LEPIDOPTERA NYMPHALIDAE PHYCIODES MATA. 763 



worn were taken early in June, so it is probable that the species appears 

 about the first of Ma) r on the plains, though somewhat later in the mount- 

 ains. None were seen in the neighborhood of the South Park at above 



8,000 feet. 



PHYCIODES THAEOS, Boisd. 



Phyeiodcs Tharos, HARRIS, Insects Injurious to Vegetation. 



P. Tharos was found quite abundantly on Turkey Creek with Carlota 

 and Nycteis. Like the latter, these are slightly darker than eastern speci- 

 mens, but otherwise quite indistinguishable. 



PHYCIODES MAECIA, Eclw. 

 Phyciodes Ularcia, EDW., Trans. Atn. Ent. Soc., 1868. 



With Tharos were also found one or two specimens of Marcia, in no 

 wise differing from types of the species. It was also taken by the expedi- 

 tion in 1871, but the precise locality is not given. 



PHYCIODES PALLIDA, Edw. 

 Phyciodes Pallida, EDW., Proc. Ent. Soc. Phila., 18C4. 



Brought by the expedition from Southern Utah. One specimen was 

 taken in Colorado, probably at a low elevation. 



PHYCIODES MATA, Eeakirt. 



Phyciodes Mata, EEAKIRT., Proc. Ent. Soc. Phila., 1867. STRECKER, Illustrations 

 Lepidoptera, 1874. 



The type of this species was collected in Colorado ; since then none 

 have been seen. The original description states that the specimen was 

 bleached and faded. This is contradicted by Mr. Strecker in No. 8 of his 

 "Illustrations", because the specimen had not been exposed to light after 

 its capture ; but I have taken several specimens of a Phyciodes near Salt 

 Lake City, which had certainly been bleached by the action of the weather, 

 and it seems to me probable from the figure and description that P. Mata is 

 a faded specimen of P. PalUda, having the pale bands slightly more pro- 

 nounced than in the usual type. This manner of variation is well exempli- 

 fied in P. Camillas, the females of which sometimes have the usual yellow 

 median and marginal bands pure white below (var. Emissa, Edwards).
