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 varies, 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., pectinata Schs., catenulata Hubn 
and laroipa Druce. 
Halisidota margona, sp. nov. 
Body chrome yellow, the patagioe 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 buff; 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 line 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. 
Antennse very deeply pectinated in the g. Head and thorax dark buff; 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, g 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.
