of the seta is everted from the middle portion on hatching, sometimes 

 remaining incompletely so. No spines present on first emerging from 

 the egg. Length, .9-1.7 mm. 



Stage II. — (Plate I, fig. 2.) — Rather elongated elliptical, tail 

 rounded quadrate, joint 3 truncate in front. Setse normal, two on the 

 subdorsal ridge, one on the lateral, distinct, long, sharp pointed. The 

 middle row on the thorax is represented by two setae on joint 3, and by 

 one only or a large and a small one on joint 4. Ridges distinct, the 

 dorsum and sides concave. Head retracted ; joint 2 partly so. Skin 

 rather densely frosted with clear conic granules, not contiguous, no- 

 where produced into secondary spines. Depressed spaces hardly indi- 

 cated (1) as slight hollows, not differentiated by the granules and very 

 small. Color pale whitish green, evenly tinted. Length, 1.6-2.5 rn m - 



Stage III. — Narrowly elliptical, tail small, square. Dorsal and 

 lateral spaces broad, subventral smaller. Ridges marked, high, seg- 

 mentarily tubercular, the setse stiff, black, distinct. Color plate trans- 

 lucent whitish green, a faint white line under the subdorsal ridge, not 

 reaching either extremity. Skin with remote, low, rounded granules 

 (Plate I, fig. 4), no spines anywhere. Depressed spaces small, shal- 

 low, not sharp edged, smooth in the bottom. Length, 2.3-3.5 mm. 



Stage. IV. — Elliptical, tail produced a little and tapering, notched. 

 Whitish green, a distinct white band below the skin of subdorsal ridge 

 on joints 4-13. Lateral ridge prominent, even with the subventral 

 edge or a little beyond it. Dorsal impressed whitish dots (1) distinct 

 on the central segments, interrupting the faint green line of the dorsal 

 vessel. Skin smooth except for the remote, irregular, clear granules, 

 the surface slightly sunken to represent the depressed spaces. Lengthy 

 3.5-5.2 mm. 



Stage. V. — Somewhat more like mature larva ; tail truncate. Skin 

 more densely clear granular, the granules nearly contiguous. Subdorsal 

 ridge with a distinct yellowish white line on joints 3-13 ; a row of dor- 

 sal dots (1 ), only five of them distinct (joints 5-9). Ridges gently un- 

 dulating from the outline of rudimentary tubercles. Seta; short, distinct. 

 Depressed spaces indicated, but like the rest of the skin, granular. 

 Color, translucent green, dark, not yellowish. Head green, eyes black. 

 Length, 5.2-7 mm. 



Stage F/.— (Plate I, fig. 6.) Shape as described. Skin granules 

 transparent, contiguous, covering the whole surface. Depressed spaces 

 very small, the dorsal (1) smooth, whitish with green centers ; addorsal 

 ones (2) absent on the surface, but represented by white dots below the
