306 ENTOMOLOGICAL NEWS [Dec., '22 



Brought to Los Angeles, most of the larvae ceased feeding 

 and in a few days were dead, apparently unable to adapt them- 

 selves to a seacoast climate so much in contrast with the dry- 

 ness of the desert. In fact, I have had this same difficulty with 

 all the eggs and la/vae I have brought in from the desert. 

 Larvae of Pholisora Jibya Scudder, though supplied with abso- 

 lutely fresh sprigs of their food-plant, could not be induced to 

 touch them. Likewise, larvae of Melitaca chara Edwards re- 

 fused their Bclcpcronc and soon passed away. And this sea- 

 son not a single one of over fifty eggs of Atlides halcsus 

 Hiibner has hatched, although I can see that the embryos have 

 apparently fully developed. But half grown larvae do not seem 

 to mind the change in the least, and readily go on with their 

 transformations. 



So but two of my cnfala larvae survived their visit to Los 

 Angeles, and the record of their transitions is as follows: 



Eggs laid October 23rd, 1920 



Eggs hatched October 30th, 1920 



Larvae passed first moult November 15th, 1920 



Larvae passed second moult December 28th, 1920 



Larvae passed third moult February 2nd, 1921 



Larvae passed fourth moult March llth, 1921 



Pupated April 1st, 1921 



Images emerged April 24th, 1921 



This makes a total of 184 days from egg to imago, but very 

 probably on the desert, under natural conditions, the larvae 

 mature much more quickly and pass the winter in a pupal state. 



There is nothing of unusual interest to record in the behavior 

 of the young larvae. They form the usual type of vertical nest 

 by drawing together the edges of a blade of grass with ten or 

 a dozen loose strands of silk. In later stages the nest is more 

 perfectly closed, a cylinder being formed in which the larva 

 remains hidden from view and apparently feeding entirely by 

 night. They were extremely sluggish, remaining at times 

 motionless for days at a stretch. 



Egg. Hemispherical, the base sharply flattened, 1.04 mm. in diameter. 

 From base sloping at first very gradually, then from upper two-thirds 

 rather rapidly, to the narrow, rounded summit, where the diameter is 

 but .30 mm. The micropyle is in a shallow weak pit and difficult to 

 detect. The surface of egg rather evenly broken by a delicate tracery
