236 Dr, T, A. Chapman’s 
The indications of the articulated base of the clasps and the open 
(2. e. unchitinised) side are sketchy and only of use as showing the 
angle at which the clasp is viewed ; a slightly different angle alters 
the outline of these so much, that only with elaborate drawings 
could their real differences be shown. 
The same remarks apply to the tegumina, some differences in the 
figures are due to different angles of view, and in certain cases to 
the preparation being in some degree under pressure ; these rarely 
prevent a due comparison of lengths, curves, sharpnesses, &c., of the 
processes. 
The name of a locality after the description of a figure indicates 
that the specimen figured was obtained at that place, after the name 
of a species or variety, that all the examples thereof figured were 
obtained there. 
Where preparations have been figured from a single example, the 
descriptions of them are separated by commas only, where from 
different examples of the same species or variety, by semicolons.
