so we may expect to find the same variations in the present. Beyond 

 this, I see nothing to justify its separation from that genus. My 

 example of Sthelenus ichneumoneus, Buq., is from the Amazon Yalley, 

 and differs in this respect, that the legs are concolorous, except the 

 posterior, which are somewhat darker. 



Phobacantha [Cerambycidae]. 

 Newman, Ann. and Mag. Nat. Hist. v. p. 19 (1840). 



Phoracantha superans. 



P. fuscus ; prothorace parvo, subsequali, leviter rugoso, spina laterali 

 elongata recta; eljtiis elongatis parallelis, pallide fid\as, basi mar- 

 ginibusque castaneis, apice bispinosis. 



Sab, Tasmania. 



Dark brown ; head small, with shallow confluent punctiu'es, an im- 

 pressed line between the eyes ; protborax small, subequal, covered with 

 coarse confluent pimctures, an elliptical space, on the median line near 

 the base, smooth and shining, the side with a slender, elongate, straight 

 spine ; scutellum small, triaugulai' ; elytra broad, a little depressed, 

 five times as long as the protborax, pale fulvous yellow, the base and 

 margias dark chestnut-brown, thickly and deeply pimctm-ed, gradually 

 decreasing in size and proximity as they approach the apex, each 

 el;yti"on \di\\ two smooth elevated lines, not extending to the apex, and 

 terminating iu two long acute spines; legs ferruginous, with yellow 

 silky hairs on the tibiae and tarsi ; autennte ferruginous, covered with 

 a close grej-ish pubescence, except the basal and second joints, the 

 third to the seventh inclusive armed with a spine at the apex ; body 

 beneath pitchy, pubescent. Length 10 lines. 



Very distinct, and not to be compared with any other Plioracantha 

 that I am acquainted with. The amount of chestnut-brown on the 

 elytra varies.

Hah. Moluccas (Batchian). 



Reddish yellow, shining, nearly free fi-om pubescence, covered with 

 numerous small pimctm-es ; head not prolonged in fi-ont, a short im- 

 pressed line between the antenna) ; protborax subparallel, darker at the 

 sides, rather longer than broad ; scutelhmi subcordate ; elytra slightly 

 lobed at the shoulder, rather depressed, parallel, the apex of each ter- 

 minating in a sharp submedian point, irregularly punctiued, the sides
