Australian and Tasmanian Cryptoccphalidcs. 393 



subtriangular, apex less than half the width of base, base entire. 

 Elytra with large subhumeral lobes ; with deep and fairly large 

 clearly defined punctures, subgeminate in arrangement and becoming 

 smaller posteriorly ; with traces of feeble alternate elevations. Apex 

 oi prosternum wide and feebly bilobed. Fourth segment of abdomen 

 very narrow in middle but not interrupted by fovea ; the latter 

 almost without lateral extensions. 

 Length 3| mm. 



Hah. Queensland : Endeavour River (Macleay Museum), 

 Mackay (G. French). 



The three specimens before me are uniformly coloured 

 and without bluish gloss on the elytra. 



The species differs from the dark variety of Cr. 

 argentatus, Chp., in being larger and with the abdomen 

 pallid ; from Id. nigripcnnis, Baly, it differs in its pro- 

 thoracic margins being less than half the width that they 

 are in that species, and the antennae much thinner ; from 

 vicarius, n. sp., it differs in its shorter and thinner antennge, 

 narrower prothoracic margins and smaller punctures. 



Cryptocephalus appendiculatus, n. sp. 



(^ . Head (front excepted), antennae, extreme base of prothorax, 

 scutellum, metasternum and parts of legs black ; elytra deep metallic 

 bluish-green, elsewhere red. 



Head densely punctate, strigose at sides of and behind eyes. 

 Antennae thin, passing apex of body, second joint less than half the 

 length of third, third slightly shorter than fifth, fifth and eleventh 

 subequal. Prothorax about three times as wide as long ; with 

 comparatively small and rather sparsely distributed punctures, 

 larger and denser at sides than elsewhere ; oblique impressions 

 rather deep ; margins narrow. Scutelluin triangular, apex narrow 

 but truncate, base rather deeply notched. Elytra with fairly large 

 subhumeral lobes ; densely and coarsely punctate, with transverse 

 rugulosities, punctures subseriately arranged and sparser but not 

 much smaller on apical third. Apex of prosternum very wide and 

 feebly bilobed. Two basal segments of abdomen with an oblique 

 ridge commencing on each side of the intercoxal process, diverging 

 hindwards and terminating at the apex of the second segment in a 

 skinny flap, fourth segment not traceable across middle, fifth with a 

 wide shallow impression. 



Length 4 J mm. 



$ . Differs in having thinner antennse, not extending to apex, 

 prothorax more transverse ; subhumeral lobes rather smaller ;
