Unfortunately, in making my drawings of this species and before I 

 had drawn up my description, I knocke<l ofl" the head of the male with 

 my pocket lens; it fell to the floor and could not be found. It is now 

 in too poor a condition for description, but I hope it will be recognized 

 by the figure.
