408 REVISION OF THE AUSTRALIAN CURCULIONID^, VIII., 



than in the (J; the rostrum is longer, shining except at extreme 

 base, and the scape inserted at basal two-fifths. Length 12f, 

 rostrum 4 J; width 6 mm. 



Hab. — Q.: Endeavour River (Macleay Museum), Cooktown 

 (Mr. C. French). 



Each of the large scales of the under surface instead of being 

 placed in the middle of a puncture is placed at its base, so that 

 although the depth of the puncture is concealed its extent is 

 readily seen. 



Mecistocerus tenuirostris, n.sp. 



(J(?). Blackish-brown, antennae and claw-joints paler. Not 

 very densely clothed with rather pale ochreous-brown scales, 

 which are longer on prothorax than on the elytra; on the latter 

 they are moderately dense on the interstices, on the former they 

 are confined to the punctures; with small spots and blotches of 

 pale scales scattered about. Under surface rather sparsely 

 clothed, the clothing, except on sides of sterna, more or less setose 

 in character; femora feebly ringed. Basal third of rostrum 

 squamose. 



Head in places coarsely and densely punctate, the punctures 

 more or less concealed; ocular fovea deep, narrow and elongate, 

 being fully half the length of head. Rostrum long, thin and 

 moderately curved, considerably longer than prothorax; basal 

 two-fifths rather coarsely punctate and with three narrow ridges, 

 the median one of these being traceable to between the antennae 

 where it terminates in a very feeble elongate impression; else- 

 where shining and lightly punctate. Scape inserted very slightly 

 closer to apex than base of rostrum and slightly shorter than 

 funicle; of the latter the 2nd joint is thin, twice the length of 

 the 1st, and the length of the 3rd and 4th combined, the others 

 gradually decreasing in length but none transverse; club the 

 length of the four preceding joints. Prothorax with dense round 

 and rather shallow punctures, each of which contains but is 

 scarcely obscured by a scale; median carina entirely absent. 

 Elytra cordate, considerably wider than and more than twice the
