TETRASTICHUS GERSTAECKERIAE, new species 



Females of this species are distinguished with difficulty from those

 extending from between the bases of the antennae to the upper ex- 

 tremity of the depression and by having the apex of the forewing 

 evenly rounded and with a very short marginal fringe. In all the 24 

 specimens of maldcosomae available for examination the head is col-
