strongly transverse, basal two-thirds almost parallel-sided ; 

 punctures normally concealed; with a feeble median carina. 

 Elytra with sides feebly and irregularly dilated to apical 

 third, then strongly and irregularly narrowed to apex, base 

 trisinuate; with irregular rows of large partially-concealed 

 punctures; suture with a conjoint tubercle halfway down 

 posterior declivity; each elytron produced at apex, and each 

 with a strong and rather wide curved ridge, commencing at 

 the second interstice at about the middle and terminated at 

 the side, where it is suddenly narrowed. Mesosternal 

 receptacle strongly elevated. Metasternal episterna narrow, 

 but frontal triangle large and distinct. Basal segm.ent of 

 ahdomen moderately convex, its suture with second rather 

 feeble and curved in middle, but deep at sides. Femora 

 stout, very feebly dentate. Length, 4-4;^ mm. 



Hah. — Victorian Alps (Blackburn's collection). Type, 

 I. 1458. 



The femoral dentition is extremely feeble and is quite 

 concealed from most directions. The elytra are much as in 

 cariosus, but the prothorax is very different. The conspicuous 

 slightly curved ridges at the summit of the posterior declivity 

 should prevent it from being confused with any other species. 

 One of the types (they are probably both females) is rather 

 badly abraded, but the other is evidently in good condition. 

 The latter has the clothing of the under-surface moderately 

 variegated, on the elytra its posterior declivity is mostly 

 clothed with sooty scales; on its prothorax there is a some- 

 what dingy patch of pale scales across the middle and feebly 

 connected with the middle of the base. 



EXITHIUS AUCHMERESTHES, U. Sp. 



Black; antennae and tarsi reddish. Densely clothed 

 with scales varying from a dingy-fawn or brown to sooty. 

 Prothorax with six fascicles, elytra with more. 



Read with normally-concealed punctures ; forehead tri- 

 sinuate. Rostrum moderately stout, sides lightly incurved to 

 middle ; with dense and coarse punctures, partially concealed 

 about base. Scape inserted in middle of rostrum, the length 

 of three following joints combined. Prothorax moderately 

 transverse, sides moderately rounded; punctures normally 

 concealed. Elytra rather elongate, sides feebly rounded, base 

 trisinuate, shoulders prominent; with rows of large partially- 

 concealed punctures ; each with three rather large fasciculated 

 tubercles in line with suture, fifth and seventh interstices 

 with some smaller ones; suture with a few granules near 

 base. Mesosternal receptacle strongly elevated. Metasternal 

 episterna very narrow. Femora stout, edentate. Length,, 

 4 mm.
