562 NOTES ON AUSTRALIAN COLEOPTERA, 



lateribus leviter arcuatis, angulis posticis sat elongatis 

 bicarinatis, leviter divai-icatis ; elytris fortiter punctulato- 

 striatis, leviter (apicem versus fortius) convexis subtilissime 

 punctulatis, apice suturali vix prominente ; tarsorum lamella 

 quam latiori multo longiori, apice aiigustata, prothoracis 

 margine laterali baud in prosternum subducto. 



[Long. 8, lat. 2 lines. 



A somewhat exceptional species through the shape of the lamella 

 on the tarsi which is very narrow and elongate and (instead of 

 being truncate at the apex) is narrower at the apex than in the 

 middle, the apical margin being rounded. The true lateral margin 

 of the prothorax (when surveyed from a point perpendicularly 

 above the middle of the base] is not hidden (close to the apex of 

 the hind angle) by the external keel. The puncturation of the 

 head is rather strong and a little rugulose ; on the prothorax the 

 puncturation in front is almost similar, but becomes gradually 

 finer towards the sides and base. From some points of view the 

 prothorax appears obsoletely keeled down the middle line.

Of this genus, — remarkable among the Elaterides for the great 

 length of the antennae of the male, and the shortness of those of 

 the female (which do not reach the base of the prothorax), as well 

 as for other exaggerated sexual differences,— two species were
