Description of the Several Stages in Detail. 



Egs^. — Elliptical, flat, 1.1X.7 mm., milky whitish when laid on 

 glass, reticulations obscure. Laid singly or in patches of two to ten, 

 slightly overlapping. They hatch in seven days. 



Stage I. — (Plate I, Fig. 8) Structure as in Euclea ; eleven horns in 

 subdorsal row, nine in lateral row, the one on joint 5 absent. Three 

 setae on each horn, tapering, slightly enlarged and notched at the tips. 

 Color uniform, translucent whitish ; skin smooth ; head white, eye 

 black. Length .9 mm. The larva does not feed in this stage and 

 molts in two days from the time of hatching. 



Stage 11. — Head white, eye black, mouth brown ; horns spined, 

 the long subdorsals, with a bunch of black-tipped spines, the short ones 

 with one spine ; lateral row moderately spined. Color opaque whitish ; 

 dorsal depressed spots (i) paired, greenish, two pair on the incisures 

 3-4 and 4-5, those on interspaces 8-9 and 9-10 connected into a trans- 

 verse streak. No marks except a white line along the subdorsal ridge. 

 Length, .9 to 2.2 mm. 



Stage III. — Thickest through joints 4-5 ; dorsum flat, sides nearly 

 perpendicular ; lateral ridge moderate, shape as in the mature larva. 

 Subdorsal horns on joints 3, 4, 5, 8, 11 and 12 large, rounded, notlong, 

 the others very small, but with several spines, lateral horns all small. 

 Color whitish, dorsum and upper half of sides green from food ; a 

 white subdorsal line, thickened at the large horns, causing the dorsal 

 space to widen and contract. In the wide spaces on joints 4-5 and 6-7 

 a rounded patch of pale purplish pigment, and in the space 9-10 a 

 smaller whitish patch. Skin finely clear granular except on the horns. 

 Dorsal dots (i) white. Later all the dorsal patches become purple-red 

 and there is another on joints 3-4 ; subdorsal horns faintly yellowish. 

 Length, 2.1 to ■^■l n:i™- 



Stage IV. — Structure as in the mature larva. Skin clear granular, 

 the paired white dots (i) visible where the ground color is purple. 

 Markings at first as at the end of the last stage ; later the subdorsal 

 horns on joints 3 to 5 are tipped with red ; a yellow line on subdorsal 

 ridge, bent up at the large horns, the dorsal space filled in with dark 

 purple except in a space from joint 7 posteriorly to joint 9 anteriorly. 

 Sides green, the lateral horns colorless. Length, 3.2 to 4.7. mm. 



Stage V. — Horns as in Euclea delphinii, the spiracle on joint 5 

 moved up. Long horns on joints 3 to 5 and 12 red tipped, the short 

 ones pale yellow, lateral ones colorless. Colors as before, the waved
