At first I mistook this beautiful insect for JB. equestris Fabr. ; 

 but the terms — Corpus aneum — sterno parum porrecto — Elytra 

 punctorwn duorum par, by no means agreed with it : and when I 

 further compared it with Olivier's J3. hcEmorrhoidalis, to which Fa- 

 bricius refers as synonymous with his B. equestris, I was fully con- 

 vinced that they were distinct species ; since from Olivier's figure 

 it appears that B. hcemorrhoidalis is little more than half the size 

 of B.jucunda; and in the former the three last ventral segments 

 of the abdomen are red, whereas in the latter they are green*.
