oe form, ? sp. nov. (1) Antennae wholly black: (2) 
wings quite clear, except for a little yellowish in 
the subcostal cell: (3) black hair on anterior margin 
of thorax : (4) scutellum very dark, reddish brown, 
nearly black: (5) sides of abdomen so closely 
covered with dense white scales that its ground 
colour is not properly visible, but I am under the 
impression that the sides are red, as in vitrea. 
Unfortunately only one specimen each of my new species and 
the uncertain form is available but what I take to be vwitrea, Big., 
is represented by several, including a pair taken im cop. ‘The third 
form has the appearance of having been wetted (at least its head 
and thorax) so that I view it with some suspicion, but the abdo- 
men appears in good condition. 
On the assumption of my correct identification of vitrea, Big., 
I have ventured to redescribe it.
