GENUS I. BUTTERFLIES. 



SEC. I. SP. XIII. APRIL FRITILLARY. 



PI. 13. 



Euphrofyne. Linnœus. 



Pearl Border Fricillary. Harris. 



This butterfly is very plentiful in all our woods, and is the flrft of the 

 fritillaries that makes its appearance on the wing in the fpring of the year. I 

 have feen it flying as early as the 1 2th of April. The caterpillar is un- 

 known ; but from the clofe refemblance of the butterfly to others of this numer- 

 ous and fimilar, yet diftinér. clafs of flies, we may reafonably conclude, that it is 

 hairy and fpined ; and by being out fo early on the wing in the fpring, we may 

 fuppofe the caterpillar changes to a chryfalis in the autumn, and in that ftate 

 paffes the winter. 



The upper fide of the butterfly is reprefented at fig. 1 ; and it is delineated 

 at reft, with the wings erect, to fhew the under parts, at fig. 2. 



SP. XIV. MAY FRITILLARY. 



Euphrafia. Limiaus. 



Small Pearl Border Fritillary. Harris. 



This butterfly is to be taken in woods about the middle of May, flying with 

 the above defcribed ; and indeed they are fo like each other, that a perfon not 

 well acquainted with them would fuppofe them to be the fame fpecies. The 

 difference of the markings on the upper fide is fcarcely difcernible : however 

 the under wing on the under fide is diftinftly different, fo that there is not in 

 reality any doubt of their being difbindt fpecies. 



The caterpillar of this fpecies is likewife unknown. I have reprefented the 

 upper fide of this butterfly at fig. 3 ; and the under fide at fig. 4. 



Thefe are common infects, and both fpecies of flies may be eafily taken, 

 when feeding on the different flowers that bloom at the time they are on the wing.
