THE AMERICAN SPECIES OF DYSODIA 



{Lepidoptera, Thyridida) 

 By HARRISON G. DYAR 



In reviewing the genus Dysodia Clemens in 1897, Sir George F. 

 Hampson recognized but three species as American (Proc. Zool. Soc. 

 Lond., p. 609). Some others have been since described, but a number 

 of appaurently undescribed forms remain before me. The species may be 

 separated by the following table : 



Fore wing with white-hyaline discal spot. 



Subterminal band of fore wing broad or shaded; hind wing below with 

 round pale mottlings on a dark ground. 

 Ground color yellow ; hind wing below with few large pale mottlings. 



oculatana Clement 

 Ground color rosy brown, on fore wing entirely covered by black- 

 brown except for reticulated submarginal band . vitrina Boisduval 

 Ground color copf)ery orange; hind wing below with many small 

 pale mottlings. 

 Subterminal band present, especially on fore wing beneath; pale 



mottlings on hind wing below in lines, rather sparse summargo Dyar 

 Subtermmal band absent on fore wing below ; pale mottlings of 

 hind wing below very numerous and dense. 

 Wings below lilac brown .... immargo Dyar 



Wings below light straw color . . granulata Neumoegen 

 Subterminal band of fore wing narrow, linear. 



Yellow, overlaid with gray ; white discal spot of fore wing before the 



outer band monava Dyar 



Orange, coarsely irrorate ; white discal spot enclosed by the outer band. 



iguaUmis Dyar 

 Fore wing without a white-hyaline discal spot. 



Discal spot of hind wing, if present, whitish, subhyaline.
