NO. 3546 MOTHS OF GENUS EUSCEPTIS TODD 11 



This species, the type of the genus, is also the smallest species of 

 the genus. It agrees with E. koehleri, new species, and differs from 

 the other similarly marked species in that the outer dark costal mark 

 of the forewing is about equal in width to the medial costal mark. 

 E. irretita Hiibner differs from koehleri by its slightly smaller size, 

 by the absence of a loop in the outer costal mark of the forcAving 

 immediately above the lower angle of the cell, by the orange terminal 

 line of the forewing not being curved around the apex of the wing, 

 and by the characteristic male genitaha (fig. 19). The valvae of the 

 male genitalia are simple, without spines or processes developed from 

 or immediately beyond the sacculus. Length of the forewing: male, 

 9 to 10 mm. 



Types: The present location of the type of irretita is unknown. 

 It may be in the Naturhistorisches Museum, Vienna, Austria. 

 Hiibner's type was from Brazil. The type of melanogramma was 

 from "Provincia Bahiensi," Brazil. It may be in the collection of 

 the Zoologische Sammlung des Bayerischen Staates, Munich, 

 Germany. At least part of Perty's types were received by that 

 institution. 



Distribution: E. irretita apparently is restricted to Brazil, possibly 

 to the northeastern part of that country. Only four males have been 

 examined. One is unlabeled, the other three are from Bahia and 

 Pernambuco, Brazil. 



Kemarks: The illustration of Perty's melanogramma appears to 

 be of a female. At least the marginal band of the hindwing is exten- 

 sive and similar to that of the female of the related koehleri. 



Method of determination: The species was identified from the 

 excellent illustrations accompanying the original description. Perty's 

 melanogramma was recognized as a synonym by means of the good 

 illustration in his work.
