Talaurinus pulverulentus, Macl. 

 Var. prosternalis, n. var. 



<3 . Of size and general structure of typical specimens ; 

 antennal scape slightly more curved and rather more incrassate 

 at extremity; prosternum with a narrow transverse carina 

 in front of anterior coxae, terminating abruptly at each end; 

 metasternal tubercles situated slightly internal to middle 

 trocanters and nearer to each other than in type. 



9 . Similar to O of typical specimens except that scape 

 is slightly thicker. 



Dim. — S , 11x4 mm. ; 9 > 12 x 5 mm. 



Hah. — Central Queensland: Longreach (A. M. Lea). 



Except in regard to the ridge on the prosternum and the 

 approximation of the metasternal tubercles, this form does not 

 •differ from T. pulverulentus, for the difference in the antennae 

 is slight and only appreciable on careful comparison. In T . 

 pulverulentus the metasternal tubercles are evidently farther 

 apart; they are situated behind and a little towards the outer 

 side of the middle trocanters. 



Type in the South Australian Museum. 



Talaurinus carinattfrons, n. sp. 



d ■ General facies that of T . caviceps. Black, densely 

 clothed above except on elevations with greyish scales, beneath 

 with similar more scattered clothing on middle and sides of 

 each segment. 



Head convex, forehead concave between the ends of the 

 ridges; marked with three ridges, a prominent rounded one on 

 each side, the prolongation back of the external rostral ridges, 

 and a shorter, much finer, and more sharply defined ridge or 

 carina in centre. Rostrum moderately deeply excavate, ex- 

 ternal ridges thick, rounded, slightly convergent basally, con- 

 tinuous with lateral ridges on head ; internal ridges but little 

 prominent, median area little depressed below level of internal 

 ridges, sublateral sulci long, deep and foveiform at base, 

 shallow anteriorly. Scrobes simple, not reaching eyes. Eye 

 subrotundate. Prothorax (5x6 mm.) evenly rounded on 

 sides, ocular lobes moderately well defined, median line not 

 impressed but without granules; disc with numerous discrete 

 rounded granules or tubercles, somewhat irregular in size and 

 distribution. Sides granulate. Elytra (13 x 8 mm.) evenly 

 rounded on sides, apex rather strongly rounded, base gently 

 arcuate, humeri marked by out-turned nodule; with rows of 

 small shallow open foveiform depressions obscured by clothing, 

 each separated from the next above and below by a small 

 nitid granule ; interstices with small rounded somewhat
