624 NEW AUSTHALtAN SfECltS OF CARABit)*, 



than prothorax (12-7 x 6-6niin.), widest about basal fourth; disc 

 lightly concave between fifth interstice of each elytron, edge of 

 this depressed area sharply defined (almost subcarinate towards 

 base) ; sides strongly and subobliquely declivous from edge of 

 discal area; lateral channel wide (particularly near beginning of 

 apical curve); border narrow; a row of small, separate punctures 

 along sides; two or three punctures on basal declivity of each 

 elytron; inflexed margins wide anteriorly, gradually narrowed 

 backwards; apical mucroiies long (l"5mm.), sharply pointed, 

 distant from one another. Intercoxal part of prosternum with 

 a setigerous puncture on each side; basal declivity abrupt. Legs 

 light; four posterior coxae impunctate ; posterior trochanters 

 irapunctate, narrowed, but obtuse, at apex; posterior femur with 

 a setigerous puncture a short distance from apex of trochanter. 

 Length, 25-5; breadth, 6'6mm. 



Hab. — Western Australia. Type in Coll. Sloane. I do not 

 know the exact locality of the type-specimen, which I received 

 from Mr. French; but two specimens were given to me by Mr. 

 H.M.Giles, ticketed " Mundaring, Giles," which, though not 

 so brightly coloured, are evidently conspecific. 



It belongs to the C . mucronatum-gro\iY>, and is closely allied 

 to C. leai SI. It differs from C. mucronahim Macl., (also from 

 the other two species of the group) by eyts more prominent; 

 prothorax with basal sinuosities stronger, basal lobe more de- 

 veloped; elytra with apical mucrones developed into elongate 

 horns. It also differs decidedly from C. mucronatuni by the 

 depressed and slightly concave, discal area of the elytra, which 

 is sharply defined by the fifth interstice becoming subcarinate. 

 It differs from C. leai [from comparison with a specimen {^) in 

 my possession from Onslow, W.A ] by prothorax with border 

 wider, particularly near anterior angle, a flat depression near 

 each anterior angle; elytra with flattened discal area quite black, 

 apex with two long single sharp horn-like mucrones (not with 

 short mucrones, above each of which is a strong obtuse tubercle). 

 From the description of C longipenne SI., it differs by its wider 

 and less elongate form; prothorax more transverse, with border 

 wider, posterior angles evidently less rounded off; elytra more
