and partially concealed in front. Rostrum rather long and 

 thin, sides very feebly incurved to middle, shallowly notched 

 on each side of base; with dense clearly-defined punctures of 

 moderate size, becoming larger towards and partially con- 

 cealed on basal third. Scape inserted about three-sevenths 

 from apex of rostrum. Prothorax rather lightly transverse, 

 sides strongly rounded, apex about half the width of base; 

 with dense, round, partially-concealed punctures; with a 

 feeble impunctate median line. Elytra robust, sides 

 moderately rounded, base trisinuate; with rows of large, sub- 

 oblong, partially-concealed punctures; second to seventh 

 interstices with feeble tubercles, supporting feeble or moderate 

 fascicles; a few granules about scutellar region. Mesosternal 

 receptacle feebly elevated. Metasternal episterna rather wide. 

 Femora stout, four posterior strongly, the others rather feebly 

 dentate. Length, 7 J mm. 



Hah. — Tasmania: TJlverstone (A. M. Lea). 



In general appearance rather close to Nechyrus legitimus, 

 but mesosternal receptacle cavernous. In size, and to a cer- 

 tain extent in appearance, fairly close to the preceding species, 

 but with head evenly convex throughout (although with 

 punctures coarser in front than behind) and mesosternal re- 

 ceptacle less elevated in front, with its emargination deeper. 

 The clothing also is more conspicuously variegated. On the 

 prothorax the scales, for a rather wide space along the middle, 

 are mostly sooty, on each side they are mostly fawn-coloured, 

 but with a distinct paler spot close to the dark patch; on 

 the basal half of the elytra they are mostly sooty, on the 

 apical half mostly fawn-coloured, but largely mixed with 

 whitish at summit of posterior declivity. On the abdomen 

 and head they are entirely sooty. As the basal segment of 

 its abdomen is flat in the middle the type is probably a male. 



EXITHIUS TENEBROSUS, n. Sp. 



Black; antennae and tarsi reddish. Densely clothed 

 with muddy-brown and sooty scales. Prothorax with six very 

 feeble fascicles, elytra with many. 



Head rather strongly convex ; with very dense punctures, 

 concealed between eyes. Kostrum rather short, stout, and 

 strongly curved, sides distinctly incurved to middle, distinctly 

 notched on each side of base; with dense and coarse punc- 

 tures, becoming more regular, but still dense, in front of 

 antennae. Scape stout, inserted in middle of rostrum, about 

 half the length of funicle and club combined. Prothorax 

 rather strongly transverse, sides strongly rounded ; with dense 

 partially-concealed punctures; second to seventh interstices 

 with very feeble tubercular swellings, supporting feeble
