one-laved mass. Thev are of a vellowish white color, nearly 

 spherical, O.S mm. in diameter, minntely reticnlated at upper 

 pole and radrately ridg'ed from it down the sides. 



They hatch in a week or ten days. The caterpillars molt five 

 times at intervals of four to six days, attaining their fnll-ii'rowth 

 (36-40 mm.) in three to five Aveeks (sometimes mnch longer 

 than this in hot, dry seasons). 



The full-grown cater])ilhir (1^1. IT, fig. 4) is of a dirty 

 brownish color, with a liroad liuhter brown stripe on the back; 

 under side dirty whitish. Tubercles black, a row of them on 

 each side of the dorsal lighter stripe, are larger and more con- 

 spicuous than the rest. ITairs short, black. Spiracles oval, 

 black. Head rather small jn-oportionately, })rown with black- 

 ish spot above each eye cluster, and two black bars in front con- 

 verging above. The dorsal i)art of first segment behind head 

 very dark brown. The full-grown cater])illar forms an earthen 

 cell in the ground a few inches below the surface. After four 

 to six days it transforms to the ])upa which is similar in form 

 to the pupa of CirpJiis unipunda. about 17 nun. hnig, and of 

 a pale yellowish brown color. The moth appears in 15 to 20 

 days, which makes a period of about two months from the time 

 eggs were laid. 



The moth (PI. II, fig. o) with wings expanded is about 1| 

 inches, or 40 mm. It is of a whitish grey color. The fore 

 wings have a longitudinal white streak for more than half their 

 length, behind which is a shorter blackish streak, which in turn 

 has a yellowish streak behind it. The veins are marked with 

 dark lines, and there is a row of dark dots on termen. Hind 

 wings a little darker, with pale fringe. The wings when at rest 

 are held straight backward over "the back, often tipped so as to 

 lie close along the sides of abdomen.
