Hyperiosoma falcatum, n.sp. 



Dark reddish-brown; antennse (club excepted) paler. Densely 

 clothed with soft muddy-brown scales, each elytron with a large 

 triangle of dingy whitish scales, its base on the sides and its apex 

 touching the 3rd interstice. Under surface, legs, head and 

 rostrum with paler scales than on pro thorax, and with rather 

 numerous whitish scales scattered about. 



Head with dense concealed punctures. Rostrum the length of 

 prothorax and almost parallel-sided; basal half with strong con- 

 cealed punctures; apical half shining and lightly punctate. Scape 

 inserted two-fifths from apex of rostrum ; 1st joint of funicle 

 stouter and slightly longer than 2nd, 7th longer than 6th. Fro- 

 thorax moderately transverse, convex, apex more than half the 

 width of base and scarcely produced; with dense, round, regular, 

 concealed punctures. Elytra about once and one-third the width 

 and twice and one-half the length of prothorax, sides parallel to 

 apical third; with series of large and round but almost entirely 

 concealed punctures. Under surface with dense concealed punc- 

 tures. Femora stout, teeth of anterior pair rather small, of inter- 

 mediate large and of posterior very large, posterior extending 

 almost to apex of abdomen; tibiae equally and rather strongly 

 curved and diminishing in width to apex. Length 5|, rostrum 

 1^; width 3 mm. 



Hah. — Q. : Cooktown (Herr J. Faust). 



The elytral triangles of pale scales are very distinct; the teeth 

 of the posterior femora are very large and triangular.

 moderate size, distant, coarsely faceted. Ghib ovate. Mesosternal 

 receptacle distinctly and rather suddenly raised, sides incurved to

 and not very stout; tibiae compressed and straight except at base. 

 Other characters as in the preceding genus.
