50 STUDIES IN AUSTRALIAN EMTOMOLOGY, 



In the following notes I Lave not attempted to give a complete 

 diagnosis of the previously desciibed genera, but the short note 

 on each will be sufficient for their determination. 



Genus Eurylychnus, Bates. 



This genus has been formed by Mr. H. W. Bates [Ent. Mo. 

 Mag. 1891 (2), II. p. 285], whose lamented death has been reported 

 since these notes were written, for the reception of a small 

 insect belonging to the Broscini from Mt. Kosciusko, which he has 

 named E. olliffi. 



The leading characters of the genus, as I regard it, are the 

 following : — 



Head with strong frontal impressions ; a strong transverse 

 impression behind the eyes ; eyes round and prominent, a single 

 supra-orbital puncture above each. Mandibles stout, sharply 

 hooked at apex, a setigerous puncture in the scrobe. Antennae 

 raoniliform. Palpi thick, apical joint truncate. Elytra striate. 

 Anterior thighs short, dilated, but without dentiform projection 

 below in ^ ; anterior tarsi with three basal joints obliquely 

 produced externally, and in the ^ either clothed below with 

 spongiose tissue or not. 



I know of three species belonging to this genus which may be 

 divided as follows : — 

 a. Elytra with scutellar stride : size large E. blagravii, Casteln. 

 aa. Elytra without scutellar striole : size 

 small. 



Prothorax subcordate, gently 

 narrowed behind. Prosternum 

 without a border along anterior 



margin E. victorice, Sloane. 



Prothorax orbiculate, very shortly 

 narrowed behind. Prosternum 

 with a complete border along 

 anterior margin E. olliffi, Bates.
