to the lateral line. Very obscure lines as before, waved, whitish. Thoracic feet black, except at 

 joints; abdominal ones all green, the claspers smoky. Spiracles reddish centered. Later there is. 

 a broken obscure snhstigmatal line, composed of oblique, pulverulent, yellowish dashes; the 

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

 sometimes with a median red mark on jt)int 13. 



"Fourth stage. — 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 oft'. Head liglit green, not shining; beliind 

 the black ocelli a dark reddish band extends to middle of side posteriorly, ending in a blackish 

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

 and ends on Joint o at tlie lateral line; ])alpi reddish; widtli, 1'..") mm. Eody smootli, green, with a 

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

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

 dots for the stigmatal line. Spiracles light reddish. TJie obliijue line on Joints 2-3 is yellow below 

 and smoky red above, and may be faintly repeated on Joint 4. Setie minute, dark. Feet green, 

 the thoracic ones marked with black on the Joints. 



"Fifth stage. — Head rounded, 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, t\idiug to yellowish on its lower side, continuous with the line on Joints 2-3. Body 

 soft, yellowish leaf-green, tapering posteriorly, 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 superstigmatally. Dorsum faintly 

 white shaded; subventral region clear, soft green. Thoracic feet reddish, black at tip. Set;e 

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



"The species is double-brooded at Flattsburg, N. Y., single-bi'ooded in the Adirondacks, 

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

Moth. — Three 3 . Ground color, especially of the thorax and fove 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. Antenuie very 

 slightly pectinated, as'in L. (tngulosa 



Fore wings more pointed at the apex than in L. aiif/tilo.tu, with an oblique dark line crossing 

 the wing from the basal third of the co.sta to the outer fourth of the inner edge, and inclosing a 

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

 short and broad tuft, which is not acute as in X. straguUi, but with the distal edge very broad, as 

 in L. angnlosa. 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 i\\^ hind wings, which are pale, though 

 somewliat dusky on the outer margin. No brown marginal and apical brown spots bke those 

 oi' N. stragul((, and the wing is not so clear, but dusted with brown scales. Underside pale 

 subocherous, witli a common diffuse scalloped line. 



Expanse of wings, S , ■40-4^ mm.; length of body, t5 , 19-20 mm.
