Rhinaria convexieostris, Lea. 



This species is close to tibialis, but differs in being some- 

 what narrower, with the base of the rostrum feebly convex 

 in the middle instead of distinctly carinated, and with the 

 prothoracic punctures larger and more conspicuous. 



In some specimens of tibialis the elytra have somewhat 

 similar markings to this species ; although in the majority of 

 them the markings are much more obscure. 



Rhinaria signifera, Pasc. 

 This appears to be a fairly common Queensland insect. 

 Two specimens from Port Denison differ from the normal 

 form in having the median markings of elytra conjoined at 

 suture and somewhat ochreous instead of white. 



Rhinaria grandis, n. sp. 



Black. Densely covered with variegated scales, and with 

 setae scattered about. 



Head with four large conjoined tubercles between eyes, 

 the hind ones larger than the others, the space between the 

 tubercles deeply hollowed out. Rostrum glabrous and con- 

 cave along middle ; at base deeply concave, distinctly im- 

 pressed along middle towards apex and less noticeably to- 

 wards the sides ; scrobes extended almost to mandibles, and 

 open in front. First joint of funicle about once and one-half 

 the length of second. Prothorax about as long as wide, sides 

 strongly rounded ; closely covered with round and almost re- 

 gular tubercles, many of which are capped with a small shin- 

 ing granule. Elytra rather long, each shoulder with a strong 

 conical granulated tubercle ; with rows of large but more or 

 less concealed punctures ; interstices with numerous granules, 

 especially on the third, fifth, and seventh. Length (exclud- 

 ing rostrum), Iblj-l^h mm.

 tains (E. W. Ferguson). 



The strong humeral and cephalic tubercles and varie 

 gated clothing easily render this the finest known species of 

 the genus. The scales almost everywhere conceal the derm. 

 They are mostly of a muddy-brown or ochreous-brown colour, 

 with on the elytra a wide V-shaped darker patch about the 

 middle, traces of another V towards the base, and an irre- 

 gular triangle on each side of the posterior declivity. On 

 each elytron there is also a round, rusty-red spot on each 

 side of the humeral tubercle, an irregular one before the 

 middle, and a large irregular spot on the posterior declivity.
