ITO Arthur M. Lea : 



convex in middle, sides distinctly narrower than behind the 

 fovea, each side with a feebly raised and indistinct ridge ; under 

 surface less excavated than usual, but the excavation joining on 

 to a very large one on nietasternuni. Hind coxae each with a 

 strong triangular tooth at right angles to the general level ; 

 femora fairly stout; hind tibiae inflated towards apex, the 

 front pair less and the middle pair still less noticeably so. 

 Length If mm. 



$ • Differs in having the abdomen gently convex on the under 

 surface, the apex of the metastemum very feebly impressed, 

 and the hind coxae unarmed.

 Museum). 



The antennae are very wide as in raffrayi, but not of the 

 same shape, and not impressed on the upper surface ; the latter 

 character will also distinguish it from aurifluus. Asper is de- 

 scribed as having the prothorax nonfoveate. 



Seen from the sides each antenna appears to have the basal 

 third thin, with the rest swollen, rather more noticeably on the 

 under than the upper surface. From some directions the sides 

 of the prothorax almost appear to be ridged. The impunctate 

 spot on each elytron is distinct on one specimen, fairly distinct 

 on another, but practically absent from a third. The large 

 spurs on the hind coxae of the male appear at first to be part 

 of the metasternum. The apical segments of the male are so 

 strongly drawn inwards that the pygidium appears to be in the 

 exact middle of the under siirface of the abdomen. 



Articerus Mastersi, n.sp. 



$ • Colour and clothing much as in Raffrayi. 



Head wide, flat and densely punctate, without median im- 

 pression. Antennae slightly longer than head, wide and 

 flat, base narrow, then strongly inflated to middle, and 

 thence feebly diminishing to apex, with a distinct but rather 

 shallow depression in middle. Protliorai about once and one- 

 third as wide as long, sides almost parallel, with a large but 

 rather shallow medio-basal fovea ; punctures as on head. Elytra 

 with dense punctures, becoming sparser on disc ; sutural stria
