Mr. C. L. Marlatt x reared adults on June 5, 1896, from larva? that 

 were collected May 2 of that year at Xuecestown, Tex. Mr. Albert 

 Koebele 2 reared adults on September 2 and 15, 1885, from larvae 

 collected June 21 at Rattlesnake Bridge, Eldorado County, Cal. 

 Mr. Koebele also noticed the entrance holes of young larva? and the 

 exit holes of older larva? in the pod husks. He says, "The 

 larva? * - * * spun a web on the bottom of the jar in which they 

 pupated." 



Mr. Theodore Pergande 3 received a number of larva? from Mr. 

 E. A. Schwarz collected at Cocoanut Grove, Fla., on May 9, 1887, and 

 on May 26 reared an adult from this material. More material from 

 the same source was received on June 1, and on the 24th three more 

 adults emerged. 



Mr. H. O. Marsh obtained adults from January 9 to February 25, 

 1909, from larva? collected October 22, 1908, at Anaheim, Cal.* 



These observations indicate that two generations a year is char- 

 acteristic of this species, the adults of the first appearing in early 

 June and those of the second in September. The adults obtained in 

 January and February were reared under laboratory conditions, which 

 very probably accelerated their development. In the more southern 

 parts of its range this species may have more. than two generations. 



FIELD WORK. 



July 21, 1909, while examining the seed pods of the common 

 lupine (Lupinus sp.) many were found to contain lepidopterous 

 larva?. In such pods the seeds were always more or less destroyed. 

 The pods also contained a mass of frass which was held together by a 

 loosely constructed web. A few days later, on examining the col- 

 lected material, several of the pods were found with newly eaten 

 holes in the sides and two larva? were found with half their bodies 

 within fresh pods. 



On August 7 one of the larva?, very plump, was found still in the 

 pod, it having in the meantime become suffused with a rosy color. 

 This larva had constructed a loose silken cocoon, through which its 

 body could be easily seen. Ten days later the larva pupated and 

 emerged as an adult (Etiella zinckenella schisticolor) September 28. 



In the rearing cages with solid bases most of the larva? left the seed 

 pods and spun their cocoons among the litter and dirt in the bottom 

 of the cages. In cages with bottoms of earth the larva? always bur- 

 rowed 2 or 3 inches below the surface to pupate. 



On August 1, 1910, Mr. M. W. Evans, of the Bureau of Plant 

 Industry, told the author of a larva that he was finding in the field-pea
