its base like flie pvopygidium and the apex is smooth ; the 

 presternum, anterior lobe very lar2;e, keel narrow between 

 the coxa?, with a loop-sliaped stria, which joins behind ; the 

 mesosternum is widely emarginate, stria complete and is clo?e 

 to the anterior edge ; the metasternum is longitudinally 

 canaliculate in the middle ; the anterior tibiie are 4-dentate 

 and somewhat dilated. 



The size and form of this remarkable species is similar to 

 Pachycrcerus vindis, Mars. Platysoma canalicolle, Mars., 

 lias a stria wliich entirely surrounds the thoracic margin, but 

 it is not so deep and conspicuous as in P. exlrarium.

Pachycrcerus inorulus, sp. n. 



Oblongus, parum ellipticus, subcjlindricus, picoo-niger, nitidus : 

 anteunis pedibusque rufo-bruuneis ; capite punctulato, stria 

 antice integra ; elytris, striis subhumerali extenin, 1-4 suturaliquo 

 integris, 5 basi abbreviata vel evaneseeuti ; prosterno bistriato ; 

 mesosterno antice baud striato. 



L. 3|^ mill. 



Oblong, somewhat elliptical and cylindrical, nearly black, 

 ^vith the antenna? and legs reddish brown ; the head impressed 

 anteriorly, stria complete and anteriorly straight, surface 

 evenly punctulate ; the thorax wider than broad, surface 

 clearly punctured, punctures varying in size, with a very tine 

 punctuation between the larger points, lateral margins are 

 narrowly free of punctures, the lateral marginal stria continues 

 as a very fine stria behind the eye, but it is interrupted 

 behind the middle of the neck ; the elytra — stria?, external 

 subhumeral fine and complete and at the apex turns inwards 

 and terminates at a point behind the second stria, internal 

 fine, basal, and oblique, 1-4 complete, 5 abbreviated at the 

 base or just visible in certain lights, sutural almost complete, 

 arrested at a point level with the scutellum ; the propygidium 

 and jiygidium clearly punctured, punctures are somewhat 

 irregular and leave the pygidium smooth at its apex ; the 

 prosternnm is narrow, bistriate, strice not meeting anteriorly, 

 are nearly parallel at the sides, and widen out slightly between 

 the coxa?; the metasternum is very feebly bisinuous on either 

 side of the acumination, which is small and obtuse ; the 

 meso- and metasterna have each a distinct lateral stria and 

 the first segment of the abdomen has two fine lateral strige on 

 either side ; the anterior tibife have three large teeth in the 

 middle and smaller ones outside of them. 



The elliptical subcylindrical form of this species is unlike
