Genus Cystineura 



Genus CYSTINEURA, Boisduval 



" And here and yonder a flaky butterfly 

 Was doubting in the air." 



McDoNALD. 



Butterfly. Small butterflies, with elongated fore wings, the 

 hind wings with the outer margin rounded, slightly crenulate. 

 The head is small; the palpi are very delicate and 

 thin, scantily clothed with scales. The costal 

 vein of the fore wing is much swollen near the 

 base. The subcostal vein of this wing sends 

 forth two branches before the end of the cell. 

 The upper discocellular vein is lacking; the mid- 

 dle discocellular is short and bent inwardly; the 

 lower discocellular is almost obliterated, and 

 reaches the median vein at the origin of the second 

 median nervule. In the hind wing the cell is open, 

 and the two radial veins spring from the same point. p, G I02 Neu- 



Early Stages. Very little is as yet definitely ration of the genus 

 ascertained as to these. 



But one species is found within the limits covered by this work. 

 Seven species have been described, all of them inhabiting Central 

 or South America. 



(i) Cystineura amymone, Menetries, Plate XXIV, Fig. 

 7, $ (Amymone). 



Butterfly. The fore wings are white on the upper side, 

 dusted with gray at the base, on the costa, the apex, and the 

 outer margin. The hind wings are gray on the basal area, pale 

 yellowish-brown on the limbal area, with a narrow fuscous mar- 

 gin. On the under side the markings of the upper side reappear, 

 the gray tints being replaced by yellow. The hind wings are 

 yellowish, with a white transverse band near the base and an in- 

 complete series of white spots on the limbal area. Expanse, 

 1.50 inch. 



The early stages await description. The insect is found 

 about Brownsville, Texas, and throughout Mexico and Central 

 America.
