PLATE CCCCXXX, 



LIBELLULA BOLTONII. 



BOLTON's DRAGON-FLY. 



NEUROPTERA. 



, GENERIC CHARACTER. 



Mouth armed with more than two jaws : lip trifid : antennae 

 fhorter than the thorax, very thin and filiform: wings expanded: 

 tail of the male furniflied with a furcated procefs. 



SPECIFIC CHARACTER. 



Libellula Boltonii: wings hyaline: body elongated, black, 

 with a larger interrupted yellow band acrofs the 

 middle, and a fmaller near the tip of each feg- 

 ment. 



This fine and noble fpecies of Libellula appears to be unknown 

 to any of the entomological writers we are acquainted with. The 

 fpecimen from which our figure in the annexed plate is taken, was 

 difcovered in Yorkfhire fome years ago by Mr. Bolton, and commu- 

 nicated to Mr. Drury, in whofe cabinet it has remained unnoticed 

 till the prefent time. We believe this fpecimen to be unique, or at 

 leaft we have never ken an other. It is a beautiful, large, and in- 

 terefting fpecies, and pofi'efles characters fo extremely different from 

 any of the known fpecies of its genus, that it cannot ealily be mil- 

 taken. We name it Boltonii, in compliment to Mr. Bolton, the 

 gentleman to whom we are indebted for its difcovery.
