Mr. F. P. Pascoe on some new Australian Longicornia. 357 
in that species the elytra (inter alia) are somewhat parallel, incurved 
behind the shoulders, and their apices rather narrowly emarginate. 
Symphyletes satelles. 
S. flavo-castaneus, nitidus; elytris subangustatis, lineis elevatis nullis, 
basi spinosis, pone humeros plaga nivea, apice recte emarginatis. 
Hab. Western Australia. 
Yellowish chestnut, shining, nearly glabrous above; head rather 
narrower than the prothorax, sparingly punctured ; antennz a little 
longer than the body, thinly fringed beneath ; prothorax subtransverse, 
nearly cylindrical, slightly corrugated in the centre; scutellum rounded 
behind; elytra rather narrow, slightly decreasing from the shoulders, 
the base with several concolorous obtuse spines, the apex transversely 
emarginate, the angles scarcely produced, the sides with an ill-defined 
snowy stripe or patch behind the shoulders ; body beneath with a sparse 
pale-ochreous pile, spotted with brown on the postpectus ; legs nearly 
glabrous, except the extremities of the tibiz and the tarsi. Length 
5 lines. 
In some of its characters this species is somewhat intermediate 
between S. derasus and S. egenus, agreeing with the former in the 
absence of the elevated lines on the elytra, which more particularly 
distinguish the latter, and, on the other hand, agreeing with S. eyenus 
in the obsolete or nearly obsolete patch at the sides which is so 
marked in S. derasus as well as in many other species of this genus. 
From both it differs in its narrow elytra, spined at the base and 
transversely emarginate at their apices, and smaller size, although 
this last is a character which at present cannot be strongly in- 
sisted on. 
TPHIASTUS. 
Caput antice transversum, infra oculos dilatatum, tuberibus antenniferis 
robustis et prominentibus, basi approximatis. Prothorax turgidus, lati- 
tudine longitudini equalis, antice constrictus. Elytra subtrigonata, 
basi subbigibbosa, humeris prominulis, rotundatis. Corpus robustum. 
Ceeteris ut in Symphylete. 
The habit of this fine Longicorn is so much at variance with Sym- 
phyletes, to which genus I originally referred it, that I have felt con- 
strained to propose its separation, although the characters given 
above can only be considered as those of that genus, as it stands at 
present, considerably exaggerated. The type is 
Iphiastus heros. (Pl. XVI. fig. 4.)
