XXL Neiv Coleoptera from Australia and Tasmania, 

 in the Collection of the British Museum. By 

 Chas. O. Waterhouse. 



[Read July 3rd, 1878.] 



The British Museum Collection lias lately received some 

 additions from Tasmania, which have led me to examine 

 some groups of Lamellicorns and Heteromera with a view 

 to their determination. Some interesting new genera and 

 new species have thus been brought to light, of which 

 I here append descriptions. 



RUTELIDiE. 



Saulostomus, gen. nov. 



Mentum narrowed at the insertion of the palpi, with 

 the anterior margin truncate. Labrum with the margin 

 gently arcuate and not produced in the middle. Tarsi 

 rather short and robust, the first four joints subequal, 

 scarcely as long as broad, the first joint a little the longest. 

 Claws simple. Antennaj 10-jointed. Elytra with a mem- 

 branous border. 



Closely allied to Schizognathus, but without the mesial 

 production to the mentum and labrum. It differs from 

 Amblyterus in having short tarsi with simple claws. 

 Schizognathus and the other genera of BrachysternincR 

 have a mesial projection to the labrum, the absence, there- 

 fore, of this would seem to exclude the present insect from 

 this subfamily. There is, however, no other place for it, 

 and it must be regarded as a slightly aberrant form. The 

 presence of the membranous border to the elytra exclude 

 it from the true Rutelidce, and the 10-jointed antennse 

 from the Anomalinoe. 



Saulostomus villosus, sp. n. 



Piceus, nitidus, fulvo-pubescens ; corpore subtus pedi- 

 busque fiavo-testaceis ; thorace transverse, a^neo-tincto, 



TKANS. ENT. SOC. 1878. — PART III. (oCT.)
