verse of illecta which never seems to try to conceal itself nor 

 does it cease eating, day or night. Innubens at maturity makes 

 some attempt to conceal itself but in captivity, feeds all the 

 time. Parta and unijuga, like ilia, seem to feed only at night 

 and more or less conceal themselves by day. 



May 5th larva C. parta one inch long, dead-twig brown with 

 a slightly lighter middorsal row of "sausage links." Head, 

 true and prolegs, body color. Black dashes on the side of the 

 head. 



The first egg of Catocala relicta var bianca hatched May 

 5th. 



It might be well to give a condensed description of the ilia 

 larva. When full grown this caterpillar is from 23/3 to 3 

 inches long, when at rest, and robust. Rather a light grayish 

 in color with a tinge of green. Tubercles ashen. Over the 

 3d pair of prolegs is a darker cross band. True and prolegs gray. 

 The lateral setae are short. Head rounded with narrow, dark 

 brown dashes from the center above, half way to the mouth, 

 outlining two large eyelike gray spots above with a small cen- 

 tral lighter tubercle. The whole larva is quite light. 



Eggs of cara and relicta began hatching on May 8th. On 

 May loth eggs of arnica hatched and concumbens on the 

 eleventh. 



Eggs of C. ultronia collected by the junior author hatched 

 on the 2 ist of April and the young larvae were rather elongate, 

 brownish with a darker head. On the 3Oth, the larvae were 

 one-half inch long and very slender, rather dark lead color 

 with a lighter middorsal longitudinal streak and with a sharp 

 distinct hump over the third pair of prolegs. On May 5th the 

 caterpillars were three-fourths of an inch long, dark brown 

 with a light middorsal narrow band or line. A red spine-like tu- 

 bercle over the 3d pair of prolegs as in the larva of C. paran- 

 yinpha (European). Head lobed or tubercled above. True 

 legs light in color. On May nth, the larva one inch long 

 lead-brown with a strong middorsal red tubercle over the 

 third abdominal prolegs with a red cross band just behind
