NOTE ON HEMIHYALEA AND SOME SPECIES OF AMASTUS 149 



Treated by Hampson as a subspecies of H. cornea Herrich-Schaffer 

 (Cat. Lep. Phal., iii, 131, 1 90 1 ) but quite distinct as Rothschild has 

 shown (Nov. Zool., xvi, 277, 1909). The discal area of fore wing is 

 generally more or less hyaJine, the bands quite distinct in good specimens. 

 The dark brown margins are cheiracteristic, the wing looking as if burnt 

 around the edge. 



Hemihyalea euomithia Dyar. 



To be more fully described in my fifth Mexican paper. It is distin- 

 guished from daraha by the brown, dentate, terminal border and the 

 much darker bands. 



Hemihyalea testacea Rothschild. 



Hemihyalea testacea Rothschild, Ann. Mag. Nat. Hist., (8), iv, 213, 1909. 

 Hemihyalea argillacea Rothschild, Nov. Zool., xvi, 277, 1910. 



A very distinct and uniform species, which I have only from Mexico. 

 H. argillacea was described from Gold Hill, Oregon ; but Rothschild 

 cites eilso specimens from GuatemcJa. From the description, I can make 

 nothing of argillacea but rubbed testacea and have so tentatively 

 refened it. 



Hemihyalea rhoda Druce. 



Phctgoptera rhoda Druce, Ann. Mag. Nat. Hist., (6), xiii, 173, 1894. 

 Hemihyalea fascescens Rothschild, Nov. Zool., xvi, 277, 1909. 



A brown species, the fore wing strongly subhyaline zmd irrorate, the 

 bands practically obsolete. The subspecies hidalgonis will be described 

 in my fifth Mexican paper. 



Hemihyalea mansueta H. Edwards. 



Halesidota mansueta H. Eldwards, Pap., iv, 75, 1884. 

 Hemihyalea battyi Rothschild, Nov. Zool., xvi, 278, 1909. 



A rather variable species. Fore wing generally opaquish dark ocher, 

 the outer margin narrowly burnt brown. When bands appear, they 

 consist of macular ocher yellow ones, surrounded by blackish dots. This 

 is about the commonest Mexican species and extends southward at least 

 as far as Colombieu 



Hemihyalea labecula Grote. 

 TTie well-known Coloradan species.
