232 Mr. Westwood on the Affinities of Clinidium. 



Latreille upon the tarsal system, which we have been taught to consider 

 as regarded by that distinguished entomologist as a perfectly natural one. 

 The genus was established in the Histoire Katurelle, &c. Vol. XI, p. 

 252, and inserted in the family Cucujipes, and the following extract will 

 assist the student, not only in acquiring a knowledge of some of its pe- 

 culiar characters, but also in noticing the first arguments of Latreille in 

 favour of its situation amongst the Tetramera, " Parandra. La seule espece 

 " connue de ce genre resemble singuliferement, au premier coup d'oeil, 

 " a un Lucane, soit par la forme du corps, soit par I'avancement des 

 " mandibules. La meme analogic se retrouve aussi dans d'autres parties 

 " de la bouche, telles que les machoires qui sont egalement alongees et 

 " lineaires; mais la Parandre lisse n'a que quatre articles aux tarses et ses 

 " antennes sont filiformes et entierement grenues. L'avant dernier article 

 " de ces insectes est un peu bifide, pour recevoir un petit renflement qui 

 " est a la base du dernier. Ce renflement semble former un petit arti- 

 " cle, et c'est ce qui en a impose a De Geer qui lui en a donne cinq ; 

 " les Capricornes ont leur derniere piece des tarses conformee de la meme 

 " maniere etcependant, de I'aveu de tous les entomologistes, ces insectes 

 " n'ont que quatre pieces a ces parties. La forme de ce dernier article 

 " des tarses des Parandres, leurs palpes filiformes, la saillie de leurs 

 " mandibules, leur corps assez epais quoique deprime, sont des caracteres 

 *' qui eloignent ce genre de ceux de Cucuje et d'Uleiote de la meme fa- 

 " mille." 



In the " Genera Custaceorum,'' &c. Vol. TIL p. 26, we find the follow- 

 ing note at the foot of the Cucujipes, " Genus nostrum Parandra familiae 

 " sequenti inscribam," and the genus is then described at p. 28, amongst 

 the Prionii, vdlh the follovdng " Observatio. Instrumentis cibariis 

 " genus Lucanis affine, habitu vero et antennis Trogositis, Cucujis, Prio- 

 " nils, proximum. Forsan per Xylophagos Cucujipes ad Prioniorura 

 " familiam transeundum, deinde a Cerambycinis ad Chrysomelinas ; sub- 

 " sequerentur Erotylense, CoccineUidse, Diaperiales, Pimeliariae ; Rhyn- 

 " chophori in extremo positi Coleopteris fines statuerent." 



In the Considerations Generales, p. 228, the first edition of the Regne 

 Jnimaly Vol. III. p. 339, and the Families JSfaturelles, p. 398, the genus 

 is again inserted in the Cucujipes, but in the new edition of the Regne 

 Animal we find it forming the first of ihc Prionii (the first tribe of
