Ohs. — Mr. Saunders (Synops., p. 287) has described P. lifusciaiits 

 as narrower than clavatus, but this is not correct. Kirsclibaum has 

 already said (Kh. Wiesb., p. 137) that his cinnamopterus differs from 

 clavatus by the hroader pronotum. Is it possible that the British 

 Hemipterists have confounded two species ? P. hifasciatits in kSweden 

 and Finland is found only on Pimis (Prof. Kirsclibaum has also taken 

 this species on^rs),but Mr. Saunders and Dr. Eieber indicate that it 

 lives also on oaks. This, if referring to one species, would be a very 

 peculiar feature, for scarcely any other of Ihe Capsida; lives on ConiJ'crcd 

 and also on foliage-trees.
