660 Longicornia Malayana. 



pubescence, subseriate-punctate, but glabrous posteriorly, 

 the apex of each bimucronate ; body beneath grayish- 

 blue, sparsely pubescent ; legs and antennse bi'ight 

 gamboge-yellow, the clavate portion of the femora glossy 

 violet; antennee half as long again as the body. 



Length 9 lines. 



M. Lacordaire's second cohort " Ceramhycides vrais 

 souterrains," includes two subfamilies — Apatophy since, and 

 Vesperince. Only the first of these possesses a Malayan 

 form, Trypogceus, described by M. Lacordaire from a 

 female example in the collection of Count Mniszech, which 

 he names T. albicornis. It has a short thick Toxotus-like 

 habit, and is covered with a silky golden down; the 

 antennae black, with the first and second joints fulvous, 

 and the ninth, tenth, and eleventh white; the abdomen 

 with numerous bright luteous spots. 



PRIONID^. 



M. James Thomson, in his 8ystema Ceravihycidarum, 

 divides the Longicoms, which for him, as for M. Lacor- 

 daire and other authors, are simply a " family," * into five 

 tribes, the last being the Prionidce ; and outside the 

 longicorns altogether, he establishes six additional, and 

 what he denominates " limitrophal," families. M. Lacor- 

 daire adopts this arrangement to a certain extent, but 

 excluding Tricteyiotomidm, which he agrees in considering 

 a distinct family, he places all the others, except Thau- 

 masidce, Thoms., in his "Legion" of " Prionides aher- 

 rants/' together with " Oantharocnemides " and " Sceleo- 

 cantJiides," which M. Thomson combined to form his 

 second section of Prionidce. I confess I think M. Thom- 

 son's arrangement the more natural, and that it is more 

 consistent with the principles of limitation applied to the 



* On what principle are the Phalacridce separated from the Nitidulddce, 

 or the Ptinidce from the Bostrichidce, and so on, as families, if the La- 

 tniidce, or the Prionidce, have no higher rank than a "tribe"? It is 

 true that M. Lacordaire tlainks that the three primary groups of longicoms 

 are sufficiently important to he raised to the rank of suhfamihes (here used 

 for the first time in the *' Genera "), the subfamily being, with him, above 

 the legion or tribe ; and the "tribe" is afterwards confined to the aberrant 

 forms of Prionido}.
