Long. 54 lin. J". 



One example, in Mr. Belt's collection. It is closely 

 allied to A. princeps, but the prominences on the forehead 

 show a relationship to the genus Phcehe. 



Amphionyclia capito, Bates, Ann. Mag. Nat. Hist. 

 June, 1866. — A unique example, possibly distinct, differ- 

 ing from the type (from Panama) in the head being

EuLACHNEsrA, nov. gen. 



Inter AmpMony chinas et ^renicinas medium tenet. 

 Caput exsertum ; elytra lateraliter carinata ; ungues fis- 

 siles ; antennse elongatae, robustse, omnino infra dense 

 cilia t^e, articulo 3io quam 4to dimidio longiori. Corpus 

 ut in Gen. AmpMonycha elongatum, postice attenuatum ; 

 tibiae intei-mediae extus integrjfi. 



The head in this genus is not retractile as in the Am- 

 phionychince, to which it belongs by the carinated elytra ; 

 and it differs also from them in the thick, filiform, and 

 densely ciliated antennse. The eyes are more distant 

 from the prothorax even than in JErenica. The type will 

 be Amphionyclia Sapphira (Bates, Ann. Mag. N. H. June, 

 1866), with which the following beautiful species is to be 

 associated, having the same peculiar style of coloration.
