from the body of the female, which gives them a very .striking appear- 

 ance and at lirst sight seems to be a decided disadvantage, but which 

 possibly is of some value in protecting them from parasites. This 

 wears off in a few days, often leaving a margin of white around the 

 eggs. Eggs known to have ])een laid August IT hatched about 7 a. m. 

 on the 25th almost simultaneously. About twenty minutes later the 

 nymphs clianged from a bright green to a metallic lead color and had 

 increased very rapidly to about twice the size at which they emerged. 

 On August 12 more adults were found on okra than on any other plant. 

 Eggs were common on the bloodweed, and were also found at College 

 Station on catalpa. Onl}^ a few sporadic adults were found on cotton. 

 Nymphs were most common along the Brazos River on young elm, 

 box elder, mulberry, and bloodweed. About the middle of August a 

 very large percentage of the eggs became parasitized by Ooetonus 

 homalodiscce Ashm. n. sp., so that it was exceedingly difficult to rear 

 nymphs. The larva of a chrysopid was also observed feeding on the 

 young nymphs. This larva, which was colored like the i)etiole at the 

 base of tlie leaf, awaited its prey upon the red spot at that point. On 

 August 20 an egg mass was found deposited in the bract of the invo- 

 lucre in a field cage in which adults had been placed on cotton in the 

 Brazos l)ottoni. Tliese were parasitized, but six eggs were found in 

 one small l)oll. This is the onh' instance in which any injury to cot- 

 ton was observed under tield conditions. On August 2<S the adults 

 were quite abundant on lig trees and on cotton near the Brazos, but no 

 eggs were found on tig. On August 24 eggs were taken on okra and 

 catalpa. By Septem))er 1 the adults Ave re much less common on cow- 

 peas, but one lot of eggs deposited September 15 hatched the 22d. On 

 October 8 adults and nymphs in the last stage were taken on the tig 

 trees, but no eggs could be fovnid. 



At Terrell a nymph with wing pads just showing was taken August 

 8, and became mature upon molting August 15. On August 21, adults 

 were found in the field, which from their bright color and texture 

 were evidently newly transformed. Eggs laid Septeml)er (! hatched 

 September 12. 



These observations may be briefl}' summarized as follows:
