thorax hand profunde scrobiculatus, parvus, ante medium rotun- 

 dato-ampliatus, latitudine paulo brevior, basi apice tertio angustior, 

 angulis anticis acuminatis, supra convexus, antice deflexus, postice 

 sub-gibbosis, medio linea longitudinali nuda ; elytra antice latitudine 

 baseos prothoracis, a basi pone medium inflata, thorace triple 

 longiora, medio magis duplo latiora, supra valde convexa, declivia, 

 crebre punctata, postice rugosula, lateribus apice tenuiter granulatis, 

 costis septem undulatis, obsolete elevatis, aequali spatio distantibus, 

 postice abbreviatis, nee prope ad basim extensis, utrinque praedita; 

 pedes sub-validi, dense fulvo pilosi. Long. 16 mm. ; lat. 9 mm. 



Not unlike in general appearance P. scaber, Fabr. ; the form of the 

 prothorax is nearly similar, but it is scrobiculate instead of being 

 smooth or nearly so, and the elytra, which are also very different in 

 sculpture, are very much more attenuate at the base. 



Male unknown.

PSAMMODES DISSOCIATUS. 



Niger, sub-nitidus, supra terrene squamosus ; caput crebre scrobi- 

 culatum ; prothorax ante medium rotundato ampliatus, pone medium 

 leviter attenuatus, longitudine quarto latior, basi apice tertio angustior, 

 angulis anticis acute productis, supra antice deflexus, postice sub- 

 gibbosus, crebre punctatus, punctis confluentibus, marginibus totis 

 carinatis ; elytra antice latitudine baseos prothoracis, pone humeros 

 rotundato ampliatis, medio thorace duplo latiora, postice angustata, 

 supra deplanata, postice declivia, lateribus sub-verticalibus, crebre 

 punctulata, pube squamosa obsita, costis in singulo sex longitudi- 

 nalibus, interioribus fere obsoletis, sub-carinatis ; pedes sub-graciles, 

 breves, til)iis fulvo tomentosis. Long. 15^ mm. ; lat. 9 mm. 



This species is not unlike a Dichtha, owing to the costae on the 

 elytra, the outer one of which is distinctly carinate and overhangs 

 the outer margin. The shape of the prothorax is similar to that of 

 P. victns, and is perhaps a little more flattened in the anterior part, 

 but the elytra are much more ampliate from near the shoulders, 

 depressed in the anterior part, and more declivous behind ; the 

 costae are not wavy, and are more distinct.
