VIII. Length 14.0, head width 1.2126 mm. Head clear pale yellow; 

 cervical plate transparent with dusky cephalic margin; skin of thorax 

 pale yellow, of abdomen deeply covered with purplish-brown overcolor 

 against which the chocolate-brown pinacula are distinguishable only by 

 the texture of their surface. 



IX. Length 15.0, head width 1.4929 mm. Head yellow with a slight 

 brownish tinge and a very faint brownish pattern, clypeus whitish, rest 

 of mouth parts dark brown; ocellar area and marginal spot black; 

 cervical plate clear greenish-yellow with an oval fuscous spot near each 

 end; body color dusky green, darker caudad with the dense dark pur- 

 ple overcolor through which on the caudal two-thirds of the body there 

 are conspicuous rows of large clear vacuoles along the lateral and 

 segmental lines; skin granular, pinacula large, dark purple, shining and 

 feebly rugose; caudal plate dusky with dark points. For relative size 

 and arrangement of the pinacula see (Fig. II, 6.( 



The pupa. Length 9.0 mm., width 2.8 mm. Dusky yellow, of the 

 usual pyralid shape. Spiracles small but sharply elevated. Cremaster 

 broad, flattened, from above subquadrate, somewhat narrowed caudad 

 with a minute pale seta at each outward angle, the tip narrowed and 

 abruptly depressed, almost tubercle-like, bearing at its extremity a pair 

 of larger dark sets; lateral grooves shallower and narrower than in 

 most species, only moderately curved; beneath excavated. 



The adult. The following is Clemens' (1860) original description 

 slightly modified by Fernald (1896). (Fig. II, 1.) 



"Expanse of wings 23 mm. Head luteous ; thorax and palpi fuscous, 

 the latter whitish beneath. Fore wings ochreous, with two silvery- 

 white streaks separated by a fuscous streak; the outer silvery streak 

 margined on costa with fuscous; the inner one, which extends beyond 

 the apical third, edged on the fold with fuscous. Beneath the fold the 

 wing is pale yellowish with fuscous streaks along the submedian veins. 

 Apex of the wing tinted with ochreous yellow, the veins streaked with 

 silvery white; on the costa near the tip an oblique silvery streak, mar- 

 gined on both sides with fuscous. The subterminal silvery-white line 

 much angulated, bending in below the apex, leaving a large whitish 

 marginal patch streaked with dark parallel lines which end in dots 

 before the terminal line. Fringes lustrous ochreous. Hind wings pale 

 fuscous; fringes white." 



The Tennessee specimens agree well with this description but are 

 somewhat larger, averaging 27 mm. in alar expanse. The "whitish 

 marginal patch " is more pale fuscous than white and the "pale fuscous " 

 hind wings are whitish along the margins especially toward the apex. 



Genitalia. Female. (Fig. II, 2). Anal plate wider than long, 

 somewhat constricted at base, margins serrate with tubercles terminat- 

 ing in long stout spines ; the upper third sharply rounded and separated 

 from the rest by a deep rounded notch, lower lobe shorter than the 

 upper, evenly rounded above, slightly angled at lower corner. Alale. 

 Tegumen (PI. XII, Fig. 3) with both body and limbs rather narrow and 

 about equal in length the latter slightly narrowed mesad, and rounded
