Longicornia Malayana. 497 



CERAMBYCID^. 



The remainder of this work, including the Ceramhycidce 

 and PrionidcB, will be arranged almost entirely after the 

 method of Prof. Lacordaire, recently published in the 

 eighth volume of his " Genera/' so far as it goes in the 

 treatment of the former family. The illustrious author, 

 returning to the old plan, commences his arrangement 

 with the Prioiiidce, and ends with the Lainiuke : the 

 Lepturidce, after Dr. Leconte, who in this matter has 

 been followed by M. James Thomson* and myself, beino- 

 considered a simple group of Cerambycidce. Having be^ 

 gun with the Lamiidce, it will here be necessary to take 

 the Ceramhycidce before the Prionidce. 



As all interested in the subject will be in possession of 

 M. Lacordaire's volume, it will be imnecessary to do 

 more here than to show how it is proposed to deal with 

 his arrangement in applying it to the remainder of the 

 nresent work. As in the preceding volumes of the 

 ''Grenera" M. Lacordaire makes several subordinate 

 divisions between the "sub-family" and the genus, such 

 as tribes, legions, cohorts, &c.; on these I do not propose 

 to enter, as they are mostly merely names designating 

 the different stages of a dichotomous classification. His 

 " groupes," however, are truly natural so far as our know- 

 ledge of the species extends, and the grave difficulties of 

 the subject admit, and these "groupes" become in our 

 arrangement, sub-families. 



Four remarkable genera, having scarcely anything in 

 common, except two of them, are first separated as 

 "Legion 1.'' None of these belong to the Malayan 

 fauna. The true Ceramhycidce, — ''Legion 2" — includes 

 two cohorts. The first " Ceramhycldes vrais sylvains" are 

 solely distinguished by the intercoxal process being in 

 the form of an " elongate triangle, moi^e or less acute, 

 very rarely short." This cohort exhausts the eighth 

 volume, and it will take a large part of the ninth to 

 complete it. The work being in this respect unfinished, 



^ * "Essai," &c., p. 331. The " Lepturitas" formed one of the then 

 " Legions" of Cerambycidce. In the " Systema" they once more consti- 

 tute a " tribe " equivalent to the Cerambycidae.
