low. The ventral surface is cream-yellow with large black 

 spots. Head, light yellow with fine longitudial lines, gray or 

 black. The larvae of innubens are the hardiest of the hardy, 

 and while there were no deaths in the brood, there wasn't a 

 scintillans among the imagoes. The chrysalids gave moths 

 from June 2/th to July 1st. 



Individuals of this species are the most abundant Catocala 

 moths in the forests of Pike County, Missouri. The food plant 

 of the larva is honey locust. 



The larvae of palaeogama began hatching on the I5th of 

 May and were dark blue or dove color with white legs, white 

 pro-legs and white ventral surface. The head not quite as 

 dark as the body color. Longitudinal lines hardly discernible. 

 After the first moult these larvae are black with indistinct longi- 

 tudinal lighter lines. Head black. Both true and pro-legs 

 light, almost white. Little or no change in these larvae after 

 the first and second moults save an increase in size and a little 

 lightening of the ground color. After the third moult, general 

 color bluish-gray with black head, lined with fine white marks, 

 dark thoracic segments, dark dorsal patch on both 5th and 6th 

 abdominal segments and dark sides to the 8th and Qth segments 

 and dark loth segment. The 3d and 4th pro-legs black, the ist 

 and 2(1, gray. True legs dark brown. Tubercles black. A 

 slight hump over the 5th abdominal segment. After the fourth 

 moult, the larva entirely loses its bluish color and becomes dark 

 gray with the three thoracic segments, a cross band between the 

 5th and 6th abdominal segments and the 8th, Qth, and loth ab- 

 dominal segments black. Head gray, streaked with dark 

 brown. True legs, dirty yellow. Pro-legs, of the general body 

 color. A slight cross ridge over the 5th abdominal segment and 

 prominent black tubercles over the 8th abdominal segment. 

 Tubercles black. In a few hours after the moult they resume 

 their bluish-white color. After the fifth (?) moult, the palaeo- 

 gama larva is light red-brown over the abdominal region to the 

 5th segment, where a cross black band covers half of the 5th 

 and half of the 6th segments. The thoracic segments, as well 

 as the 8th, Qth, and loth abdominal segments, are dark brown,
