Maxim, do you think rufipes? I, of course, understand that rufipes also lives in Wed.Asia, but somehow it's all strange And lugens-easily, of course, but I wouldn't vouch for it )

So it has a side corner of the platband healthy even when viewed from the side, acrossusny, it is exactly brown (light? I didn't think it was abnormal), obviously large. About the sand from the Astrakhan region somehow attracted attention, yes. But this is no longer anything, like. And lugens-really, easily, it's not caspius, not circumcinctus (and it's a little late for the latter). Of course, it is not necessary to vouch for the picture, but the idea about lugens is, in my opinion, the most plausible of all theoretically possible candidates (nigriventris, longeciliatus). The head is almost smooth, again.

Hello! please tell me, what kind of leaf beetle is this?
Chrysolina graminis or chrysolina herbacea? I'm already confused." And what is the difference between these types?

If you put both views side by side, you will be able to see the external differences. It is not very easy to formulate the differences, as I will be able to. Graminis has a much coarser sculpture, including on the pronotum, where longitudinal depressions are marked on the sides of the base. It is also on average larger, often has longitudinal colored blurred stripes on the sides of the elytra and along the suture (not always, in dry beetles they sometimes turn blue or disappear) and does not live on mint.
Cysolina herbacea is much smoother, with no roughly dotted indentations on the sides of the pronotum base. There are quite a lot of defining keys, and take a look at them for formal features. Your beetles in the picture seem to me graminis.
