It is possible that you have seen yellow G. semipunctatum specimens. But have you ever seen a light-yellow and black colored G. italicum specimen?

*G. lineatum lineatum is only known from North Africa! What you mean with G. lineatum actually G. italicum italicum.

The first is probably not Graphosoma melanoxanthum.

I was trying to say that G. italicum is never light-yellow colored. Such light yellow coloration with continuous black lines on the pronotum is unique to G. melaxanthum. Also the femora and tibiae of G. italicum italicum is black which is almost totally yellow in G. melaxanthum. So it is %100 sure that these 3 specimens belong to Graphosoma melaxanthum.

Yes, the first one in this link is G. rubrolineatum, species of Far East.
