HoMOLOTROPOS. n. gen. 



Antennae of nine joints : 1st. long, clavate ; 2ncl. globular ; 

 3rd. slight and cylindrical ; 4th. short ; the remaining five joints 

 forming a club with the laminae long. Labrum transverse, deeply 

 emarginate. Mentum rough, broad at the apex and slightly 

 emarginate. Palpi with the terminal joints a little longer than 

 the others. Suture of clypeus indistinct. Thorax lobed behind. 

 Elytra not covering the pygidiura. Fore tibiae strongly tridentate. 

 Body oblong flat. 



The position of this genus is evidently near the genus 

 Xylonychus MacLeay. That genus seems to me to be more 

 naturally placed among the Meter onyci doe, of Lacordaire, than as 

 he has placed it, among the true MelolonthidcB.
