The describer, to avoid having a mixed-type series, restricted the 
type materials to the specimens reared from larvae feeding in 
Pluchea foetida and included besides the holotype male and allotype 
70 paratypes, all from Florida localities. There are many other 
specimens in the collection. 
Type, U.S.N.M. No. 54402.
