sni'face impunctate ; anterior and posterior angles rounded. Elytra 

 about as long as the prothorax, narrowed anteriorly, moderately 

 strongly and closely punctured. Abdomen rather finely punctured. 

 Length 6| mm. 



Lottah, Gould's Country, Tasmania (^Simson). 



A very distinct species differing from all the species known to 

 me in its uniform colour and strongly punctured head and pro- 

 thorax.

Mentum very short. Ligula small, entire, rounded in front. 

 Paraglossse large, acuminate. Maxillary palpi filiform, joints 2-4 

 nearly equal, the last slightly acuminate. Labial palpi filiform, 

 the joints gradually increasing in length, the terminal joint 

 acuminate. Maxillise with the internal lobe shorter than the 

 other, coriaceous, and ciliated internally; the external lobe corneous, 

 ciliated above. Mandibles very short, falciform, dentate in the 

 middle of the inner side, membranous and ciliate at the base. 

 Labrum corneous, transverse, bilobed, with the sides membranous. 

 Head more or less elongate, connected with the prothorax by a 

 rather narrow neck. Eyes small, rounded. Antennoe short, 

 strongly geniculate, rather robust, 1st joint moderately elongate, 

 the 2nd and 3rd obconical, joints 4-10 short, pubescent, the 

 terminal joint sub-acuminate at the extremity. Prothorax 

 elongate, often a little narrowed towards the base, which is 

 rounded ; the anterior angles usually a little produced. Elytra 

 truncate behind. Abdomen parallel-sided. Legs short ; the inter- 

 mediate coxae distant ; tibiae spined, the anterior pair a little 

 thickened ; tarsi simple, the first two joints nearly equal. 



This genus contains a large number of species from all parts of 

 the world, many of which are brightly coloured. They are found 

 in moss, decaying vegetable matter, and under bark.
