HIGHEST BEDS OF THE DURHAM COAL MEASURES. 225 
be done opposite to Claxheugh, owing to the smallness of their 
exposure. The position, both of this and the Ancylus bed is 
very high in the Durham Coal Measures; almost higher indeed 
than animal fossils have previously been found. As the amount 
of fault which throws these strata up is not more than thirteen 
fathoms in the neighbouring colliery of Monkwearmouth, their 
stratigraphical position cannot be much over fifty or sixty feet 
from the top of the Coal Measures, or from the base of the 
Lower Red Sandstone. 
XVIII.—Coleopterous Insects added to the Fauna of Northumber- 
land and Durham, in 1863. By Tuomas Joun Boxp. 
1. Trecuus ostusus, Hrichson. 
Rye, Entomologist’s Annual, 1864, 33, 2. 
Not rare in our district; principally affecting woods, and 
living amongst the fallen leaves. I have also found it to 
frequent recently mown grass, by wood sides. It occurs all 
through the summer. 
2. Bempipium [Tacuys] Focxu, Hummel. 
Rye, J. e. 34, 3. 
New to the British Fauna. Six specimens, taken near South 
Shields, are the only known British examples of this scarce and 
curious creature. 
3. IscHNoGLOssA CoRTICALIS, Steph. 
I. rufopicea, Kraatz, Insecten Deutschlands, ii. 59 2. 
Taken by the Rey. R. Kirwood, at Saltwell. 
4. I. corticina, Erich. 
Kraatz, J. c. 59, 3. 
Both these insects appear to be very rare, and only single 
specimens have been taken of each. The last I took at Gosforth. 
5. Inyopates niericotuis, Payk. 
Kraatz, l. c. 184, 1. 
Rare; taken on the sands between Whitley and Hartley in 
May.
