646 THE BUTTERFLIES OF NEW ENGLAND. 



P. tharos morpheus ; the prevailing tint of the fore wings is the same pale 

 greenish ochraceous that suffuses the hind wings, the orange or fulvous 

 tints occurring mainly in the reverse of the inner intra-niesial band, and of 

 the spot at the extremity of the cell, and in a transverse belt in the middle 

 of the outer half of the wings ; the black markings of the fore wings 

 are much heavier and more distinct than they ever are in P. tharos. On 

 the hind wings one uniform tint pervades the whole under surface ; the 

 transverse lines are very faint, obscurer than the palest tharos, and the 

 large marginal patch in the middle of the wing, so conspicuous a feature 

 on the wings of tharos, is entirely wanting. 



Disttlbution (22:4). Our information concerning this butterfly is 

 extremely meagre. Though recorded by Edwards from Ohio, it has rarely 

 been found far from the Atlantic coast, and only in the AUeghanian fauna, 

 unless the very doubtful reference by Couper of specimens from Anticosti 

 and southern Labrador to this species is verified. (The identification 

 was by Strecker.) In Virginia and West Virginia it is not common 

 (Edwards), not uncommon in Pennsylvania (Reakirt), and has been 

 found in southern New York (Gracf), and about Albany and Sco- 

 harie (Lintner), as well as in Hamilton, Ont. (Johnson fide Fletcher). 

 The only other states from which we have a record of its capture are Mary- 

 land (Edwards) and New Jersey (Aaron). Its home is therefore east of 

 the Appalachians, from central New York to Virginia. 



In New England I have taken it at the White Mountains. 



Life history. Its earlier stages are totally unknown, but they will 

 doubtless be found to agree very closely with those of P. tharos. I failed 

 to obtain eggs from a female enclosed on Aster novae angliae. From the 

 recorded times of flight of the imago, however, we may glean a little. In 

 the south it appears toward the last of May, becoming abundant by the 

 very end of the month. In Albany Co., N. Y., it appears by the last 

 day of ]\Iay, reaches its greatest abundance by the 7th of June, and was 

 last seen by Mr. Lintner on the 2 2d of the same month. My captures at 

 the White Mountains were on the 7th of June. No mention has been 

 made of a second brood, though it doubtless occurs. 



Desiderata. While the life history of this butterfly is unknown, it is 

 not worth while to record other lack of information. It remains indeed to 

 be proved, as suggested by Edwards, whether it is not simply a varietal 

 form of P. tharos marcia, to which, rather than to P. tharos morpheus, 

 its time of flight would consign it. This seems altogether probable, but 

 only careful breeding will show the facts in the case.
