probably due to the same being taken from different points, that of the cephalie 

 femur on account of his measurement including the coxa, but the pronotal 

 difference is incomprehensible to us. The only explanation which seems at all 

 likely is that the length was taken along the lateral angles of the disk instead of 

 along the median line, as we are accustomed to take the latter measurement ta 

 get the maximum.
