catf, making the egg not imicli longer than 

 wide ; the other end slightly depressed, 

 rounded ; truncate end slightly concave. 

 .Smooth, uniformly and rather finely retic- 

 ulate, the reticulations irregularly hexag- 

 onal, slightly raised, subgranular, the areas 

 flat. Truncate end only faintly reticulate, 

 .the margin a smooth rim, a dark spot at tlie 

 micropyle. Pale yellowish green, soon turn- 

 ing sordid lilac and darkening .still further 

 before hatching. Size 1.8X.7X.S mm. The 

 eggs lie on the ground over winter. 



Stage I. Head rounded, not bilobed, 

 smooth, wider tlian higli, clypeus moderate ; 

 blackish, paler and biowiiish on the face; 

 width about .3 mm. Body normal, cylindri- 

 cal, segments subnioniliform ; rather short, 

 feet normal. Joint 3 whitish, the rest with 

 broad dorsal, narrower but still broad sub- 

 dorsal and very broad ventral dark brown 

 bands. Tubercles elevated; setae short, 

 dark, witli slightly enlarged tip.s. Segments 

 obscurely, rather numerously annulate. 

 Shields, plates and tubercles blackish. The 

 larva pales with growth, the dorsal band be- 

 comes paler than the subdorsal one and gray- 

 i.sh, all faintly green tinted. The dark 

 transverse cervical shield looks detached in 

 the white area of joint 2. 



Stage II. Head about .6 mm., erect, 

 rounded, moderately bilobed, the lobes full ; 

 clypeus rather liigh; pale yellow, shining, a 

 gray patch at the verte.v of each lobe ; mouth 

 brown, the large ocelli black. Body normal, 

 moderate ; tubercles elevated, rather large but 

 concolorous ; setae short, dark. Shields all 

 membranous, concolorous. A narrow black 

 subdorsal line, absent on tlie shields ; two 

 quadrate lateral black patches per segment, 

 obscurely joined by obsolete brownish lateral 

 and stigmatal lines ; a narrow brown sub- 

 ventral line, bimaculate with blackish seg- 

 mentarily. Obscure geminate, submaculate, 

 brownish ventral line. Feet dusky shaded. 



Stage III. Head rounded, pale yellow 

 with circular black spots on the epicranial 

 setae, over eyes, a line on back of occiput 

 and patches at apex of paraclypeus, clypeus 



andepistoma; antennae short, labrum mod- 

 erate ; width I mm. Body pale yellow, cervi- 

 cal shield and anal plate with four black spots ; 

 leg shield and sides of joint 2 also spotted. 

 Subdorsal line fine, black, not cutting the 

 shields ; lateral and stigm.ital lines brown, 

 broken at the spiracles, joined by bisegmen- 

 lal black patches ; traces of a line just below 

 subventral fold; subventral line black sub- 

 maculate; adventral line double, brownish. 

 Spiracles black in whitish areas. Segments 

 annulate, not shining. 



Stage /[' Head slightly bilobed, the 

 lobes full laterally, clypeus large, not high, 

 triangular, the sutures not deep but distinct, 

 paraclypeal sutures faint; light yellow with 

 four round black spots outwardly on each 

 lobe, a spot over ocelli and some smaller 

 brownish ones on clypeus; labrum white; 

 Avidth 1.7 mm. Thoracic feet close together, 

 abdominal ones on joints 12 and 13. Body- 

 light yellow, segments about 12-annulate, 

 but somewhat irregularly ; very narrow deep 

 lirown longitudinal lines, the subdorsal dis- 

 tinct, lateral suprastigmatal and stigmatal 

 faint, the two latter connected before and 

 behind each spiracle by a conspicuous black 

 patch ; spiracle surrounded by a white patch 

 subventral line just below the subventral 

 ridge faint ; a pedal line submaculate in 

 black ; two ventral lines on each side, rather 

 distinct. Abdominal feet with brown black 

 spots similar to those on the head. Thoracic 

 feet less distinctly marked with brown. 



Stage V. As in the penultimate stage ; 

 width of head 2.4 mm. See description of 

 this stage by Scudder (P.syciie, VI, 124, 

 1891). 



Cocoon an open net of \cIlow silk spun 

 among leaves. 



Pupa as described by Scudder. 



Larvae from Woods Holl, Mass.. and Bell- 

 port, N. Y. Eggs were sent me from Non- 

 quitt, Mass., by Miss C. G. Soule. The eggs 

 are laid in September and hatch the follow- 

 ing spring. Larval stages p.assed slowly.
