The Genus now under consideration has been named Pogonus 

 by one author, and Raptor by another; and not knowing 

 which is entitled to priority, I have followed the Baron Dejean 

 in adopting the former, not doubting but he had just reasons 

 for so doing. I am also inclined to believe, that either no 

 characters liave hitherto been published of this genus, or that 

 they have not yet reached this country ; I have therefore been 

 under the necessity of drawing the best I could from our three 

 species, as well as a specific description of the beautiful indivi- 

 dual selected for illustration, it never having been before de- 

 scribed, although it was named many years since, by A. H. 

 Haworth, Esq., after our old and esteemed friend the Rev. 

 J. Burrell, F.L.S., by whom it was jfirst detected in 1806, and 

 to whom I am indebted for specimens, and the following par- 

 ticulars : " The Genus Raptor^ confined as it is to three British 

 species [Burrellii Haw.; cJialceus Marsh.; and (smginosus 

 Steph. MSS.), is perfectly maritime; the species being all 

 found in the same situation, and may be deemed subaquatic ; 

 for in tlie winter, and a considerable part of the summer, the 

 habitat of these pretty animals is entirely covered with water, 

 which stagnates many inches deep in the low places of the 

 marshes after the tide has flowed and ebbed. When these spots, 

 which are first formed by a casual removal of the oozy soil for 

 agricultural purposes, are dried, through evaporation caused by 

 the summer sun, the soil cracks in various directions, and out 

 of these cracks, when any one walks across the place, the 

 RajJtores dart up with swiftness and in great numbers. They 

 are principally found in the months of June, July, August, 

 and September; and if the weather be warm and dry, they may 

 be captured, though in less quantity, in May and October. 

 They associate with many species of Bembidinm^ and not un- 

 frequently the Cillenum laterale is seen in their company. 

 The most manifest habitat of our species is at Salthouse in 

 Norfolk, upon the salt marshes separated from the German 

 Ocean by a high mound of pebbles and other small stones 

 rounded by attrition, and through which mound the tide 

 penetrates at its highest flow." 



The male is somewhat smaller than the female, but both 

 sexes vary in magnitude. Its food is undoubtedly similar to 

 that of other Carahidtv^ and the soil is productive of very few 

 plants: among these, however, the Statice Limonium (Lavender 

 Thrift) is handsome and common ; it is therefore made the 

 accompaniment of the plate.
