sexes, shaped as in S. alhipes, and also brown in color. The an- 

 tenna in the female is short, the basal joint globular and brown- 

 ish yellow, the succeeding joints dark brown, paler and swollen 

 at the base, with a whorl of long hairs to each and short hairs 

 scattered between. The male antenna is banded brown and yel- 

 low, with silky, pale brown plumes, with yellow reflections. 



The thorax is brown with yellow hairs scattered unevenly, and 

 Avith four dark brown, longitudinal, nude stripes, the two median 

 ones close together, extending from the anterior margin back- 

 ward beyond the middle, the lateral ones extending from tlie 

 posterior margin forward to the middle. The pleura are brown 

 with a few dirty white scales. The legs are brownish black ; the 

 femora yellow beneath and a broad yellow band at the apex, 

 with a black ring medially but nearer the apex; the tibiae with a

small yellow spot at the extreme apex and a broad yellow band 

 at the base, with a black median ring nearer the base. The first 

 joint of each tarsus is very short, the second very long, the suc- 

 ceeding ones normal; all except the apical one banded with yel- 

 low at the base, very broadly on the posterior tarsi. The claws 

 of the male anterior and mid tarsal joint are very large, equal in 

 size, and each with a long, slender, median tooth and a blunt 

 basal one, serrated on the inner margin of the basal half. The 

 posterior claws are precisely the same in size and shape, but 

 with an extra thin branch on the outer curve of each claw (fig. 

 113, i). The female claws (fig. 113, 2) are alike on all feet, 

 equal, slender, and with a basal tooth, serrated on the inner 

 margin of the basal half as in the male. The wings are grayish 

 hyaline, the veins clothed with black and yellow hair-like scales,
