Australian and Tasmanian Cryptocephalides. 427 



In build much the same as -S'. coccineus, Chp., but (apart 

 from colour) readily distinguished by its shorter and more 

 quadrate scutellum, with the basal notch deeper ; the 

 punctures on the head are also very different. In the 

 three specimens before me the punctures on the prothorax 

 vary considerably in number, on one specimen being very 

 sparse, on another fairly numerous, but they appear to be 

 always sparser on the disc than elsewhere. 



SCHIZOSTERNUS TRILINEATUS, n. sp. 



(Plate XXIV, fig. 85.) 



$ . Head (base black) and prothorax testaceous, elytra (extreme 

 base and three stripes black) and legs (tarsi and apices of tibiae black) 

 somewhat paler, intercoxal process and abdomen flavous ; antennae 

 black ; metasternum blackish, in parts testaceous. 



Head densely and coarsely punctate. Antennae thin, second joint 

 less than half the length of third. Prothorax not once and one-half 

 as wide as long ; sides near apex suddenly and deeply constricted so 

 that the anterior angles project outwards ; with moderately large 

 irregularly distributed punctures ; disc somewhat gibbous ; oblique 

 impressions feeble. Scutdlnm subquadrate. Elytra rather long and 

 parallel-sided, subhumeral lobes small ; rather densely and coarsely 

 punctate, the punctures becoming subseriate in arrangement 

 posteriorly. Pygidium densely and rather finely punctate, and with 

 a feeble median ridge. Apex of prosterimm triangularly excised. 

 Fourth segment of abdomen hidden in middle ; apical fovea large, 

 deep, and without lateral extensions. 



Length 4 mm. 



ffab. N. S. Wales (type in Macleay Museum). 



The three dark elytral stripes are parallel-sided, but at 

 the apex they become conjoined, the sutural is narrower 

 than the lateral ones ; the subhumeral lobes are coloured 

 as the disc. In the type the two terminal joints of the 

 antennae are missing. 



SCHIZOSTERNUS MARMORATUS, n. sp. 



(Plates XXIV, XXV, figs. 86, 128, 172.) 



9 . Flavous ; under-surface and legs obscurely mottled with brown; 

 antennae testaceous ; head with the vertex and a median line brown; 

 prothorax and elytra with chocolate-brown or purplish markings ; 

 base of scutellum and of elytra narrowly black. Flanks of abdomen 

 and of metasternum and the pygidium rather densely pubescent.
