smoky but paler anteriorly and terminally and fulvous along the 

 costa. Posterior wings translucent, nearly white in some lights, 

 roseate in others, dusky on anterior margin and on anterior half 

 of outer margin. Head, thorax, and abdomen, nearly uniform gray ; 

 thorax with a V-shaped black mark in front. 



Larva. — The larvse collected this autumn were dark, the general 

 effect being that of a nearly black insect with a broad buff band 

 below the stigmata, and a narrow yellow subdorsal line. The dor- 

 sum is black or a very dark brown with a yellow median line, and 

 irregular white lineations along the border of the dorsal space. The 

 subdorsal band is also black, slightly mottled along the lower margin, 

 bordered above by a yellow line which is itself bordered above and 

 below by a shade of deeper black. The stigmatal band is drab, 

 mottled with pale brown; the stigmata black, partly within the sub- 

 stigmatal band and partly within the subdorsal band. In one 

 specimen, the dorsum is pale chocolate brown with scarcely a 

 trace of the median line. The heads in all are jet black ex- 

 cept on the sides, behind the eyes, where they are somewhat 

 mottled with whitish. The Y-shaped mark upon the front is white 

 and deeply impressed. The cervical shield is black, with the median 

 line and subdorsal yellow lines continued upon it. Upon the caudal 

 shield the median line widens to a more or less triangular blotch. 

 The labrum is brown, the basal joint of the antenm? is wholly 

 white, the second joint white with a black ring at the base, and the 

 third joint brown. The venter is greenish brown beneath the buff 

 lateral band, becoming nearly yellow towards the bases of the pro- 

 legs. Each of the latter has a glossy black patch upon its outer 

 surface. Between these legs the surface is a brownish green. :* The 

 whole ventral area is finely mottled with yellow.* 



DISTRIBUTION. 



By Guenee, this species is reported to occur in North and South 

 America, and likewise to have been received by him from Tasmania. 



*The following is the description of the larva and pupa of this species given by Mr. 

 Riley, on page 117 of his Third Report as State Entomologist of Missouri: 



iacna.- Ground color very variable, generally dark and pitchy black when young, but 

 varying after the last moult from pale brown to pale dirty green, with more or less pink 

 or yellow admixed— all the markings produced by fine, more or less intense, brown, crim- 

 son, and yellow moitlings. Dorsum brownish with a narrow line down the middle, ren- 

 dered conspicuous by a darker shade each side of it. A dark, subdorsal band one-third 

 as wide as each joint is long; darkest at its upper edge, where it is bordered and dis- 

 tinctly separated from dorsum by a yellow line which, except on joint II, where it deflects 

 a little upwards, is quite straight; paler in the middle of each joint. A pale, either buff or 

 flesh colored substigmatal band, bordered above and below by a narrow, yellow and 

 wavy line. Venter pale. Head pale yellowish brown, with sometimes a tinge of green or 

 pink; the triangular piece yellowish, the Y-mark distinct and white, the cheeks with four 

 more or less distinct lateral brown lines and with dark brown mottlings and nettings, 

 which become confluent and form a dark curved mark at the submargin behind the 

 prongs and each side of the stem of the Y. Stigmata large, brown, with a pale annula- 

 tion, and just within the lower edge of the dark subdorsal band. Legs eithnr light or 

 dark. Cervical shield darker than body with the narrow dorsal and subdorsal lines ex- 

 tending conspicuously through it; anal plate also dark, narrow and margined by the pale 

 subdorsal lines-both plates furnishing stiff hairs, but without tubercles. Piliferous 

 tubercles on joints 2 and 3, arranged in a transverse row. and quite large, especially on 

 joint 2; on joints 4-10 the superior eight are arranged as follows: 4 in a trapezoid in dor- 

 sal space, the posterior two as far again from each other as the anterior two, and two 

 near the stigmata, one above and one behind; on joint 11 the dorsal 4 are in a square, and 

 on joint 12 in a trapezoid, with the posterior and not the anterior ones nearest together; 

 the thoracic joints have each a large subventral tubercle just above the legs. Length 

 1.10-1 .50 inch. Described from numerous specimens. 



P;(ija.— Formed in the ground, without cocoon; of normal form, bright mahogauy- 

 brown, and with a distinct forked point at extremity.
