basal annulus. The looping habit is lost, but the front prolegs are still somewhat the 

 smallest. It now curls round and does not spin in dropping. In the fourth stncfe the 

 aspect is quite changed, the general color being dull, dark green. The head has the 

 raottlings of a deeper brown and the characteristic brown lines appear. The second 

 pale line (from above) is obsolete, and the other fis'^e are narrowed, pure white, and 

 sharply relieved bj' dark shades. The prolegs are of nearly equal size ; the cervical 

 shield better defined : in short, except in tlie lighter substigmatal stripe and more 

 greenish color, the characters of the more normal, mature larva obtain. In the fifth 

 and sixth stages the changes are mainly in the increasing prevalence of the brown 

 and ferruginous colors, and the greater relief and intensity of the black, especiallj' 

 above the upper white lateral line. The front prolegs in the last stage are, if anything, 

 longer than the hind ones. I reproduce herewith, with a few additions, my original de- 

 scription of the 



Mature larva. — General color dingy black, appearing finely mottled and speckled 

 under a lens, with the peliferous spots placed in the normal position, but scarcely visi- 

 ble, though the soft hairs arising from them are easily seen with a lens. Four lateral 

 light lines, of almost equal thickness, and at about equal distance from each other, the 

 two uppermost white, the two lowermost yellow; a much less distinct medio-dorsal 

 white line, frequently obsolete in middle of joints, and always most distinct at the 

 divisions : a jet black line immediately above the upper lateral white one, the dorsum 

 near it, thickly mottled with dull yellow, but becoming darker as it approaches the fine 

 dorsal white line, along each side of which it is perfectly black. Space between lateral 

 light lines 1 and 2, from above, dull yellow, or reddish, the white lines being relieved 

 by a darker edge ; that between lines 2 and 3 almost black, being but slightly mottled 

 along the middle ; that between 3 and 4 yellow, mottled with pink brown, and appear- 

 ing lighter than that between 1 and 2. Venter greenish-glaucous, mottled and speckled 

 with neutral color, especiall}^ near the edge of the 4th lateral line. Legs glassy and of 

 ■same color as venter, those on thoracic joints with black claws, those on abdomen with 

 a large shiny black spot on the outside. Stigmata oval, black, and placed in the 3d la- 

 teral light line. Head highly polished, pale grayish-yellow, speckled with confluent 

 fuscous dots ; marked longitudinally by two dark lines that commence at the corners 

 of tlie mouth, approach each other towards the centre, and again recede behind ; on 

 each side are four minute polished black eyelets, placed on a light crescent-shaped ridge, 

 and from each side of this light ridge a dark mark extends more or less among the 

 •confluent spots above. Cervical shield polished and mottled like the head, with the 

 white medio-dorsal and upper lateral lines running conspicuously through it. Anal 

 plate obsolete. 



These descriptions apply to the average specimens, and, as stated on page 45, there 

 is considerable variation in all stages.
