This species is confined to Borneo. Sandakan (Pryer— 
eoll. Distant); Kuching (Sar. Mus.); Western Borneo 
(Brit. Mus.). 
I have identified a single male in the Sarawak Museum, 
which was taken near Kuching in April, as this species ; 
but the very slight difference in the shape of the opercula 
seems hardly sufficient to give it specific distinction from 
D. rufivena. From the figures of these two species in 
Mr. Distant’s Monograph of the Oriental Cicadidae (PI. 
vi., fig. 6, a, b, and Pl. xii., fig. 9, a, 6), the only noticeable 
difference seems to be that the opercula of the male D. 
mellea are slightly more evenly rounded at their base than 
in D. rufivena, where the outer and lower angle is more 
produced and more pointed. In regard to thecolour, Mr. 
Distant himself admitted in his Monograph to having seen 
forms of so intermediate a character that he recognized 
the possibility of its being a subspecies or simple variety 
of D. rufivena.
