Var. a. Thorax rufous, immaculate ; head black. 



This species I might have referred to C. furcatus of Fabr., 

 had he not quoted for lineola a figure of Olivier's which agrees 

 very well with this insect ; an agreement to which, when com- 

 bined with the accompanying description, no doubt can be 

 attached. 



Is not furcatus the same insect? I should suppose the species 

 named comma to be also closely allied to it. 



[Belongs to Agonoderus. — Lec]
