short erect black l)ristles " (Ann. Mag. Nat. Hist. Ser.4, Vol. v., 

 p. 99). This specimen, which is exactly similar to one sent by- 

 Mr. Duboulay, junr., to me from West Australia (unlabelled), is 

 furnished above with distinct red bristles, but otherwise corres- 

 ponds to the description. I am unwilling to doubt the evidence 

 of so accurate an entomologist as the veteran Curator, and have 

 written to the British Museum for information on this point. 

 In reply, Mr. Gahan writes, " //. Mastersi Pasc, has distinct 

 bristles of a rather darkish or rusty reddish colour, not black." 



H. sparsus Gavt., [infra) is particularly interesting as forming 

 a link connecting Sections ii. and iii., having the long tufts of 

 hair as in Section ii., with the bicostate elytra of Section iii. 

 There are two specimens in the Melbourne Museum, identified 

 by myself. 



Section iii. Elytra bicostate (siiture sometimes costaie). 



A. Size large, 20-24 mm. long, elytral costse not (in general) parallel 



(subparallel in H. moniliferus) . 



B. Form widely ovate, margins wide. 



C. Elytra widest at base consularisVn.s,G. 



CC. Elytra widest at, or behind, middle. 



D. Colom- brilliant nitid-black, prosternum not carinate. 



spinifer, n.sp. 



DD. Colour subnitid-brown, prosternal carina sharp. 



monili/erus Pasc. 

 BB. Form elongate, elytral margins narrower. 



C. Elytra glabrous. 



D. Elytral costse extending nearly to apex of disc, prosternal 



carina bifid at apex ellipticus Lea. 



DD. Elytral costte terminating on apical declivity, prosternal 



carina subobsolete anteriorly approximate, n.sp, 



CC. Elytra sparsely pilose, hairs long comatus, n.sp. 



CCC. Elytra squamose. 



D. Anterior prothoracic processes rounded at apex, elytral 



costfe terminated on apical declivity sqiiamosus Pasc. 



DD. Anterior processes acute at apex, elytral costse con- 

 tinued almost to apex Derbyensis MacL 



AA, Size medium, 15-18 mm. long. Elytral - costte parallel or
