vae were over half an inch long, dark gray with fine longitudinal 

 light lines. A strong hump over the 5th abdominal segment. Head 

 large with facial white lines. Face flat, slightly lobed above. The top 

 of the abdominal hump black. 



The third moult occurred on the I2th and I3th and the larvae were 

 about an inch long, dirty gray with a big head, bearing a pair of 

 blunt-like tubercles above with yellow lunules in front. Body tuber- 

 cles yellow-brown. A sharp dark brown hump with a yellow point 

 over the 3rd pair of prolegs. A pair of strong tubercles over the 

 7th abdominal segment. 



After the fourth moult on the :6th, the caterpillars were from i l / 2 

 to 1^4 inches long, light gray with a yellowish tinge. Tubercles white 

 with black tips. Head large, flat in front, lobed above with yellowish 

 tips to the lobes and heavy black lines behind the lobes. Head a lit- 

 tle lighter in front than the rest of the body. A pale brownish band 

 just behind the hump over the 3rd prolegs. The hump is hardly dis- 

 tinguishable from the body color except it has a white top. The pair 

 of tubercles over the 8th abdominal segment have black tips and are 

 strong. The under side of the body light with round black spots. 



By May 21 st, the larvae of aholibah were full grown and less than 

 three inches long, thick heavy caterpillars, gray with a brownish 

 tinge, black dots in encircling irregular white patches. Tubercles 

 black in a white basal spot. The cross band over the 3rd pair of pro- 

 legs light yellow brown. Hump with dark base and yellow tip. The 

 lateral row of setae rather short. The bristles on the top of the 

 tubercle short. Head bi-lobed above with a broad black band behind 

 the lobes. The true legs reddish brown with cross black bands at the 

 segments. Spiracles black with an encircling white patch or line. A 

 cross patch of lighter than body color over the first abdominal seg- 

 ment. The under side of the body pale or white with a midrow of 

 large black spots in red-brown or yellow-brown patches. 



All of the coloradensis larvae died after the fourth moult and the 

 first of the aholibah began spinning on the 23rd. From a number of 

 chrysalids of aholibah but one imago emerged, a fine male, on June 

 2pth, with a pupal period of over five weeks. The chrysalids were 

 killed, perhaps, by heat. The larvae of both aholibah and coloraden- 

 sis fed on bur oak. 



Catocala faustina and var verecunda. 



Eggs of Catocala faustina and variety verecunda hatched on the 

 4th and 5th of May. The larva of verecunda at the first moult on the 

 afternoon of the 7th was one-third of an inch long, light color, witli 

 almost white dorsum. Head light chestnut. Larva slender. 



Just before the second moult on the roth, the larva of verecunda
