Australian and Tasmanian Cryptocephalides. 897 



they are just as dark. The elytra have almost regular 

 interstices posteriorly, but the third and fifth become 

 united at the apical fourth and towards the apex unite 

 with the seventh, towards the base the interstices become 

 very irregular. On all the specimens before me there are 

 traces of a feeble median prothoracic line. 



Cryptocephalus compositus, n. sp. 



^ . Testaceous ; outer half of antennas and flanks of metasternum 

 infuscate. Pygidium and under-surface with moderately dense 

 silvery pubescence. 



Head densely and moderately coarsely punctate, the punctures 

 more or less confluent at sides of and behind eyes. Antennte long 

 and thin, passing body, second joint not quite half the length of 

 third, third shorter than fifth. Prothorax scarcely twice as wide as 

 long ; densely and coarsely punctate, the punctures sparser towards 

 middle of base than elsewhere ; front gibbous and feebly longi- 

 tudinally impressed ; margins very narrow ; oblique impressions 

 rather feeble. SctUellum subtriangular, apex truncate and fairly 

 wide, base rather feebly notched. Elytra short, subquadrate, 

 subhumeral lobes rather small, surface uneven ; with moderately 

 large seriate punctures. Apex of prosternum very wide and feebly 

 bilobed. Intermediate segments of abdomen strongly curved. 



Length 4^ mm. 



$ . Difl'ers in having the head rather less coarsely sculptured, 

 with the antennae scarcely (if at all) passing the body ; abdomen 

 with the third and fourth segments very narrow in middle ; fovea 

 with scarcely visible lateral extensions. 



Length 5 mm. 



Rah. Queensland : Gayndah (types in Macleay 

 Museum). 



The elytra have more or less regular and convex 

 interstices posteriorly, the third and fifth become united 

 at apical fourth and close to apex curve round to unite 

 with the seventh and ninth, towards the base the 

 interstices and punctures become very irregular, with 

 small transverse rugulosities. 



In build somewhat resembling the jDreceding species, 

 but, apart from size and colour, with the antennce shorter, 

 the prothorax much more coarsely punctate, the scutellum 

 wider at apex and the elytra still more uneven.
