There are probably in Queensland more speeies of beetles than occur in 

 the rest of Australia, and the wealth of life in its coastal districts can be 

 surpassed in but few parts of the world; so far as these are concerned many 

 of the speeies extend into the "Big Scrub" and Illawarra districts of New South 

 Wales, and in the Far North many New Guinea and Malayan forms occur. 

 Comparatively few districts in Queensland have been well worked for beetles; 

 the Brisbane district (including: Mount Tambourine and Moreton Bay islands), 

 Gayndah, Cairns (including Kuranda, Atherton, Malanda, &c.), Roekhampton, 

 Bowen (Port Denison), Cooktown (Endeavour River), Somerset (including 

 Thursday Island), Townsville, and a few other coastal towns have been compara- 

 tively well worked, but the islands north of Brisbane and in the Gulf of 

 Carpentaria, and almost the whole of the western districts, have been greatly 

 neglected. 



Even in the comparatively well-worked districts the smaller species are 

 often overlooked, the passing collector usually keeping a watchful outlook for 

 large or brilliant species; neglecting the minute forms that must be searched 

 for on sea-beaches, amongst fallen leaves, in moss, associated with ants, and that 

 may be seen in enormous numbers during floods. 



Specimens of all the species here described as new are in the collection 

 of the Queensland Museum; many were originally taken by Mr. Henry Hacker, 

 the entomologist of that institution. 



Family NITIDULID^. 

 CYCHRAMUS PICTICOLLIS sp. nov. 



Castaneo-flavous, or flavous, some parts more or less deeply infuscated or 

 black. Moderately densely clothed with subdepressed, ashen pubescence. 



Head wide; with fairly dense and sharply defined but subasperate 

 punctures; labrum rather feebly bilobed. Antennte with third joint thinner than 

 second, and about once and one-half as long; club large, almost twice as long as 

 wide. Prothorax rather strongly and ev-enly convex, base more than twice as 

 wide as the median length, sides strongly rounded and very finely margined, 

 hind angles rounded off, apex about half the width of base, and rather deeply 

 emarginate ; punctures not quite as dense as on prothorax. Scutellum large and 

 semicircular. Elytra, when at rest, with outlines continuous with those of 

 prothorax, sides feebly diminishing in width from near base, apex widely
