Note. — From the above enumeration it will be seen that the forms of C. ferrugineus 

 and its allies breed on various plants of different families, but never on Cucurbitaceae ; 

 while C. cucurbitae and its allies feed only on plants of that family. The polyphagous 

 species, like C. ferrugineus {s. I.) and C. cucurbitae, are very variable in their characters. 

 Only species or forms of theferrugineus-grouip are attracted by oil of citronella.
