Prothorax not overhanging head, subtriaugular, disc slightly- 

 convex, apical fourth narrow, subtubular; densely and rather 

 obsoletely punctate, numerous small granules on middle and 

 apical portions of disc, base without granules. SciUellum round, 

 raised, sloping downwards to prothorax. Elyt'^a slightly wider 

 than prothorax and not twice its length; base trisinuate, imping- 

 ing on prothorax on each side of suture; shoulders slightly- 

 projecting forwards; ten rows of punctures on each elytron, 

 punctures set in grooves, round, subapproximate, larger near 

 base (especially near shoulders) than elsewhere; interstices 

 usually wider than seriate punctures, finely punctate, rounded, 

 the alternate ones slightly raised; suture more distinctly raised 

 near scutellum than elsewhere, with small depressed granules; 

 apex with a thin mucro. Anterior legs long; femoral teeth more 

 noticeable than on four posterior; tibiae thin, arcuate, strongly^ 

 compressed; subapical tooth distinct (on four posterior they are 

 not visible); posterior femora just passing 3rd abdominal segment. 

 Length 8^, rostrum 2; width 4; range of variation 5^-12 mm. 



9. Differs in having rostrum thinner, longer, base densely but 

 not coarsely punctate, half the distance behind base rather 

 sparsely punctate; apical half highly polished and scarcely punc- 

 tate; scape thinner, insertion slightly nearer base than apex; 

 prothorax broader; elytral interstices scarcely alternately raised, 

 legs shorter, and apical mucro shorter. 



Rah. — Eastern Australia(widely distributed). Also recorded 

 -from Lord Howe and Norfolk Islands, and New Guinea. I have 

 obtained larvae and imagines which were boring in citrous trees 

 and various species of C asuarina. 



This species is subject to very great variation in size, colour 

 and density of scales, form, and sculpture. I have received 

 specimens from the late Herr J. Faust under various MS. names. 

 He sent me also a specimen labelled E. hrevispinis Fairm. The 

 male from which the above description was taken is rather 

 small, but in good condition. The white scales on the upper 

 surface of many specimens become yellow; the two small spots 

 on prothorax are frequently absent; the scutellar lobe is usually
