676 REVISION OF THE AUSTRALIAN CURCULIONID.E, 



sutures, 1st segment as long as 2nd and 3rd combined, 2nd dis- 

 tinctly longer than 5tli and slightly shorter than 3rd and 4th 

 combined. Legs moderately long; femora feebly grooved and 

 dentate, posterior not extending to apex of abdomen ; tibi?e 

 lightly compressed and almost straight, with a distinct subapical 

 tooth in addition to the terminal hook; tarsi normal. Oblong- 

 elliptic, convex, winged. 



Rather close to the preceding genus but differing in the eyes, 

 sterna, abdomen and legs; from Mecistocerus (to several species of 

 which the species described below bears a resemblance) it maj' be 

 distinguished by the sterna; and from Cryptorhynchus h\ the 

 comparatively large second abdominal segment. The sinuated 

 forehead would appear to denote affinity with a number of the 

 allies of Poropterus. The species described below is possibly 

 Boheman's Cryptorliynchus moestus, but the elytra of that species 

 are described as trisinuate at the base, with the interstices sub- 

 convex and only the posterior femora dentate. It is true that the 

 teeth of the four anterior femora of the specimens now described 

 are very indistinct and might easily be overlooked, but the elytra 

 are decidedly bisinuate at the base, with distinctly raised and 

 narrow interstices. 



The genus is apparently close to Cyamoholus (numerously repre- 

 sented in the Malay Archipelago and New Guinea), but differs 

 in the rostrum and rounded shoulders. 



NOTOCRYPTORHYNCHUS SINUATUS, n.sp. 



Black, antenme dull reddish-brown. Sparsely clothed with 

 elongate subsetose reddish-ochreous scales, but the elytra in addi- 

 tion with narrow transverse fasciae (almost or quite invisible to 

 the naked eye except posteriorly) of stramineous scales. Sterna 

 and legs with elongate pale scales, four apical segments with 

 stout muddy brown scales not rising above general level. 



HeoA feebl}'' punctate at base, elsewhere distinctly but irregu- 

 larly punctate; forehead irregularl}^ quadrisinuate; ocular fovea 

 rather large, a feeble ridge extending backwards from its posterior 

 end. Rostrum the length of prothorax; basal half coarsely punc-
