some fluids the darker stripes (especially on the elytra) would 

 lose their ochreous meal and become less conspicuous. 



In appearance somewhat like micans, but outline of 

 elytra not almost continuous with that of prothorax, and 

 the clothing more conspicuously bicolorous. In shape it is 

 much like ilium inatus and vittatus. 



Iptergonus, n. g. 

 Eyes strongly convex and projecting, owing to constric- 

 tion of head immediately behind them. Elytra without sub- 

 humeral tubercles. Intercoxal process of mesosternum 

 rounded. Body very short and compact. Other characters 

 as in O-ryops and Gonipterus. 



This genus is proposed to receive a number of small and 

 very robust species, which differ from Gonipterus in the ab- 

 sence of subhumeral tubercles, and from Oxyops in the simple 

 mesosternum. The type of the genus is Gonipterus cionoides, 

 Pasc. ; but I also refer to it Oxyops aherrans, Lea. To judge 

 from the description Oxyops hyperoides, Pasc, belongs to it, 

 and Ootyops turhidus, Pasc, may also do so. 



The Australian genera of Gojiipterides may be tabulated 

 as follows : — 

 Tarsi three jointed ... ... ... ... Syarhis. 



Tarsi four jointed 



Club continuous with funicle . . ... Bryachus. 



Club not continuous with funicle. 



Eyes not prominent... ... ... ... Pantoreites. 



Eyes very prominent. (D 



With a distinct tubercle on each side 



near base of elytra (2) ... ... Gonipterus. 



Without such a tubercle. (3) 



Intercoxal process of mesosternum 



produced ... ... ... ... Oxyops. 



Intercoxal process not produced. Iptergonus. 



Iptergonus bifurcatus, n. sp. 

 Reddish-castaneous, under surface darker in parts; 

 claws black. With snowy-white scales on head, forming three 

 lines on prothorax, and lines at sides of elytra, dense on 

 scutellum and parts of under surface and legs; elytra with 

 several fascicles of white or ochreous scales. Rest of surface 

 with scattered setae or scales. 



(1) In several species of Oxyops the eyes are but little moi-e 

 prominent than in Pantoreites, but the two genera are otherwise 

 very distinct. 



(2) Not on the shoulder, which, however, is often more or less 

 tuberculate. 



(3) In Oxyops, a tubercle is sometimes present near the base, 

 but these species differ from Gonipterus in having the mesosternum 

 produced.
