Leptops echidna, W. S. Macl. 



PL xxxviii., figs. 138 to 140. 



On the males of this species the first row of elytral 

 tubercles is sometimes continued almost to the base, instead 

 of degenerating into a carina there ; in the females it is 

 sometimes represented by two or three tubercles about the 

 apical slope, and carinated thence to base. In both sexes 

 the prothorax appears to be invariably largely scooped out 

 on the disc (the middle usually but not always carinated) 

 and the sides are conspicuously dilated from base to near 

 apex. There are numerous specimens (ranging from 18 to 28 

 mm.) in the Museum from Eyre Sand Patch ; but the species 

 also ranges down to 11 mm.; see the following note. 



Leptops acerbus, Pasc. 



PL xxxviii., figs. 133 and 134. 



I have previously (Ann. Soc. Ent. Beige, 1906, p. 323) 

 commented upon two forms, either of which might be acerbus; 

 of these a specimen from Champion Bay is figured at 134 

 on plate xxxviii., and there are others from Beverley before 

 me quite as small (down to 11 mm.). I am now quite satis- 

 fied that these are varieties of echidna; but the specimen 

 without exact locality (fig. 133) is certainly not echidna. 



Leptops biordinatus, Blackb. 



PL xxxvi., figs. 95 to 104. 



Superficially some males of this species strongly approach 

 some males of duponti, but the suddenly terminated inter- 

 mediate carinae of rostrum are at once distinctive. On an 

 occasional specimen the third interstice on each elytron is 

 carinated from base to about summit of apical slope, so that 

 at first glance there is considerable resemblance to some speci- 

 mens of interioris; on one specimen the second and fourth 

 interstices appear like closely-set chains of small beads, the 

 tubercles (or granules) being twice as numerous as on the 

 typical form. A large specimen from Eucla is most certainly 

 without a pair of conjoined tubercles < 16) on the suture near 

 summit of apical slope, nevertheless there is at the position 

 where these should be two minute flattened shining spaces 

 that appear to represent remnants of tubercles.

<"i<3> They are decidedly variable in size on the species.
