 Prosternum with three pale spines at each side. Wings smoky-hyaline ; 

 the fore edge, the transverse vein, and a dot on the subapical, clouded 

 with brown. Halteres yellowish. Abdomen with the margins of the 

 segments somewhat ciliated, more so in the male ; appendages of the 

 hypopygium nearly of equal length, dusky, the outer pair oblong, the 

 next bifid. Legs blackish ; the trochanters and the tip of the femora 

 pale yellowish ; the tibia, at the base a little, and at the tip more largely, 

 ferruginous ; in the female the base of the tarsi is also ferruginous, and 

 the femora and tibias sometimes almost entirely so ; the posterior coxas 

 have a spine outside, the hind femora one in front beyond the middle ; 

 all the tibiaa are armed with strong spines, the hind pair most thickly. 

 In the male the anterior tarsi and the hind metatarsus are pale yellowish, 

 the joints tipped with black ; the fore pair fringed outside with black 

 bristles, increasing in length towards the end, but ceasing at the tip 

 of the fourth joint, which has a long spine beneath ; the last three 

 joints of the intermediate tarsi are short, compressed, and ciliated at 

 both sides ; the fore tibia is armed at the tip inside with a black spur, 

 composed of three long spines united.
