356 Mr. F. P. Pascoe on some new Australian Longicornia. 
Symphyletes arctos. 
S. elongatus, piceus, pube sparsa grisea tectus ; prothorace oblongo, sub- 
cylindrico; elytris basi spinoso-cristatis, apice emarginatis. 
Hab. Western Australia. 
Elongate, with a short, sparse, greyish pile, spotted with ochreous on 
the base of the elytra; head clothed with close-set whitish hairs, and 
long, scattered hairs of the same colour intermixed and extending over 
the basal joints of the antennz ; prothorax oblong, nearly cylindrical, 
scarcely wider at the base than at the apex; elytra very slightly re- 
ceding from the shoulders, each at the base with four rows of black 
spines, the suture-row of five or six short spines, the next with three 
much longer, the outer two of three or four spines, each shorter and 
more irregular, the apex obliquely emarginate, but the angle on each 
side only slightly produced; body beneath and legs with a lax whitish 
pile; antenn longer than the body, with a loose whitish pubescence, 
very slightly spotted, and with a well-marked fringe beneath. Length 
8 lines. 
This species belongs to the same section of the genus as S. pedt- 
cornis, Fab., but is more nearly allied to S. fumatus (ante, p. 224) ; it 
is, however, a less robust form, with a nearly cylindrical prothorax, 
the base of the elytra much narrower, the pubescence thinner and 
more irregular, and the antenne with a very much longer and laxer 
fringe. The peculiar curve at the end of the antenne is strongly 
developed in both species. 
Symphyletes vicarius. 
S. rufo-piceus, pube sparsa grisea tectus; prothorace breviter subcylin- 
drico ; elytris subtrigonatis, postice granulis subseriatim instructis, apice 
oblique truncatis. 
Hab. New South Wales? (Mr. Macleay). 
Derm pale-reddish pitchy, with a thin greyish pile, spotted with 
ochreous and white on the elytra; head with a deep mesial line, covered 
with rough, mixed ochreous and greyish hairs; prothorax about equal 
in length and breadth, broader than the head, subcylindrical, but a little 
contracted anteriorly ; scutellum transverse, broadly rounded behind ; 
elytra subtrigonate, rounded at the shoulders, the apex obliquely trun- 
cate, the outer angle more produced than the inner, the base with several 
glossy-black granules, arranged somewhat in lines, but none on the su- 
ture, spots of white principally posteriorly, but forming two or three 
narrow interrupted lines towards the apex ; body beneath with a greyish 
pile; legs with a mixed greyish and brown pile ; antenne rather longer 
than the body, semiglabrous, with a short fringe beneath. Length 7 
lines. 
Allied to S. variolosus (Pascoe, Journ. of Entom. i. p. 340); but
