* Obs. — Several species of the genus Philonthus are now found in very 

 various and widely separated parts of the world. P. anens and P. sordidus 

 are notable instances of this. It is an interesting and important enquiry as 

 to how far the climatic and thermal circumstances vary in these different 

 localities, but I am not aware that any investigations have yet been made 

 on these points. — D. S.
