ventral segments running for the most part irregularly down the 

 middle line similar to the non-depressed parts of the upper surface. 

 The antennae are of obscure pitchy appearance ; the V)asal portion 

 of each joint, however, to a decreasing extent from the basal joint, 

 is reddish. The widest part of the prothorax is about | the width 

 of the widest part of the elytra.

ELATERID^. 

 Tetralobus thoracicus, sp.nov. 

 Parallelus ; testaceus ; capite prothoraceque piceo-nigris, 

 crebre crasse valde rugulose punctulatis ; hoc quam latiori 

 longiori nee canaliculato nee foveato, latitudine majori ad 

 marginem anticum posita, angulis anticis productis lobatis ; 

 prothoracis lateribus ab angulis anticis longe post medium 

 leviter convergentibus, hinc divergentibus et utrinque in 

 spinam acntam uncinatam retrorsum directam productis, pone 

 spinam ad basin fortiter arcuatim convergentibus, basi fortiter 

 emarginata ; elytris breviter sat dense pubescentibus, leviter 

 sei'iatim punctulatis, puncturis subquadratis, interstitiis 

 angustis leviter carinatis, et puncturis et costis apicem versus 

 subobsoletis, sutura in spinam producta ; antennis laste 

 testaceis vix prothoracis spinam attingentibus, longe flabellatis, 

 flabellis quam inter oculos capitis latitudinem vix brevioi'ibus.

 The very peculiar shape of the prothorax at once distinguishes 

 this species from all its congeners yet described.
