EpitrU.~\ PHYTOPHAOA. 



f, with the shoulders almost rounded, and the general punctuation 

 eonndentblj finer, the interstices on the elytra being evidently narrower, 

 and the pubescence longer; it may be easily known by its colour, \\liich 

 is usually black with two rufo-testaceous spots on each elytron, on 

 near tho base, and the other at apex; these, however, are variable, and 

 they occasionally meet and cover nearly all the elytron ; sometimes the 

 b.-isul spot is absent. Allard considers that this species may be a variety 

 of the preceding, but they are really very distinct. L. 1|-1| mm.

This genus, taken iu its widest sense, as including PlerfrofCfJitt, Redt,, 

 contains about one hundred and forty-five species, of which more than 

 half have been described since the publication of the Munich catalogue 

 in 18/6 ; they are widely distributed throughout the world, representa- 

 tives occurring from Siberia to South Africa, and also in the Malay 

 Peninsula and the Australian region, India, Central and South 

 America, &c. ; they are distinguished by the fact that the intermediate 

 and posterior tibiae are furnished with a tooth on their outer side 

 between middle and apex, or to describe it more accurately, are 

 emarginate on their outer side before apex, both extremities of the 

 einargination being raised into a tooth ; twenty-four species are recorded 

 as European, of which, however, ten belong to the genus Plo-trosceh'*, 

 which is here regarded as separate ; the genus Cflcetocneina proper may be 

 known by the large head, which has no elevated keel on forehead, 

 the large labrum, and the more or less confusedly punctured elytra ; 

 there are five British species, which may be distinguished as 

 follows : 



I. Head behind eyes finely punctured ; thorax thickly, 



finely, and not deeply pnuctured. 

 i. Form elongate oval ; head closely punctured, duller. 



1. Upper surface always dark blue; average sire 



smaller ............... C. BUBCCERri.KA, Knt*. 



2. Upper surface bronze or greenish-bronze ; average 



size larger .............. C. ARIDULA, flu! I. 



ii. Form short oval, rather broad ; head diffusely 



punctured, at all events in centre, more shining . . C. CONFU8A, 7/</A. 



II. Head behind eyes comparatively strongly pinu-tnreil ; 

 thorax thickly and rather strongly aud deeply 



punctured. 

 i. Antenna: with the base unicolorous red ; colour 



bronte ................ C. HORTfNSls. fotirc. 



(<,r<cMla, Payk.) 

 ii. Antenna' with the upper surface of the first joint 



and apex of the second dark ; colour blue or bluish- 



trreen ................ C. SAHJ.BFRGI,
