COLEOPTEEA.—LEA. 187 



Hah. — Northern Queensland (Blackburn's collection) ; Bribie Island 

 (H. Hacker and A. M. Lea). New South "Wales: Sydney (Lea). — Type, 

 /. 12049 in South Australian Museum ; cotype, C/2275 in Queensland Museum. 



An ordinary-looking species, not as dark as C. planatus, slightly more 

 convex aiid with more sharply defined elytral punctures; larger than C. dimi- 

 diatus, and differently coloured. Some specimens are of a very dark brown, 

 with the paler parts of the upper surface narrow and rather sharply defined ^ 

 others are paler, almost uniformly castaneous-brown, with the paler parts less 

 defined. 



^THINODES VARIABILE sp. nov. 



Colours variable. jModerately clothed with depressed, pale pubescence. 



Head with dense punctures between eyes (these prominent), a narrow 

 impressed line at base, and two impressions in front. Antennae rather short, 

 club briefly elliptic. Prothorax slightly more than twice as wide as long, base 

 gently bisinuate and about one-fourth wider than apex, hind angles acute and 

 slightly embracing shoulders, sides somewhat flattened, rather strongly rounded 

 in front, apex gently incurved to middle, with fairly dense subasperate punc- 

 tures of moderate size, becoming smaller in middle of apex and on sides. Elytra 

 with outlines continuous with those of prothorax, sides strongly rounded beyond 

 middle, with fairly deep punctate striae, the punctures larger towards base and 

 striae deeper towards apex ; interstices rather narrow, the alternate ones slightly 

 more elevated. Litercoxal process of prosternum continued beyond coxae, its tip 

 triangular. Ahdmnen with tip frequently uncovered by elytra; basal segment 

 almost as long as three following combined. Length, 2-2-5 mm. 



Hal). — Queensland: Cairns district (E. Allen, F. P. Dodd, H. Hacker, 

 No. 929, and C. J. Wild) ; Mount Tambourine. New South Wales: Ourimbah, 

 National Park (A. M. Lea).— Type, 1.12051 in South Australian Museum; 

 cotype, C/2276 in Queensland Museum. 



In general appearance like A. marmoratuni on a greatly reduced scale, 

 but elytral markings differently placed, and third and fifth interstices not 

 terminated before apex. The colour varies from a pale dingy flavous with paler 

 markings on slightly infuseated elytra, to almost black with sharply defined 

 markings on elytra. The darker form, one of which is the type, is piceous brown ; 

 muzzle, sides of prothorax, spots on elytra, antenna? (except club), legs, and 

 parts of under surface more or less flavous; there are often eighteen spots on 

 the elytra so placed as to form an irregular circle about the basal half of the 

 suture, a postmedian fascia (the fascia may be composed of connected or discon- 

 nected spots), and a semicircle on each side of base; the most conspicuous spots 

 are on each side of the scutellum, and these form parts of the circle and semi- 

 circles; on one almost black specimen, the only spots on the elytra are those 

 adjacent to the scutellum. The pale form has parts of the head, prothorax, and 

 under surface slightly infuseated (sometimes scarcely darker than the adjacent 

 parts) ; the elytral spots may be disposed as on the dark form, although less 

 sharply defined, or so extended that the basal semicircles are entire instead of
