B. eorata, Mirsh. Smaller than the preceding, and not so regular 

 in outline, the thorax being evidently narrower than the ehtra; it is 

 also more depressed and rather narrower, and may be known by its bronze 

 mliiiir and the stronger punctuation of the sides of the head; the rows 

 of punctures on the elytra, moreover, are finer, and the punctures are set 

 more closely together. L. lf-lf mm. 



On Rnbun, hawthorn, and low plants ; on chalky hill-sides in woods, &c. ; locally 

 c .niiiKMi ; London district, Kent, Surrey, and smith coast generally distribute*! ; 

 very abundant in the Isle of Wight at the end of April and beginning of May, nml 

 I', mud on almost every hawthoru hedge and bush in the south of the island ; Henley ; 

 Hereford (Blatch) ; Findern, near Repton (Uarneys) ; Northumberland and Durham 

 district, "Helton Hall,, near Belford" (\V. B. Boyd) ; I feel, however, somewhat 

 doubtful as to the latter record. 



SPHJERODER1VIA, Stephens. 



In its subhemispherical convex form this genus resembles Apteropeda, 

 but may at once be known by having the elytra confusedly punctured ; 

 the mouth parts, moreover, are covered, or almost covered, by the 

 prosternum, the posterior tibiae are not denticulate externally, and the 

 spur at their apex is absent or obsolete ; our species are entirely rufo- 

 testaceous ; the total number of species at present known is about forty, 

 which are very widely distributed, representatives occurring in India, 

 Japan, Ceylon, Africa, the Malay Archipelago, North and South America, 

 the Australian region, &c. ; three only inhabit Europe, of which two are 

 found in Britain ; they are very closely allied, but may be distinguished 

 as follows : 



I. Average size larger ; form more hemispherical ; tibiae slightly 



curved S. TB8TACEUM, /'. 



II. Average size smaller; form a little more oblong; tibia? 



almost straight S. CARDCI, '/'////. 



S. testaceum, F. (centaurece, W. C.). Subhemispherical, shining, 

 entirely rufo-testaceous, except the eyes, which are black ; head small 

 with distinct frontal tubercles, vertex scarcely punctured, antennae long, 

 very gradually and slightly thickened towards apex ; thorax very trans- 

 verse, gradually narrowed in front, sometimes very obsoletely and 

 scarcely visibly punctured, sometimes distinctly punctured ; elytra with 

 the shoulders rounded, but slightly marked, sparingly and very finely 

 punctured, the punctures towards the sides being arranged in more or 

 less distinct rows. L. 2^-4 mm. 



On thistles, &c. ; common and generally distributed throughout the kingdom. 



S. cardul, Gyll. (testacea, W. C.). Extremely closely allied to the 

 preceding, but not quite so round, and a little more oblong; the thorax 

 is a little leas compressed at apex, and has the sides less rounded and the, 

 anterior angles more prominent, and in the mule the first joint of thu
