EXPLANATION OF PLATE XVIII. figs. 3-5. 



Fig. 3. Diastylis himarginatus.

Fig. 5. Fragments of legs of same : i, part of first leg ; 2, part of second 

 leg ; and so on to 5, which is the last. 



Note. 



Since the above was placed in the hands of the printer, I have 

 seen, in the 'Annals' for Nov., a reference made by the Rev. A. 

 M. Norman to the species above referred to, in which he says that 

 Diastylis himarginatus is identical with D. spinot^a, a species de- 

 scribed by him in the British -Association Report for 1868. This 

 he considers must be the case from the similarity of the description 

 given by him and that of my species as given by Mr. Bate in the May 

 number of the ' Annals ;' but then it will be seen from the fore- 

 going that Mr. Bate's remarks do not describe the species I sent 

 him.
