250 REVISION OF THE AUSTRALIAN CURCULIONID.E, 



Genus Lyb.eba, Pascoe. 

 Ann. Mag. Nat. Hist. (4), xi., 1873, p. 186. 



Head small, not concealed by prothorax; ocular fovea small, 

 seldom traceable. Eyes ovate or subelliptic, not distant, rather 

 coarsely faceted. Rostrum long, thin, parallel-sided, or decreas- 

 ing from base to apex, especially in front of the antennae, curved, 

 continued beyond mesosternum. Antenna; slender ; scape the 

 length of or shorter than funicle, insertion variable; two basal 

 joints of funicle elongate; club of moderate size, joints distinct. 

 Prothorax con-\ex, subconical, apex feebly pi'oduced, much less 

 than the width of base, base strongly bisinuate; constriction feeble; 

 ocular lobes obtuse. Scut ell um usually slightly i-aised and longer 

 than wide. Elytra convex, subcordate, considerabl}- or not much 

 wider than prothorax, shoulders and apex rounded. Pectoral 

 canal wide in front of anterior coxae; these somewhat excavated 

 above and but feebly separated. Mesosternal plate strongly 

 transverse, feebly concave, emargination very feeble, base truncate. 

 Metasternum large, shorter than basal segment of abdomen ; 

 episterna large. Abdomen large, sutures distinct ; 1st segment 

 the length of three following combined, intercoxal process moder- 

 ately wide and rounded ; intermediates small, their combined 

 length slightly shorter than that of 2nd or 5th. Leys moderately 

 long ; femora stout, clavate, not grooved, strongly and acutely 

 dentate, the four anterior sometimes rather feebly dentate, 

 posterior extending to apex of abdomen or not; tibiae somewhat 

 rounded, straight or feebly bisinuate beneath, terminal hook very 

 small; tarsi stout, 3rd joint wide, deepl}' bilobed; claw-joint thin, 

 exsertion variable, claws feeble. Ovate, convex, squamose, punc- 

 tate, winged. 



Allied to Melanterius, but with the 2nd abdominal segment 

 smaller and the femora not grooved, and with a shorter and less 

 convex form. I do not believe that both Lybceha and Enide* 

 can be retained, and, acting in that belief, have united the species
