This genus contains but three species so far, two occurring in 
the Sudan and the other from the Philippine Islands. In the 
males described here as Q. dubia there is a small area of flat 
white scales in the mid line of the thorax in front. No such 
scales occurred in the $’s of Q. unilineata (Theobald), and hence 
they have been placed as a distinct species. It is quite possible 
however that difference is purely a sexual one, and that Q. dubia 
is only the $ of Q. unilineata. I have not seen Miss Ludlow’s 
species. The three species can be told as follows :— 
Tborax brownish black, a median white line, 
divided by very narrow dark line, 2 small white 
spots where it ends, a white patch in front of 
roots of wings, a few white scales before white 
scntellum . unilineata. Theobald. 
Thorax black with a median patch of flat silvery 
scales in front by head, a large white patch on 
each side and a smaller one near wings, and a 
patch of flat white scales on each side before 
scntellum ... dubia. n. sp. 
Thorax brown with dark brown median area, white 
scales near head, a broad white lateral stripe 
about \ length mesonotum, large white spot in 
front of base of wings, a short median white to 
yellow line behind, and a short one on each 
side in front of scutellum. Legs basal white 
spots, not bands..... gardnerii. Ludlow.
