W027 anm.; Vi, 0.14 mm:; spur, 0:14>mm..- Total length of

Cladobius lanthanie (Pass) Koch (Henrich). 
Henrich lsts Aphis lantane Koch under the above name 
and refers it to Passerini. The writer has never seen this 
species, but from the description given by Koch and his figures 
I am of the opinion that 1t does not belong here. 
He also records a species under the name of Cladobius ? 
salicis (m) from trauerweide (Weeping Willow).
