The specimen figured was taken by the gentleman in whose 

 cabinet it is now preserved, in his house at Drumseugh, Edin- 

 burirh, the end of August 1820: its natural situation in the 

 genus is between S. Menthastri (which it most resembles in the 

 colour of its legs and the disposition of its markings) and 

 (S. Iuh7'icipeda, the female of which it comes very close to in 

 colour. Mr. Haworth has a fine species also resembling S, 

 Walkerii in markings ; but it is smaller, and I think formed 

 more like S. jpapyritia. 



In the structure of the mouth and the antennae this group 

 approaches exceedingly near to Eyprepia (plate 21). Mr. 

 Stephens has called it Spilosoma, from their spotted bodies. 

 The following species can now be enumerated as British. 



1. Spilosoma lubricipeda Linn., Don. v. 16.pl. 568. 



2. Walkerii Nob. 



3. Menthastri Fab. Erminea Mars. Linn. 



Trans, v. 1. p. 70. 



4. Urticae Hub. 2. L. b, b.c: from Yorkshire, in 



Mr. Haworth's cabinet. 



5. papyritia Mars. Li7in. Trans, v. 1 . p. 70. 



6. radiata Haw. MSS. 



The plant figured is Pirnpinella saxifraga (Common Burnet 

 Saxifrage).
