The perfect embryo of the parasite fills the whole interior 

 of the host egg, which finally darkens. 



12. The Occurrence of Chalcis ovata Say in Texas (Hymen.) 

 The adults of this species were captured on the following 



dates at Paris, Texas, in 1904, from a wire screen around a 

 back porch of a residence: March 2, 21, 22, 24 and 30. Up 

 to March 24 there were only a few specimens. Next day they 

 were much more numerous, about twenty specimens; on March 

 30, nearly two hundred specimens were obtained. On May 7 

 it was noted that the adults had not been seen for many days 

 and in fact they were not noticed again until October 12, when 

 an adult was found on a cotton leaf in the field. 



13. Basilarchia archippus Cramer (Lepid.). 



A nearly full-grown larva of this species was obtained at 

 Blacksburg, Virginia, June 28, 1902, and kept in the labora- 

 tory. It was on a willow, upon which it fed by commencing 

 at the outer edge of a leaf and eating in about half-way to the 

 mid-rib, continuing thus until a rectangular piece had been eat- 

 en from the margin of the leaf; it then ate out the remaining 

 rectangular leaf portion down to the mid-rib. It feeds jerkily, 

 the head being lowered every time the larva bites. 



On the morning of July 2, this larva was found to have 

 constructed a large groundwork of silk, from which it was sus- 

 pended in preparation for pupation. The chrysalis appeared 

 on the next morning and the adult emerged during the early 

 afternoon of July 8, or after about four and a half days. July 

 7, 1902, another larva was obtained from willow, full-grown. 

 In the early afternoon of July 8, it was found suspended from 

 a pad of silk preparatory for pupation ; the abdomen was curv- 

 ed upward, the thorax humped, the head tucked under. At 

 3:15 P. M., the same day, an inner squirming motion of the 

 larva was noticed in the form of quick convulsions lasting 

 about twenty minutes, followed immediately by a split of the 

 integument along the thorax ; the chrysalis, by alternately 

 lengthening and shortening its body, quickly freed itself from 

 the larval integument.
