PSYCHE. 



[March, 1901 



reticulations also in the small level micropy- 

 lar area. Dark leaf green, the beading a 

 shade paler, not white. Size .6 X -35 X .25 

 mm. 



Stage I. Head round, higher tlian wide, 

 scarcely bilobed, erect, free from but lower 

 than joint 2 ; sordid luteous, grayish on the 

 vertex, ocelli black, mouth brown ; width 

 about .2 mm. Bod}' stout and rather thick, 

 normal, smooth, incisures distinct, the seg- 

 ments a little bulging ventrally. Sordid 

 translucent white, pale green from the food ; 

 very faint brownish subdorsal mottlings the 

 whole length. Tubercles small, black in 

 white rings. Shields concolorous, uncorni- 

 fied, cervical shield faintly luteous, the rim 

 of joint 2 before wliitish. Setae small, 

 obscure. 



Stage II. Head rounded, slightly bilobed, 

 erect, slightly lov/er than joint 2 ; pale lu- 

 teous, slightly shining; width .35 mm. 

 Body short and thick, normal, incisures dis- 

 tinct; translucent, pale green from the food, 

 tubercles greenish dusky, rather distinct, 

 pale edged. Faintly indicated dusky longi- 

 tudinal lines, narrow subdorsal and broad 

 lateral, but very obscure. Thoracic feet 

 blackish; setae short, black, distinct. Ab- 

 dominal feet and obsolete shields concolor- 

 ous with body. 



Stage III. Head broad, bilobed, rounded, 

 flattened before, erect; pale yellowish, not 

 shining, ocelli black; width .6 mm. Body 

 short and thick, smooth, uniform pale green, 

 translucent, not shining, incisures folded 

 and whitish. Feet concolorous ; no shields ; 

 no marks. Tubercles minute, blackish ; 

 setae short, dusky. 



Stage IV. Head round, circular from 

 before, lobes full, slightly bilobed, erect, 

 free; light green, ocelli small, black, anten- 

 nae moderate, whitish; width 1.15 mm. 

 Body short and thick, the central segments 

 only a little longer than the end ones and 

 shaped about as in Noctuid larvae, the ends 

 being slightly contracted. Feet normal, the 

 thoracic ones moderate, the abdominal on 



joints 10 and 13, the latter with large tri- 

 angular plate; anal plate rounded; cervical 

 shield divided into two well separated ellip- 

 ses. Tubercles distinct, rather large, not 

 elevated, concolorous ; setae short, black. 

 Entirely light green without marks, the 

 plates and tubercles slightly shining, the 

 skin dull. No anal prongs. Tubercles nor- 

 mal, ia to iib equally spaced on joints 3 and 

 4 and separate. Spiracles narrowly dark 

 rimmed. 



Stage V. Head round, circular, fiat before 

 and a trace flattened on the apex; clypeus 

 two thirds to vertex, the paraclypeal pieces 

 very narrow and obscure ; finely shagreened ; 

 width 1.9 mm. Body robust, the segments 

 not elongated, the end ones proportionately 

 a little contracted, obscurely 6-annulate. 

 Feet normal, short, the anal pair triangular 

 and slightly produced at the upper angle; 

 anal plate elongated, rounded. Tubercles 

 very small, not elevated, distinct; setae 

 short, pointed ; both black. The coloration 

 varies from green to more or less heavily 

 spotted. In the former the head is luteous 

 green, subtranslucent, ocelli dark. Body- 

 green like the leaf, the folded incisures yel- 

 lowish, faint dotted whitish subdorsal and 

 lateral lines ; subventral fold yellowish ; spir- 

 acles brown rimmed; dorsal vessel darker 

 green. In the spotted form the head is 

 green mottled broadly with brown spots 

 over the vertex. Body green with many 

 fine brown specks forming triangular brown 

 spots subdorsally on joints 5 to S, pointed 

 before and in general segregated into gemi- 

 nate parallel lines. The lines are subdorsal, 

 lateral and subventral, enclosing paler spaces, 

 but very obscurely. Also a faint dorsal 

 line. The dottings are somewhat mottled, 

 heaviest centrally on the segments, con- 

 tracted, and therefore darker, on joints 10 

 to 13, the anal plates spotted. Venter rather 

 broadly green, paler lined. Feet brownish 

 dotted. 



The larvae spun very slight webs of brown- 

 ish silk in the ground at the surface and
