16 MR. K. Y. WATSOIT OK THE HESPBEIID.!. [Jan. 17, 



Little is known of the habits of this section, and, of those of which 

 there is any record, some seem to rest with their wings over their 

 backs, and some with them extended flat. 



This section is confined ahnost entirely to the New World ; only 

 seven of the genera occur in the Old World, and these are only 

 represented by one or two species each. 



The male is usually provided with a costal fold on the fore wing 

 and never with a discal stigma, occasionally with a tuft on one of 

 the wings, and very frequently with a tuft of long hairs attached to 

 the hind tibiae, which are usually, but not invariably, furnished 

 with two pairs of spurs. The epiphysis on the fore tibiae is invari- 

 ably present. 



Section B. 



Antennte seldom hooked, occasionally bluntly pointed. Palpi, 

 third joint either miiiute or porrected in front of the face, in the 

 latter case stout, and not slender as in the Entheus group in Section 

 A ; palpi never curving over the vertex. 



Fore wing : cell less than two-thirds the length of costa ; vein .5 

 invariably nearer to 6 than to 4. Hind wing frequently lobate, but 

 never with a distinct tail or tooth at the submedian ; vein 5 never 

 fully developed. 



This section can be readily separated by the position of vein .5 of 

 the fore wing together with the short cell. 



All the species of this group of which there is any record (with 

 the exception of a few species of Hesjieria) rest with their wings 

 extended flat when in a state of complete repose, frequently settling 

 on the underside of a leaf. 



This section occurs throughout both the New and the Old Worlds, 

 some of the genera having a very wide range. Most of the New- 

 World forms and a few of the Old-World ones are provided in the 

 male with a costal fold on the fore wing, and never with a discal 

 stigma. A very large number of the genera are also provided in 

 the male with a tuft of long hairs attached to the hind tibiae or fore 

 coxae. There arc invariably two pairs of spurs on the hind tibiae, 

 and the epiphysis of the fore tibiae is invariably present, with the 

 doubtful exception of some individuals of Abantis tettensis.

Section A. 



a. Hind tibiae with two pairs of spurs (except iu larsoctcnus * .ind 

 Casyapa *). 

 a}. Third joint of palpi minute, bluntly conical. 

 d-. Hind wing conspicuously tailed at vein 1 b. 



a^. Male with a tuft of hairs on underside of fore wing. 



PoLYTHRix, g. u. Type, mctallcscenn, Mab. (1) 

 P. No tuft of hairs on underside of fore wing in male. 



EuDAMus, Swains. Type, protcus, Linn. (2) 



* The form of the antennjE alone will readily distinguish these two genera 

 from the remaining genera in this section which have only one pair of spurs on 

 the hind tibire.
