Mr. F. P. Pascoe on some new Australian Longicornia. 367 
greatest objection to its alliance with Stenoderus is the form of its 
antenne. It must, however, be recollected that several Australian 
groups in this direction are very isolated, as, for example, T’vropis, 
Tricheops, Bardistus, Diotima, and others. 
Chaodalis Macleayi. (Pl. XVI. fig. 1.) 
C. ater, infra subnitidus; elytris, prothoracisque vittis duabus, aurantiacis ; 
tibiarum basi et tarsorum articulis primo, secundo et quarto basi flavis. 
Hab. New South Wales? (Mr. Macleay). 
Black, beneath glabrous and subnitid; the elytra and an irregular 
stripe on each side of the prothorax of a beautiful orange ; the tibie at 
their junction with the femora, and all the joints of the tarsi at the base, 
except the third, pale yellow; head clothed with a deep-black velvet 
pile; on the vertex two, and below each tuber a patch of rich metallic 
yellow hairs ; face above the epistome nearly glabrous; prothorax nearly 
equal in length and breadth, strongly toothed at the sides, and above 
each tooth an elevated tubercle in the line of the orange stripe; scu- 
tellum triangular ; elytra flattened, and rather dilated posteriorly, with 
short, roughish hairs, chiefly at the sides and shoulders, each elytron 
with six (including the two marginal) elevated lines, the interstices 
finely punctured ; femora nearly glabrous; tibiee and tarsi with short, 
stiffish hairs; antennee, except a few rather scattered hairs at the base, 
nearly glabrous. Length 7 lines. 
Psilomorpha lusoria. 
P. rufo-aurantiaca; elytris apice cyaneo-chalybeatis; pedibus nigris, 
femoribus tibiisque anticis aurantiacis; antennis nigris, articulis quarto 
et quinto basi rufescentibus. 
Hab. New South Wales ? (Mr. Macleay). 
- Reddish orange ; the elytra paler, but at three-quarters of their length 
becoming black, then quickly passing into steel-blue to the apex; abdo- 
men dark brown, with a silvery-white shade, very finely and closely 
punctured; legs black, the anterior femora and tibiz orange; antennz 
rather longer than the body, black, with the fourth and fifth joints 
reddish at the base. Length 5 lines. 
Resembles P. apicalis, Pasc., but at once distinguished by its 
anterior femora and tibiz being orange-red. A very good figure is 
given of the type (P. tenuipes, W. Wilson Saunders) in the ‘ Transac- 
tions of the Entomological Society,’ ser. 2. vol. i. pl. 4. fig. 1. 
Ametrocephala mira. 
A, brunneo-rufa, subglabra, capite elytrisque postice nigris, his medio
