larger and more clearly defined. Elytra much the same Ijut narrower, 

 punctures in the striae no larger but more clearly defined, and on 

 the interstices somewhat larger, sparser and more clearly defined. 

 Length 2 2 2/3 mill. 



Hab. : W. Australia : Albany, Mount Barker (R. Helms); Bridge- 

 town, Swan River (A. M. Lea). 



In general appearance close to pallidm and the preceding species, 

 but realily distinguished from both by the elytral clothing (the 

 patch on the middle is generally noticeable even on partially abraded 

 specimens). From the preceding species it also differs in the quite 

 evenly curved rostrum, and there is a greater difference in the 

 disparity of the eyes in the sexes take in (3n the preceding species 

 many of the punctures on the interstices are traceable with difficulty, 

 but on the present one they are all (at any rate towards the base) 

 sharply defined. 



The antennae of the nine specimens before me are entirely pale. 

 The basal half of the rostrum is sometimes feebly impressed longi- 

 tudinally. 



SEDIANTHA n. g. 



Head rather small Eyes small, oblique, coarsely faceted, close 

 together above, widely separated below. Rostrum stout, dilated to 

 apex, moderately curved, scrobes subterminal. Antennae not very 

 long; two basal joints of funicle longer than the others; club rather 

 briefly ovate. Prothorax transverse, sides strongly rounded, middle 

 of apex of lower surface deeply and almost triangularly notched. 

 Scutellum absent. Elytra not much wider than prothorax. Metaster- 

 num along middle scarcely half the length of the following segment. 

 Two basal segments of a6(io//it'n large, the two following very short. 

 Legs much as in Desiantha. Body apterous. 



In Blackburn's table of the Erirrhinides this genus should be 

 placed with Desi a7itha s.nd Anorthorldnus, from both of which it is 

 readily distinguished by the absence of a scutellum and the shape 

 of the eyes. It is also apterous, whilst the species of those yenera 

 (at any rate D. maculata and A. apicalis) are winged. In general 

 appearance the species described below looks like a rough Desiantha. 



630. SEDIANTHA MARITIMA n. sp. 



Black; antennae tarsi and tibial hooks reddish. Moderately densely 

 (denser on the prothorax than elsewhere) clothed with stout muddy 

 brown scales, very feebly variegated in places, and thinner on the 

 under-surface and legs.
