Lepidocolaspis acanthomera, n. sp. 



<S . Of a rather dingy castaneous-brown ; appendages 

 somewhat paler. Densely clothed with thin stramineous scales 

 (scarcely setae), somewhat irregularly distributed on elytra. 



Head with dense, normally concealed punctures, except 

 that on clypeus they are not concealed ; with a narrow median 

 line. Antennae passing hind coxae, second joint stouter and 

 slightly longer than third, seventh to eleventh stouter than 

 third to sixth, eleventh about once and one-half the length 

 of tenth. Prothorax across middle slightly more than the 

 median length, across apex slightly less, sides slightly rounded, 

 base not much wider than apex. Elytra almost double the 

 width of prothorax, sides parallel to near apex, with closely 

 set rows of fairly large but partially concealed punctures, but 

 interstices not elevated, and striation apparently absent. 

 Fifth segment of abdomen almost as long as third and fourth 

 combined. All femora acutely dentate. Length, 2J-3 mm. 



9 . Differs in being somewhat stouter, abdomen strongly 

 convex, and with fifth segment much shorter, and its middle 

 encroached upon by pygidium, and by the somewhat shorter 

 appendages. 



Hah. — Northern Queensland (Blackburn's collection), 

 Cairns district (Macleay Museum and A. M. Lea). Type, 

 I. 3402. 



The elytra are usually paler than the prothorax, but are 

 sometimes obscurely mottled, and the mottling is rendered 

 more conspicuous by the absence of clothing from the darker 

 parts, or to the clothing there being of a smoky colour. On 

 the under-surface the clothing is not uniformly distributed, 

 and is denser (and usually of a snowy-whiteness) on the sides 

 of the sterna than elsew^iere. On abrasion the prothorax is 

 seen to have dense and fairly large punctures, but they are 

 normally concealed by the clothing ; some specimens have a 

 feeble remnant of a median carina. The basal joint of the 

 front tarsi of the male is but slightly larger than on the 

 female. 



CUDNELLIA. 



The species of this genus certainly 'look" as if they 

 belonged to the Clidonotides, and to the vicinity of Ghalco- 

 lam,pra, but I shall not question Blackburn's reference of the 

 genus to the Eumolpides. They may be tabulated as follows : — 



A. Elytra with conspicuous rows of strong 



punctures myfitica 



AA. Elytra with much smaller punctures. 



B. Head with minute punctures insulnris 



BB. Head with very distinct punctures. 

 C. Tibiae acutely triangularly armed at 



outer apex a])icalis 



CC. Tibiae not so armed canalicidafa
