228 Mr.F.P. Pascoe on some new Australian Longicornia. 
short semierect hairs; head coarsely punctured, with greyish and whitish 
hairs in front ; prothorax narrower than the elytra, dull white anteriorly, 
then brown and ochraceous; scutellum round, black ; elytra with a few 
distinct punctures only, and three or four granules at the base, no raised 
lines, space round the scutellum, patch at the side behind the shoulder, 
and another flexuous patch posteriorly white, the scutellar and posterior 
patches bordered with black, rest of the elytra ochraceous, speckled with 
small black spots; body beneath and legs with a dense, rough, smoky- 
white pile; antenne entirely black, about two-thirds the length of the 
body. Length 6 lines. 
Differs from Penthea scenica (inter alia) in its entirely black an- 
tenne. 
Rhytiphora Waterhouser. 
R. nigro-picea, pube sparsa, ochraceo griseoque irrorata; elytris basi lineis 
duabus vix elevatis, apice subtruncatis. 
Hab. South Australia (Mr. Waterhouse). 
Pitchy black, with a short pile arranged in little ochraceous tufts, the 
intervals exposing the black derm partially covered with pale-greyish 
hairs; in other words, the whole upper surface is finely speckled with 
ochraceous, grey, and black, the former predominating, and often con- 
fluent so as to form irregular lines; head rather short in front, with a 
mesial line extending from the vertex to the epistome ; antenne shorter 
than the body, grey, spotted with black, a little ochraceous at the base 
only ; prothorax not quite so long as broad, the sides nearly parallel ; 
scutellum subtriangular, the apex rounded; elytra very convex, gra- 
dually receding from the shoulders, the apex subtruncate, the base with 
a few black granules and two scarcely elevated although well-marked 
lines; body beneath and legs reddish ochraceous, spotted with black. 
Length 15 lines. 
One of the largest species of the genus, which, from description, 
might be thought to approach R. polymita, Pasc., in colour ; but in 
that species the pile is perfectly uniform in texture, and every spot 
of the derm is surrounded with pale ashy; in other respects it is also 
more cylindrical, the elytra not so convex, and without the basal 
lines. Altogether it is a very fine and distinct species. 
Monochamus ovinus. 
M. ovatus, fulvo-griseo pubescens, pallide griseo irroratus; capite im- 
punctato; prothorace transverso, lateribus fortiter spinoso; elytris sub- 
trigonatis, apice rotundatis ; antennarum articulis apice nigris, duobus 
basalibus exceptis. 
Hab. South Australia (Messrs. Waterhouse and Odewahn). 
The male shortly ovate, the female more oblong, covered with a short, 
dense, fulvous-grey pile, sprinkled with a very much paler shade of 
nearly the same colour; head rather short, and very convex anteriorly,
