Mr. Howard described this species from 3 9 specimens dissected 

 from the supposed eggs of Dysdercus snturellusj sent to Dr. Eiley by 

 Mr. H. S. Williams, April 1, 1889. The eggs appear to me to be those 

 of Euthoctha galeator Fabr., with which I am quite familiar, from my 

 long residence in Florida.
