flattened tubercles, numerous and forming continuous rows on 

 first, third, fifth, and sixth, fewer, larger, and more widely 

 separated on second and fourth, on second about eight, on 

 fourth four to five in number. Sides with numerous rounded 

 nitid granules. Fifth segment with a moderately deep con- 

 cavity occupying the middle two-fourths, with a deeper trans- 

 verse sulcus along posterior margin. Anterior femora not 

 ridged. 



9 . Similar but more robust, head with median carina 

 less evident, third interstice showing tendency to reduplica- 

 tion of the tubercles in the basal half. Beneath convex, fifth 

 segment with irregular shallow transverse impression at ex- 

 treme apex. 



Dim. — S , 21x8 mm. ; 9 •> 21 x 8"5 mm. 



Hah. — South Australia. 



Type in author's collection. 



I have long had a specimen of this species in my col- 

 lection, but merely regarded it as a form of caviceps. The 

 examination of a number of specimens in the South Australian 

 Museum collection at once showed the difference from that 

 species, the tubercles both on prothorax and elytra being con- 

 siderably finer. 



Talaurinus halmaturinus, n. sp. 



d ■ Large, elongate-ovate, general facies that of T. 

 verrucosus. Black, tubercles subnitid, practically without 

 clothing. 



Head strongly ridged on each side above eye, middle of 

 forehead with a feeble longitudinal carina. Rostrum strongly 

 excavate, especially in front, external ridges subparallel, con- 

 tinued on to head ; internal less prominent but distinct, 

 moderately long, convergent; sublateral sulci long, rather 

 deeply impressed, median area depressed. Scrobes ending dis- 

 tant to eye, with a feeble prolongation upwards and backwards. 

 Prothorax (5x6 mm.) evenly rounded on either side, apical 

 margin subtruncate above, ocular lobes feeble; disc with 

 isolated rounded tubercles, rather farther apart in middle. 

 Sides with tubercles becoming obsolete towards coxae. Elytra 

 (12x8 mm.) evenly rounded on sides, base arcuate, humeri 

 marked by out-turned tubercle ; disc with punctures irregular, 

 hardly traceable into strise, also with scattered setigerous 

 granules; with rows of tubercles corresponding to the inter- 

 stices, moderately large, rounded anteriorly, conical and more 

 spinose posteriorly and laterally, the second interstice with 

 four distantly placed, the last on declivity, third interstice 

 with about ten extending just on to declivity, the tubercles 

 isolated but closer together than on second, fourth with two
