424 REVISION OF THE AUSTRALIAN CURCULIONID^, VIII., 



but rounded, apex incurved; 2nd-4th drawn slightly backwards 

 at sides; 3rd and 4th combined the length of 5th and slightly 

 shorter than 2nd. Legs moderately long; femora sublinear, not 

 grooved, edentate, posterior not extending to apex of abdomen; 

 tibiae rather stout and almost straight, tarsi normal. Briefly 

 ovate, convex, squamose, winged. 



A distinct genus which might be regarded as allied to Chcttec- 

 tetorus, bub which is placed here on account of most of its 

 characters. From Cryptorhynchus it differs in the \'ery finely 

 faceted eyes, in the legs and basal segments of abdomen; Tituacia^ 

 to which on first sight it is rather close, differs in having coarsely 

 faceted eyes, elytra not much wider at the base than prothorax, 

 metasternum very short and the body apterous. 



Paratituacia dorsosignata, n.sp. 



Black or blackish-brown, antennae dull red, club darker. 

 Clothed with white scales feebly variegated with ochreous, and 

 with a very large and sharply defined patch of black scales com- 

 mencing at apex of prothorax and terminating beyond middle of 

 elytra. Under surface and legs with pure white scales. Head 

 (except at extreme base) and rostrum with black scales. 



Head with dense concealed punctures. Rostrum the length of 

 prothorax, sides incurved to middle; densely and rather coarsel}^ 

 punctate throughout and with a feeble median ridge on basal 

 half. Prothorax moderately transverse, sides rounded, apex less 

 than half the width of base; with dense, round, clearly cut but 

 concealt^d punctures. Elytra not much (but suddenly; wider 

 than prothorax, and about twice as long; with series of moder- 

 ately Inrge but almost entirely concealed punctures; interstices 

 wider than punctures, the 3id and 5th each with two very feeble 

 tubercular elevations. Under surface with dense concealed 

 punctures. Posterior femora not quite extending to middle of 

 apical segment. Length 3|, rostrum 1; width 2; variation in 

 length 3-3J mm.
