two pairs of prolegs are very light, almost cream color, outside flanked 

 by very dark brown. 



On ]\Iay 26th larvae of Catocala luciana after 4th (?) moult, some- 

 what lighter color than before the moult, but taking on a grayish tinge, 

 a day or two later. The hump over the third pair of prolegs red brown. 

 Head, the same color. Lateral setae short but thick. The larvae at this 

 time were nearly two inches long. 



May 29th. Grown larvae of Catocala luciana two and one-half inches 

 long, light brown, with a reddish tint. Tubercles deeper red brown. 

 Head, as in cara with yellow lobes above and a lateral brown facial 

 dash. The true legs, body color. Prolegs slightly browner. The body 

 indistinctly lined longitudinally. Lateral setae very short. 



There are two colors that prevailed among the larvae, one 

 light reddish brown and the other slightly bluer or with a 

 leaden tint. 



It is proper to state in this connection that the chrysalids 

 from these larvae gave two types of imagoes, possibly distinct 

 specifically. The eggs were laid by two females and sent to 

 the senior author, the autumn before, from Denver, Colorado. 



At the time the senior author visited the locality on the 

 Platte River and took numbers of the moths under the wagon 

 bridge over that stream, none other than luciana were seen 

 among the scores that were frightened from their hiding 

 places. It was hardly more than a week from that time that 

 Mr. Dulany obtained the females that laid the eggs mentioned 

 above. 



On June ist there is this record on luciana. Larvae very 

 light gray with a small, somewhat darker cross hump over the 

 third abdominal prolegs. The darker larvae remind one of 

 parta caterpillars, the lighter ones of concumbens. The first 

 larva began spinning under paper on the above date, 25 days 

 from hatching. 



The larvae of C. luciana spun from the ist to the 6th of 

 June while the retecta began on the 5th. 



The pupae of Catocala luciana gave the first imagoes of that 

 species on July 3d. Both were males. This is nearly a month 

 earlier than the species appears in Colorado. The chrysalis 

 period of this moth is one month as the lan-ae of these two 

 moths pupated in the first week of June. 



The first female imagoes of C. luciuna emerged on the 6th 

 of July.
