ed by or flanked behind by, rather, a cross band of deep yellow. 

 Ventral side reddish with the central black spots (almost pink- 

 ish below). The tubercles over the 8th abdominal segment 

 rather strong, flanked behind by a strong cross line of black. 

 The lateral setae very short, almost absent. After the fifth (?) 

 moult, the larva of conciunbens has the same colors and marks 

 as after the fourth moult, except that the body color is a shade 

 lighter. Length from two to two and a fourth inches. 



On the 23d of June, ants killed the last jar of conciunbens 

 larvae. Grown larvae of concnmbcns received from the junior 

 author were from two and a half to three inches long, brown 

 with faint reddish tinge. Tubercles deep red-brown. A cross 

 band of light red-brown over the back half of the 5th abdomi- 

 nal segment. The cross elliptical hump over the 5th abdominal 

 segment is hardly noticeable, reddish yellow with a darker basal 

 girdle. The two dorsal tubercles on the 8th abdominal seg- 

 ment scarcely stronger than the rest but with a cross line of 

 black for a back boundary. True legs reddish yellow. Pro- 

 legs, body color. Head, body color, flattened as in car a with a 

 lateral boundary line of black from the mouth around to the 

 mouth, not broken above. The horn-like lobes of the head 

 above orange yellow. Ventral side of the body, beautiful pink 

 with black central spots. Bristles not long. Lateral fringe of 

 short setae. The junior author had better luck with her larvae 

 of concnmbcns, securing pupae and imagoes, feeding her lar- 

 vae on broad leaf willow while the senior author fed his brood 

 on black willow. Four chrvsalids of conciunbens sent bv mail 



J 



from Vinton, Iowa, to Louisiana, Mo., produced as many beau- 

 tiful imagoes while chrysalids of ainatri.r, rclicta, and piatri.r 

 either perished on the road or died later, but the weather was 

 intensely warm when these pupae started through the mails. 

 Among a number of pupae of ncogama, sent under similar 

 circumstances, three produced moths. 



On the 25th day of May the eggs of ainatri.r began to hatch. 

 The young larva is light brown with lighter longitudinal streaks. 

 Head, chestnut or light brown. True and pro-legs, colored as 

 the body. Much darker than most other willow feeders at this 

 stage, that is, before first moult.
