This species, and also the following ones, are distinguishable by 

 the very convex, nearly globose prothorax. 



PSAMMODES ADVENTITUS. 



Niger, sub-opacus ; pilis sub-brevibus sat dense obsitus, antennis 

 pedibusque ferrugineis ; caput epistomaque scrobiculata, oculi pro- 

 minuli ; prothorax latitudine baud longior, sub-globosus, basi 

 apiceque latitudine adyequans, crebre aciculatus, pilosulus ; elytris 

 basi prothoracis latitudine maxima baud latiora, ad humeros obliqua, 

 medio paullum ampliata, ubi prothorace tertio latiora, versus apicem 

 modice acuininata, supra convexa, costis tribus sub-rotundatis apicem 

 hand attingentibus in singulo prscdita, obsolete punctulata, sat dense 

 pilosula ; pedes rugosuli, longe pilosi, tarsis elongatis. Long. 

 20 mm. ; lat. 8 mm. 



Allied to P.profugus, but differs in the sculpture of the head which 

 is scrobiculate longitudinally ; the prothorax is less globose ; the 

 elytra are more ampliated in the middle, less convex and less sharply 

 acuminate behind, the disk is hardly punctulate instead of being 

 granulose, the suture is not raised, and the tarsi are much longer.

Nigro piceus, labro, antennis, pedibus tarsisque ferrugineis, caput 

 prothoraceque crebre sed baud profunde punctulati, hie latitudine 

 parum longior, lateribus modice rotundato-ampliatis, basi apice 

 nonnihil angustior, angulis anticis acuminato productis, basalibus 

 obtusis, supra convexus, intra basim distincte transversim impressus ; 

 elytra elongata, antice fere latitudine baseos thoracis, medio tertio 

 latiora, apice acuminata, supra convexa, crebre minuteque rugoso- 

 punctata pubeque brevi sub-flavescente, posterius densiore tecta ;

 pilosi.
