Genus SP]IEN0KAIA, Clark. 



(Ann. & Mag. Nat. Hist. October, ISG5). 



This generic group, unknown to Dr. Chapuis, and reduced by 

 Von Harold into a synonym of Galevucida, is quite distinct from 

 that genus, and is more allied to Ilaplosonyx; from the former 

 it may be known by the different form and sculpture of the 

 thorax, together with the different structure of the antennae; 

 from the latter by the short and equal second and third joints 

 of the antennae, these organs themselves being usually shorter 

 than in Haplosonyj: ; in addition, in Sphenoraia the transverse 

 depression below the basilar space is either t)bsolete or very 

 indistinct, the elytra are more deeply punctured, and the punc- 

 tures are arranged in irregular longitudinal stria>.
