Range. Almost universal, but not found in Madagascar, Aus- 

 tralia (except the widely-dispersed Anomala antiqua), New Zealand, 

 or S. America west of the Andes. 



Form extremely variable, sometimes short and globose, some- 

 times very long and narrow, with stout, moderate or very long 

 and slender legs. The surface may be extremely smooth and 

 shining, or strongly sculptured and opaque, and sometimes 

 entirely clothed with hair. The membranous external fringe of 

 the elytra is always distinct and in some species considerably 

 developed. The clypeus is transverse, rounded or straight in 

 front, rarely at all excised and never produced or rostriform. 

 The eyes are prominent and sometimes very large. The pro- 

 thorax is transverse, generally slightly lobed' and never excised 

 in front of the scutellum, and with or without a complete marginal 

 stria at the base. The prosternura is not, or only very little, 

 elevated behind the front coxa3 ; in a few species (e. g. A. anopunc- 

 tata and cenigma) it forms a small acute vertical process, but is not 

 bent forward between the front cox as in the genus Mimela. The 

 mesosternum is most commonly not produced between the middle 

 coxa?, but occasionally forms a process of varying shape, some- 

 times very short and rounded (A. ebena), sometimes slender and 

 sharply pointed. The legs are very variable in development ; the 

 front tibia is armed with one, two, or three teeth and bears a 

 single spur at the base of the tarsus ; the middle and hind tibiae 

 may be long or short, but are generally spinose externally, and 

 each bears two terminal spurs ; the tarsi are generally moderately 

 long, the claws always entire upon the hind feet, the longer one 

 of the front feet, or of the front and middle feet, cleft, or all 

 entire. The labrum is bilobed, not prominent, horizontal in 

 position and not presenting a face at right angles to the clypeus.
