The above insect affords sufficient characters for 

 separating it from Monsieur Latreille's genus Rhiso- 

 trogus, under which name (according to the Baron 

 De Jean's Catalogues) various species are thrown 

 together which require further subdivision. To 

 this genus belong Mel. sestiva, aprilina and rufescens 

 with many others.
