DISTRIBUTION. In the Eastern Palearctic, from the Irkutsk region and Mongolia in the west to Kamchatka in the east, and from the Magadan region in the north to Primorye and

Hokkaido in the south. Previously, it was known in Sakhalin from Dudino and Novoaleksandrovsk only (Špatenka & Gorbunov, 1992; Gorbunov & Tshistjakov, 1995) .

HOST PLANTS. The larvae live in places of damage to the bark of trunks or branches of various Salix spp. (Salicaceae) . Salix udensis Trautv. et C.A. Mey. should be considered the most likely host plant on Sakhalin.

SEXUAL ACTIVITY. Although the females were active and were collected on Eupatorium chinense L. ( Asteraceae ) flowers, none of the males were attracted to any of the pheromone lures used.

REMARKS. Here it is appropriate to point out the fact that the pheromone lure for Synan-

tedon formicaeformis available in this pool was successfully used to collect S. formicaeformis in the Republic of Crimea and Moscow region. Perhaps this should be considered one of the arguments in favor of the opinion on the species status of S. herzi . I have always considered and still consider S. herzi to be a good species, and not a subspecies or even a junior synonym of S. formicaeformis .
