ussuriensis being at my disposal wholly corresp<strong>on</strong>d to <strong>the</strong> descripti<strong>on</strong> of<br />
Ch. aeruginosa sensu WEISE (1887) and <strong>the</strong> original descripti<strong>on</strong> of Ch. pubitarsis.<br />
I had no possibility to borrow <strong>the</strong> type of Ch. pubitarsis. However, I examined<br />
<strong>on</strong>e female, which was determined by Dr. J. BECHYNÉ as Ch. pubitarsis. I found<br />
this specimen to be c<strong>on</strong>specific <strong>with</strong> Ch. difficilis ussuriensis. Therefore, I regard<br />
Ch. pubitarsis as a new junior syn<strong>on</strong>ym of Ch. difficilis ussuriensis.<br />
MATERIAL<br />
Ch. difficilis ussuriensis: China: „Mandschurei Weischache Mai 1938”,<br />
„<strong>Chrysolina</strong> pubitarsis m. J. BECHYNÉ det., 1950”: 1 female. Russia: Primorski<br />
Krai: Kamenushka, 17.8.1987: 1 female, I. NETUZHILIN leg.; S. Sikhote Alin,<br />
Promyslovka, 7.9.: 1 male, PERELESHINA leg.<br />
37. According to <strong>the</strong> original descripti<strong>on</strong> (BECHYNÉ 1952), <strong>the</strong> subspecies Ch.<br />
nikinoja exgeminata differs from <strong>the</strong> nominotypical <strong>on</strong>e in <strong>the</strong> following characters:<br />
“Die Oberseite ... ist metallisch violett, sehr stark glanzend, Korperform<br />
mehr langlich. Die Punktierung des Halsschildes ist feiner (nur so stark als auf<br />
den Zwischenraumen der Flugeldecken) aber die sekundare (in Reihen gestellte)<br />
Elytralpunktierung ist grober als bei der Stammform”. I examined <strong>the</strong> types of both<br />
Ch. n. nikinoja and Ch. n. exgeminata (Fig. 17) and found that <strong>the</strong>y represented <strong>the</strong><br />
same tax<strong>on</strong>.<br />

38. I examined <strong>the</strong> type of Ch. nikinoja (Fig. 16) and available specimens of<br />
Ch. difficilis yezoensis (type of Ch. yezoensis studied by TAKIZAWA 1970) and<br />
decided that <strong>the</strong>y are c<strong>on</strong>specific. Therefore, Ch. nikinoja is a new junior syn<strong>on</strong>ym<br />
of Ch. difficilis yezoensis.<br />
