oruba Schs.; veins 7-10 on primaries stalked and secondaries with veins 3 

 and 4 more or less stalked and vein 8 short. H. strigulosa vanes the 

 Brazilian specimens agreeing with the neuration of this group, but Mexi- 

 can specimens have vein 10 from the cell, thus connecting it with the 

 group of alsus Cr., atomaria Walk., pedinata Schs., catemdata Hubn 

 and laroipa Druce. 



Halisidota margona, sp. nov. 



Body chrome yellow, the patagia. inwardly shaded with brown. Primaries 

 acute with outer margin straight and oblique ; yellow, the inner margin dark brown ; 

 fine wavy brown lines cross the wings, very indistinct at the base; the outer and 

 submarginal lines double, filled in with a slightly darker shade than the ground color 

 and the submarginal line ceases at vein 5; a terminal row of darker spots edged 

 with brownish between the veins; a dark spot at the end of the cell. Secondaries 

 whitish yellow. Expanse, 52 mm. 



Habitat: Jalapa, Mexico. 



Allied to H. strigulosa Walk. 



Halisidota quanta, sp. nov. 



Head and thorax chrome yellow, the collar finely edged with brown. Abdomen 

 buff above, whitish underneath. Primaries chrome yellow with transverse darker 

 lunular shades and a broad dark gray streak from the base to just below the apex. 

 Secondaries white. Underneath yellowish white. Expanse, 38 mm. 



Habitat: Castro, Parana. 



Neuration agrees with Mexican specimens of H. strigulosa Walk. 



Halisidota rosetta, sp. nov. 



Head and collar dark buf^-; thorax paler. Abdomen pink above ; underneath 

 buff with three gray streaks. Primaries yellow with some indistinct fine lunular 

 streaks, especially towards the outer margin; a fine dark brown Ime along the 

 median nervure to vein 4; a short black streak between veins 5 and 6 ; a submar- 

 ginal row of minute dark spots. Secondaries white. Expanse, 43 mm. 



Habitat: Sao Paulo, S. E. Brazil. 



Neuration agrees with H. quanta Schs. 



Halisidota pectina, sp. nov. , , a . 



Antenna very deeply pectinated in the $. Head and thorax dark buft; two 

 black points on the collar and two on each patagia. Body chrome yellow Primaries 

 yellow with a broad basal and median transverse grayish shade; a double terminal 

 and subterminal fine dark wavy line, the space within filled with a darker shade; 

 the fringe yellowish with some black spots. Secondaries yellow. Expanse, $ 41 mm. 



Habitat: Jalapa, Mexico. 



Allied to what I have as alsus Cr., though I am doubtful about 

 the identification, having no Surinam specimens and Cramer's figure 

 being rather poor.
