June 14th. Full grown larvae of C. vidua are three inches long, ashen 

 gray with cream-colored tubercles. A row of lateral setae. The body 

 covered by minute black dots that more or less arrange themselves in 

 longitudinal lines that outline indistinct longitudinal bands, thirteen in 

 number. A dark cross band over the dorsum between the third and 

 fourth pairs of prolegs. The true, as well as the prolegs, are body 

 color. Head, light gray with red brown irregular lines. A slight black 

 dash either side of the mouth. Some specimens have a slight reddish 

 tint while others are slightly darker gray. All larvae before the last 

 moult are reddish. 



On the 15th of June the first vidua larva began to spin. 



From overcrowding, disease carried off a number of the 

 larvae of vidua and pernyi. 



The larvae of both vidua and retecta likewise spin their 

 cocoons between leaves and the pupae, as in other species, are 

 brown, covered by a white pruinescence. 



The first imago of Catocala vidua emerged on July 20th, a 

 full month after pupation, allowing five days between spinning 

 and pupation. 



On May 26th the larvae of Catocala retecta were about two 

 inches long. 



On June ist, about two and three-fourth inches long, dark uniform 

 gray with a broad, illy-defined cross, dark brown band between the 3rd 

 and 4th abdominal segments. These larvae hatched May 7th. 



June 8th. The larvae of C. retecta fully grown, measuring two and 

 three-fourth inches, light gray with longitudinal lines of wavy dots and 

 dashes. The cross band between the third and fourth pairs of prolegs. 

 somewhat darker than the general body color. The tubercles cream 

 color. Lateral setae present. The head has the color of the rest of 

 the body, with black cheek dash. The logitudinal dark lines form nar- 

 row bands. 



A larva of Catocala ininuta, found feeding on honey locust 

 by the junior author, was one and three-eighths inches long on 



June 6th, dark brown with light gray patches. Head, small, gray, flat. 

 A slight hump over the first abdominal segment with a minute black 

 dot on each side. The hump is gray. There is a cross hump between 

 the second and third abdominal prolegs on the dorsum, gray in front 

 and darker behind with a small white crest. There is a lateral row of 

 short setae. A sharp crest is over the eighth abdominal segment as in 

 other Catocala larvae. The ventral side is pale green with a row of 

 medial black spots. 



The larva of Catocala minufa spun on June 7th and the 

 pupa gave an imago on June 30th.
