in tlie middle, its extxeme front part piinctured and with fulvoiis setae, 

 its posterior part finely chanelled , tlie portion between the legs 

 shining and impunctate, tlie sides densely punctured and furnislied 

 with fulvous setae: the segments of the abdomen punctured and seti- 

 gerous at the sides, smooth in the middle. Teeth of the front tibiae 

 Short and stout; the spur of the bind tibiae elongate, longer than the 

 basal Joint of the tarsus. 



The only specimen I have secn of this remarkable species was 

 found at Sarawak by Mr. Wallace. 



OnthopJiagus dux (n. sp.) : Clypeo thoraceq^ie cupreis , üLo an- 

 terius nigrescente ; elytris opacis nigris, pygidio corporeque suhtus leviter 

 metallescentihus , pedibus superne nigris; clypeo margine anteriore imi- 

 dentato, vertice tuherculato-cornuto ;\ prothorace anterius media lohato-pro- 

 ducto, densius granulato, gramdis minus elevatis; elytris crenato-striatis, 

 interstitiis siibtiliter punctatis ; corpore supra nudo, suhtus fuho-setige^-o. 

 — Long. 15, lat. 9 mill. 



Antennae red, with the third Joint small, the seventh large, its 

 under part produced so as to form a half cup, the 8th Joint on the 

 undersurface with its margin cut away, so as to be concealed there 

 between the 7th and 9th joints. Labial palpi with a minute third 

 Joint. Clypeus with a short tooth in the middle in front, the extreme 

 Vertex furnished with a laterally compressed tubercle or short hörn 

 which projects forwards rather than upwards; its surface is densely 

 and rugosely though not coarsely punctured, the front part is black, 

 the hinder part coppery. Thorax with the front angles rather produ- 

 ced, the bind ones extremely obtuse, the sides abruptly narrowed be- 

 hind the middle , the whole of its upper surface is densely covered 

 with flat scale-like granulations , the front part is produced in the 

 middle as an obtusely pointed lobe , directed forwards. The elytra 

 are distinctly crenate-striate , the interstices aro quite flat and finely 

 punctured , and are also finely coriaceous , which gives them a dull 

 silky appearance. Pygidium densely , confluently punctured. Meta- 

 sternum very conically protuberant iu the middle in front, finely chan- 

 nelled along the middle, the front part with long fulvous setae, the 

 sides densely punctured and setigerous ; the anterior tibiae large and 

 short, with long and stout, but not very pointed teeth. The under
