1550 THE BUTTERFLIES OF \EW ENGLAND. 



Table of the genera of Pamplnlicli, based on the imago. 



Club of antennae not drawn out at the tip nor recurved. 



Terminal joint of palpi lightly clothed and free from the clothing of the second joint, ex- 

 ceptionally slender aud long, porrect; fore tibial epiphysis present; hind tibiae with two 



pairs of spurs Ancyloxlpha. 



Terminal joint of palpi heavily clothed aud much obscured by the clothing of the second 

 joint, pretty long but not exceptionally slender, advanced; fore tibial epiphysi-s absent; 



hind tibiae with only one pair of spurs Paniphila. 



Club of antennae with a distinct, though sometimes slight, recurved apical crook. 



Third joint of palpi long and slender; apex of fore wings bluntly angled, not produced; 

 cell of fore wings only three-flfths the length of the wing; fore wing of male usually pro- 

 vided with a stigma; upper half of hind wings longer than lower half. 

 Crook of anteunal club short aud rapidly tapering, scarcely longer than the width of the 

 moderately stout club ; costal margin of fore wings scarcely concave in ajiical 



half Amblyscirtes. 



Crook of anteunal club long and gradually tapering, fully twice as long as the width of 

 the slender club; costal margin of fore wings scarcely convex in apical half. 

 .Second joint of palpi short oval, not more than half as long again as broad; club 



of antennae, .apart from the crook, decidedly arcuate Poaues. 



Second joint of palpi long oval, fully twice as long as broad; club of antennae, 



apart from the crook, straight Ph ycanassa. 



Third joint of palpi generally short; apex of fore wing more or less pointed; cell of fore 



wing (excl. Lerema) more, often much more, than three-fifths the length of the wing ; no 



stigma on fore wing of male; lower half of hind wings as long as, or longer than, the 



upper half. 



Hind tarsi shorter than, though sometimes nearly equal in length to, the middle tarsi. 



Prevailing colors of the upper surface of the wings tawny. 



Hook of autennal club as long as the width of the club ; male with no discal stigma 



on the fore wing Atrytone. 



Hook of autennal club shorter than, generally much shorter than, the width of the 

 club; male with a discal stigma on the fore wings. 



Antennae hardly longer than the width of the thorax Hylephila. 



Antennae twice as long as the width of the thorax. 

 Cell of fore wings two-thirds as long as the wing. 



Club of antenuiie only moderately stout ; fore tarsi nearly five-sixths 

 as long as the middle tarsi ; stigma of male fore wing followed 



beneath by a conspicuous field of elevated scales Atalopedes. 



Club of antennae very stout and plump; fore tarsi only two-thirds as 

 long as the middle tarsi ; stigma of male fore wing with no conspicu- 

 ous inferior field Erynnis. 



Cell of fore wings only about three-fifths as long as the wing. 



Larger forms. Basal joint of palpi greatly expanded apically ; middle 

 and hind tibi.ae conspicuously spined on the upper surface, as else- 

 where; outer margin of hind wings scarcely lobed at suljmedian 



nervure Anthomaster. 



Smaller forms. Basal joint of palpi not apically expanded; middle 

 aud hind tibiae with no conspicuous spines on upper surface; outer 



margin of hind wings with no sign of a lobe Polites. 



Hind tarsi (excl. Lerema accius) longer than the middle tarsi. Prevailing colors of the 



wings brown. 



Anteunal crook moderately stout, hardly longer than the width of the rather short 



and stout club ; last joint of palpi slender. 



Cell of fore wing only three-fifths the length of the wing; discal stigma of fore 



wing of male discontinuous, and followed beneath more or less conspicuously 



by a substigmatic .area of special scales Thynielicus. 



Cell of fore wing nearly two-thirds as long as the wing; discal stigma of fore 

 wing of male continuous, and followed beneath by no substigm.atic area of 

 special scales Limochores.
