[May, 1901 



cupt a faintly traced brownish subdorsal line. 

 Setae short, dark. Later became sordid 

 green from the food, with faint traces of 

 narrow brown line on dorsum and a sub- 

 dorsal line, which u'idens into a spot on 

 joint 6. 



Stage II. Head slightly bilobed, higher 

 than wide, erect, free; dull luteous greenish, 

 ocelli black; width about .5 mm. Body 

 moderate, the central segments not much 

 elongated; tubercles rounded and slightly 

 elevated, concolorous; setae short, dark. 

 Translucent yellowish, food green, very 

 finely brown dotted, the dots forming 

 obscurely many longitudinal lines. A large 

 brown spot laterally on joint 6. The brown 

 is heavier ventrally, forming a distinct shade, 

 likewise divided into ill-formed lines. Feet 

 normal, the anal pair triangular, not ex- 

 ceeded by the anal plate, immaculate. 



Stage III. Head rounded, slightly bilobed, 

 flattened before, higher than joint 2, but held 

 obliquely ; pale luteous, faintly brownish 

 mottled, whitish on the eyes and margin of 

 cheeks; width .75 mm. Body moderate, 

 cvlindrical, smooth, the incisures folded. 

 Tubercles obsolete, but the setae rather long, 

 black, all distinctly visible, i to viii ; ia to lib 

 of thorax evenly separated; pointed and 

 black, both on head and body. Green, mostly 

 b}' transparency, seen without a lens marked 

 only by the large brown spot on joint 6, 

 which rests on top of the spiracle; with a 

 lens very faintly longitudinally whitish 

 lined, the lines separated by pale brownish 

 dottings, heavier ventrally. Abdominal 

 feet concolorous ; thoracic ones blackish 

 shaded. The white lines are dorsal, sub- 

 dorsal, lateral, stigmatal, subventral and 

 ventral, the two latter the most obscure. 



Stage IV. Head rounded, slightly bilobed, 



clypeus a little depressed, free, oblique; 

 green, faintly purplish mottled; width 11 

 mm. Body moderate, segments slightly 

 moniliform, a little roughened by the dis- 

 tinct, concolorous tubercles. Setae rather 

 long, black. Green, obscurely dotted-lined 

 with white in dorsal, subdorsal, lateral, supra- 

 stigmatal lines ; tracheal line, yellowish ; 

 following this a subventral line, all alike, 

 narrow. A dark brown spot edged with 

 clouded paler brown above the spiracle on 

 joint 6. Thoracic feet, brown dotted. Shields 

 concolorous, not cornified, weakly lined. 

 Incisures of joints 5 to 9 folded, whitish. 



Stage V. Head rounded, held obliquely 

 flat, clypeus slightly elevated, paraclypeal 

 pieces not reaching the vertex; green, 

 mottled and streaked with white, tips of 

 mouth parts slightly brownish ; width 17. 

 mm. Body moderate, normal, anal feet tri- 

 angular with small posterior point bearing 

 a seta shorter than the subanal prongs. 

 Tubercles small, setae distinct, brown. 

 Body green, a dark green dorsal band with 

 central broken white line; subdorsal band 

 broad, greenish white, obscurely dotted and 

 triplicate. Two faint broken whitish lines 

 above the spiracle, one on stigmatal fold, 

 two in subventral space, with traces of still 

 paler ones between the latter and as medi- 

 oventral line ; all obscure and broken into 

 dots. A brown patch above the spiracle on 

 joint 6. Spiracles pale ocherous. Thoracic 

 feet of joint 10 shaded with vinous. No dis- 

 colorous shields. Central incisures folded, 

 3'ellowish.
