patches of whitish pile, the prothorax with a broad greyish stripe on 
each side; head deeply sulcated between the tubers, pubescence greyish, 
and chiefly below the eyes; prothorax with a glabrous central line on 
the disk, slightly gibbous on each side, the greyish stripe, formed of 
close-set hairs, very broad and embracing the spine; scutellum trans- 
verse ; elytra with an elevated line between the lateral carina and the 
suture; body beneath glossy black, with whitish hairs chiefly at the 
sides ; legs covered with a pale-greyish pile; antennz black, with long

CoRRHENES. 
Caput latitudine vel fere latitudine prothoracis, antice transversum, tuberi- 
bus antenniferis validis, basi distantibus. Ocwli fere divisi. Antenne 
corpore breviores, paulo incrassate, scapo subcylindrico, articulo tertio 
longiore, quarto breviore, ceteris brevioribus. Prothorax quadratus 
vel subquadratus, ad latera dente antico. Elytra subangustata, integra. 
Pedes fere zequales in utroque sexu. Zursi lineares, vel articulo penul- 
timo preecedente vix latiore. Pro- et meso-sterna elevata. 
The type of this genus is the Saperda paulla of Germar (Linn. 
Entom. ii. p. 230), but which, on account of its toothed prothorax 
and elevated prosternum, should be referred to the vicinity of M- 
phona, Muls. From this and other allied genera Corrhenes differs 
either in the third antennary joint exceeding the fourth in length, 
or in its narrower prothorax (which is very little, or in some species 
not at all, broader than the head), and its single prothoracic tooth. 
In the 2nd and 3rd series of the Transactions of the Entomological 
Society I have published three species; these, with C. paulla and the 
one described below, comprise all the members of this group known 
to me. 
Corrhenes quttulata. 
C. murino-fusca; antennis haud annulatis; capite albo notato ; prothoracis 
vittis duabus elytrorumque guttulis numerosis*albis. 
Hab. New South Wales? (Mr. Macleay).

slender erect hairs intermixed ; head with large white spots; prothorax 
with a well-marked lateral tooth, the disk with four waved longitudinal 
white lines, the two lateral feebly marked ; scutellum rounded behind ; 
elytra sparingly punctured with several small, well-defined white spots ; 
body beneath with a thin mixed white and grey pubescence; femora 
and tibize spotted with white, the pubescence on the tarsi almost entirely 
white ; antennze at the base brownish, with white spots, then whitish, 
becoming darker towards the apex. Length 6 lines.
