 considerably wider.

It was my intention to have used the abandoned 

 term of Rizophilus applied by Dr. Leach to Deme- 

 trias ; as it might lead to further confusion I merely 

 transpose the word, adopting that of Philorhizus, 

 from (^lXos- and pi£a. The species of the follow- 

 ing genera are apterous; as the types are well 

 known, there is no need of long generic characters, 

 the following may suffice. 



Philorhizus, Hope. 

 Apterous, form oblong. Thorax, with its ante- 

 rior part wider than the posterior. The anterior 

 angles are rounded, while the latter are nearly 

 rectangular. The elytra at the apex are not so 

 abruptly truncated as in Dromius, and are gradually 

 rounded from the external sides till they meet the 

 suture.
