composition of the club. It is, moreover, a smaller, 

 less robust-looking insect than either of the others, 

 and measures about three-quarters of an inch in 

 length. The triangular white patches which are 

 so effectively arranged along the sides, and form 

 such a noticeable feature in the general appear- 

 ance of its larger allies, are also distinctly traceable 

 in the present species, although not developed in 

 so remarkable a degree. In form R. golstiHalis 

 may be described as long-oval, and in colour 

 reddish-brown, with the thorax and scutellum 

 thickly covered with long yellowish hairs. The 

 elytra, upon which can be traced very faintly 

 raised longitudinal lines, are but slightly punctured 

 in comparison with the thorax, and sparsely 

 pubescent. The legs are long and red. In their 

 internal anatomy the beetles of this genus are 

 remarkable for their great concentration of nerve- 

 centres. 



Summer chafers appear towards the middle or 

 end of June, and are said to be most destructive 



in those years when cockchafers are abundant, as 

 they follow up their ravages (Dr. E. Hofmann). 

 The larvae differ little in habit or appearance — 

 except in being slightly smaller — from those of 

 the Melolonthae : and the iniagos sally forth 

 towards nightfall, as do our other cockchafers, and 

 may be seen flying over grass-land or about i 

 shrubs, hedges, and similar situations, R. *ol- 

 gtitializ is a decidedly local chafer, and confined to 

 the southern portions of England and Wales. It 

 has been recorded from the Isle of Wight. South- 

 ampton, Dover. Hastings. Blandford, Swansea, and 

 one or two other places. Although generally a 

 scarce beetle, yet where occurring it is occasionally 

 found in numbers. At Eerndown (Dorset) in some 

 seasons these chafers appear in the greatest pro- 

 fusion, much to the delight and benefit of the local 

 poultry, which run them down and consume them 

 with avidity and evident relish.

Wings white. $ f .w. with a black spot at end of 

 disc, cell : midway between this and apex a black 

 spot touching the costa, and another just beneath 

 it. Along the ou. marg. a row of three or four 

 black spots. H.w. base dusky, a very narrow black 

 spot at end of disc. cell, o has the costal spots 

 continued to form a broken band reaching to in. 

 marg. : along ou. marg. a row of five spots. H.w. 

 with an ante-marg. row of dusky spots, and an 

 indistinct marginal spot at the end of each ner- 

 vule : ground colour somewhat dusky, owing to 

 the presence of finely scattered dark scales. U.s. 

 fringes of all the wings light brownish-pink. H.w.

 above, and sprinkled with black scales : otherwise 

 the markings of the upper side are repeated beneath

The upper side of J resembles P. bramcae, but 

 the black marking at the apex f.w. is more decided. 

 There is a short black line or elongated spot near 

 centre of wing. I have never seen a specimen 

 without at least a trace of this ; somet im es it is 

 well marked. H.w. have the costal spot some- 

 what darker than in P. Trrcu&ime. 2 differs con- 

 spicuously from that of P. brasgicae, first in the 

 extension of the black markings. The three black 

 spots seen on the f.w. in that species are enlarged 

 and coalescent, forming a conspicuous black patch.
