22 - Cassida rubiginosa
29 - Hydrothassa marginella

22 -- No, it's Cassida sanguinosa leucanthemi. Moreover, I am inclined to the latter option, but not more than 60 by 40 in%. The" correct " Cassida rubiginosa looks like this: http://www.eakringbirds.com/eakringbirds2/...toisebeetle.htm . All the pictures in Google can not be trusted, as I managed to skim through-a lot of inaccurate opr.
Comrades who shoot the shield-bearer alive and not only, please turn the beetle over and take a picture of it also from below - the accuracy of the definition will be higher. In the same rubiginosa, the thighs are black, and in similar species - light.

29 -- Prasocuris marginella, according to modern nomenclature. I would not consider Hydrothassa even as a subgenus - there are no rank-related differences between Hydrothassa and Prasocuris (other than body shape). This is similar to the genus Mecinus (Ilya will understand).

Good evening, can you help me deal with the Cassids? Krasnoyarsk Territory is everything.
1. Cassida subreticulata like. The claws are small and hidden. There are depressions at the scutellum and in the middle of the elytra. Krasnoyarsk, polyana kosheniye
[attachmentid ()=150987]
[attachmentid()=150988]
[attachmentid()=150989]
2. Similar but confused by the stronger punctuation of the elytra and less rounded body. The claws are also very small. Indentations on the elytra are not visible near Krasnoyarsk, also when mowing in a meadow
[attachmentid ()=150990]
[attachmentid()=150991]
3. similar to sanguinosa, confusing clear rows of dots. They are quite poorly visible on the shiny surface. The suture and base of the elytra are reddish. Upper lip with a short but deep notch.
[attachmentid()=150992]
[attachmentid()=150993]
[attachmentid()=150994]

Eugene, in the" Google search " accidentally came across your post (p. 330), it seems to be unanswered. If you need more, I define:

1 -- Cassida subreticulata.
2 -- Cassida azurea. This is my favorite shchitonoska (live beetles are very beautiful - http://www.pinterest.com/pin/351984527096529544/ I remember how in the Carpathians (height 500-700 m, Rakhovsky district) almost 7 years ago I first found it and went for three hours to collect it in the rain on smolki, until the joy of the discoverer faded

a little . On the plains - very rarely, on dry, sedimentary slopes with calcareous soils (in EC).
3 -- Cassida denticollis should be there, but there are signs that I'm a little worried about. In any case, only one of the trans-palearcts (Europe-Siberia) can be found.

thank you, yes, these leaf-eaters were left to me without definitions. But now there is nothing to compare it with, since all the material is being determined by specialists

.
Cassida azurea, yes, the beetle's upper body changes a lot when it dies. But in addition to these views, there was a little more interesting, so I'm looking forward to getting the material back.
By the way, Legalov sent a few beetles, including "our magdalisovs", he has beetles, but he has not yet taken them up.
