Hyakotis. 

 Hyarotis, Moore, Lep. Cey. i. p. 174 (1881). Type adrastus, Cr. 



This is a monotypic genus established by Moore for Tlesperia adrastus, Cr., an insect 

 sufficiently distinguished by its facies. Vein 5 of the fore wing is straight throughout.

ISOTBINON. 



Isoteinon, ¥e\Aer, Wien. ent. Monats. vi. p. 30 (1862) ; Watson, P. Z. S. 1893, p. 83. Type 

 lamprospilus, Feld. 



Watson restricts the name Isoteinon to the lamprospilus of Felder and diagnoses the 

 genus by the direction of the third joint of the palpi, which is " erect, reaching well 

 above the vertex of the head, slender, obtusely conical." We have not seen any 

 specimens of lamprospilus, Feld., with palpi of this kind; for us, the third joint of the 

 palpus is short, about equal in length to one-fourth of the diameter of the eye, erecto- 

 patent, and not reaching to the level of the vertex ; and this condition does not appear 

 to be due to deflexion of tiie head in setting. The basal portion of vein 5 of the 

 fore wing recedes from vein 6.
