vestijration, and it is possible that insects from very remote regions 

 may be mingled in the refuse strainings in varnish factories, from the 

 melting; of gums and rosins from remote parts of the world. 



Mr. E. T. Cresson presented the following table of characters as an 

 aid in the separation of our species, thus far known, of the genus
