edges finely sei'rated, suture raised and punctate forming a 

 duuble costa on posterior two-thirds, widening towards the 

 base, four costse distinct throughout the greater part of their 

 length, smooth, the first entire ; the second starting behind 

 the confused humeral region, interrupted by the discal impression, 

 and joining the first near apex; the third shorter than preceding, 

 starting behind the humeral callus, terminating on apical declivity; 

 the fourth near and parallel to sides, starting behind the shoulder 

 and continuous to apex, near but not joining the first; the de- 

 pressed portions of elytra closely and clearly punctate (the punc- 

 tures larger than in C. australasve Saund.; humeral callus grossly 

 punctate). F/osfernu)// with a wide central depression, its 

 process rounded at apex, coarsely punctate in middle, trans- 

 versely rugose at sides, meso- and metasternum coarsely and 

 sparsely punctate, basal segment of abdomen widely and 

 triangularly excised, second segment slightly depressed or 

 flattened in middle, whole abdomen closely finely punctate, 

 ( 9 vvith some smooth bluish impressions along the margins 

 of segments, ^ with a wide triangular excision at apex of abdo- 

 men.) Dimensions : ^, 25 x 8^ mm.; ^j ^-2 ^ ^ nim. 



/^a6. — Kalgoorlie, West Australia(Mr. F. H. Duboulay). 



Two specimens, the sexes, purchased from Mr. Duboiilay, 

 differ from all described s])ecies in having only one distinct 

 impression on anterior portion of each elytron (beyond some 

 confused and confluent humeral impressions. In C. elonyata 

 Waterh., the single impression is behind the middle. The 

 male specimen has little or no pubescence on its upper sur- 

 face, probably through abrasion, showing golden markings 

 where the female shows yellow pubescence; the underside of 

 the male is golden while that of the female is green. There 

 are other minor differences of sculpture. 



Types in the author's coll. 



Having examined further specimens in the Australian 

 Museum, and in Mr. Duboulay 's collection, I find, in two 

 male specimens, a faint indication of a second postmedian 

 impression, on the second costa, partly interrupting it.
