Pupa — Average length 1.50 inches. Cylindrical ; broadest at shoulders, the abdo- 

 men larofe, recurving ventrally toward anus, and terminating in a broad, flattened, 

 posteriorly rounded, transverse, sliirhtly decurving flap, the borders thickened basally 

 and extending ventrally so as to surround ttie bilobed anus. Eyes prominent, with a 

 transverse carina: wing-sheaths reaching hind part of 4th abdominal joint, ventrally • 

 hind tarsi to about the hind third of these, and the club of antennae— which torms a 

 prominent bulge but tapers to a point — nearly as far. Surface but slightly polished 

 and faintly corrugate ; a few extremely minute bristlt-like spines disfrinuted over the 

 abdominal joints, dorsally, and the two or three terminal joints with stiff rufous hairs, 

 increasing posteriorly and thickest on the flap. Chitinous covering delicate, and all 

 the members clearly defined. Prothoracic spiracle showing as an opaque, dull fulvous 

 elliptic ovoid wart. Color brown-black anteriorly, paler on the abdomen, and more or 

 less densely covered with a white powdery secretion like that which characterizes the 

 full-gnuvn larva. 



Imago. — Generic Characters — Head small, the width, including eyes, not much 

 more than half that of the mesothorax ; the antennal bulbus large, and the inter- 

 antennal space not wider than one of the sockets; covered with rather eveidy shorn 

 dense hairs, and flattened scales not overhanging the eyes. Eyes small and smooth! 

 No ocelli Labial palpi (Fig. 54, c) stout and short, not reaching to top of eyes. 3 jointed* 

 the basal joint broad but short, the middle joint 4 times as long, the terminal joint tu- 

 berculous and one-sixth as long as the preceding: clothed in short and thick hair-like 

 scales. Tongue filiform, rather more than one-half the antennal length. Antennaj 

 rigid, cjiindrical, terminating in an elongate knob (Fig. 54, d) which is slightly flattened 

 and slightly tapering and recurved at tip, but without apical spine ortutt: havino- 

 rather more (cf) or rather less (2) than half the costal length ol primaries, Thora% 

 very robust, recalling that of A'v^ew^es ; clothed with close-lying hair which becomes 

 longer and looser behind; the patagia rather broad, forming two crescent-shaped, 

 slightly raised layers ; the teguhc closely appressed. Legs (Fig. 54, e, f, g, front, mid- 

 dle and hind) with brushy hairs beneath the femora ; the tarsi all studded beneath with 

 minute reddish spines, the hind and middle tibioe still more strongly spined, and each 

 with a pair of more prominent spine-like, apical spurs of equal size, and hardly longer 

 thai the other spines in (j^ and not longer than the diameter of tibise in $ : the front 

 tibiao unarmed, the nodule on the inner apical third ovoid and dark : tarsal claws with 

 a very small pulvillus between them: tront femora 5.5 mm. long; tibia3 rather more 

 than half as long; tarsi as long as femora: middle femora 7.4 mm. long; tibia; and 

 tarsi but slightly shorter : hind femora same length as front ones ; tibiae one-filth lont^er. 

 [Fig. 54.] Wings, with the scales small but mostly long, 



narrow and dense, with long hair at base supe- 

 riorly and with the general shape and venatioa 

 (Fig. 54, a, b) of Hesperia, the primaries with 

 the apical angle more acute, but less so than in 

 Thymele ; anal angle not produced but rounded : 

 secondaries nai-row and more rounded than iu 

 any other Hesperid genus known to me: veins 

 quite stout. Abdomen $, very stout and heavy, 

 tnickening behind, blunt at tip, and truncate 

 below; cj^ more slender and gradually taper- 

 ing. Specific Characters. — Average expanse 

 2.50 inches; length ol body 1.12 inches. Gen- 

 eral C(dor, above, deep umber-brown, the body 

 more grayish, especially the tegulfe ; the longer 

 hairs of the me.-othorax and base ot abdomen 

 inclining to ferruginous : whitish in Ironr and 

 around the neck and back of the eyes. Prima- 

 ries with a notched ferruginous band on the 

 outer lourth bounded by veins 1 and 4 ; a nar- 

 rower mark running from the posterior margin 

 of this between 4 and (i; a paler mark in a line 

 with the first band between G and 9, and a ter- 

 ruguious mark again just within the discal area 

 — the veins traversing the .'-pots showing dis- 

 tinctly black: an apical shade, a cosial streak 

 between veins 8 and 9, and alternate marks ou 

 the Iriiiges, are pale yellowish ; while the basal 

 hairs are ferruginous. Secondaries with a fer- 

 ruginous border and straw-jellow fringes. In 

 the (^ the antennal stem is palei-, the spots on
