NYMPIIALIXAE: EUPTOIETA CLAT'DTA. 527 



Mv. Edwards thinks that the caterpillars of tlic autumn brood probably 

 hibernate when half grown ; caterpillars, however, fed on passion flower 

 (their favorite food), all grew rapidly and went through all the changes 

 to butterfly before December ; while those fed on violet only passed the 

 second moult by the end of October, and all finally died, the last just as it 

 was about to pupate, on March 22. 



In New England the few specimens captured have generally been taken 

 in the first half of August. ^h\ Thaxter's Kittery specimen was taken as 

 late as September 1, and ^Nlr. Sprague took a fi'csh female on Septem- 

 ber 7 at ]\Ialden, besides fresh males on the 17th and 27th of July. Jt 

 would seem as if these were all members of a single brood. When mem- 

 bers of an early May or June brood are found, we may more confidently 

 consider it really indigenous to eastern New Enoland. 



The butterflies frequent fields, especially lowlands, and are very partial 

 to flowers, — according to lieakirt, to Helianthi ; this author adds that it is 

 ''of very cpiick but not high flight"; and Doubleday says that "it is an 

 insect of rapid flight, frequenting open places, especially near rivers, 

 delighting to sit on the dry sand, rising instantly if approached, and very 

 difficult to follow even with the eye." 



Desiderata. The life history of this insect is far too imperfectly 

 known, the above account being largely conjectural or founded on very 

 meagre data. The number of broods, both north and south, might be 

 easily determined by local observers, and the mode or modes in which hiber- 

 nation is effected especially need attention. Particular attention should 

 be given to any signs of periodic lethargy in the caterpillar. The habits, 

 postures and special characteristics of the flight of the butterfly should be 

 studied, and any parasites of the early stages are quite unknown. It is 

 hardly to be expected that much information will be gained in Ncav Eng- 

 land ; it must come from more southern observers.
