Genus Amphibitherion new genus. 



Head slightly transverse, eyes large, infralateral carince fine and 

 entire; antenna; long and slender, second and third joints equal, not 

 much longer than the fourth which is elongate, tenth joint not 

 transverse. Mouth parts as in the genus Athcta. 



Thorax and elytra moderately transverse. 



Abdomen subparallel. fifth segment not narrower. Dorsal seg- 

 ments uniformly, almost coarsely and somewhat closely punctured, 

 fourth and fifth not more shining, punctuation much more distinct 

 than that of the anterior parts. 



Intermediate coxa^ distinctly though narrowly separated; sternal 

 projections contiguous at their middle; metasternal projection with 

 its upper surface evenly convex, l)ut inclined slightly anteriorly so 

 as to pass beneath the point of the mesosternal projection, anterior 

 marginal line of the metasternum very feebl}' rounded between the 

 cox;e. 



Four basal joints of the posterior tarsi slightly elongate, of sub- 

 equal length. 



The distinctly separated intermediate coxa?, the long, slender an- 

 tennae with the second and third joints of equal length and the 

 uniformly punctured abdomen distinguish this genus from Mctaxia, 

 Traumoccia and Athcta, to all of which genera it is closely related. 



Amphibitherion demissum new species. 



Form rather slender, subdepressed, parallel. Color black, antennae and 

 thora.\ blackish piceous, the former not paler basally, elytra and legs paler. 

 Integuments extremely finely micro-reticulate; punctures on the head sparse 

 and indistinct, on thorax and elytra close but indistinct, on abdomen rather 

 coarse and close ; pubescence on thorax and elytra fine and dense, fulvo- 

 cinereous. Head slightly transverse, scarcely narrower than the thorax, eyes 

 large, tempora parallel, scarcely two thirds the length of the eye, vertex with 

 a shallow impression, antenna; surpassing the base of the thorax, scarcely at 

 ill incrassate. second and third joints about one half longer than wide, fourth 

 joint elongate, a little shorter than the third, five to seven very slightly elon- 

 gate, eight to ten as long as wide, terminal joint long, parallel, as long as the 

 two preceding. Thorax nearly a third wider than long, about four fifths the 

 width of the elytra, widest slightly before the middle, sides feebly arcuate, disk
