This species is of the size and general appearance of the common 

 M. quadrisignata Walk. I have named it sectomaculata in allusion 

 to its most distinctive character, the brown subterminal blotches, cut 

 by the nervules and exterior white line. 



Genus Fidonia. 



Fidonia quadripunctata (sp. nov.). 



Expanse, 21-22 mm. Length of body, 8 mm. 



Palpi brown above, white beneath. Front, vertex and thorax 

 clothed with intermixed white and brown scales. Abdomen, above 

 and below, whitish with numerous brown atoms. Legs whitish, with 

 tarsi alternated white and brown. Antennse in the male pectinated, 

 female simple. Ground color of the wings, pearl white. Anterior 

 wings, with brown atoms (in addition to the brown bands) on the 

 basal and costal regions. Interior line arcuated, dark brown, slightly 

 irregular, situated in, and partially concealed by, an ill-defined band, 

 composed of accumulated lighter brown atoms. Median shade, an 

 irregular brown band touching the interior line in the centre, and 

 separated from it on the costa and inner margin; faint yellow shades 

 sometimes present along its course. Discal dot black, large, situated 

 in the white median space. Exterior line very dark brown, slightly 

 dentate, undulating, subparallel to the outer margin, followed and 

 almost concealed by a broad, regular, brown, submarginal band; an- 

 other marginal band, equally broad, separated from the first by a 

 narrow band of the ground color. This band is narrow and regular 

 in the male, broader and irregular in the female, and in the latter its 

 central portion is occupied by a series of irregular dark brown spots. 

 Nervules slightly tinged with ochreous. An interrupted dark line at 

 the base of the fringe. Fringe dark brown interrupted with whitish 

 yellow between the nervules. Posterior wings above white, with nu- 

 merous brown atoms. Discal dot black, large. In the female the 

 interior and exterior lines are present, ochreous, subparallel, distinct, 

 with brown spots along their course; the submarginal dark brown 

 spots are also continued on the posteriors. The brown marginal 

 border is continued on the posteriors, but becomes obsolete before the 

 anal angle. A brown line at the base of the fringe, which is white 

 interrupted with brown. Wings beneath white, with numerous 

 brown atoms. Nervules ochreous. Discal dots large, very distinct, 

 equal in size on both wings. On the anterior wings the interior line
