PSYCHE.

normal. Feet normal for Geometridae. 

 Color greenish brown, with faint, narrow 

 dorsal and lateral brown lines, the latter 

 expanding into spots at the projections; 

 venter darkly shaded. Setae both on head 

 and body short with swollen tips. Later the 

 larva appears rather uniformly dark brown. 

 The projections appear the whole length of 

 the abdomen, but are largest centrally. 



Stage II. Roughened; head round, a 

 slight point at apex; width about .4 mm. 

 Tubercles all rather large, especially on the 

 cervical shield and joint 13 ; setae iv and v 

 of joints 5 to 9 borne on prominent projec- 

 tions. Skin finely spinulose granular. 

 Color yellowish brown, the projections 

 darker, I'eddish ; tubercles pale; all grizzled 

 by the pale granules. Setae pale, short, 

 pointed. 



Stage III. More roughened; subventral 

 processes forked i^\\ and v), sharp ; also 

 smaller lateral points anteriorly and poste- 

 riorly ; a pair of proininent points on joint 2 

 and on joint 13 before the triangular anal 

 plate. Head rounded, slightly bilobed ; 

 width about .6 mm. Coloryellowish brown, 

 densely covered with pale yellow granules, 

 slightly mottled with dark red brown, espe- 

 cially in patches below the processes. Tuber- 

 cles conic, high; setae short, stiff, white. 

 No well defined markings. 



Stage IV. Essentially the same. Head 

 about .8 mm. Lateral projections of joints 

 5 to 9 flattened, furcate, the anterior limb 

 longest, bearing tubercle ^', excavate before, 

 sloping behind; the spiracle borne on the 

 dor.sal aspect of the projection ; tubercles iv 

 and V conic, pale. Other points on joints 2 

 to 4 and 12 as before, scarcely anv on joints 

 10 and II. Color rusty brown dorsally, 

 grayish ventralh-. the \entral aspect of the 



projections and a series of intersegmental 

 dorsal marks dark brown ; narrow, obscure 

 dorsal and subdorsal lines, the latter distinct 

 on joints 10 to 12. Skin densely pale gran- 

 ular. 



Stage I'. Head bilobed, roughened ; width 

 about 1.2 mm. Dead leaf brown, brighter 

 dorsally posteriorly. Three dark brown, 

 triangular marks on joints 5 to 7 anteriorly. 

 Lateral processes obliquely streaked with 

 brown and pale below, especially on joints 

 5 and 6, furcate as' before. Tubercles, high ; 

 ii of joint 12 very high; many slightly 

 produced tubercles on the thorax ; set:e 

 small. Markings faint, but a pale dorsal 

 line and a subdorsal and medio-ventral can 

 be traced. Skin rough as before. 



Stage VI. Head bilobed, the lobes slightly 

 pointed, roughened granular, rusty brown ; 

 width 1.6 mm. Bod^' granular, the tuber- 

 cles prominent, single, normal. Lateral 

 processes on joints 5 and 9 small, those of 6 

 to 8 large, furcate, bearing tubercles iv and 

 v; four cones on the cervical shield; a 

 subdorsal elevation with three cones on 

 joints 3 and 4; a slight subventral prom- 

 inence on joints 10 to 12; tubercles ii on 

 joint 12 form long cones. All roughened 

 granular; color dead leaf brown, a little 

 variegated, being slightly grayish dorsally on 

 joints 6 to 8 faintly brown lined longitudi- 

 nally and with dark brown dots on joints 6 

 to 9 anteriorly and a bent white lateral line 

 on joints 10 to I2. Spiracles dark ringed. 

 The appearance is as in the previous stages. 

 This stage lasted 30 days. 



Food plant. Oak. The larvae are slug- 

 gish, solitary, and rest on the brown leaf 

 where they have fed, their ragged appear- 

 ance harmonizing with the mutilated and 

 partly withered leaf.
