The larva lias been much confused.
It is appar-
ently this one referred to by Packard as Tferridaria in Moil. Geom., p. 494, Rept. U. S, dept. agric., 1886, p. 329, and 5th Kept. U. S. ent. comm., 13. 186. In the lat- ter publication the description of 7: endropiaria on p. 187 is of this species, Riley's specimen being befc& me. I have referred to these descriptions previously (PSYCHE, vol. 9, II, 1900), but have made there an error in regard to the food plant of T.fmidwIa (lines 6 to 8, second column) ; it is really spruce as Packard gives it. The life history of T.fisceUwia, here given, was obtained from moths kindly sent by Mr. H. S, Williams of Rockledge, Florida, in May. The first larvae
were matured in August and the moths appeared again in September. EGG.
Elliptical, the narrow diameter onlyslightly flattened in a. small area on the mid- dle of the side;
truncation forming a decided rim, but elevated centrally; depressed end rounded, ?11inost like the other end.
Surface smooth, except for very fine, rounciedly hexago- nal, moderately distinct reticulations, all over it, becoming a little larger at the antemici-opy- lar end.
The minute pores ill the angles show whitish in the shadow. Olivaceous green,
shining, turning dull reddish.
Size .9 X .6 X .5 iniii. Hatched in two weeks. STAGE I.
Head rounded bilobed, erect, free, rather large, month pointed ; dull dark brown, darker in the sutures, lighter on the faces of the lobes, eyes black; width .3 inn]. Body cylindrical. normal, moderately elongated, feet noi-uial slender, the abdominal ones
rather long ; segments slightly enlarged centrally. Grayish white, a shaded dark gray broad dorsal band, ni~rroweil in the incis~ires and absent at the ends. A subgeminate. darker, narrower and more distinct subdors~il band, fi~intcr at the cids but continuous, narrowed and confluent in the incisures. A similar subventral band. geminate, but seginentarily, macu- In all cases I retain the original spelling of genera, Eucoila, not Ewocfa., Acothyrms not Aconfstkyyens etc.

lately joined. A series of large, segmentary, ventral, cloiuied spots on the legless segments. Feel all pale; no shields ; setae short, stiff, white; tubercles imperceptible. Segments obscurely, rather numerously annulate.
STAGE 11. Head rounded. lobes large, full, but not bulging before, a little wider than high; white. a faint gray shade over vertex; luberc-les dark as also sutures of clypeus and ocelli; width .j mm. Eody moderate, normal, whitish with a bark gray tint ; dorsal space broadlj pale, containing black tubercles i and ii, bordered by a double black lateral band bro- ken into dashes. A more continuous and grayer subventral hand. Feet and venter pale,
tubercles dark, setae short, pale. Segments finely, faintly annnlate. No shields. The marks get fainter with growth, the general appearance being light, whitish gray. STACK 111. Head rounded bilubcd, moderate, white, very faintlygrayisli reticulate, small black dots on tubercles and at apex of clypeus ; width .9 mm. Body segments finely irregu-
larly annulate, grayish white, the dorsal line more translucent ; black dots on tubercles i and traces of the fonner lines as rather remote dots and streaks laterally and suprastigmatally. not forming well traceable lines. Snbdorsal and subventral bands rather whiter than the gen- eral color.
Feet all pale ; setae obscure; tubercles black marked. STAGE IV.
Head the same, the face a little more black dotted, quite thickly so in the vertical suture; width 1.3 mm.
Sides of body faintly grayish between the broken black lines, indicating a broad lateral shade. Dorsal space white, centered with a luteous line. Tubercles black.
STAGE V.
Head rounded, low bilohed, thick; white, Inteons freckled, blackish in inci- sure with distinct black dots on the tubercles; ocelli black; width 1.9 mm. Body rather
slender, moderately elongate; nearly white, tlic ground color pale luteous with straight white subdorsal line and wav irregular one in dorsal space, narrowly and obsrurely black edged; a waved snprastigmaLa1 line, black edged; an irregular white band on subventral fold not distinctly edged and a broad snbventra.1 bmd, straight like the subdorsal, black and bruwn edged. Tubercles small black ; feet pale; spiracles black ; general appearance very light bark gray, the lines not contra&Led mitli the ground color. STAGE VI.
Head rounded, hilobcd, narrowed a little above, lubes full before. Fleshy white, faintly mottled with light brownish ; tubercles marked by distinct round black dots; width 3.3 mm. Body normal, moderate, smooth, a scarcely indicated dorsal elevation 011 joint 12. Ground color pale brown, dorsal tubercles marked by small black dots. Dorsal space reddish brovn, containing an addorsal in'egiilnr white line, all edged by six crinkled brown lines; a broad flesliy vllile subdorsal line, sometimes partl'\ orange filled; lateral space whitish, partly brown and hlack filled, containing a lateral irregular whitish line, all edgd by four crinkled black lines, more or less incised and broken ; a broad white ;llbstigmatal hand; snhventriil space brown, edged by t\\m cri-ikled brov~n lines; a while sub- ventral band; pedal space whitish, edged by brown lines; a white ventral hand containing sqpentary gray spots. Feet pale, brown bordered and black dotted ; spiracles black ; no shields; setae small, dark.
Pupa in a slight cocoon of leaves and coarse silk, whitish, spotted and stieaked as described by Packard.
