 August : it is uncommoidy abundant, since there are often from 

 thirty to forty larv;e on one plant."

Head smooth. Anteiuia^ setaceous, tlu^ hasal joint elongate, clavatc. 

 ].al)ial i)alpi of moderate length, curved, the second joint compressed, 

 the third joint shorter, acute. Tongue of moderate lengtli, clothed 

 with scales. Wings with very long cilia, the anterior nnicoloroits, me- 

 tallic, narrow, the posterior linear-lanceolate. In the anterior wings 

 the furcate apical vein runs out al)ove and below the apex, below it are 

 two veins ; the discoidal cell is dilated posteriorly, the subdorsal vein 

 is furcate, but the lower branch of the fork is al)breviatcd, the sub- 

 mediau is not thickened ; in the posterior wings the median vein has 

 three obsolete branches, the discoidal and apical veins are simple. 



Of the four species I have placed in this genus, the lirst two 

 only really belong here, the other two showing several discre- 

 pancies; I was unwilling to nudtiply the genera here to so great 

 an extcid as the formation of separate genera for niraldla and
