XI. On various Australian Longicorn Beetles. By W. 

 Wilson Saunders, Esq., F.L.S. 



[Read November 4th, 1850.] 



A great many interesting forms among the smaller Longicornes 

 having during the last few years been brought to this country 

 from our Australian colonies, I have thought that an account of 

 some of them would be interesting to entomologists ; particularly 

 if I combined with them figures and short descriptions of some 

 of the interesting, nearly allied forms which had only before been 

 described, but wanted good portraits to point out their structure. 

 The species now brought together form no particular family or 

 group, but will probably be divisible into several ; but their affi- 

 nities are not easy to mark out distinctly with our present know- 

 ledge of the subject, and I therefore leave this point for future 

 observers to determine. The whole of the Australian Longi- 

 cornes want careful revision ; and it is to be hoped that such an 

 interesting investigation will soon be taken up by some entomolo- 

 gist who has time and opportunity to work the subject out. 



FIRST DIVISION. 



WINGS NOT ABBREVIATED. 

 EYES ROUNDED OR OVATE. 



Enciioptera. New genus {eyy(OQ irrepov). 



Head produced into a long, declining, gradually tapering snout. 

 Antennae not so long as the body, filiform, 11 -jointed, geniculate, 

 with the 1st joint long and clavate; 2nd, short, rounded; 3rd to 

 1 1 th, long, subclavate, gradually decreasing in length. Eyes mode- 

 rate, ovate. Thorax elongate, cylindrical, with rounded obsolete 

 tubercles on the sides. Elytra tapering to a point, not so long as 

 abdomen, and gaping at the suture. Abdomen long, clavate. Legs 

 long and attenuated, with the femora clavate. 



This genus is nearly allied to Macrones of Newman, but differs 

 in the longer thorax, which is nearly smooth on the sides, and the 

 longer and pointed snout.
