1712 THE BUTTERFLIES OF KEW EKGLAND. 



joints as the remaimlcr of the antennae and almost invarial)ly a few more, is only 

 about two-thirds as long as it; the crook excluded, proportionally longer and slenderer 

 in the larger than in most of the smaller species, l)eing about fi)ur tinges as long 

 as broad, pretty stout, oval, increasing in size pretty gradually on the basal half and 

 at the extremity much more rapidly, l)luntly rounded in the smaller species; from Ave 

 to six times as long as broad, moderately slender and cylindrical, increasing in size very 

 gradually at the base, more broadly but less rapidly in the larger species than in the 

 others, in both largest about the middle of the apical half; the crook exhibits similar 

 tlifferences in the two sections, being composed in the smaller species of only five or 

 six joints and forming an appendage, tapering pretty rapidly, about twice as long as 

 broad and considerably shorter than the breadth of the club proper; while in the 

 larger liutterflies it is composed of seven joints and forms a long and slender, gradually 

 tapering appendage three or four times as long as broad and considoral)ly longer than 

 the breadth of the club ; middle joints of the stalk generally three times as long as 

 broad but in some of the largest species only twice as long as broad; the third from 

 the base rather less than four times as long as broad. Palpi rather short and very 

 stout, from one and a half to two times the diameter of the eye, heavily clothed 

 •with a mass of not very long scales, appressed on the apical half of the palpus, 

 beyond which about lialf of the terminal joint, heavily clothed with recumbent 

 scales, more or less distinctly protrudes; basal joint buUate, subpyriform, a lit- 

 tle appressed, as broad as or broader than long, with a tumid expansion inwardly at 

 the extremity; middle joint large, bullate, obovate, broadly and about equally rounded 

 at either extremity, generally a little largest at the distal extremity, nearly straight, 

 about as broad as the basal joint and about twice as long as broad ; terminal joint 

 seated on the middle of the extremity of the second joint, straight, sometimes cj'lin- 

 drical, very bluntly pointed at the extremity, at otliers largest just beyond the base 

 and tapering equally to a rather blunt point ; generally about three times as long as 

 broad but in the largest species, where it is nearest cylindrical, fully four times as long 

 as broad and as long as the breadth of the middle joint, while in tlie others its length 

 is but three-fourths the breadth of the middle joint. 



Prothoracic lobes rather small, appressed, laminate; when viewed from the front, 

 subtriangular, the inner and lower edges nearly straight and at right angles, the upper 

 outer edge strongly arcuate, a little bent in the middle, the whole piece varying in 

 height from half as long again as high, to scarcely longer than high, in all cases about 

 as long as the shorter diameter of the eye. Patagia pretty large, very nearly as long 

 as the breadth of the head, the posterior lobe half as broad and fully half as long 

 again as the base, in the smallest species equal, tapering only next the rather broadly 

 rounded tip, in the larger ones and those of medium size distinctly tapering through- 

 out, the tip bluntly rounded. 



Fore wing (42 : 18) twice as long as broad or scarcely less than that, the lower 

 outer angle falling slightly beyond the middle of the costal margiu, particularly in the 

 females ; the costal margin straight excepting for the slight apical deflection ; outer 

 margin regularly aud slightly convex. The costal nervure terminates a little beyond 

 the middle of the costal margin ; the subcostal is tolerably close to the costal margin, 

 its second nervule arising scarcely before the middle of the Ming; cell fully three- 

 fifths as long as the wing, rather slender, produced in the middle of the apical half 

 which is subequal. First submedian nervure arising considerably nearer the second 

 than the base of the wing, the second about opposite the second subcostal nervure ; 

 internal nervure short, straight. 



Hind W'ing slightly longer than broad, shaped almost exactly as iu Polites but more 

 uniformly rounded. Subcostal and median nervures first forking at equal distances 

 from the base at the middle of the basal two-thirds of the wing. 



Discal stigma of male very simple, consisting of two nearly equal, short, nearly 

 continuous, straight strigae in the lower two median interspaces, the upper one often 

 arcuate and sometimes the latter in a reverse sense, formed of dead black, sub-erect 

 or retrorse rods, with very slight peculiarities in the margination, the subjoined area
