 Northern India (mihi). 



Life-History. — Beetles were reared in the Indian Museum in July 

 1894 from a batch of pupae obtained from ornamental bushes in 

 the Museum compound. Both larvae and beetles feed upon the 

 scale insect, Icerya asgyptiacum. 



The insect was found by the writer in April 1902 feeding 

 upon the scale insect Monophlebus stebbingi in company with 

 Vedalia guerinii, the latter being by far the most numerous of- the 

 two. Only the adults of the roseipennis were taken, though it is 

 probable that larvae were also present upon the sal trees upon which 

 the Monophlebus was feeding.
