14 PSYCHE [February 



lately joined. A series of large, segmentary, ventral, clouded spots on the legless segments. 

 Feet all pale; no shields; setae short, stiff, white; tubercles imperceptible. Segments 

 obscurely, rather numerously annulate. 



Stage II. Head rounded, lobes large, full, but not bulging before, a little wider than 

 high ; white, a faint gray shade over vertex ; tubercles dark as also sutures of clypeus and 

 ocelli ; width .5 mm. Body moderate, normal, whitish with a bark gray tint ; dorsal space 

 broad)} pale, containing black tubercles i and ii, bordered by a double black lateral band bro- 

 ken into dashes. A more continuous and grayer subventral band. Feet and venter pale, 

 tubercles dark, setae short, pale. Segments finely, faintly annulate. No shields. The 

 marks get fainter with growth, the general appearance being light, whitish gray. 



Stage III. Head rounded bilobed, moderate, white, very faintly grayish 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 foriuer lines as rather remote dots and streaks laterally and suprastigmatallj-, 

 not forming well traceable lines. Subdorsal 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 bilobed, thick ; white, luteous freckled, blackish in inci- 

 sure with distinct black dots on the tubercles; ocelli black; width 1.9 mm. Body rather 

 slender, moderately elongate ; nearly while, the ground color pale luteous with straight white 

 subdorsal line and wavy irregular one in dorsal space, narrowly and obscurely black edged; 

 a waved suprastigmatal line, black edged; an irregular white band on subventral fold not 

 distinctly edged and a broad subventral band, straight like the subdorsal, black and brown 

 edged. Tubercles small black ; feet pale ; spiracles black ; general appearance very light 

 bark gray, the lines not contrasted with the ground color. 



Stage VI. Head rounded, bilobed, narrowed a little above, lobes full before. Fleshy 

 white, faintly mottled with light brownish; tubercles marked by distinct round black dots; 

 width 2.3 mm. Body normal, moderate, smooth, a scarcely indicated dorsal elevation 

 on joint 12. Ground color pale brown, dorsal tubercles marked by small black dots. 

 Dorsal space reddish brown, containing an addorsal irregular white line, all edged \>y six 

 crinkled brown lines; a broad fleshy white subdorsal line, sometimes partly orange filled; 

 lateral space whitish, partly brown and black filled, containing a lateral iriegular whitish 

 line, all edged by four crinkled black lines, more or less incised and broken ; a bi-oad white 

 substigmatal band; subventral space brown, edged by two crinkled brown lines; a white sub- 

 ventral band; pedal space whitish, edged by brown lines ; a white ventral band containing 

 se<^mentary 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 

 streaked as described by Packard. 



The larvae fed on several species of oak.
