the Australian Longicornia, 539 



coarsish white pile, spotted irregularly with black ; femora covered 

 with a white pile, except at the apex ; tibiae black, with a white 

 band in the middle ; tarsi white, the last joint and claws black. 



Length 13 lines. 



This species differs in very few points from Penthea vermicularia, 

 Don., and is perhaps only a local variety. The three small but 

 sharply prominent tubercles on the side of the prothorax, how- 

 ever, and the continuous lines on the elytra not broken by the pre- 

 sence of tubercles, which seem to make up those lines on P. vermi- 

 cularia, are sufficiently distinctive to warrant its separation. 



2. Penthea costata. 



P. picea, fere glabra ; prothorace transversim rugoso ; elytris 

 fortiter bicostatis, interspatiis et margine laterali pube alba 

 griseo-varia. 



Sydney. 



Pitchy, nearly glabrous, except on the middle and sides of the 

 elytra, and beneath ; head with an impressed line on the vertex, 

 and a slightly raised line on each side of it, a few small punctures 

 principally in front ; antennae pitchy, the third and some of the 

 succeeding joints faintly tinged with white ; prothorax transversely 

 rugose, the sides feebly tuberculate ; scutellum scutiform ; elytra 

 broadest at the shoulder, then slightly incurved, and again becom- 

 ing nearly as broad as at the base, the surface undulating and 

 marked, particularly at the base, with tubercles and punctures, 

 two very strong costae on each, the spaces between them and on 

 each side, the suture posteriorly and the external margin, with a 

 short silvery white pile, mottled with greyish ; body beneath and 

 legs pitchy, speckled with white hairy patches. 



Length 11 lines. 



I have seen only one specimen of this species. The peculiarly 

 glabrous condition of the upper surface, it may be suspected, may 

 be due to abrasion. From the similarity of the pattern on both 

 sides I think not. In any case it is a very distinct species. 



3. Penthea pullina. 



P. ferruginea, vel rufo-fusca, pube grisea, fulvo-varia ; pro- 

 thorace medio vix rugoso ; elytris bicostatis, costis tuber- 

 culato-interruptis. 



Western Australia. 



Ferruginous, sometimes very dark or nearly brown, with a thin 

 apparently very deciduous pubescence, principally on the elytra,
