of the Suh-family Pclidnotinm. 275 



at the middle ; strongly punctured, still more closely and rugosely 

 at the sides : scntellum wider than long, punctured : elytra moderately 

 convex, with vague impressed longitudinal lines and fine scattered 

 punctures, which are larger and subseriate near the suture, coarsely 

 transversely foveate-riigose : sutural apex acute ; the apical callus 

 produced into a short acute spine : pygidium entirely clothed with 

 grey decumbent hairs and a few setse at sides and apex, closely 

 and finely muricate-rugulose, the apex narrowly rounded : breasts 

 and sides of abdomen rather thickly clothed with long grey hairs ; 

 last abdominal segment feebly p.mctate on the middle, the apex bi- 

 sinuate ; the 5th segment long. 

 Long. 20 mm. Lat. 11 mm.

A single $ example in the Royal Museum at Brussels, 

 bearing a label of Candeze, inscribed " Pdidnota armata." 



In colour, form, and general aspect, exactly like Pelidnota 

 (jranulata. 



Xenopelidnota, n. gen. 



(J . Head small, antennae 10-jointed : clypeus rather short, s' rongly 

 sinuately narrowed to the front, which is narrowly rounded, entire 

 and recurved ; mandibles narrow, projecting, entire at outer edge : 

 sides of thorax well rounded behind the middle, the hind angles 

 broadly rounded ; strongly margined at the base, the median lobe 

 distinct, and rounded behind : scutelluni transverse : elytra ridged 

 along the base, the outer margin with a feathery fringe ; sutural 

 apex simple : a small prosternal — but no mesosternal — process : 

 pygidium nearly vertical, densely, entirely, very finely, and intri- 

 cately, rugulose ; sparsely setose at sides and apex, the apex rather 

 broadly rounded : breasts pilose, the hairs fine and silky : 5th 

 abdominal segment long : legs moderately robust, but little differing 

 from the 9 j the claw-joints strongly toothed near the base : claws as 

 in Pelidnuta. 



5 . A little larger and of a more regularly ovoid form than the (J : 

 clypeus larger, but less sinuate at the sides, and less pointed in front : 

 mandibles broader : sides of thorax less rounded behind the middle, 

 the hind angles less broadly rounded : side margins of the elytra a 

 little explanate from the base to about one-third their length : 

 pygidium more declivous, more delicately rugulose, and less thinly 

 setose at the sides and apex : front (especially) and middle tarsi long 

 and very slender ; the tooth at base of the claw-joints very small, 

 obsolete in the anterior ones.
