+44 This Crabro, which is unique in the cabinet of Mr. 
Westwood, is the only one I am acquainted with that has 
the anterior portion of the metathorax transversely striated, 
from which circumstance I have named it. It would come 
into St. Fargeau’s genus Crossocerus, and near his Cros. 
pusillus, but it does not appear to be described by him. [ 
cannot learn where it was taken.
