Eight species are recognized as belonging 

 to this genus. M. Mulsant has divided the 

 members into various genera, not altogether 

 happily, as he has grouped species together 

 not particularly similar, and separated others that were: viz., H. cos and K lutitice 

 in Calligenia, leaving H. honapartii in Helianthea, whereas in every respect this 

 last is closely allied to H. cos, which has a luminous rump, contrary to the species 

 of Callixjenia as restricted by M. Mulsant.
