granulosum, palporum maxillarum articulo ultimo securiformi ; 

 prothorax pavum rotundato-ampliatus, longitudine tertio latior, 

 basi emarginatus angulis rotundatis, apice sub-sinuatus angulis 

 acutis, valde prominulis, totus distincte marginatus, supra convexus, 

 crebre distincteque granulosus, granulis elongatis ; elytra antice lati- 

 tudine baseos prothoracis, aequalia ad hurneros ampliata, sub-ovalia, 

 versus apiceni acuminata, supra convexa, postice longe dehiscentia 

 apiceque deplanata, crebre distincteque granulosa, granulis apice 

 minirnis et sparsis, margine laterali acuta, reflexa ; pedes breves, 

 rugosi, posticis intermediisque sub-gracilibus ; antennae graciles. 

 Long. 15-24 rnm. ; lat. 8-13 mm. 



3 . Abdom. segment, tribus vel quatuor basalibus in medio late 

 errugineo tomentosis. 



Easily recognised by the opaque colour of tbe upper side and the 

 very distinct granulation of the prothorax and elytra ; in the small 

 examples from Namaqualand the posterior part of the elytra is more 

 abruptly dehiscent than in larger specimens from Damaraland.

PSAMMODES DUBIOSUS. 



Niger, nitidus, antennis tarsisque ferrugineis ; caput antice rugose 

 punctatum, postice granulatum ; prothorax fere ut in specie 

 praecedente, sed magis parallelus, supra granulis rotundatis nonnihil 

 validioribus breviterque setiferis crebre obsitus ; elytra ovalia, 

 versus apicem acuminata, medio prothorace tertio latiora, 

 convexa, longe dehiscentia, apice haud deplanata, margins laterali 

 acuta, crebre distincteque granulosa, granulis brevissime setiferis ; 

 pedes breves, rugosi. Long. 19 mm. ; lat. 10 mm. 



$ . Pectore abdominisque segmentibus omnibus in medio fulvo 

 tomentosis. 



Distinguished from the preceding species mainly by the more 

 rounded granules which are slightly wider apart on the prothorax, 

 and more closely set on the elytra ; they are also very briefly 

 setigerous, and the marginal part of the apex is not depressed. 



Ilab. Damaraland (Angra Pequeiia). 



PSAMMODES VEXATOR. 



Brunneo niger, nitidus ; antennis ferrugineis, crassiusculis ; caput 

 antice late rudeque punctatum, postice strigillatum ; prothorax 

 latitudine fere quarto longior, in medio paullum rotundato ampliatus,
