The thorax is as in the type with the exception of a small dark spot on the pos- 
terior lateral portions of the praescutum. The wing-pattern is shown (Fig. 10, 
10). The male hypopygium is very similar in structure to 7’. nodipes Speiser, 
but the coloration of the body and wings is very different.
