dominal segment is a slight ridge like elevation with a black 

 line behind it. The top of the ist thoracic segment is dark. A 

 row of stout setae are along each side. Body dots minute, dark. 



After fourth moult, the larva is yellowish gray with black or 

 dark brown head, less flattened than at third moult, with bright 

 yellow lunules at the upper lobes. The top of the ist thoracic 

 and 2d abdominal segments darker than the body color. A 

 cross band of dark brown, almost black, envelops the hum}) 

 over the 5th abdominal segment and a cross streak of black be- 

 hind the double dorsal tubercle over the 8th abdominal seg- 

 ment. True legs, reddish gray. Pro-legs, body color. Tuber- 

 cles not noticeable. At this stage the larva is much like that of 

 Catocala fraxini. There is a lateral fringe or row of short 

 setae. Later, probably after the fifth moult, or rather, at the 

 fifth moult, is one and a half inches long, whitish yellow. Head 

 black, large and much as in C. fraxini with yellow-white lunules 

 at the lobes above. True and pro-legs, body color. A slight 

 hump over the 5th segment, with a small yellow-brown spot on 

 top, enveloped in a cross band of dark, a black line crossing the 

 8th abdominal segment as a shade line behind the two dorsal 

 tubercles which are not strong. 



The rest of the body tubercles cream color and inconspicu- 

 ous. A dark shade line crosses the front of the 2d abdominal 

 segments, a dimmer one at the front of the 3d abdominal seg- 

 ment. Two small dark spots are on the top of the 7th abdomi- 

 nal segment. The front of the head, that is about the mouth, 

 is grayer than above. Tubercles darker than the body color. 

 Row of short lateral setae. Full grown larvae two and one- 

 fourth inches long and the first began to spin on the 22d of 

 June. 



The full grown larva is greenish gray with an indistinct 

 double V of dark dots on the tops of the ist and 2d abdominal 

 segments and a slight dark patch of dots on the side of the ist 

 thoracic segment. A cross band of black, invaded by the body 

 color, mid-dorsal and laterally, crosses the back of the 5th and 

 front of the 6th abdominal segments, extending onto the third 

 pro-leg. A slight mid-dorsal cross black line on the 7th ab-
