The full-grown caterpillar (Plate III, fig. 4) is 35-40 mm. 

 long, or about one and one-half inches. General color greenish 

 brown with longitudinal blackish stripes on back and sides, 

 much paler below. The stripes are as follows: a wide, pale 

 blackish stripe on the back with an interrupted white line in 

 the middle ; outside of this is a narrow pinkish brown stripe ; 

 then next a still wider blackish stripe darker along its lower 

 edge, wdiich contains the black oval spiracles, or breathing 

 pores ; below this is another pinkish brown stripe having whitish 

 lines on each edge. The head is pale brown, each lobe with a 

 network of darker brown and running up and down in front 

 are two blackish bands diverging below. First segment behind 

 head nearly all brown dorsallj. A dark brown spot on outer 

 side of each proleg. Hairs small, situated in inconspicuous 

 tubercles. 



The coloration varies somewhat and the stripes are some- 

 times less distinct. The vounger stages are colored about the 

 same; often paler, and sometimes iiearly black. 



When full-grown, the caterpillar burrows into the Soil and 

 at a de])th of two to four inches constructs an oval earthen cell, 

 within which after a few days it transforms to the pu])a (Plate 

 III, fig. 5). The pupa is of a shiny dark brown color, about 

 18 mm. long and 4.5 mm. thick, rounded at anterior end and 

 tapering posteriorly to a blunt point which is armed with two 

 nearly straight parallel spines, hooked at the tip, and placed 

 near together. There are four other slender hooked bristles, one 

 latei-al and another a little dorsal of each of the larger spines 

 (Plate III, fig. 6). The wing-cases terminate roundedly at the 

 apex of the fourth abdominal segment. On the bases of abdom- 

 inal segments 5, 6 and 7 is a dorsal black line containing a row 

 of 12-20 pits. These segments are movable. 



The moth emerges from the pu]ia in about ten days to two 

 weeks. It makes its way al)ove the surface, and, clinging to 

 some object, its soft wings soon become expanded and dried, 

 and the moth is fully matured, after a period of from six to 

 eight weeks, or sometimes more, according to temperature.
