is reproduced. The median shade and submarginal and marginal 

 bands are absent. The exterior line is distinct, formed of brown 

 spots on the nervules. In the female the submarginal row of spots 

 is reproduced beneath, in the male it is absent or hardly perceptible. 

 On the posterior wings the exterior and interior lines are continued, 

 ochreous, with brown spots on the nervules. The submarginal spots 

 are also present, more evident in the female. Fringe as above.

This species is closely related to Fidonia bicoloraria Minot, from 

 which it can be distinguished by its smaller size (bicoloraria ex- 

 pands 27 mm.) The following additional distinctions exist between 

 the two species. In quadripunctata the discal dots are very large 

 and of equal size on all the wings, above and beneath; in bicol- 

 oraria the dots on the anterior wings are large, while on the pos- 

 terior wings they are small, faint, often nearly obsolete. On the an- 

 terior wings of quadripunctata beneath, the exterior and anterior lines 

 are present and very clearly marked ; in bicoloraria only the costal 

 portion of the exterior line is found, and that is sometimes absent. 

 In quadripunctata the posterior wings above have the lines and sub- 

 marginal spots more or less marked, the marginal band of the ante- 

 riors is also continued on the posteriors ; in bicoloraria the posterior 

 wings are only marked with the faint discal dot and with brown 

 atoms. In bicoloraria the fringe of the posterior wings is immaculate ; 

 in quadripunctata it is interrupted with brown. The habits of the 

 species are also different, bicoloraria I have found resting on the 

 trunks of trees, only flying when disturbed; while quadripunctata is 

 found with truncataria Walk, in dry, sterile, open fields, very difficult 

 to capture and flying actively at mid-day. 



One female, three male quadripunctata and six male, one female 

 bicoloraria examined.
