THE NATIONAL MUSEUM, MELBOURNE. 
By Howard Ashton. 
(Plate IV., Figs. a, ¢, i.) 
While engaged in the preparation of the Catalogue of Victorian 
Cicadide in the National Museum, the following species were found 
to be new. 
These, with the consent of the Director, Professor Baldwin 
Spencer, [ am now enabled to describe and figure. 
Family Cicadide. 
SUB-FAMILY GICADINA. 
Division Cicadaria. 
GENUS MACROTRISTRIA. 
MACROTRISTRIA DORSALIS, SP. Nov. (Fig. a, 1, 2.) 
Male.—Body above ochraceous, mesonotum tinged with 
brownish, in fresh specimens probably greenish. Central suleus 
to vertex of head, a short longitudinal and anteriorly angulate spot 
on each side of region of ocelli, and anterior margins to eyes 
and basal margin of front very narrowly black. Abdomen with a 
broad central dorsal longitudinal fascia extending from base, where 
it is very wide, and narrowing sharply to penultimate segment ; 
base of apical segment and spot on anal appendage piceous or black. 
Face and head beneath, bright ochraceous ; sternum, opercula, and 
legs sordid ochraceous brown; anterior and intermediate tarsi and 
disc of abdomen beneath warm fuscous. Tegmina and wings hyaline, 
tale-like ; tegmina with costal membrane and area and basal half of 
venation ochraceous ; postcostal area and apical venation fuscous, 
and claval nervure black ; wings to basal two-thirds of venation pale 
ochraceous, apical veins light fuscous. Head (including eyes) equal 
in breadth to lateral dilations of posterior pronotal margin. 
Abdomen much shorter than space between apex of head and base 
of cruciform elevation; rostrum with tip piceous, barely reaching 
posterior cox. Lateral areas of abdomen much depressed. Long., 
male 25 mm., female, 23 mm. ; exp. teg. 75 mm. 
Habitat—Kuranda, Queensland; several male and female 
specimens. (Presented by R. W. Armitage, 1908.) 
Allied to M. intersecta, Walk., and M. sylvanella, God. and Frogg., 
but differing in the shorter abdomen and overlapping opercula. 
Differing also from M. extrema, Dist., by the narrower head and 
thorax. The dark fascia on the dorsum renders it easily identifiable.
