NORTH AMERICAN LEPIDOPTEKA. 185 



These moths are not easily disturbed, but will suffer the twig upon 

 which they are to be handled freely without moving, and often they 

 will not take to flight even when touched. They usually rest upon 

 the two posterior pairs of legs, and the tip of the folded wings with 

 the fore legs drawn closely to the body, and the whole body forming 

 an angle of about 45° with the object upon which they are at rest. 

 In this position they will remain motionless for hours. 



Several of the moths were placed in a breeding-cage containing a 

 twig infested with Palvlnarla. Several eggs were afterwards found. 

 These were deposited singly either on the bark, the coccid scales, or 

 the cottony masses. Six days after oviposition the eggs hatched. 

 The moth seems to be two brooded." 



This is a most remarkable and interesting history, and seems as 

 yet to be unique in the family. 



I have received specimens of the insect from Central Texas and 

 New Mexico. The Texas specimens were taken in May, June, 

 August and September. The New Mexico specimens in September, 



Pallida is simply a somewhat lighter variation.
