This species is peculiar among the others of this paper by being 

 the only one in which the punctures are not anangcd in stri», 

 but are scattered without arrangement over the whole surface 

 of the elytra. 



I received a single specimen from the collection of the Marquis 

 La Ferte, taken at the Cape. 



10. P. nigro'dtnea, n. sp. 



P. ovalis, punctata, nigro-eenea, nitida ; capite inter oculos transverse 

 et subcirculariter depresso, brevi ; thorace lato, lateribus paralleli:*, 

 antice rotundatis ; angtili.s anticis baud acuminatis, lateribus te- 

 nuiter niarginatis, subtiliter et sparsim punctate; scutello tri- 

 angulari, lecvi, nigro ; elytris fortiter punctatis, punctis sat con- 

 fertis, vix striis dispositis ; corpore subtus, abdomine, pedibus 

 antennisque rufo-nigris.

With the exception of P. Im-igata, this is the only species 

 that 1 know that is absolutely and entirely concolorous. From 

 that species it differs by its much smaller sise and the arrnngc- 

 nicnt of the punctures on the elytra; there is something like 

 the stria-like rows which generally obtain, though these are very 

 uneven and irregular. 



A single specimen from the collection of M. Cbrcvrolat. 



11. P. nigrOf n. sp. 



P. ovata, sat rotundata, punctato-striata, nigra; capite fovea inter 

 oculos armata transversa, rufo; thorace elytris angustiore, lateribus 

 ad basin |>nrallelis, antice rotundatis, disco sparsim et subtiliter 

 sed apud latcra fortius punctate, rufo, marginc basali late nigre ; 

 scutello Iccvi, nigro ; elytris thorace latieribus, punctato-strinlis, 

 punctis sequalibus, baud apicem versus obsolctis ; corpore subtus 

 tusco-nigro ; antennis pedibusque rufis vel rufo-fuscis.

I register this as the typical pattern of a new species, although 

 it is possible that it may ultimately be proved to be but a dark 

 variety : it has no such relationship, however, to any of the 

 species before me. 



The only example that I know was received by my friend 

 Mr. Baly from Port Natal, and is in his cabinet.
