§6 MELITTA. (<*. c.) 



head I always entertained considerable doubts, and 

 when I consulted the authentic specimen of that 

 insect still preserved in the Linnean cabinet, I 

 found that I was not mistaken, the true A. helvola 

 being very distinct, as will appear hereafter. The 

 definitions of the Zoologia Danica are so short, and 

 unaccompanied by longer descriptions, that it is 

 not always easy to say what insect is intended by 

 them, but I think in my reference to that work 

 upon this occasion 1 am not mistaken. Christius 

 gives a figure of our insect as the Andrena hce- 

 morrhoklalis of Fabricius, which, however, is very 

 different, it will be described in the course of this 

 w^ork. M. albicans is one of our most commori
