present I preFer, instead of making yet more genera, to retain all 

 these forms in the great genus Adoretus. 



Tlie very numerous species of Adordus are almost all dull- 

 coloured inconspicuous insects. With few exceptions they appear 

 to be nocturnal \\\ their habits, emerging at night to feed upon 

 foliage. Several of the common Indian species have been found 

 in considerable numbers feedhig upon roses, cannas, vines, man- 

 goes, and other cultivated plants, while their larvae have been 

 found in the soil at the roots of these and other plants, and the 

 adults also conceal themselves beneath the surface soil during 

 the day. They are therefore not often seen, in spite of their 

 abundance, except when attracted into houses by light.
