[Note. — In figures 4, 11, 12, 16, certain of the appendages are 

 represented by dotted lines. The specimens are not defective, 

 but the appendages are bent beneath them and invisible from above ; 

 and the insects being very hard to relax, and in three of the cases 

 unique, did not admit of the manipulation necessary to spread the 

 appendages out. 



It is almost impossible to represent adequately the remarkable 

 depth of the cavities on the thorax in figs. 12 and 13.- — H. S.]
