Hab.—King's Sound (W. W. Froggatt). 
In four specimens under examination, two (which I regard 
as males) differ from the others in being smaller, with larger 
prothorax, smaller elytra, and with somewhat different abdo- 
men; one of them has the derm almost entirely of a dull 
red colour. 
X. SAGINATA, Pasc. Hab.—S. Australia. 
SYNAPTONYX OVATUS, Waterh. Hab._NW. Australia. 
SUB-FAMILY ATERPIDES. 
PELORORRHINUS AMPLIPENNIS, n. sp. 
Moderately densely clothed with obscure greyish, feebly 
mottled with sooty and brown scales, but nowhere forming a 
distinct pattern. ^ Prothoracic punctures with stout scales 
becoming setose in middle. Rostrum clothed throughout, 
the apex with long bristles: apices of all the joints of the 
funicle with long sete; tarsi with long sete, especially 
noticeable on the claw joints. 
Head densely and in front deeply punctate; a feeble ridge 
(conjoined and slightly raised in front) on each side between 
eyes. Rostrum largely excavated in front, near base with 
a narrow transverse ridge, behind which is a slightly con- 
cave space; flanks coarsely and confluently punctate to 
base, finely in front except on upper portion, which is al- 
most impunctate. Club elongate-ovate, longer than three 
preceding joints combined. Prothorax longer than wide 
(4 x 33 mm.), sides slightly dilated in middle, base not much 
wider than apex; with numerous small granules not very 
clearly seen through clothing. Llytra raised above and fully 
twice the width and four times the length of prothorax, sides 
very feebly diminishing from near base, and not suddenly 
rounded at apex; with regular series of large, shallow, quad- 
rate punctures ; interstices feebly raised, very much narrower 
than punctures, with almost obsolete granules, except for a 
few moderately distinct ones near base and suture. Length, 
18; width, 64 mm. 
Hab.—W.A.: Mount Barker (Macsorley and Lea). 
To the naked eye the prothorax appears to be marked by 
two dusky, longitudinal, slightly curved lines. If Peloror- 
rhinus is to be maintained it may be necessary to erect a 
genus to receive this species and angustatus, and another to 
receive the species described below as Rhinaria aberrans.
