ANTOLIGOSTETHUS (gen. nov.). 



"Caput antice perpendiculare ; labrum fortiter transversum ; 



antennae sat fortiter serrate, articulis 3° quam 2 US multo 



longiori, 11° subappendiculato ; prothorax a basi ad 



apicem angustatus, ad later a marginatus, margine antice 



fortiter deflexo (superne viso haud perspicuo) ; pros- 



ternum antice rotundatim truncatum, suturis sinuatis 



antice clausis haud duplicatis ; tarsi subtus haud 



laminati ; coxae inter mediae contiguae. 



The characters cited above will serve in combination to 



distinguish this genus from all those described in the "Genus 



Insectorum." It is probably nearest to the South African 



genus Oligostethus, Schw., but differs from it by, inter alia, 



the antennae strongly serrate from the 3rd joint inclusive, 



the strongly transverse labrum, and the prosternal sutures 



not open in front. 



A. lucidus, sp. nov. Brunneo-testaoeus ; sat nitidus (prae- 

 sertim pronotum) ; supra pilis brevibus erectis sat dense 

 vestitus ; antennis ultra prothoracis basin elongatis ; 

 capite crebre fortiter punctulato; prothorace quam trans 

 basin latiori parum breviori, supra in disco sparsius sub- 

 tilius (quam caput multo minus crebre multo minus 

 fortiter) latera summa versus magis fortiter punctulato, 

 antice sat fortiter angustato, margine antico rotundatim 

 sat fortiter producto, lateribus fere rectis nonnihil 

 sinuatis, angulis posticis haud divaricatis intra mar- 

 ginem haud carinatis ; scutello ovali ; elytris quam 

 prothorax circiter triplo longioribus, sat fortiter striatis, 

 striis latera versus fortiter punctulatis, interstitiis parum 

 convexis sat crebre minus subtiliter punctulatis, apice vix 

 acuminato fere rotunda to; prosterno crebre fortiter, 

 episternis sparsim subtilius, punctulatis ; processu pro- 

 sternali supra concavo, postice abrupte declivi; coxis 

 intermediis contiguis ; coxis posticis intus gradatim sat 

 fortiter dilatatis ; abdomine sat crebre sat fortiter 

 punctulato ; tarsis posticis quam tibiae paulo brevioribus, 

 articulis 1-4 gradatim brevioribus; unguiculis modice 

 magnis. Long., 5 J 1. ; lat., 1J 1.
