 rounded between R 3 and M 2 , the marginal area wider betweeu these veins, the 

 double line bordering this area more straight ; the discal band which touches 



the lower angle of cell narrower. On hindwing the upper portion of the white 



discal baud much nearer the margin, the blackish discal band very wide, being 

 abont twice as broad as in Brazilian pluto. 



Underside : almost uniformly brown, without prominent speckles of brown 

 and buff. Forewing with traces of three fuscons bauds in central half, uniting

Machaerosema nom. nov. 



Rhcscyntis Hubuer, Verx.-bek. Schmett. p. 157 (1822?) (partim). 



The type of Rhescyntis being armida Cram. (1779), a new name is necessary 

 for the genus composed of hippodamia Cram. (1777), martii Perty (1834), norax 

 Drnce (1879), and the new species described below. Name-type : hippodamia.
