Hnb. — New South Wales (type in Macleay Museum). 



The shape is somewhat as in the preceding species, but the 

 clothing is very different (although the fascicles are almost in the 

 same positions), the femora are edentate and the rostrum is much 

 shorter. Although Mr. Pascoe in describing the genus notes the 

 femora as edentate, this is the only species here described in 

 which such is the case.

The species described below certainly belongs to the genus 

 Sybidus, now first recorded from Australia, but as Mr. Pascoe 

 states that at least six species of the genus occur in the Malay 

 Archipelago, and he describes the femora as being uni- or bi- 

 dentate, I have not thought it advisable to give a generic 

 diagnosis based on but one Australian species. The chief generic 

 features of this species, however, are its large and coarsely faceted 

 eyes, long and thin rostrum, longish subcylindrical club, the 

 sutures of which are oblique, U-shaped and slightly cavernous 

 mesosternal receptacle and distinctly bidentate femora. There 

 appears to be no closely allied genus in Australia; Mr. Pascoe 

 regarded it as being allied to Fezichus, but. its connection with 

 that genus is decidedly remote. 



Sybulus Yorkensis, n.sp. 



Black, antennae of a rather light red, club darker. Rather 

 densel}^ clothed with scales varying from white to dingy black, 

 but the majority of a rather dark fawn, scales larger and more 

 rounded on prothorax than on elytra. Under surface moderately 

 clothed with whitish scales; legs densely clothed with dingy scales. 

 Head and base of rostrum with feebly variegated scales. 



Head with dense concealed punctures. Rostrum longer tlian 

 prothorax, rather strongly curved, thin and feebly decreasing in 

 width from base; basal fifth strongly punctate, elsewhere highly 

 polished and impunctate. Scape inserted nearer base than apex 

 of rostrum and shorter than funicle; two basal joints of funicle
