to the lateral line. N'oiy obscure lines as before, waved, wliitisli. Thoracic feet black, except at 

 joints; abdominal ones all green, theclaspers smoky. Spiracles reddish centered. T-ater there is- 

 a broken obscure substigniatal line, comi)()sed of obli(iue, ])ulverulent, yellowish dashes; the 

 stigmatal line forms undulations over the spiracles, and the addorsal line becomes broad, white, 

 sometimes with a median red mark on joint 13. 



'■'■Fourth stutje. — The larva rests on the petiole of a leaf and eats all but the midrib on which it 

 rests. When the leaf is consumed the stem is bitten off. Head light green, not shining; behind 

 the black ocelli a dark reddisli band extends to nuddle of side itosteriorly, ending in a blackish 

 shade and continuous with an oblique line on the body, which extends over the spiracle on joint 2 

 and ends on joint ■> at the lateral line; ])ali)i reddish; width, 2.5 mm. Body smooth, green, with a 

 broad, geminate, white dorsal band (addorsal lines), tilled in with dull red in some specimens; a 

 narrow waved subdorsal line; a row of white dots in i)lacc of the lateral line and a few yellow 

 dots for the stigmatal line. Spiracles light reddish. The obliciue line on joints 2-3 is yellow below 

 and smoky red above, and may be faintly repeated on joint -1. Seta^ minute, dark. Feet green, 

 the thoracic ones marked with black on the joints. 



'■'■Fifth stage. — Head rouiuled, broad, flattened before; light green; a white line on each side of 

 clypeus and another from palpi converging slightly to vertex of each lobe; lateral band smoky 

 purplish red, fading to yellowish on its lower side, continuous with the line on joints 2-3. Body 

 soft, yellowish leaf-green, tapering ]>osteriorly, full, plump, cylindrical. A broad, yellowish white- 

 geminate dorsal band, the space tilled in with reddish on joint 13; faint traces of a broken 

 subdorsal and two or three round yellow dots laterally and superstigniatally. Dorsum faintly 

 white shaded; subventral region clear, soft green. Thoracic feet reddish, bhu'k at tiji. Setie 

 extremely minute except on the legs. Claspers brownish. Length, about 30 mm. 



" The species is donble-brooded at Plattsburg, N. Y., single-brooded in the Adirondacks,. 

 though a single $ emerged the same season." (Dyar.)

Moth. — Three S . (iround color, esi)ecially of the thorax and fore wings, ash-gray. Head 

 and thorax ash-gray sprinkled with reddish brown scales; a distinct line extending across the 

 thorax between the fore wings. Palpi with a dark brown line on the outside. Antenna! very 

 slightly ]>ectinated, as'in L. minidosa 



I'oic wings moie jjointcd at the apex tlian in L. (oujuJom, with an ol)lique dark line crossing 

 the wing from the basal third of the costa to the outer fourth of the inner edge, and inclosing it 

 dark rusty brown patch which fades out on the costa, and is deepest in hue next to the large but 

 short iuid broad tuft, which is not acute as in ,V. strdf/ula, but with the distal edge veiy broad, as 

 in L. ((iH/idomi. Beyond the patch and tuft is a short sinuous or bent whitish line, the continuation 

 of a faint sinuous line extending from the costa, but which becomes much more distinct behind 

 the third cubital venule, ending on the inner edge of the wing, and continued on the costa of the 

 hind wings, thence extending as a scalloped line across the hind wings, which are pale, thougli 

 somewhat dusky on the outer margin. No brown marginal and apical brown spots like those- 

 of N. stnir/uln, and the wing is not so clear, but dusted with brown scales. Underside pale 

 suboeherous, with a common dift'iise scalloped line. 



Expanse of wings, <J , 40-4!) mm.; length of body, S , 19-20 mm.
