SOMATODBS TRANSVAALENSIS, n. Sp. 



Plate v., fig. 15. 



Niger, squamis minutis umbrinis vestitus ; caput subpunctulatum 

 fronte profunde impressa, carinulse rostri conspicuae ; prothorax 

 longitudine nonnihil latior, post medium laterum distincte angulatim 

 productus, ubi profunde incisus, postice obtuse at alte tuberculatus, 

 in partem anticam disci late impressus, impressionibus sub 

 levibus a carina elevata divisis, parte postica lateribusque verrucis 

 agglomeratis obstitis, basi contracta, apice latitudine aequante, 

 scutellum nullum ; elytra elongata, longitudinaliter arcuata, pro- 

 thorace quam duplo longiora et ejusdem latitudine maxima baud 

 latiora, in medio laterum baud ampliata, apice conjunctim rotundata, 

 supra convexa, postice dehiscentia tuberculis liberis validis acutis 

 trifariam seriatis utroque prsedita, margine apicali etiam tuberculis 

 humilioribus obsita, interstitiis plus minusve alveolatis ; pedes 

 tenuissime squamosi. 



This species is easily distinguished from its congeners S. variegatus , 

 Waterh., and S. hidentatus, Pering., by the shape of the prothorax 

 the sides of which are incised past the middle, with the posterior 

 part above the suture bluntly tubercular, as well as by the median 

 ridge of the anterior part of the disk, and also by the more arcuate 

 elytra, the seriate tubercles of which are much more developed than 

 in P. hidentatus and do not end in a blunt tubercle at the apex. 



Length 13 mm, ; width 6 mm.

The two South African species I include in this genus differ some- 

 what from Wollaston's figure and descriptions of the St. Helena 

 species in the antennal joints of the funicle being closely set, and 

 in the elytra being costate. Both have the scape fringed inwardly
