 spots, all of equal size, are placed at the tip of the second longi- 

 tudinal vein, at the base of the fork of the third longitudinal and 

 at the tip of the veinlets dividing the second, third, and fourth 

 posterior cells; on the upper corner (adjoining the base of the 

 discal cell) of the lower basal cell a small bluish opalescent spot ;
