REVISION OF THE AUSTRALIAN CURCULIONID.E 

 BELONGING TO THE SUBFAMILY CRYPTORHYN- 

 C HIDES. Part XII. 



By Arthur M. Lea, F.E.S. 



This Part deals with the balance of the genera allied to Porop- 

 terus. A large number of them have the base of the head more or 

 less strongly depressed, and with two to five emarginations (some- 

 times of considerable depth) on the forehead, a peculiarity that, with 

 few exceptions, appears to be confined to the group. In conse- 

 quence of the lateral emarginations, the eyes often appear as if 

 they were not embedded in the head ; usually when this is the case, 

 they are bent over on top. When the forehead is strongly sinuous, 

 the base is often bald and shining, and the tarsi are usually narrow 

 and shining. In those in which it is simply depressed at the base, 

 the central portion is often densely squamose, and rather strongly 

 convex, whilst the base itself is coarsely punctured and opaque, 

 but not squamose ; though in some species it is shining. But to see 

 these parts clearly, the head must usually be removed from the 

 body. 



The rostrum is usually the length of the prothorax; it is never 

 straight, but seldom strongly curved; it has always a more or less 

 shallow groove on each side above the scrobe. The eyes are usually 

 small, ovate, and coarsely faceted. 



The metasternum is always (except in Eufaustia) shorter than 

 the basal segment of abdomen, and is usually much shorter. Its 

 episterna are always narrow, and sometimes the median portion is 

 entirely concealed. In Scolyphrus, they are almost, whilst in Hop- 

 lodecilaus they are entirely without a triangular inner projection, 

 In some genera, they are entirely absent, or at least not traceable; 

 in a few only, the triangular projection is the only part left. This, 

 in Myrtesis and Cedilaus, is of an unusual size. 



In many, the suture between the first and second abdominal seg- 

 ments is soldered together, and curved across middle, although
