be very small, and are normally quite concealed. The sexual 

 distinctions are very slight, the only one that I can detect 

 being a slight difference in the convexity of abdomen. 

 Eighteen specimens (two taken in cop) were beaten from a 

 small tree, with large, serrated, banksia-like leaves at 

 Malanda. 



Cyllorhamphus mimicus, n. sp. 



Black, antennae and tarsi of a dingy-red. Densely 

 clothed with rusty-brown scales, becoming paler on scutellum 

 and on a space (sometimes subtriangular in shape) on the 

 middle of the side of each elytron. 



Head with dense, partially-concealed punctures of 

 moderate size. Rostrum short and stout, subgibbous at base; 

 basal three-fifths with partially concealed punctures, a ridge 

 on each side and a less distinct one in middle ; elsewhere 

 glabrous or almost so, and with distinct punctures. Antennae 

 stout; first joint of funicle as long as second and third com- 

 bined, second as long as third and fourth combined. 

 Prothorax about as long as wide, apical third with two 

 obtuse median ridges, elsewhere with many more or less 

 obtuse tubercles; with dense concealed punctures. Elytra 

 not very wide, subparallel-sided to beyond the middle ; with 

 rows of large, partiall}'' or entirely concealed punctures ; third 

 interstice with two tubercles about middle, and a semi-double 

 one or ridge near base; fifth with three tubercles, and a short 

 but distinct ridge, terminating at summit of posterior 

 declivity; seventh with two or three obtuse tubercles; eighth 

 with a feeble subapical ridge. Prosternum. rather deeply 

 notched in front, and widely depressed to front coxae, with 

 a narrower groove from same almost to hindmargin. Meta- 

 sternum with a large apical fovea. Legs short; femora stout; 

 four front tibiae with small partially concealed serrations. 

 Length, 5-7J mm.

 South Wales: Dorrigo (W. Heron). Type, I. 2724. 



As in the preceding species the tubercular parts some- 

 times appear as fascicles; but it is readily distinguished from 

 that species by its rostrum, elytra, and under-surface. At 

 first glance it has quite a striking resemblance to Orthorrhinus 

 klugii. There is a more or less glabrous space along the whole 

 of the under-surface, and the scales at the sides frequently 

 have a golden, or even a purplish lustre. From some direc- 

 tions the apex of the elytra appears to be terminated by four 

 small tubercles. On one specimen there appear to be but 

 two tubercles on the third interstice, the second and third 

 being narrowly conjoined so as to appear semi-double. Except
