" Egg. Creamy white when first laid, gradually turning 

 to an orange-rufous color before hatching. Form ellipti- 

 cal oval, with the ends slightly truncate ; size, .39 mm. by 

 .3 mm. The egg-shell has eighteen longitudinal ridges and 

 numerous smaller transverse ridges. 



"Larva, First Stage. Head diameter, .15 min. ; body 

 diameter, .125 mm. ; length, .875 mm. Color a smutty, 

 translucent white, with irregular reddish spots on the middle 

 line of the back ; head a pale amber color. Scattered light- 

 colored hairs occur on the head and body. Five pairs of 

 prolegs occur on the seventh to the tenth inclusive and 

 thirteenth segments." (Felt.) 



"The full-grown larva is about one inch in length, of 

 a slender, cylindrical form, and of a pinkish- white color, 

 slightly tinged with brown. The head is dark brown or 

 black. There are several stiff bristles or hairs upon each 

 segment. 



"This Crambid works upon the centre portion of the 

 plant, just beneath the surface of the soil. It spins silken 

 galleries which extend from the plant several inches just 

 beneath the surface of the soil. Some plants were nearly 

 girdled, and the larvae were frequently found imbedded in 

 cavities where they had fed upon the plants. In some in- 

 stances as many as thirty larvae were found in a single hill 

 of corn, and in many hills the plants had been entirely 

 destroyed." (Beckwith.)
