I could buy (for 29.81 € at Amazon.com , shipping included) a bad reprint of this year 1818.

Ciao,
n° 2981 (♀) & n° 2982 (♂) at an altitude of about 940 m. in Cne : Le-Petit-Abergement (Dépt. Ain - France) - 05.06.1995

♂ & ♀ captured at the same time and at the same place, posed on inflorescences of white Umbelliferae.

Although not copulating I think that it is about the same species .

One uses the keys (which I already sent to the forum) here after :
download/file.php?id=47394&mode=view and download/file.php?id=47396&mode=view
One finds that it is a Tenthredininae .
According to Benson p.109/112 : one is in the presence of a tenthredopsis, because the 2 insects have :

The 1st tergite does not have a medial furrow (which I could not photo because of the poor quality of my camera)

It is observed in addition :
- The forms of the clypeus (to see my photos).
- The drawings on the abdomens are caracteritic.
According to Berland p. 143 it is T. tesselata
If one had used the keys of Blank & Ritzau, one would have arrived at the same result.

Thus :
Tenthredopsis tesselata (Klug 1817) (♂ & ♀)
Vive anche in Italia (to see : Fauna europaea)
..... OK ?

Saluti.
