The eastern inductata Guenee is likewise wrongly placed and should 

 go with this species. Eggs were obtained and the larvae carried to 

 stage iv, but here they hibernated and could not be induced to develop 

 the last stage. By October 10 they had all died. 



Egg. — Elliptical, compressed but rounded, no depression, tapering 

 to the micropylar end, which is small, truncate. Laid on the large 

 blunt end like butterfly eggs. Vertically ribbed, about nine ribs on 

 the broad side, low, rounded, finely waved 3^et distinct; cross stritB 

 slight, not waved, forming rectangular cells; upper end coarsely 

 rounded reticulate; all minutely granular shagreened. Pale yellow, 

 spotted with pale pink; size, 1 b}" 0.6 by 0.5 mm. 



Stage I. — Head round, slightly bilobed, pale brown, ocelli black. 

 Body very slender, elongate, the segments numerously finely annulate. 

 Pale whitish with subdorsal and subventral parallel, rather broad dark- 

 brown stripes, the subdorsal pair rather remote anteriorl}^, diluted by 

 the luteous cervical shield, approximate behind but separated by a 

 linear pale streak to the anal plate; subventral band more smoky and 

 pale. Foot of joint 13 brown lined; tubercles small; set^ short with 

 enlarged ends. 



Stage II. — Head bilobed, free, pale wdiitish with a baud of spots 

 over the lobes, eyes and antennge black marked; width, 0.5 mm. Body 

 long, slender, curled in twisted S-shape, finely annulate. Dorsum 

 broadly brown with a central geminate dorsal line; subventer pale 

 green broadh' on the fold below a l)road pale olivaceous band. Feet 

 pale; tubercles small, round, pale with black hair dots and short black 

 truncate setse. 



Stage III. — Head round, whitish, dotted with brown over the ver- 

 tex except in a central streak on the lobe; width, 0.7 mm. Body 

 slender, finely annulate, brown dorsally, a whitish dorsal line darker 

 edged, a darker edge above thel)road, greenish-white stigmatal stripe. 

 Subventer very dark; a ventral white stripe. Cervical shield pale 

 like the head; abdominal feet whitish without, dark brown before. 



Stage IV. — Head rounded, slightly bilobed, white below, yellowish 

 on the vertex, thickly dotted with pile brown except a streak on each 

 lobe; width, 1mm. Body slender, uniform, cylindrical, finelj^ annu- 

 late. Pale brown dorsally, subventral fold pale yellow, venter dark 

 brown, the colors shaded. A narrow addorsal blackish dotted line, a 

 series of dark-brown spots, two to each segment, joined b}' an obscure 

 dark subdorsal shade, a lighter medioventral line. Abdominal feet 

 light without; tubercles small; seta? short, thick, brown; no shields. 



The larvffi ate alder and Polygonum. 



EOIS ROTUNDOPENNATA Packard. 



Seven specimens, June 9, 16, 25, 29, and three from Mr. Cockles 

 collection, June 17 and 20, 1902. The specimens agree well w^ith 

 Packard's description of two males from Brunswick, Maine, except
