outward in the median S])aee, and widely bordered witli a i)ale reddish tawny ])atch, the line not 



coiitinned to the inner (hinder) edge of tlie wiug. The middle (intradiscal) line very distinctly 



bent outward on the costal edge, maldng a large rectangle on the cubital vein, ending, after 



making a small tooth, on the distinct reddish brown tuft on the hinder edge of the wing. Within 



the costal portion of this line is a small white patch, and a very large white patch on the outside 



extending from tlie apex of tbe augle in tlie median sjtace to the cost;i. 



Extradiscal line wavy, forming about eight line teeth, reddish brown, edged externally with 



white, tlie line itself nearly straight, not wavy nor very obliipie (much less sinuous than in L. 



fcrnifiiiica), and on each side of the costal end the wing is more or 

 less marked with white. The space between these two lines does 

 not differ in shade from the ground color of the wing (while in L. 

 fernii/iiica the space forms a distinct broad reddish brown band). 

 A very faint submarginal diffuse line composed of very obscure 

 dark colored lunules. Fringe of the same hue as the wings, with 

 linear white marks at the end of the venules. 



lliiul wings and abdomen i)ale soft flesh-whitish, the costal 

 edge broadly margined with mouse color, interrupted by a trans- 

 verse broad. costal band, and another at the apex, not reaching 

 inward beyond the second subcostal veinilc. 



Eeneath, both wings uniformly whitish, the costal edge slightly 

 and irregularly clouded, but the lines not reproduced beneath. 

 Expanse of wings, 9 , 40-4.5 mm.; length of body, 9 , 17 mm. 

 Egg. — Hemispherical, rather higli, not flattened; the emjity shell chalky white, under a 



lens appearing to be very finely pitted; under .J-inch objective .seen to be ornamented with dense 



close set rounded granulations, with no space between them, and no polygonal areas: microjtyle 



apical, distinct. Diameter, 0.7 mm. The oiitice eaten by the larva is irregularly oval. 



Larva. — Somewhat like X^adata gihhosu, but ""he head is smaller, and it has no supraaual 



plate, and the body is smooth, not granulated. Head nearly as wide as the prothoracic segment, 



but not so wide as the body; full and rounded, though a little flattened 



above; deep pea-green, but concolorous with the body. On the side a 



pink line edged above with white extending to base of the antenna-. 



]\Iandibles green at base, with an orange-red line along upper edge. Tips 



black. A short black line above at base of antennse. Body noctuiform, 



tapering toward the anal legs, which are short and small, no larger tluui 



the other abdominal legs, sujiraanal plate small, rounded at the end, not 



large and corispicuous as in Nadata gihhosa. Segments not convex, but 



the sutures distinct. A faint double median, whitish, somewhat broken 



line, the two lines converging and forming a single one on the middle of 



the supraaual plate and tinged sliglitly with pink. A distinct lateral pink 



line begins on side of the head and extends to end of the body along 



the edge of supraaual plate. The line is somewhat finely brown, and is 



edged below with white. The whole body and legs pea-green, slightly 



darker below than alctng the back. Thoracic feet, greenish amber, sjiotted 



externally with black. Length, 0.40 mm. 



The following descrii)tion of the larval stages, pujia, etc., are copied 



from Mr. Dyar's paper in Proceedings of the Boston Society of Natural 



History, November, 1894: 



'■'■First larral stage. — The newly hatched larva is entirely .sinning yellow, d mm. long. Head 



cordate, as wide as high, pale brown, slightly shining; eyes black, mouth brown; width, 0.6 mm. 



Body slender, long, smooth, with minute black setae arising from inconspicuous black dots. Anal 



feet extended nearly backward, .slender, partly aborted. Color, leaf-green, shining, a yellow shade 



ijtigmatally. All the feet black, contrasting.
