ON A NEW RHYTIPHORA IN THE NATIONAL MUSEUM, MELBOURNE. 
sex of an unique specimen may be determined. Still, if dallasi is 
without such depressions in the male, quite possibly the male of this 
species is without them. 
At Mr. French’s request, the species is named after the late Sir 
William Macleay. 
RHYTIPHORA MACLEAYI, SP. NOV. 
Black. Densely clothed with white and ochreous pubescence, in 
places glabrous or with black pubescence ; the elytra conspicuously 
striped. 
Head large, with rather coarse but partly concealed punctures, 
with a narrow continuous median line. Antennae of moderate length. 
Prothorax about one-fourth wider than long, transversely rugose. 
Elytra widest across shoulders, sides thence regularly diminishing 
in width to apex, where each is acutely spined ; with four almost 
equidistant feeble but conspicuous elevations on each, the first very 
close to suture, the second terminated at about the apical fifth, the 
third commencing just within the shoulder, and the fourth just below 
it, these two conjoined near apex ; all. these ridges have small granules 
towards the base, sometimes rounded, but often acute, and all have 
coarse punctures gradually decreasing in size posteriorly, but 
smaller on the subsutural ridge than the others ; the margin is 
narrowly ridged and smooth. Length 43, width 15 mm. 
Habitat . — Western Australia : Kookynie. 
The clothing on the head is ochreous, but becomes whitish below

middle there is a narrow black patch, straight on its inner, and 
curved on its outer edge. On the prothorax, the pubescence is 
whitish, but in places more or less deeply stained with ochreous, 
and leaving two curved black transverse lines, a median one not 
interrupted in middle, and a sub-basal one interrupted in middle. 
The scutellum has ochreous clothing, margined with black On
