Discussion: F. cockerelli may be readily separated from the other 

 species of Friseria by the buff to dark brown color of the forewings and 

 by the lack of fasciae. F. caieta appears blue white and black, the 

 other species have a complete or partial oblique fascia at one- third 

 or one-fourth on the forewing. 



The various synonyms of cockerelli reflect the species variability 

 in maculation. Meyrick's sarcochlora is a pale form; the three Busck 

 names cover pale, medium, and dark forms. In a given locality all 

 gradations between nearly immaculate buff to dark brown specimens 

 are likely to occur. Neither the male nor female genitalia reflect the 

 maculational differences.

Figures 48, 111, 113, 124, 163, 231, 232 



Maculation: as in figure 48. Head: tongue white with a few 

 brown flecks; maxillary palpus white, a few apical scales tipped with 

 brown; first segment of labial palpus white with a dorsal brown 

 saddle, second segment white with an incomplete brown band near 

 base and a brown band on outer and anterior surfaces before apex, 

 third segment white with a brown ring at one-fourth and a brown 

 ring before apex; dorsal surface of scape of antenna brown wdth white 

 scales subbasally and at apex, ventral surface white; shaft mixed 

 brown and white or gray basally, becoming mainly bro^vn distally; 

 frons white; vertex and occiput white, some scales with brown apices. 

 Thorax: white, several scales on tegula and middle of mesothorax 

 dark brown tipped. Forewing: white, dark brown, and orange 

 brown, many brown scales with gray bases. Hindwing: fuscous, 

 cilia pale buff. Prothoracic leg: anterior surface of coxa mixed 

 white and brown, femur and tibia brown with some white scale 

 bases, apex of tibia and a fascia at base of epiphysis white; tarsus 

 brown, apices of first three segments white. Mesothoracic leg: 

 coxa and femur mainly white with some brown scales; tibia mainly
