430 REVISION OF THE AUSTRALIAN CURCULIONID.E, 



Head with rather coarse punctures; shallow!}^ depressed behind 

 eyes, which are large and subapproximate. Rostrum scarcely 

 the length of prothorax, sides feebly incurved to middle; distinctly 

 punctate throughout, but punctures much coarser on basal than 

 on apical half; with a feeble median ridge behind antennae. Scape 

 inserted two-fifths from apex of rostrum and shorter than funicle; 

 1st joint of funicle slightly longer than 2nd, 4th-7th transverse. 

 Prothorax moderately transverse, sides strongly rounded; with 

 dense round clearly-cut punctures; with a continuous median 

 carina, which, however, becomes rather feeble anteriorly. Elytra 

 scarcely wider than and not thrice the length of prothorax, with 

 series of large, round, regular punctures; interstices (except the 

 suture) narrower than punctures and regular throughout. Punc- 

 tures of metasternal episterna not continuous throughout; those of 

 3rd and 4th abdominal segments somewhat irregular at sides but 

 in only one row on each across middle. Femora acutely, the 

 four posterior strongly dentate. Length 9, rostrum 2; width 

 5 mm. 



Hah. — Q. : Cooktown (Mr. C. French). 



Very close to vetustus, but distinguished by the larger size and 

 the almost jet-black antennae. It appears also to be close to 

 lateralis^ but the elytral punctures and clothing do not agree with 

 Mr. Pascoe's description. The elytral fasciae, though very dis- 

 tinct, are not sharply defined except on the sides : the first com- 

 mences on the side at the basal third, but at the 4th interstice 

 divides into two, of which one part touches the scutellum, the 

 other the suture before the middle; the enclosed space is some- 

 what diamond-shaped, but contains a few pale scales; the posterior 

 fascia is at the apical fourth and scarcely touches the suture. 



Tyrt^osus cinerascens, n.sp. 



Black, elytra almost black, antennae dull red. Upper surface 

 (including head and base of rostrum) moderately densely clothed 

 with whitish scales intermingled with mouse- coloured ones, the 

 whole having a speckled appearance. Under surface and legs 

 with dense whitish scales.
