SYMMACHIA. 



445 



Eyes moderate-sized, naked. 



Antenna' very slender, about three fifths of tlic length of the fore wings ; articulations indistinct, not ringed witli 

 white ; terminated by a rather short and moderately robust club, gradually formed, obtuse at the tip. 



Labial Palpi very small, compressed, directed obliquely upwards, but not reaching higher than one fourth of 

 the length of the eye, and not extending so far as the hairs of the face, clothed beneath with short scaly hairs ; 

 apex subacute. 

 Thorax rather robust, clothed with scaly hairs. 



Fore Wings large, subtriangular. Costal margin very convex at tlie base, deeply emarginate in the middle ; 

 apex rounded. Apical margin but slightly convex in the males, more dilated in the females. Postcostul vein 

 emitting the first and second branches before the anterior extremity of the discoidal cell, and the third branch 

 half way between the cell and the apex. Upper disco-cellular vein arising at a moderate distance beyond the 

 second branch of the postcostal, and forming, as it were, the base of the upper discoidal vein : middle disco- 

 cellular arising at a short distance from its origin, very slender, transverse, slightly curved at its lower end : 

 lower disco-cellular about the same length as the middle one, equally slender, but straight and transverse, 

 uniting with the third branch of the median vein at a moderate distance from its ori";in. 



Hind Wings subtriangular, each angle occasionally produced into an obtuse point; base of the costa strongly 

 angulated. Costal vein extending about three fourths of the length of the costa. Precostal vein oblique, 

 nearly reaching to the costa, and acuminated at the tip. Postcostal vein arising much nearer the body 

 than the precostal, bi'anching at a moderate distance from the base. Upper disco-cellular very slender, oblique, 

 arising at a very short distance from the base of the branch of the postcostal : lower disco-cellular also very 

 slender, rather longer than the upper one, but transverse, uniting with the third branch of the median vein at 

 a short distance from its origin. 

 Fore Legs of the male very slender, longer in proportion to the size of the insects than ordinary, loosely clothed 

 with long slender hairs. Tarsus and tibia of equal length. Femur short. Fore Legs of the female slender, 

 scarcely longer than those of the male, scaly. Fenuir and tarsus of equal length, each longer than the tibia. 

 Tarsal joints not spined beneath. 

 Four Hind Legs of the ordinary proportions, slender, scaly. Tarsal joints armed beneath with numerous short 

 spines. 

 Abdomen moderately elongate in the males ; ovate in the females. 



The insects of this genus are amongst the prettiest of the present family, from almost all the species of which they are distinguished 

 by the peculiar shape of the fore wings, wliich do not differ, as to the form of the costa, in the opposite sexes. Q'he females, 

 however, as usual, liave the apical margin more convex, especially towards the hinJer angle, than in the males. S. Colubris is 

 remarkable for having the wings powdered with ghttcring green and silvery atoms on tlie u|)|ier surface, wliilst the males of S. 

 Probetrix and S. Accusatrix have the hind wings marked with a wide baud of orange red along the costal margin.
