23G XOTES ox SOME AUSTRALIAX TKXEBRIOXIDAE^ 



especially the 7th; the yth (on side) not visible from above; th'i external eostae 

 less wavy than those near suture; the wide depression between eostae of irregular 

 width, the (ith and 7th wider than the rest, and showing- faint, obsolescent, punc- 

 tures; underside smooth, prosternum opacjue. Dimensious: 19 ^ 7 mm. 



Hab. — Moruya, New South Wales (E. H. MacD. Murray). 



Two examples were obtained by !Mr. W. DuBoulay, of which one \va^ kindly 

 given me some years ago. At the time, 1 erroneously identified it as C. hiinierali^ 

 Bates, but the true hiimeralis has lately been clearly identified by the couiteous 

 help of Mr. Blair, to whom 1 sent drawing's of the two species to compare with 

 the tjrpe (no Australian Museum possesses a specimen). Bates's species has a 

 very differently shaped prothorax (.see fig. 7a), while the elytra have 8 uniform 

 < ostae, scarcely, or very feebly, crenulate, with narrow-er sulci of equal width. 

 The only cxamisle T have seen (exce]>t the type, in 1907) was taken at Port. 

 Maequaric by Dr. E. W. Ferguson and generously given to me. The two .sj'ecies 

 are, however, allied and belong to the same section of my tabulation. (X.B. — Tn 

 this section there are no external sexual characters.)

(jbovate, depressed, opaque l)lai-k above, underside nitid. Iltat} with iim- 

 iiouuced stirrup-shaped impression on front, this outlined by deep sulcus; an- 

 tennae very stout, joints oval, 3rd longer than 4th; clyiJeus sub-truncate. Pro- 

 tJiorax — length in middle slightly less than width; widest near front; foliate mar- 

 arins wide and obliquely raised, separated from disc by wide sulcus, anterior angles 

 widely rounded and jiroduced, lateral recurved border moderately wide; sides 

 arcuately converging behind, with a wide notch or excision preceding the acuta, 

 outwardly-directed, hind angles; base sub-angnlate (scarcely coan-tate) ; disc with 

 wide and deep medial sulcus and a short sulcus on each side of this. Scut ell iii-t 

 transverse, with a triangular depression behind it. Elytra widely obovate and 

 rather flat, considerably wider than prothorax at base, shoulders formed by epi- 

 iileural fold sr|uarely I'ounded, each elytron with 9 rather sharply raised nitid 

 eostae, those near suture feebly undulate, 1st to 5th subgeminate, divided by fine 

 sulcate line, the Sth short, extending from half-way to tlie apical declivity, the 9tli 

 starting immediately behind epipleural fold and forming a limiting border to the 

 elytra throughout ; between, the 9th and the epipleural fold a wide convex interval 

 bounded on each side by a row of t'ovento punctures. Underside smooth. le-:rs 

 simple. Dimensions: 21 ^ 8 mm.
