Mr. Howard described this species from 3 9 specimens dissected 

 from the supposed eggs of Dysdercus sttturellus, sent to Dr. Riley by 

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

 of Euiliociha galcator Fabr., Avith which 1 am quite familiar, from my 

 long residence in Florida.
