Two species of tliis genus were described by Fairmaire 

 under the name of Pimc/opus (P. hithneri and annicoUis) , to 

 Avliich jjenus it is nearly related, diflcrinji; in the more tri- 

 anji;ular head, truncate clypens, and less abbreviated legs, of 

 which the front tibiie are four-toothed and the middle and 

 liind tibiiie mucii less dilated from base to apex and fringed 

 with long, not closely-set spines. 



I have seen several species, all from the islands of Papua 

 and Polynesia. The following is the typical species : — 



Papuana semistriata, sp. n. (PL IV. figs. 4, 5, 6.) 



Nigra vol piceo-nigra, nitida, pcctore parce rufo-hirto ; clypco 

 utrinquo acute angulato, subtilissimc punctulato, vertice utriuquo 

 rugoso ; prothorace antice retuso, rugoso, dorso medio acuminate, 

 angulis anticis acutis, posticis obtusis, basi trisinuato ; scutello 

 laevi ; elytris fortiter striatis, striis annulate punctatis, sutui'ali- 

 bus integris, reliquis postice abbreviatis, lateribus apicibusquo 

 fere laevibus ; mandibulis valde porrectis, extus parum profunde 

 uui-incisis : 



cT , capite cornu gracili, antice planato, apice obtuso, armato ; pro- 

 thorace postice lobo elevato, summo acumiuato, tuberculoque 

 utrimiue parvo, interdum obsoleto, munito, margine antico 

 lateribusque, spatio laterali carina breve arcuata delimitato 

 excepto, rugosis, superficie reliqua loevi (individuorum maxi- 

 raorum autem cornus basi antice etiam rugoso) ; pygidio 

 panctato, medio fere la^vi : 

 2 , capite tuberculo lato armato ; protboracis medio leviter acumi- 

 nate, antice rugoso; pj'gidio crebre et minute punctate. 



Long. 22-28 mm. ; lat. max. 12-14 ram. 



Hab. British New Guixea : Fly River ; Amboina. 



This is a larger species than P. hubneri and armicolUs, 

 Fairm., with more highly developed armature, althougli tlie 

 latter is, of course, subject to great variation. The femalp, 

 both in this and the following species, appears always to have 

 a retuse and rugose area in the anterior part of the pronotum 

 and a feeble but sharp elevation at the middle. The 

 mandibles, in both sexes, are much more produced forwards 

 and have only a single slight notch at the side. The elytra 

 of P. semistriata are coarsely punctate-striate, the striae.
