C. costatuSf Geb. ; which is much smaller, lighter in colour, 

 with six costae on each elytron, and non-tuberculate elytra. 

 Specimens of costatus were also sent by Mr. Giles from Mun- 

 daring, Western Australia. There is no evident sexual dis- 

 tinction in the specimens. Type in author's collection. 



Cestrinus (Adelodemus) excisicollis, Cart. 



Since describing this species, I have seen two specimens. 

 One from Herr Gebien, labelled "Silver Valley, N. 

 Queensland," is so different that I described it under another 

 name. This insect is smaller than the type, 10 x 4*3 mm. (the 

 type is 15x6 mm.), is of a darker colour, with a smaller and 

 less angulate excision of the base of prothorax. The second 

 specimen, lately sent from the Melbourne Museum, is labelled 

 "Claudie R., N. Queensland," and is intermediate in 

 size and shape of prothorax between the former two. For 

 the present, therefore, I consider them as conspecific, and the 

 species to be variable in size and, to some degree, in form. 

 The sculpture is indistinct, but the definite features are the 

 same in all three specimens. It is apparently — from analogy — 

 a denizen of the "scrub" or "brush" country, and it is very 

 possible that the habitat, Gippsland (as given me by Mr. Giles 

 for a specimen sent me for determination), was erroneous. 

 The type was given to me by Mr. C. French without specified 

 locality. 



CLedius tuberculatus, n. sp. 



Ovate, convex ; brownish-black, clothed with short 

 squamose derm. 



II ead — Epistoma semi-circularly excised in middle, deeply 

 received into the thorax, surface rugose, antennae very short, 

 joints compact, and very little enlarged at apex. Prothorax 

 1"5 x 3 mm., semi-circularly emarginate at apex, widest and 

 bisinuate at base; sides rounded and converging without sinua- 

 tion from base to apex ; anterior angles rounded, posterior sub- 

 rectangular ; margins somewhat •explanate, but not separated 

 or differentiated from the disc ; surface rugose and asperate. 

 Scutellwm not evident. Elytra of same width as prothorax at 

 base, ovate, widest behind the middle, margins not visible from 

 above, covered with short close hair; each elytron with three 

 rows of round, slightly raised, flattened tubercles; under-side 

 rugose punctate, legs short, anterior tibiae curved, widely 

 expanded and clavate at apex, with a wide dentate emargina- 

 tion and some fine serrations on outside edge, other tibiae 

 straight. Dimensions — 6 x 3'5 mm. 



Hab. — Queensland: Townsville (H. Brown).
