Medeterus has been separated from DoUchopus, and may 

 be distinguished from it by its long thorax, naked seta of the 

 antenna?, by the longer and. more slender appendages to the 

 abdomen of the males, by the transverse nervure of the wings, 

 which is nearer the margin, by the great length of the legs, 

 and the simple posterior tarsi. 



From the want of male specimens of the other species, I am 

 incapable of ascertaining whether the remarkable structure of 

 the anterior tarsi of M. regius be a specific or generic charac- 

 ter : the hairs on the 2nd joint are glandular at the apex, and 

 the 3rd and 4th joints are terminated by a fleshy substance, 

 which is well adapted to its habits of life, and lead us there- 

 fore rather to consider it as an organization pecidiar to itself. 



1. M. notatus. — The first specimens that I noticed of this 

 handsome species, of which there is no figure recorded, were 

 in the cabinet of Mr. Hatchett. Since that period Mr. Ingpen 

 has found a specimen in Kentish-town fields, and another upon 

 the plant represented in the plate, near Bromley, Kent, on the 

 1st of June. 



2. M. regius ^ab., Meig. — virens Panz. 54. 1 6. — I first ob- 

 served this pretty insect resting upon the trunks of trees in 

 the romantic neighbourhood of Lynmouth, North Devon, the 

 middle of September: and the beginning of the same month 

 last year I met with it in abundance near Black-gang Chine 

 in the Isle of Wieht. The face of the cliff' in this neighbour- 

 hood is perpendicular and very wet, the water frequently de- 

 scending in showers from the top : in these situations both 

 sexes of this species delighted, flying when disturbed through 

 the falling spray, and alighting upon the wet surface, from 

 which they stood perfectly clear by placing their long legs not 

 obliquely, but at right angles from the body. 



3. M. viridis Meig. P vol. 4. p. 60. n. 2. — This is a smaller 

 species ; for a specimen of which I am indebted to Mr. Francis 

 Walker, who took it in the vicinity of Southgate. 



The plant is Chrysanthemum Leiicanthemum (Ox-Eye).
