This widely distributed s]iecies somewhat resembles F. eiirynoine, but is of 

 smaller size and more finely juuu'tured. The head is shorter and less produced 

 in front; the basal margin is more angulated in the middle, so that the posterior 

 angles of the eyes are farther from the margin. The facial impression of the 

 male is less distinct and there ai-e only ten or eleven palal pegs. 



During life the head is l)ent down rather more than is shown in the figure, 

 and seen from above appears much wider than its length ; the eyes are wine red.
