side by a row of black ones. There is also a round black 

 spot at the end of the cell, which is sometimes visible above. 

 In the male, the black marginal bands of the upper surface are 

 incomplete and macular. 



GENUS SCIIATZIA. 



Eucheira (nee Dejean), Westwood, Trans. Ent. Soc. Lond. i. p. 

 44 (1834); Butler, Cist. Ent. i. pp. 34, 42 (1870); Schatz, 

 Exot. Schmett. ii. p. 62 (1886). 



Head and body very hairy, antennae with a gradually-formed 

 club ; wings with very long cells ; fore-wings triangular, 

 rounded off at the angles ; hind-wings oval, likewise much 

 rounded ; fore-wings with the sub-costal nervure four-branched, 

 the two first branches emitted before the end of the cell, the 

 third and fourth forming a long fork ; upper disco-cellular 

 nervule (rarely present in the Pieridcc) distinct, but short, so 

 that the first discoidal nervure rises from the cell, and not 

 beyond it. 



The type is a Mexican species, remarkable for the gregarious 

 nest-building habits of the larva ; a habit which is somewhat 

 uncommon in Butterflies, though more frequent in Moths. 



It is necessary to change the name of the genus, on account 

 of the Coleopterous genus Eiicheiriis^ Dejean, and I have there 

 fore been glad to name it after the late eminent Lepidopterist, 

 Dr. Schatz, whose work on the families and genera of Butter- 

 flies is one of the most valuable contributions to systematic 

 entomology that has ever appeared.
