284 A CENTURY OF UNRECORDED LOCAL COLEOPTERA. 
living in apparent harmony with great numbers of Hylobius 
Abietis, and, like them, were feeding on the soft juicy bark 
of the young trees and branches. JI found them, in almost 
every case, on the underside of the trees or branches, and they 
appeared to prefer those lying amongst grass in damp places. 
The sexes are similar in appearance, excepting that the male 
has the rostrum shorter and stouter, and, with the thorax, more 
roughly punctured than in the female. The male is also generally 
smaller than the other sex, but both vary much in size, some 
specimens being as large again as others. Recently developed 
individuals are pale coloured; one that I dug out of a stump 
of Scotch fir, on the 22d of July, was softer, of a paler ferru- 
ginous, and had the scaly bands and spots much darker coloured 
than the generality of specimens. 
As above mentioned, I found them first in May, but by no 
means common ; they were most abundant in the beginning of 
June ; in July they were scarce ; and by the middle of August, 
became so rare, that I relinquished searching for them. 
Specimens have also been found at Dinsdale, by Mr. W. Pea- 
cock ; at Gibside, by Mr. T. Pigg ; and recently I had a pair 
brought me, which were found on Sunderland Pier.
