These specimens differ from aequale 

 in having the carina very low, it being 

 scarcely more than an elevated line ; 

 in having less tumid cheeks and occi- 



and the hind femora lack fuscous in the 

 basal part of the tibial sulcus. The 

 coloration is markedly rosaceous in 

 tint. They are so nearly intermediate, 

 both in coloration and pronotal struct- 

 ure, between the forms of series I and 

 II with least developed carina that 

 their correct position is open to a doubt 

 which could be readily settled by ex- 

 amination of more material.
