disc of the prothorax the transverse corrugations are some- 

 times scarcely or not at all traceable across the middle ; but 

 on other specimens they are quite as strong there as elsewhere.

Uracanthus strigosus, Pasc. 

 PI. xxxii., figs. 23 to 25. 

 According to Pascoe, readily distinguished by its fulvous- 

 grey hairy stripes, with naked intervals. A specimen from 

 Victoria (the type was from New South Wales), labelled by 

 Blackburn as strigosus, has four hairy lines on each elytron, 

 with the intervals subglabrous ; on the prothorax also the 

 clothing has a sublineate appearance. A specimen from 

 Birchip has the lineate appearance much less denned, the 

 elytral clothing being almost uniform, except that on the 

 extreme margins it is denser; but on the prothorax three 

 almost glabrous lines are very conspicuous. A specimen, 

 taken from a wattle tree at Popes Creek, differs in being 

 narrower and smaller (8 lines), with the prothorax somewhat 

 narrower, with the lateral nodes more prominent, and with 

 the three glabrous lines very conspicuously occupying most 

 of the surface, and elytra with but two conspicuous hairy 

 lines, although the others are traceable; its four hind femora 

 are very densely clothed on the under-surface, this being a 

 masculine feature ; each of the three basal segments of its 

 abdomen has a small medio-apical spot of conspicuosly 

 different clothing to the adjacent parts (this also being a 

 male character). The apical spines (fig. 24) are more acute 

 than usual. Another specimen, from Tarcoola, belonging to 

 Mr. French, agrees with the Ropes Creek one, except that it- 

 is slightly larger and with the apical spines of elytra (fig. 25) 

 smaller and closer together. 



Uracanthus marginelltjs, Hope. 

 PI. xxxii., figs. 26 and 27. 

 A specimen from the Blackburn Collection, and bearing 

 his name label as marginelliis, may possibly be that species ; 

 but the elytra are obliquely emarginate at apex, with the ends 

 of the emarginations rounded off and not at all spinose 

 (fig. 26); it was without locality label. Some other speci- 

 mens from South Australia agree with it, others have the 

 emargination even less pronounced, and on one there is a 

 short inner spine (fig. 27). It is not always easy to dis- 

 tinguish this form from bivittatus, whose outer elytral spines 

 (figs. 29 and 30) are often very blunt.
