Australian and Tasmanian C'ryptoccjphalidcs. 409 



Cryptocephalus lilliputanus, n. sp. 

 (Plates XXIir, XXIV, figs. 69, 126, 127.) 



^ . Deep metallic green with a slight coppery gloss ; prothoracic 

 margins, a rather large spot at the apex of each elytron, legs (the 

 two ajjical joints of tarsi iufuscate) and the second and fourth joints 

 of antenna? reddish-testaceous. 



Hcdd very densely but not very coarsely punctate, punctures as 

 large on clypeus as elsewhere, and at base and sides of eyes more 

 or less confluent ; with a transverse and a longitudinal impression. 

 Antennae rather thin, shorter than the body, second joint more than 

 half the length of third, third shorter than fifth. Prothorax less 

 than twice as wide as long, strongly convex ; densely coarsely and 

 regularly punctate ; oblique impressions rather deep ; margins 

 narrow. Scntellum triangular, apex obtusely rounded, base entire. 

 Elytra diminishing in width from base to apex, subhumeral lobes 

 small, densely and moderately coarsely punctate, the punctures 

 somewhat smaller but scarcely subseriately arranged posteriorly, 

 towards base feebly transversely rugulose. Apex of prosternum 

 wide and just perceptibly bilobed. Intermediate segments of abdomen 

 strongly incurved to but continuous across middle. 



Length 2i mm, 



$ . Differs in having the prothorax red, but with a complete 

 transverse median fascia and a complete longitudinal vitta, the latter 

 narrow on its apical and wide on its basal portion ; the antennte 

 are shorter and the elytra are almost as wide at apex as at base ; 

 second and third abdominal segments with almost straight sutures, 

 fourth rather large at sides but scarcely traceable across middle ; 

 fovea larger than usual, without lateral extensions. 



Length 3 mm. 



Hah. Tasmania : Huon River {A. M. Lea). 



Of five specimens before me four are females, of these 

 three have the prothoracic markings as described, in the 

 other the prothorax is coloured exactly as in the male ; on 

 this and another female the front tibite have a blackish 

 streak on their outer apex ; the first and fifth joints of 

 antennse are dark in some specimens and pale in others. 



This is another very small species which would look 

 more at home in Loxopleurus but has the apex of the pro- 

 sternum feebly bilobed. The prothoracic fascia with spurs, 

 the apical segments of abdomen not pale flavous, and the 

 colour of tarsi should distinguish it from Lox. sturmi,
