Identification of beetles (Coleoptera)

all - Moscow region, Serpukhov district, Novoki-Begichevo village

Good time to all!
Tell me who knows, is it someone from Rutelinae?
Primorsky Krai, Yakovlevka, June. 10 mm.

Apogonia cupreoviridis Kolbe, 1886 (=nigroolivacea Heyden, 1886)

Help us identify the abscesses. June of this year, Saratov region, steppe near the village of Apalikha (Khvalynsky district)

You can say what kind of leaf eater:

is there a rear view?

is there a rear view? or other prsp angles? it doesn't look like a populi, most likely tremula or saliceti

Roma in my opinion can be Chrysolina polita

Aulacobaris janthina ? Krasnoyarsk, 3 mm.

In my opinion, it's a little short and a little shallow, and you can't see any scales, but I don't see any other options (well, except for sp. nov. of course)
In any case, janthina is almost the only aulacobaris that reaches the Kemerovo region, and it develops on ruderal weeds, especially on cardaria draba and gulyavniki. There is also kaszabi described from Lake Baikal, but it is close to lepidii

Krasnoyarsk, 5 mm. Otyorhynchus sp
is somewhat similar to O. velutinus, but the pronotum is clearly smaller and narrower than the elytra. Elytra are wider. The hairs on the elytra are shorter and thicker, visible both from the side and from above. There is a noticeable keel in the middle of the head tube. Front thighs with a wide elevation, on which there are 3 teeth, the innermost one is larger than the rest.
1. right O. velutinus

Well, it's easier to shoot yourself here. But if you want to spend an hour or two, you can try to search for Arnoldi's work "Weevils of the genus Otiorrhynchus (Curculionidae) of the fauna of Mongolia and neighboring regions of the USSR". But even this does not give a 100% guarantee, especially since the work is already outdated, and not the entire region is covered in it.

I drop it to Legalov then

isn't Cassida rubiginosa Muller, 1776 ?

But this one ?Can I tell Chrysoline something?"
SV Macedonia (Balkans), June, 13 mm

most likely, this is Timarcha, but I won't say the type, because I don't know recently received similar ones from Spain, but I haven't figured it out yet. beetles are wingless and inhabit warheads in arid zones - this leads to speciation and confusion in taxonomy  

is everything wrong with my abscesses?
