The following is another new species nearly related to 

 P. abbreviatits, but of elongate form. 



P. exiguus, sp. n. 



Parvus, angustus, apterus, testaceus, elytris totis, metasterni 

 lateribus abdomineque nigris ; capite prothoraceque immaculatis, 

 oculis haud prominentibus, prothorace elongato, lateribus antice 

 leviter curvatis, parte quarto postico parallelis, disco convexo ; 

 scutello testaceo ; elytris a basi ad post medium leviter ampliatis, 

 paulo elongatis sed apice valde incurvato-truncatis, humeris fere 

 obsoletis, costis fortiter elevatis, quam intervallis latioribus. 



Long. 12 m.m.

This species, one of the smallest of its genus known 

 to me and the smallest of the African species, is quite 

 unmistakable from its rather peculiar form. Although 

 one of the wingless insects with sloping shoulders and 

 emarginate extremity to the elytra, the latter are not of 

 the short and broad pattern generally distinctive of these 

 apterous forms. Both thorax and elytra are long and 

 narrow and the elytral costse are very broad and 

 prominent. 



Specimens collected by M. Guilleme near the western 

 shores of Lake Tanganyika have been kindly presented 

 to the Museum by M. Rene Oberthur. 



P. pallidepunctatus, sp. n. 



Apterus, testaceus, prothoracis marginibus antica et postica, 

 elytris, mesosterni partibus abdomineque nigris, genubus lasvissime 

 fusco-plagiatis, elytris punctis humeralibus et discoidalibus pallide 

 fulvis ornatis ; prothorace paulo elongato, antice et postice nigro, 

 marginibus nigris medio paulo intrudentibn s, lateribus antice parum 

 rotundatis, postice fere parallelis ; elytris brevibus, humeris fere 

 obliteratis, lateribus regulariter curvato-ampliatis, postice conjunctim 

 arcuate truncatis, macula humerali subrotundata extus epipleuras 

 tingente et secunda discoidale punctiforme pallide flavis, margine 

 apicali vix perspicue testaceo-tincta, costis angustis. Long. 14 m.m.

This insect, found by Mr. R. Sheppard and kindly sent 

 to me by Mr. G. A. K. Marshall, is sharply separated 

 from the species most nearly related to it by the black
