80 ^Ir. G. L-wis on 



tlie head, imd "\vhicli is not so close to the marj^in; the 

 elytra, dorsal striae 1-3 complete, 4 shortened l)efore tlie 

 base, 5 somewhat shorter, sutural almost dimidiate; the 

 propygidiura has irregular, shallow, subocellate punctures, 

 chiedy on its sides ; the pygidium has large and deep punc- 

 tures, closely set at the base and apically is margined with a 

 rather wide and smooth, not elevated rim ; the auterior 

 tibiae are 4-dentictilate. 



The species in size is similar to P. vicinale, Lew,, but the 

 sculpture of the pygidium distinguisiies it from the other 

 known West-Africaa species. 



Hub. Angola. 



Omalodes optatus, sp. n. 



Ovatus, convexiusculus, niger, nitidus ; fronte minute punctulata, 

 in medio raodico sulcata; pronoto lateribus dense punctulato, 

 stria marginali ad angulos valida ; clytris striis 1 iutegra, 2 basi 

 abbreviata, apice punctis formata ; propygidio utrin(]ue grosse 

 punctate ; pygidio transverse puuctato, basi et apice lievi ; pro- 

 sterno baud striate ; mososterno utrinquo marginato ; tibiis 

 anticis 4-dentatis. 



L. 10-11 mill. 



The above is similar in outline to O.fclix, Lew. ; it is not 

 so oblong as O. mesthio, Lew., but its size agrees with that 

 Peruvian species. The fine punctuation of the head distin- 

 guishes it from felix ; the scutellar |)uncture is very distinct ; 

 the first dorsal stria is very fine on the apical half and has a 

 few fine punctures, the second is more marked posteriorly 

 but much shortened at the base, and close to the apical edge 

 it consists of three or four points only ; the propygidium is 

 almost impuuctate on the middle of its disc and the smooth 

 area widens out both before and behind ; the pygiilium, 

 ])unctures extend across the disc, leaving the apex and the 

 basal area smooth ; the anterior tibiiv are 4-deutate. 



Hab. Alto Parana, Argentina {Bertoni). 



Campylorhabdus {Tcinotarsus) pogr/ei, liar., 1870. 

 Harold's diagnosis of this species is : — 



"Ater, subnitidus, thorace dense punctulato, ad latora striolato, 

 elytris fortius ct dense subrugoso pnnctaiis, stria luunerali et 

 dorsalibus soptem extus carinatia. intorioribus aiitico abbroviatiR, 

 stria suturali autii-c abbreviata ; prostonio antico lobato-pro'liicto, 

 lobo medio cmarginato, mososterno margine antico subrotinulat.i 

 integro, non emarginato." 



L. 11-5 miU.
