PAMPIIILIDI: TIIK GENUS ERYNNIS. 1635 



whole antenna of Uic length or nciiHy of tlio Ictigtli of the abaonicn, composed of 

 from tliirty-tliree to thirty-live joints, of wliich sixteen to eighteen form the club, 

 which is nearly half as long as the stalk, the crook consisting of from four to six 

 minute joints; the latter tapers rapidly to a point and is but a little if any longer than 

 half the greatest width of the club; this is stout, oval, a little compressed, largest in 

 the middle of the outer three-llftlis, or at about the tenth joint from the tip of the 

 antennae, broadly rounded toward the crook, tapering gradually toward the base • 

 middle joints of the stalk .about three times longer than l)roail ; third joint scarcely 

 more than four times as long as broad. Palpi short and stout, about lialf as Ion" 

 again as the diameter of the eye, clothed very compactly with a mass of pretty long, 

 slender scales, which the apical joint, clotheil only with recumbent scales, scarcely 

 surpasses; basal joint small, buUate, triquetral, largest at apex, where it is protuber- 

 autat the inner interior extremity, and to a less degree externally ; middle joint large, 

 buUate, regular, oblong oval, scarcely arcuate, broadly rounded at either extremity, 

 but especially at the base, as long as the diameter of the eye, and about two and one- 

 half times longer than bro.id ; terminal joint minute, slender, equal, but l)luntly 

 pointed, straight, more than four times as long as broad, but scarcely longer tliau half 

 the breadth of the middle joint. 



Trothoracic lobes not very large, appressed Laminate, oval, more than Irnlf as long 

 again as high, more pointed at the exterior than the interior extremity, the length 

 about three-fourths the diameter of the eye. Patagia moderately large, the posterior 

 lobe not nearly half so broad as the base, fully as long, sometimes considerably longer 

 than the base, equal, tapering very gently throughout, the apex rounded, the whole 

 considerably shorter than the width of the head. 



Fore wing (42:1,10) almost twice as long as broad, the lower outer angle falling 

 scarcely beyond the middle of the costal margin ; costal margin scarcely concave in 

 the middle or slightly before It; outer margin gently and regularly convex, the apex 

 distinctly produced, sometimes more distinctly in the m.ale than in the female. Costal 

 nervure terminating a little beyond the middle of the costal margin; subcostal nervure 

 closely approximated to the costal margin, the second nervule arising at or scarcely 

 beyond the middle of the wing; cell two-thirds as long as the wing, very slender, sub- 

 equal in the apical three-fifths; first median nervule arising midway between the base 

 and the second, the second at or scarcely beyond the middle of the wing; internal 

 nervure straight, obscurely connected apically with the submedian. 



Hind wing a very little longer than broad ; the cost.al margin straight beyond the 

 strong basal lobe; the outer margin variable but always well rounded, sometimes with 

 a slight excision at the lower median nervule, so as to give a scarcely lobed appear- 

 ance to the outer border below this, but always about equally prominent in the subcos- 

 tal and submedian areas ; the anal angle well rounded. The subcostal nervure forks 

 before the median to a greater or less degree, the first median forking being tolerably 

 regular, at no great distance from the second, which is at the centre of the wing. 



Discal stigma of male (45:1) consisting of a gently arcuate streak, broadest 

 basally, pointed apically, crossing the base of the median interspaces and composed of 

 closely compacted, erect, dull black scales or rods, the lower edge supported and the 

 middle more or less longitudinally interrupted by a thin row of large and broad, erect 

 scales. The scales themselves consist of jointed threads in the heart of the stigma, in 

 the first section consisting of short, fusiform joints, in the second of equal and slen- 

 derer joints; these are accompanied by spatulate rods in some instances, and guarded 

 at the edges by two-pronged and three-pronged rods and elongated scales. 



Legs 2, 3, 1. Under surface of femora and upper surface of tibiae clothed as in 

 Euthymus. Femora 2, 1, 3; tibiae, 2, 3, I, or 2, 3, 1, in the latter case the middle 

 scarcely longer than the hind pair; tarsi 3, 2, 1, in tlie species which have the com- 

 paratively shorter middle tibiae approximately 3, 2, 1, so that the diflerencc in the 

 length of the middle and hind tibiae and tarsi together is more noticeable; fore 

 femora scarcely longer than the hind, fully four-fifths the length of the middle pair. 

 Fore tibiae two-thirds tlie length of the fore femora, three-fifths the length of the
