are grayish in color, the head black, the body with a pallid, 

 soiled line across each segment, and it is clothed with long 

 silky, whitish hair. In Montgomery County, Virginia, perfect 

 embryos were found as early as September 2, 1902. 



4. Thyridopteryx ephemeraeformis Haworth (Lepid.). 



This species has been observed at Salem, \'irginia; Annapo- 

 lis, Maryland, and Paris, Texas. At Annapolis, a male issued 

 September 21, 1902, a female three days later; in the same year 

 the emergence at Salem, Virginia, occurred at the same time 

 or somewhat later, the larvae being half grown or more by 

 the end of July. The species also occurs at Butler, Illinois, and 

 comes to maturity there in the late summer. 



5. Lophyrus abbottii (Hym.). 



This species in late July, 1902, was defoliating portions of 

 several white pine trees at Blacksburg, Virginia. The larvae 

 vary somewhat in detailed coloration ; in some of the specimens 

 the black dots at the base of the prolegs are absent, and gome- 

 times the first thoracic segment is dotted with black. Observ- 

 ing a cluster of nearly full-grown larvae at rest, occasionally 

 one is seen to throw back its fore body (head plus thorax) 

 stiffly, holding itself thus for quite a while. Their natural po- 

 sition of rest is to be stretched along a leaf; when disturbed 

 their bodies are jerked backward quickly and a glue-like fluid 

 is emitted from the mouth. When feeding, they begin at the 

 apex of the pine needle or leaf and eat it down to its base; a 

 colony thus denudes the terminal portions of a branch. Pupa- 

 tion commenced on August 2, a number of larvae having been 

 confined in a rearing cage. Subsequently a few adults emerg- 

 ed late in August and some others not until the following July. 

 Pupation occurred in cocoons made within the earth in the 

 cage. A dipterous parasite was noted. 



6. Notes on Automeris io Fabricius (Lepid.). 



A gravid female of this species, captured at Blacksburg, Vir- 

 ginia, July 7, 1902, and roughly confined, deposited a number 

 of eggs the same day ; on July 9 the yellow end-spot on the 

 eggs had changed to black; on July 21 the color of the eggs
