 ately rounded at base; with rows of rather large more or less

Hah. — Western Australia: Vasse River (A. M. Lea). 



The edentate femora are as in sculptilis, auchmeresthes, 

 and the following species, all of which, however, are without 

 a distinct scutellum. It is the only species known to occur in 

 Western Australia. The scales are mostly fawn-coloured, the 

 sooty and whitish ones are usually in feeble irregular spots. 

 On the prothorax the scales are larger than elsewhere. There 

 are no distinct fascicles, but the elytra have some sooty scales 

 compacted on a feeble tubercular swelling on the third inter- 

 stice near base, and on the fourth about the middle.

EXITHIUS TRICARINATUS, n. Sp. 



Black ; antennae and tarsi of a rather bright-red. Densely 

 clothed with sooty scales, variegated in places with ochreous. 



Head with coarse punctures, quite concealed in front. 

 Eyes rather small. Rostrum rather stout, sides lightly in- 

 curved to middle ; with dense and coarse punctures, concealed 

 about base ; base tricarinate, median carina stronger than the 

 others and continued for a short distance in front of antennge. 

 Scape shorter than usual, inserted slightly nearer base than 

 apex of rostrum, scarcely half the length of funicle and club 

 combined. Prothorax rather feebly transverse, sides moder- 

 ately rounded ; with dense more or less concealed punctures ; 

 with a very feeble median carina. Elytra about once and one- 

 third as wide as long, sides strongl}^ rounded, base rather lightly 

 trisinuate ; with rows of large partially-concealed punctures ; 

 alternate interstices feebly elevated, the second feebly elevated 

 and shining at base. Mesosternal receptacle strongly elevated. 

 Metasternal episterna not continuous throughout. Basal seg- 

 ment of abdomen flat across middle, its suture with second 

 strongly curved in middle and deep at sides. Femora stout, 

 edentate. Length, 3J mm.

 Island (A. M. Lea). 



In general appearance like small specimens of hrevis or 

 inamahilis, but femora edentate. On the types the ochreous 

 scales are almost absent from the prothorax, on the elytra there 

 are a few feeble spots scattered about, and a feeble transverse 

 row of same at summit of posterior declivity; there is also a
