GEN. STENOCAEA, Sol. 

 STENOCARA NAMAQUA. 



Nigra, capite prothoraceque opacis, elytris nitidis, antennis, palpis 

 pedibusque rufescentibus ; caput vix punctatum ; prothorax longi- 

 tudine duplo latior, apice basi fere dimidio angustior, lateribus rectis 

 margine apicali angulata, supra parum convexus, fere levis, medio 

 vage arcuatim impressus ; elytra valde rotundata, medio thoracis 

 basi duplo latiora, apice abrupte declivia et acuminata, profunde 

 scrobiculato-rugosa, sutura sub-levi, elevata costisque sub-tubercu- 

 losis duabus utrinque prsedita, margine lateral! e tuberculis rugatis, 

 bi-seriatis formata, epipleura lata, profunde scrobiculata ; antennae 

 graciles ; pedes elongati, gracilimi. Long. 12 mm. ; lat 7 mm. 



This species as well as the following one are sufficiently dis- 

 tinguishable from the other South African species owing to the 

 rotund shape of the elytra from a short distance from the base, and 

 the abrupt posterior declivity ; the legs are also very slender, but 

 not, however, quite as filiform as in P. gracilipes, Sol. The two 

 dorsal, tuberculated, nearly serrate, dorsal ridges in the elytra are 

 very well denned, and the intervals are filled with a double series of 

 irregular, scrobiculate, broad punctures the median wall of which is 

 somewhat granulose.

STENOCARA PLACITA. 



Nigra, nitida, indumento albido nonnunquam vestita, antennis 

 pedibusque sub-rufo piceis ; caput crebre punctulatum, antice inter 

 antennas profunde impressum ; prothorax longitudine magis quam 

 duplo latior, lateribus rnodice rotundatis, margine apicis angulata, 

 basi sub-sinuatus, supra in medio convexus, ad latera deplanatus, 

 profunde punctatus, intra basim transverse impressus ; elytra 

 rotundata, convexa, apice valde declivia, et acuminata, in medio 

 thoracis latitudine maxima fere duplo latiora, tuberculis conicis 

 seriatis confertim instructis obsita, epipleura lata, verrucosula ; 

 pedes graciles, elongati. Long. 11 mm. ; lat. 7 mm. 



In shape this species approximates S. ncunaqita, but the head and 

 prothorax are punctured instead of being smooth, the sides of the 

 prothorax are a little ampliated in the middle, and the outer 

 margins depressed, whereas they are straight in S. namaqua, and 

 the elytra instead of having two tuberculose ridges on each side are
