74 Mr, Arthur M. Lea's Revision of the 



level of the costae, as can plainly be seen on viewing 

 the insect along the elytra; the elytra also have both the 

 suture and the outer margins pallid to the extreme base * 

 not as in paradoxa the suture black and the outer markings 

 not continuous to base. Nevertheless it is possible that it 

 will afterwards have to be placed as a variety of faradooca, 

 especially as the type of the latter was from a mount- 

 ainous district and therefore especially liable to melanism. 



Metriorrhynchus simplicicornis, n. sp. 



$ . Black ; basal three-fifths of elytra reddish-testaceous. 



ilearf i^olished. Eyes large. Rostrum absent. Antennae serrate, 

 passing pallid portion of elytra ; 2nd joint rather distinct, .3rd dis- 

 tinctly longer than 4th, none of the others transverse. Prothorax 

 moderately transverse, apex rounded, sides constricted in middle, 

 posterior angles very acute ; with a strong median areolet continuous 

 almost to apex, from its middle obscurely connected with each side. 

 Elytra narrow and ^^^'rallel-sided ; quadricostate, the interstices 

 each with a single row of large rectangular punctures, becoming 

 irregular at base and aj^ex. Abdomen with penultimate segment 

 widely and semicircularly but not very deeply excised in middle. 



Length 6 mm. 



ffab. Queensland : Mount Tambourine (type in R. 

 Illidge's collection). 



In appearance closely resembles the following species 

 (which also has the elytral punctures in single series) but 

 with antennae serrate only. I am not sure whether 

 Waterhouse would have regarded the prothorax as 3- or 

 5-areolate ; if the former it would have been referred to 

 Stadenus, if the latter, to S^jnchonnus. 



Metriorrhynchus ramosus, n. sp. {Fig. 23.) 



(^. Black; basal tliree-fifths of elytra reddish-testaceous. 



Rostrum absent. Antennae distinctly passing middle of elytra, 

 strongly Habellate ; 3rd joint not much longer than 4th, its ramus 

 about once and one half the length of the joint itself, of the others 

 (except the 10th) the ramus in each is about twice the length of 

 the joint, 11th about twice the length of 10th. Prothorax 

 moderately transverse, distinctly 7-areolate, apex rounded, sides 

 constricted in middle, basal angles acute and laterally jJroduced. 



* The pallid markings, except at the apical 5th, are confined 

 strictly to the thickened suture and margins.
