111. Halisidota oslari s|iec. nov. 



S. Dill'ers from fr.s.sc/lur/.s Abbot & Smith by its much rounder forewing and 

 convex, not semiconcave, onter margin of forewing, absence of green margins to the 

 tegulae and patagia, and sooty grey, not bnff, tarsi. All the wings are uniform 

 creamy white, and the bands of forewings, which are distinct in tesselluris, are here 

 only indicated by the very faintest remains of the black hair-streaks that form the 

 margins of these bands in tessellaris. This form I consider a good species as 

 I received from (_)slar from the same localities typical tesfteUaris. 



? . Similar, but shows traces of green margins to jiatagia. 



Length of forewing : S 23 mm. ; ? 25 mm.

<i2. Halisidota interlineata iuteusa snbspec. nov. 



t_?. This is the western form of iiilcrliiii'((tii W'llc. Walker's type came from 

 Brazil, and 1 have specimens from the Eastern side of Mexico down to Rio Janeiro; 

 while my twenty-eight sjiecimeus of i uteri iiwatu ihti'iisa range from Western Costa 

 Rica, Merida, Venezuela, down to South Peru. 



It differs from interlineata interli ncatu by its much larger size, intense black 

 and orange of the costal and discocellular patches, and the more intense orange-bntf 

 ground colour. The postmeilian transverse band of forewing is always jiresent, 

 while in int. interlineata it is mostly entirely absent, but occasionally indicated in 

 Mexican examples by a single small spot. The green margins to tegulae and 

 patagia are very broad and intense in colour. 



?. Similar. 



Length of forewing : largest ////. interlineatn. S 25 mm.; ? 2s mm.
