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 Valley, 

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

 posterior, which are somewhat darker. 



Phobacantha [Cerambycidse]. 

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



Phoracantha superans. 



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

 elongata recta; elytris elongatis parallelis, pallide fulvis, basi mar- 

 ginibusque castaneis, apice bispinosis. 



Hub. Tasmania. 



Dark brown ; head small, with shallow confluent punctures, an im- 

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

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

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

 spine; scutellum small, triangular; elytra broad, a little depressed, 

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

 margins dark chestnut-brown, thickly and deeply punctured, gradually 

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

 elytron with two smooth elevated lines, not extending to the apex, and 

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

 silky hairs on the tibia? and tarsi ; antennae ferruginous, covered with 

 a close greyish 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 Phoracantha 

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

 elytra varies. 



Ceeesittm [Cerambycidse]. 



Newman, Entom. p. 322. 



Ceresium apiculatum. 



C. luteum, subnitidum, punctulatum ; elytris lateribus piceis, apice 

 singulatim acuminatis. 



Hub. Moluccas (Batchian). 



Reddish yellow, shining, nearly free from pubescence, covered with 

 numerous small punctures ; head not prolonged in front, a short im- 

 pressed line between the antennae ; prothorax subparallel, darker at the 

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

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

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