5. Penthema lisarda bowringi subsp. nov. (pi. XXI, fig. 5). 



8 2 . Allied to the race formosanum Koths. The fore wing 

 retains the basal stripe and the inner marginal stripe of the typical 

 form lisarda ; the median and submedian stripes are thicker and the 

 submarginal spots nearer the margin than in the Formosa form. Hind 

 wing with cell-patch as in light specimens of formosanum, but with 

 lower margin of cell more broadly brown. The stripe in cellule 3 

 well developed. Submarginal spots nearer the margin.

 August, two $ S , June, one $ , April, one $ , no date, one $ . 



The Formosa race appears to be a darker development of the 

 Hainan form, and most specimens from Formosa are very dark. The 

 form from Tonkin appears to be nearer formosanum than to bowringi. 



6. Cynthia, erota hainana Holl. 2 (pi. XXI, figs. 6-8). 



C. deione var. hainana Holland, Trans. Amer. Ent. Soc, xiv.,
