Satybus p. God'. 



Body slender ; wings large, not thickly clothed with scales, transversely striated ; palpi densely pilose in front. 

 Head rather small, very hairy, but not tufted in front. 



Eyes prominent, very hairy. 



Antennce short, not half tlie length of the fore wings, cylindrical ; the joints being scarcely distinct above, annulated 

 with white beneath ; terminated by a slender, rather short club, composed of about twelve of the terminal joints, 

 which are more distinct than those at the base. 



Labial Palpi porrected obliquely ; the tip elevated above the level of the eyes, and advanced in front nearly as far 

 as the length of the liead ; the middle joint thickly clotlied with long hairs, set on at right angles, without any 

 tuft on the back of the joint ; the terminal joint small, elongate, pointed at the tip, and porrected in the same 

 line as the second joint. 

 ThoEjVX small, densely hairy. 



Fore Wings large, subtriangular, much less thickly clothed witli scales than ordinary. Costal margin not strongly 

 arched ; apical angle rounded. Apical margin straight, or but slightly convex ; hinder angle obtuse. Inner 

 margin straight, about equal in length to the apical. Costal vein very much swollen at the base, reaching the 

 costa at about half the length of the wing. Postcostal vein with its first two branches arising before the 

 anterior extremity of the discoidal cell (the second sometimes, however, being very close to it) ; the third 

 branch arising at about one third, and the fourth at about two thirds, of the distance between the end of the 

 cell and the tip of the wing ; the terminal part of the vein not extending to the outermost part of the convex 

 apex to which the upper discoidal vein extends. Upper disco-cellular very short, transverse : middle 

 disco-cellular much longer, rather curved, especially nearer its base : lower disco-cellular rather longer, nearly 

 straight, and continuous with the extremity of the middle one ; closing the discoidal cell transversely 

 considerably beyond the middle of the wing ; uniting with the third branch of the median vein at some 

 distance from its base, the latter branch being angulated at the place of junction. Median vein with its base 

 swollen nearly as much as the base of the costal vein ; its first brancli arising nearer the base of the wing than 

 ordinary, so that the space between the origin of the first and second branches is elongated, and nearly equal 

 to the space between the base and the first branch. Submedian vein sinuated, and very slightly thickened at 

 the base. • 



Hind l]iiy/s moderate-sized, triangularly subovate. Costal margin considerably angulated near the base, 

 subemarginate before the angle, beyond which it is nearly straight ; outer angle rounded. Outer margin 

 slightly scalloped, neither angulated nor tailed. Precostal vein very short, bent outwardly. Costal vein not 

 extending beyond the middle of the costa. Postcostal vein arising beyond the origin of the precostal, branching 

 , at a moderate distance from the base. Upper disco-cellular arising .a little beyond the base of the branch, 



oblique, slightly curved : lower disco-cellular rather longer than the upper, also oblique, and slightly arched ; 

 uniting with the third branch of the median vein at a little distance beyond its origin ; closing the discoidal 

 cell in rather an acute point at some distance beyond the middle of the wing. 



Fore Legs of the male very minute, thickly clothed with long hairs, forming a dense brush. Tarsus much shorter 

 than the tibia. Fo)-e Legs of the female slender, much longer than those of the male, scaly. Tarsus nearly 

 equal to the tibia in length, rather compi-essed and dilated at the tip, where it is furnished with several rather 

 strong divaricating spines, indicating the terminal articulations. 



Four Hind Legs short, slender, scaly. Tibia and tarsus armed beneath with several rows of short spines and 

 setae. Tibial spurs of moderate size. Ungues small, slender, acute ; extending but a very short distance 

 beyond the apical set£e and scales of the tarsus, oeneath which they are concealed. 

 Abdomen small and slender.
