DESCRIPTIONS OF TWO MOTHS FEOM FORMOSA. 

 By A. E. WiLEMAN, F.E.S. 



Spilosoma solitaria. 



J. Antennae bipectinatecl, black; head and thorax black, the 

 latter with an orange yellow dot in front and jet black lines above ; 

 abdomen orange yellow with seven black rings, the seventh twice as 

 wide as the others. Wings blackish, black markings as in the female. 

 •Underside fuliginous. 



Expanse 36 mm. 



The male specimen now described was received for identifica- 

 tion from Dr. Shiraki, of Taihoku, Formosa, labelled as follows : 



" Formosa, Kosbun, 1918, iv, 25-v, 25, J. Sonan, K. Miyake, 

 M. Yoshino." 



Although differing greatly in size and colour from the female, 

 it agrees exactly in markings of thorax and very closely with 

 those on the wings and abdomen. Unfortunately the wings are 

 •conhiderably abraded. The female was described as Diacrisia 

 solitaria in 1910 ('Entom.,' vol. xliii, p. 245). 



Gandaritis postalha, sp. n. 



J . Head and thorax yellowish mixed with purplish brown, abdo- 

 men greyish brown. Fore wings yellow, mottled with pale purplish 

 brown, basal area purplish brown ; antemedial line angled below costa 

 and indented before dorsum, discal mark blackish ; postmedial dark 

 purphsh, rather wavy, outwardly oblique to vein 4, thence inwardly 

 oblique to dorsum, subterminal line purplish brown, wavy, most 

 distinct towards costa ; a dark purplish line from apex of the wing 

 unites with the postmedial by a bar along vein 5 ; the enclosed space 

 is clearer yellow than rest of the wing ; terminal area below the line 

 from apex purplish, except at tornus ; fringes dark purplish brown. 

 Hindwings white, teru:iinal area yellow, inwardly bordered with 

 purplish ; fringes dark purplish. Underside similar to above, but 

 fore wings without purplish brown mottling. 



Expanse 62 mm. 



The male specimen described, which is not in very good con- 

 -dition, was received for identification from Dr. Sbiraki, of Taihoku, 

 Formosa, labelled as follows : 



" Horisha. 18 . v . viii, H. Kawamura."
