Mr. Marsham*s additional Remarh, \ 4 ; 



The foregoing obfervations of Mr. Markwick funiilh another in- 

 flance of the deftrudtive property of infccfts to the agricuUurc 

 of this country, prove the ncceffity, particularly at this time, of a 

 minute inveftigation into the caufesof the failure of crops, and fully 

 evinces that the pra6lical entomologiO: is a valuable member of ibciety ; 

 as, by difcovering the oecbnomy and perfe£l hilloiy of thefe minute de- 

 ftroyers, and afcertaining, as much as pofTiblc, the injury they do, we 

 may either be enabled to difcover a remedy to the evil, or to diliipate 

 our fears when we perceive, as in the cafe of the wheat infed fo fully 

 defcribed by this gentleman and Mr. Kirby, that Providence has fct 

 bounds to their mifchief, and provided a fuitable check to prevent 

 its increafe. The infed here mentioned has been defcribed by feve- 

 ral authors, fome of whom have given a figure of it ; but they all 

 appear to have been unacquainted with its hiftory except the great 

 Linne, for it is without doubt the CurcuUo Trifolii of that celebrated 

 naturalifl, and defcribed by him in the Appendix Animalium^ Syjl. 

 Nat, vol. iii. p. 224. where he fays, '* Habitat m Trifolii montani 

 fpicis, intra quns declaratur^ It is alfo, I prefume, the CurcuUo fiavipa 

 of Fabricius, Syjiema JLntomologia: ^ p. 133, n. '^2)t ^'^'^ ^^ Paykul's Mo- 

 nograph, n. 135; but they only obferve, " Habitat frcquens primo 

 'vere locis apricis calidiorihus*' GeofFroy calls it le Bccmare noire a pattes 

 fauveSy in his Hijloire Abregk des Infedles, torn. i. p. 272, n. 8. and adds 

 to the defcription *' On le trouvefur lesjieurs" Fabricius in his En- 

 tomologia Syfiematica emendata has removed it from the genus CurcuUo^ 

 and attached it to that of Attelabus, in which he has been followed 

 by Panzer in his Entomohgia Germanica^ p. 298, n. 22, and Fauna 

 Germanlca 20, tab. 13, but I think without reafon, and they add 

 nothing to its hiftory. The latter author fays " Habitat in falice^ 

 populo, primo vere\'* but taking the Habitat merely from the plants 

 on which infe6ls are found, without further examination, muft 

 frequently lead to error, I had examined this mfe<St in its per- 

 VoL. VI. U , fed
