Identification of beetles (Coleoptera)

Define, plizz.
What kind of rhino is this?
Caucasus.

     
This is Temnorhynchus.
And where exactly in the Caucasus is it collected?

Unfortunately, I don't know exactly where I got it from. Isn't that our beast?"

I have a plug with abscess

Volgograd region, 13 km W from st-tsy Nizhne-Chirskaya, the bank of the dam
on the "green" I get either sibirica or geminata
If this is a "low smooth keel", then it should be sibirica?

in my opinion, this is Hycleus, not Mylabris

Is this such a small Leptura thoracica or did I go in the wrong direction?

Paophilus albilaterus (Faust, 1882)

Ilya, Ilya, I haven't seen you so emotional in a long time. What's wrong with this bug?
So I did not climb these steep slopes for nothing. )))

a good beetle, I would like to add it to the collection, spread it out in a normal way ...

According to the area that you have indicated, Krasnoyarsk remains to the east, so this is a new point for the species?
I have 5-6 beetles, in connection with catches almost every day, molded everything on the dies in different angles, did not particularly look at the correctness of spreading. I'll keep that in mind for you if I'm in the area next year.

1-Chrysolina sp
2-Adoxus obscurus
3-Byrrhus sp

Help me determine it.

Dominican Republic.

Ilya, here is the area where these elephants were mowed down. These are steep rocky slopes with thickets of acacia trees.

Elafidions, of course, are not the easiest company for us,on the other hand.
The former I would venture to call Elaphidion splendidum Fish., 1932,
and the latter E. conspersum Newman, 1842.

he lives on an acacia tree.

and there are 2 types of them

I don't really understand how they differ, and I might have translated something wrong (German).
But it seems to be just albilaterus ...

Yes, thanks... I'd like to feel your ptochuses again...

MO, Zheleznodorozhny, on light
3. Tomicus minor?

  
But what T. minor did on the birch tree is not entirely clear to me. Here he prefers common pine
