the full notes taken during their development, but this has been 

 done, doubtless, by a number of European writers. 



The larvae of C. clocata and nupta hide themselves when not 

 eating (in daylight) under leaves and paper in the bottom of 

 the jar, while those of C. elccta and fraxini remain on the plant 

 stems, rarely, even when making ready to moult, go to the 

 bottom. 



While busy with the above-mentioned species, the few eggs 

 of Catocala ilia, which Mr. E. A. Dodge had given me, hatched 

 on the 8th and gth of April. Before the first moult, which 

 occurred on the i8th, the larvae are light colored, striped longi- 

 tudinally, with fine lighter and darker lines. Four low lateral 

 darker-brown, roundish spots to third abdominal segment and 

 a smaller one in front of the last abdominal segment. The 

 head hardly darker than the body. 



Before the second moult, which occurred on the 2ist, the 

 larva is somewhat darker, especially along the dorsum near the 

 posterior end. The lower row of lateral large spots are strongly 

 pronounced and black. Dorso-laterally, there is a row of black 

 dots (to each side). These rows, less strong, are present be- 

 fore the first moult. 



Head black. Before the third moult, the larva is nearly three- 

 quarters of an inch long, gray, with a line of elongate, some- 

 what-lunulate dark dashes, mid-laterally, and two pairs of sub- 

 . dorsal dark, elongate spots on the two segments just in front 

 of the first pair of prolegs. Head grey. 



The larva moulted the third time on the 25th. Body light 

 ashen gray, the black longitudinal lunulate lines almost disap- 

 pearing. The pro as well as true legs light gray, with black 

 dots (two to true leg and one to the pro-leg) . The longitudinal, 

 lateral lunulate lines dim and but little darker than the body 

 color. The body of this larva from the hatching is rough or 

 sand-papery looking. After the third moult the body is more 

 visibly covered with low, raspy tubercles and short bristles. In 

 front of the fourth pro-leg on either side of the dorsum is a 

 small quadrangular black spot. Head light gray, with a brown- 

 ish lateral dash. A latero-ventral line of fringe or setae. 



Just after the fourth moult, the larva is over an inch long,
