South African Coleopterous Fauna. 255 



interstitiis serie e punctis minoribus crebris formata ; subtus sat 

 fortiter dense punctatus, pectore abdominisque lateribus punctis 

 distinctioribus. Long. 11 mm. ; lat. 3 nun. 



Male unknown. 



The distinctive characters of this species are : the orbicular pro- 

 thorax, the narrower shape of the elytra, which are hardly broader 

 at the widest part than the prothorax, and the sculpture of the 

 elytra which are striate with the striae filled with confluent, equal 

 punctures, whereas in all the other species the punctures form the 

 strite. 



Hab. Damaraland (Goagas). C. Walmer. 



DEEOSTEOPHUS HUMILIS. 



Piceus vel rufo-brunneus ; caput punctulatum, antennae pone 

 basim elytrorum vix attingentes ; prothorax apice basi haud angus- 

 tior, vix latior quam longior, angulis anticis posticisque rectis, his 

 sub-prominulis, lateribus ab apice prope basim leviter rotundatis, 

 vix ampliatis, supra perparum convexus, crebre punctatus ; elytra 

 elongata, basi prothorace nonnihil, post medium tertio latiora, supra 

 convexa, in dorso punctato-striata, lateribus striato-punctatis, inter- 

 stitiis serie e punctis minoribus formata, in disco minus, lateraliter 

 magis distincta ; corpus subtus pedesque ut in praecedenti. ? Long. 

 10-11 mm. : lat. 3f mm. 



Resembles the female of D. mandibularis ; but the prothorax is 

 longer in proportion to the width, and therefore less rounded 

 laterally : the sculpture of the intervals differs, the intervals in 

 7). mandibularis being impunctate.
