The primary classification of the Longieornia {CerambycAda, 
Thoms.) proposed by Thomson Systema Cerambycidarum^), 
is as follows ; — 
Legion I. ISlETAULACNEMITiE. 
Anterior tibiae obliquely silicate within towards the apex. 
Tribe T. LamitcB. Pro thorax usually not margined at the sides, apparently 
composed of two pieces; eyes lunulate ; palpi filiform; anterior coxae 
globose. 
Legion II. Anaui-acnemitje. 
Anterior tibiae not sulcate within. 
Tribe 2. LcpturitcB. Prothorax as in Lamitm ; eyes subrotundate or lunu- 
late ; palpi usually compressed ; anterior coxae conical. 
Tribe 3. Cerarnhycitce, Prothorax, &c., as in preceding; anterior coxae 
globose. 
Tribe 4. SpondylitcB. Prothorax, &c., as in preceding ; anterior coxae sub- 
transyerse. 
Tribe 5. Prionitoi, Prothorax margined at the sides, apparently composed 
of four pieces ; eyes lunulate ; anterior coxae very transverse. 
As the author adopts an immense series of groups inferior to 
the tribes, amounting in many cases to four or even five grades 
subordinate one to the other, and the number of new genera 
established is enormous, it would be impossible, without trans- 
ferring the greater part of the contents of his work to our pages,“ 
to give any idea of the characters by which these groups are dis- 
tinguished. However, M. Thomson's work is quite indispensable 
to every one who studies this family or part of it, and we could not 
supply anything like an abstract really useful to the student *. 
The new genera and species will be referred to hereafter. 
Leon Fairmaire (Genera des Coleopteres d’Europe), in his 
classification of the Cerambycidee, likewise creates a great num- 
ber of subordinate groups. His 
Divisiou I. includes only the Group Spondylites. 
Division II. {—Prmutce, Thoms.) includes PrioniteSf Ergatites, Ti'ogoso- 
mites, and JEgosomites. 
Division III. ( = Ceramhyciice, Thoms.) includes AsSmites, Anisarthrites, 
Criocepimlites, Saphanites, Clytites, Ilesp&rophaydtes, Callidiites, Rosaliites, 
Cci’amby cites, Gvaciliites, LeptidHtes, Stenopterites, and Deilites, 
Division IV. {=Lamitce, Thoms.) includes JEdilites, Exocentrites, Acan- 
thodh'ites, Pogonoc7i4rites, Monohmmnites, Lamiites, Dorcadionites, Mesosites, 
* The Recorder’s manuscript contained a detailed analytical table of 
M. Thomson’s classification, and we regret very much that want of space 
absolutely prevents us from publishing it this year. In this course we may 
be to a certain extent justified by the circumstance that the author will 
probably make many adclitions to the genera, &c., before he has completed 
his tables of classification. — Editor.
