HELLUARCHUS ROBUSTUS, Shane. 

 (Plate IX. ; fig. 2). 

 Helluarchns robustus, Sloane, Proc. Linn. Soc. N.S. Wales xxxix., 1914, p. 593. 



The figure of this very unique species is prepared from a topotvpe collected at Ankertell, West 

 Australia. 



Its measurements are — Length 38 mm., breadth 15 mm. 



Mr. Sloane points out in the paper quoted that " The strangely shaped elytra of Helluarchns, 

 which are those of an integripenne and not a txuncatipenne, make this one of the most abnormal forms 

 to be found amongst the Carabidae, and place it quite by itself. Its affinity is evidently towards 

 Helluapterus. In general appearance H. robustus resembles the genus Cuneipectus."
