512 PROCEEDINGS OF THE NATIONAL MUSEUM vol. los 



Differing from distincta in having upper half of cell and interspaces 

 below cell orange and in having a submarginal series of orange spots 

 on the hindwing. 



Length of fore\\dng, 24-28 mm. (average, 26.6 mm.). 



Male genitalia as illustrated (figs. 39, 53). Aedeagus with dorsal 

 and ventral incisions much deeper than in distincta and forming two 

 lateral lobes that are not equal in size or shape. Five genitalia prepa- 

 rations were studied. 



Female: Plate 7, figure 25b. Head as in the male with outer sur- 

 faces of palpi pale yellow and scales behind eyes orange. Wings above 

 as illustrated with ground color yellow and nearly obliterated by the 

 dark brown markings along the veins. Submarginal spots large and 

 confluent with the vein markings. Wings below as in the male. 



Length of forewing, 26-28 mm. (average 27 mm.). 



Female genitalia as illustrated (fig. 92). The anterior lobe of the 

 inner genital plate is subtriangular, having the posterior margin ser- 

 ratulate and the ventral margin deeply undulate, forming five separate 

 lobelets. Ductus bursae lacks all sclerotization. Two genitalia 

 preparations were studied. 



Type locality: The original description specifies Venezuela and 

 Peru. According to Mr. Jean Bourgogne, of the Paris Museum, the 

 two original males are from Colombia and were purchased from a 

 Mr. Parzudaki. A lectot3^pe is not designated. 



Additional type data: Described from two males, co types (Co- 

 lombia, Mr. Parzudaki), and one female, presumed to be a cotype 

 (Peru, from Mr. Becker). 



Location of types: In the Museum National D'Historie Naturelle, 

 Paris. 



Method of identification: Identified by reference to the original 

 description, which fits no other species. Tatochila microdice arctodice 

 Staudinger and T. microdice macrodice Staudinger, the onl}^ other 

 species with which xanthodice could logically be confused, lack entirely 

 the submarginal streaks of orange between the veins on hindwings 

 below and never have black marginal lines on the hindwings above. 

 The present species is quite in agreement with the original description, 

 does have these orange streaks, and frequently has this black marginal 

 line. 



Synonymical notes: 



Tatochila -pTjrrhonniia Rober, 1908. Described from the male sex (number of 

 specimens not stated) from "Huancabamba," Department of Piura, Peru (3,000 

 m.). Type presumably in the Rober collection. The original description and 

 colored figure accompanying this name show clearly that it is a synonym of 

 xanthodice.
