new Species of IlisteridaB. 259 



Pehrurus fraudator, sp. n. 



Breviter ovalis, supra depressus, nigro-aeneus, nitidus, elytris 

 viridi-caeruleis, pygidio rufo ; fronte depressa, punctulata, 

 lateribus marginata; pronoto lateribus pnnctato ; elytris striis 

 1-4 integris geminatis, 5 suturalique simplicibiis ; propygidio 

 parce punctato ; pygidio convexo, tenuissime punctulato ; meso- 

 sterno bisiniiato marginato ; tibiis anticis 6-denticu1atis. 



L. 4|-o| mill. 



This species is very similar to glaucopterus , Mars., from 

 Natal, but the thorax has a wide antescutellar space smooth, 

 the inner subhumeral stria is somewhat irregular and broken 

 anteriorly, the fifth dorsal stria is single, with a short apical 

 appendage parallel to it but not joined. 



There are only ten species of this genus known and they 

 all appear to be local and restricted in their distribution. 

 The measurements given for this and densistriatus show that 

 specimens vary much in size.

Pelonirus densistriatus, sp. n. 



Breviter ovalis, supra depressus, niger, subopaeus, pygidio apice 

 obscure rufo ; froute punctulata ; pronoto lateribus sat fortiter 

 punctato, disco la^vi ; elytris striis 1-5 dorsalibus geminatis 

 interstitiis striatis, suturali in medio furcata ; pygidio apice 

 utrinque compresso, punctato ; prosterno lobo antico grosse 

 punctato ; tibiis anticis denticulatis. 



L. 3-4 mill. 



Oval, somewhat short, depressed above, black and a little 

 opaque ; the head, forehead impressed, surface punctulate 

 and margined laterally ; the thorax punctured at the sides, 

 disc smooth, scutellar puncture bilinear, being divided in the 

 middle, marginal stria complete, posterior rim punctured 

 opposite the second and third dorsal stride ; the elytra, 

 dorsal strise 1-5 geminate but not very distinctly joined at 

 the base, the outer pairs have interstitial striae which render 

 the true striae less apparent ; the sutural stria is not gemi- 

 nate, but it has a short branch on the discal area obliquely 

 pointing outwards, the suture itself is finely marginate; 

 the propygidium has punctures of varying sizes, which are 

 largest and more close on the anterior half ; the pygidium, 

 the anterior portion is slightly convex and smooth, and from 

 the middle of this area runs a smooth carina to the apical 

 margin, on each side of the carina the pygidium is com- 

 pressed, the surface distinctly punctured and obscurely red ;
