Astyci (pars) Hiibner; Astyci Scudder, Pamphilinae Butler. 

 Mabille. 



What honey in the year's last flowers can hide 

 These little yellow butterflies may know; 

 With falling" leaves they waver to' and fro, 

 Or on the swinging tops of asters ride.

And when I wander here and there, 

 I then do most go right.

Imago. Generally of small size, relatively slender, .\ntennae with a somewhat 

 stout club, which usually tapers rapidly and has a slight hook or crook composed of 

 from one to a dozen joints, much shorter than the mass of the club, occasionally absent 

 and generally recurved at about a right angle. Co.stal margin of fore wings gen- 

 erally straighter than in Hesperidi, with no marginal fold, often furnished in the male 

 with a complicated and conspicuous discal patch of varied scales and androconia ; cell 

 of same wings less than two-thirds as long as the wings ; hind wings almost always 

 entire, sometimes roundly lobed at the extremity of the submedian nervule. Ab- 

 domen as long as, or surpassing the hind wings, the extremity of the alimentary canal 

 of the male not protected by any extruded sheath, but opening at the very base of the 

 inferior part of the centrum ; for the lateral .arms originate from the very extremity 

 of the inferior surface of the centrum or even beyond it, leaving an open space behind 

 into which the anal orifice opens. 



Egg. Very compact, almost hemispherical, the height much less than the diameter, 

 the sides rounded and sloping oH" above, furnished with scarcely perceptible raised or 

 indented liues dividing the whole surface into angular, pretty regular, minute cells; 

 with rare exceptions without reticulation and then with very obscure vertical carinae, 

 but with no connecting transverse lines. 



Caterpillar at birth. Last abdominal segment with many very long bristly hairs, 

 which are more or less strongly recurved. 



Mature caterpillar. Head narrowing above, giving the whole head as viewed from 

 in front a triangular or pyramidal aspect. Body very elongated, the abdominal seg- 

 ments usually divided by transverse creases into seven sections, adjoining pairs occa- 

 sionally connate. 



Chrysalis. Comparatively slender, nearly equal throughout its entire length, except- 

 ing the last two or three joints of the abdomen, the head scarcely, if at all, narrower 

 than the thorax, always protuberant in the middle in front, sometimes mucronate; 

 tongue case very loug, extending free to some distance beyond the tips of the wing 

 cases. 



Characteristics of the tribe. The fore wings of the males of this 

 most neglected but really very interesting tribe of butterflies are never 

 furnished with a costal fold, but, instead, are often supplied with an 

 oblique* dash of velvety appearance crossing the median nervules near the 

 middle of the wing, and which is composed of extremely short and fine, 

 most densely crowded, erect hairs and androconia. It is generally followed 

 externally by patches of raised scales, often colored differently from the sur- 

 rounding scales and is accompanied more intimately by loose, dark scales of 

 *In some Australian genera it is nearly transverse.
