the truncate end, arranged in nearly regular 

 longitudinal rows for two-thirds the length, 

 confused into normal reticulations at the de- 

 pressed third ; pits rather deep, well-marked. 

 Length .7, width .5, height about .3 mm. 



Stage I. Head rounded, erect, pale, yel- 

 lowish, the sutures faintly and mouth brown, 

 ocelli black. Body normal, short and thick, 

 yellowish with distinct green tint and fine, 

 discreet, purple brown lines, about as wide 

 as the intervening spaces, dorsal (distinct on 

 the cervical shield), subdorsal, lateral, stig- 

 mata! and fainter subventral ones. Shields 

 all concolorous ; tubercles obscure; setae 

 short, stiff, black, enlarged at tips. Feet nor- 

 mal, pale. Shields faintly lined. 



Stage II. Head round, erect, free, green- 

 ish luteous, mouth brown, eye black ; smooth, 

 shining; width .5 mm. Body normal, mod- 

 erate, smooth, green with dorsal, subdorsal 

 and lateral pulverulent, subgeminate, black- 

 isli bands and a single suprastigmatal one ; 

 subventral fold pale. Tubercles elevated, 

 concolorous ; setae short, dark, capitate. 

 Shields undifferentiated. Thoracic feet faint- 

 ly reddish, abdominal ones green. Subven- 

 tral and ventral lines more dotted and broken, 

 geminate, blackish. 



Stage in. Head round, erect, broad, flat 

 before, vertex slightly under joint 2 ; pale 

 green, faintly brown shaded on the sides 

 above the black ocelli ; width .9 mm. Body 

 robust, moderate, uniform, incisiu'es not de- 

 pressed, segments not elongate. Whitish 



green, opaque ; addorsal, subdorsal, lateral 

 geminate crinkly blackish lines, darker green 

 filled, uniform over the cervical shield but 

 replaced b\' yellowish green on the anal 

 plate; a single suprastigmatal line; sub- 

 venter and venter 3'ellowish green with two 

 subventral and a single ventral greenish 

 black lines. Tubercles black, minute; setae 

 short. Feet pale, the abdominal ones very 

 faintly lined. 



Stage IV. Head rounded, erect, free ; all 

 leaf green ; clypeus rather high, ocelli black; 

 width 1.3 mm. Body rather short, as before. 

 Green with the narrow blackish, double, pale- 

 filled lines as before but both dorsally and 

 ventrally practically alike. Subventral fold 

 wliitish. Feet green, the anal ones with tri- 

 angular shields like the anal plate. No cer- 

 vical shield. Tubercles small, concolorous, 

 with short, pointed black setae. The lines 

 are addorsal, subdorsal and lateral (substig- 

 matal-subventral fold, not dark edged), sub- 

 ventral and ad\entral, all geminate, pale, 

 almost whitish filled. Later the color pales 

 and the lines look whitish with dark green 

 edges. Subventral fold white; dorsal in- 

 cisures folded, yellowish white. A short, 

 robust larva, uniform, the segments not 

 elongate.

THE HATCHING OF EAGLES IMPERIALIS. 



BY CAROLINE G. SOULE, BROOKLINE, MASS. 



Eggs of Eacles imperialis had a red line 

 part of the way around the edge of each. As 

 the larva developed this line became broken, 

 and, on the day before hatching, showed the 

 red dashes to be the dorsal tubercles of the 



larva. This could be seen without a lens, 

 but a fifteen-diameters glass showed also the 

 setae at the top of each tubercle, those on the 

 four tubercles over the head being black, the 

 others white. When the larva hatched the red
