94 Descriptions of ActinoptcryM australis. 



widest at the middle, with the sides much rounded and 

 slightly margined, marked ^vith rather large and distinct 

 punctures, the interstices smooth and shining, and also 

 with a broad shallow longitudinal depression on each side 

 near the middle of the disc, basal margin nearly straight 

 with its angles acute, but very little produced. 



SciUellum small, triangular, moderately asperate. 



Elytra a little longer than the head and thorax united, 

 suboval, slightly attenuated posteriorly, with the sides 

 slightly rounded and margined, moderately asperate in 

 very close wavy rows, marked with a broad longitudinal 

 depression on each side of the suture near the middle, apex 

 very little rounded, paler, with the extreme edge white. 



Ahdomm considerably exserted, attenuated towards the 

 apex. 



Legs long and slender, pale yellow with the femora 

 dusky. 



Beneath pitchy-castaneous with mouth coxte and apex of 

 the abdomen paler. 



Differs from A. fucicola in the shape, sculpture, and 

 very short posterior angles of the thorax. 



Habitat, Australia. 



Obs. — This species, as well as many others of the 

 Triclio^ytcryyia, is covered with a silvery epidermis, which, 

 when entire, completely conceals the superficial sculpture ; 

 l)ut the form of the thorax will always readily distinguish 

 it from A. fucicola.
