beneath the surface, leaving a small mass of loose earth be- 

 hind, not unlike that usually found around the entrance of an 

 ant's nest. The larva went to the bottom of the ordinary glass 

 tumbler containing the earth and there pupated; the burrow 

 narrowed gradually toward the bottom ; it measured eight 

 millimeters across the entrance and was slightly slanted; the 

 pupa was formed in a vertical position, the head end up and 

 about ten millimeters beneath the top of the soil. The moth 

 emerged during the night of May 19-20. 



Another larva similarly captured, confined and fed, entered 

 the earth during the night of May 19-20, 1904, and emerged 

 as an adult in the early morning of June 4, having been be- 

 neath the earth about fourteen and a half days; its larval bur- 

 row was straight and measured seventeen millimeters long, 

 seven wide at the entrance and only one and a half at extreme 

 bottom. The above moths lived in confinement without food 

 about four and a half days. The soil at the entrance of the 

 larval burrows (pupal cells) is slightly convexed.

About sixteen miles northwest of Paris, Texas, on April 3, 

 1904, a female of this species was found clinging to the stem 

 of a dead weed, the legs wrapped tightly about it. She was 

 depositing eggs. These latter had been placed in more or less 

 longitudinal rows, the female probably laying transverse rows 

 of them as she crawled slowly upward ; there were twenty-two 

 transverse rows, containing from three to eleven eggs each 

 and a total number of a hundred and twenty-one eggs. The 

 mass was covered with a very light network of hair from the 

 abdomen of the female ; it hatched on the morning of April 

 15; no external signs of embryonic development could be 

 noticed; the young hatching larva eats a large hole through 

 one side. The vacated eggs were eaten in some instances. 



Out of a mass of two hundred and ten eggs which com- 

 menced to hatch at 6 A. M., October i, 1904, after two and a 

 half days, seventy remained as yet unhatched. These eggs 

 were taken at Paris. The second larval stage diflfers from the 

 first, principally in lacking the two spots on the head and bear-
