slightly shining, smooth. A round, black, lateral spot on segments 4 to 8. 

 Tubercles and shields obsolete. 



Stugc III. Head .75 mm. Whitish, not shining, green tinted. Body 

 slender, green, whitish subventrally, not shining; a broad smoky lateral 

 shade, containing in its lower part round segmentary black spots on 

 joints 4 to 9. No shields nor tubercles. 



Stage IV. As in the previous stage, green, with black lateral line and 

 spots. Width of head, 1.3 mm. 



Stage V. Width of head, 1.9 mm. As previously described by me.* 



Graphiphora oviducta Guenee. 



The larva closelj* resembles that of G. iitfula Grote,t but is darker, and 

 the light patch on the cervical shield occupies only the posterior third, 

 instead of two-thirds. 



Egg. Spherical, the base scarcely flattened, slightly higher than wide. 

 Waxy white; about 48 ribs, diminishing somewhat at the ends, mostly by 

 becoming confluent in pairs at the terminal third, stopping at the micro- 

 pyle, which is slightly depressed. Ribs low, closely beaded; no cross 

 striae. Shape a little irregular, the basal end often, considerably obliquely 

 flattened by the pressure of deposition. Diameter, .6 mm. 



Stage I. Head .3 mm. slightly bilobed, shining, with cervical shield 

 black. Body robust, large,' rather sharply rounded posteriorly, joint 12 

 slightly bulbous; a small black anal plate. Body transparent, green from 

 the food, faintly shaded with brown, more so posteriorly, the anterior end 

 being slightly attenuated and greener. Tubercles very small, black, 

 rounded, invisible to a low-power lens except on joint 12. Setae small, 

 obscure. Feet normal, short, the thoracic ones faintly blackish. 



Stage II. Head .4 mm., rounded, shining black. Body Noctuiform, 

 12 slightly enlarged, all darkly blackish shaded. Shields and large 

 tubercles black; setae distinct, pale at tips. 



Stage III. Head .6 mm., with shields and tubercles shijiing black. 

 Body darkly sordid, with a greenish tint, brown shaded across the centers 

 of the segments; short and robust; feet normal. Setae distinct, blackish, 

 tubercles large. There are traces of a broken whitish dorsal line, most 

 distinct intersegmentally ; joint 12 slightly enlarged, its tubercles i and ii 

 in a square. 



Stage IV. Head i mm., dark brown, shining, the apex under joint 2; 

 cervical and anal plates black, the shield quadrate, with a pale tiansverse 

 bar on the posterior edge. Body shagreened, d-ull black, greenish over the 

 thorax, and paler subventrally ; joint 12 slightly enlarged, with a subdorsal 

 wedge-shaped dilution, the point directed posteriorly. Tubercles large, 

 blackish or black; setas coarse and distinct; iv is larger than the black 

 spiracle, the seta situated above its middle. Faint traces of a wavy sub- 

 dorsal line continuing the dilution of joint 12.
