EUPHYDRYAS SCUDDER. 



Eupliydryas Scudd., Syst. rev. Amer. butt., Melitaea (pars) Auctorum. 

 27 (1872). Type.—Papilio phaeton Dninj. 



Straight from the filth of this iow grub, behold ! 

 Comes fluttering forth a gaudy spendthrift heir, 

 All glossy gay, enamel'd all with gold. 

 The silly tenant of the summer air. 



Thomson. 



Imago (54 :5). Head moderately large, clothed, not very thickly, with rather short 

 hairs, longer about the antennae. Front slightly tumid, scarcely flattened at the cen- 

 tral portion, very slightly protuberant below, the whole projecting a little beyond the 

 front of the eyes, somewhat broader than long, about three-quarters the breadth of 

 the eyes; upper border descending rather rapidly in front of the antennae; lower bor- 

 der very abrupt and scarcely rounded. Vertex not very large, considerably tumid, 

 projecting considerably above tlie level of the eyes behind, nearly twice as broad as 

 long, the posterior border broadly rounded, the anterior descending roundly to the 

 antennal pits. Eyes modei'ately large and full, naked. Antennae inserted with their 

 posterior border in the middle of the summit, in distinct, very deep and large pits, sep- 

 arated by a space nearly equal to the diameter of the second antennal joint ; consider- 

 ably longer than the abdomen, composed of thirty or thirty-one joints of which ten 

 or eleven form the club, Avhich is naked, pretty strongly depressed, increases quite 

 gradually in size until, Avith the third or fourth joint from the tip, it begins again to 

 diminish in size, the extremity being broadly and rapidly rounded; the increment 

 in size is mostly on the outer side, and the club is about three times as broad as the 

 stalk and less than four times as long as broad, without carinations beneath; the 

 joints, both of the club and of the apical half of the stem, are rather prominent at 

 their tips, especially on the outer side. Palpi not long and moderately stout, about 

 half as long again as the eye, directed upward and a little forward, the last joint 

 scarcely more than one-third as long as the penultimate, but sparingly clothed with 

 the dense fringe of coarse hairs and scales which cover the upper and under surface 

 of the other joints, and which are much shorter here than there; near the tip of the 

 upper surface of the middle joint a number of long scale-like hairs are directed up- 

 ward, encircling the eye; all the longer clothing lies in a vertical plane. 



Prothoracic lobes moderate in size, strongly appressed, tapering transversely 

 toward either end, the ends well rounded and nearly equal, the upper surface broadly 

 rounded, about three times broader than high. Patagia nearly flat, moderately broad 

 and quite short, scarcely half as long again as broad, the basal portion somewhat 

 circular, the posterior lobe being a pointed, straight, rapidly tapering projection of 

 the hinder part, terminating in a bluntly pointed tip. 



Fore wings (39 : 1) scarcely twice as long as broad, the costal margin almost straight, 

 the apex rounded off; outer margin very broadly and regularly rounded ( $ ), the upper 

 two-thirds broadly and regularly rounded, the lower portion discontinuous and 

 straight {$), the general direction being at about 40° with the middle of the costal 

 margin ; inner margin straight, angle rounded ofl". First superior subcostal nervule 

 arising shortly before the apex of the cell ; the second at about the same distance 

 beyond the tip of the cell {$) or at the apex itself ( ?) ; the third half {$) or a lit- 

 tle more than half ( 9 ) way from the apex of the cell to the outer border ; second 

 inferior subcostal nervtile arising two-fifths way down the cell ; the latter considera- 

 bly less than half the length of the wing and three and a half times longer than 

 broad; last median nervnle connected, at a short distance from its base, with the vein 

 closing the cell. 



Hind wings with the costal margin pretty strongly and roundly shouldered at the 

 base, beyond straight, the outer angle broadly rounded; outer margin strongly
