is not mucli narrowed anteriorly (as compared with /?. exo- 

 htus, Sic), with a distinct imjnTssed medial line; with a (e\v 

 punctures near the side and alon;^ the front margin ; obscure 

 yellow, with a broad black stripe in the middle, widiMKid in 

 front and at the base, crossed in the middle by a broad trans- 

 verse band. Tiie elytra are yellow, irrorated with black 

 somewhat as in li. exoletus, but tiie black prevails to a mucli 

 greater extent, so that the discoidal area is almost entirely 

 black, leaving a narrow ^'ellow sutural line, and the yellow 

 marginal strijie very narrow and somewhat interrupted, 

 whilst the margin itself is more broadly black; the under 

 margins are yellow. The coxifi are marked with reddish 

 yellow, and the trochanters are almost entirely of this colour. 

 The anterior tarsi are very little incrassate, with narrow pads ; 

 the claws moderately long and slender, all but equal. 



Tiie only species in the Museum collection which closely 

 resembles this is one from Taiiiti, and which I believe to be 

 E. debilis, Sharp ; but that differs from the present species in 

 being less convex, lighter in colour, with more yellow legs 

 and antenn£B, whilst the prosternal process is black. Both 

 these species appear to be allied to R. pacijicus. 



Pectinicornia. 

 Charagmophorus, gen. nov. 



Insect parallel, convex. Mentum transverse, obliquely 

 narrowed in front, with the angles arcuately rounded, the 

 front gently emarginate. Antenna as in IScortizus. Eyes 

 less than one-half divided by the canthus, which in the male 

 is flattened and projecting laterally. Prosternal process pro- 

 jecting backwards, gently arched. Mesosternum sloping and 

 slightly concave. Anterior tibiaj denticulate. Intermediate 

 tibiae with one small spine. Posterior tibi£B without spines. 

 Tarsi rather long, the first four joints with a fringe of long 

 hairs arising from the ajiical margin of each joint. 



I think the aflinities of this genus are evidently with 

 Scortizus.
