 contains an error in saying the genus Parhypates, Motschulsky, 

 is Australian ; this error has also been adopted by Mr. IMasters 

 in his Catalogue of the Coleoptera of Australia.*

(J Head very large (7 x 7 '5 mm.), convex, smooth ; front with a 

 strongly marked uneven wide impression on each side extending 

 on to the clypeus ; clypeal suture distinct between the frontal 

 impressions ; clypeus longitudinall}^ impressed in middle, lightly 

 emarginate behind labrum ; eyes convex, not prominent ; post- 

 ocular prominences large, almost equalling the eyes, not abruptly 

 declivous behind ; a prominent ridge extending forward from eyes 

 above base of antenna' ; genje greatly inflated below antenna?. 

 Mandibles long (aljout 6 mm.), decussating. Labrum subquadrate,

*I would also note that Homalo-wma hcncoUe, Brulle, and H. striaticoUe, 

 Brulle, though placed by Mr. Masters in his Australian list, are said by 

 . Brullt5 (Hist. Nat. Ins. iv. H64) to be from Madagascar. 



+ At the time of writing this description my single male specimen has 

 lost the anterior tarsi, but I had formerly observed and noted that they 

 were without squamulose tissue beneath — but ^Aithout noting their shape. 



J The length of the prothorax in the middle is 6 mm. ; the length from 

 anterior to basal angle is 7 mm.
