing spines, the anal area of the elytra being narrow, 

 and longer than in any other species, the anal area of the wings 

 folding flaljellately, and the supra-anal lamina being entire, 

 rather long, and nearly flat.
