 I find that these genera cannot be kept sejiarate ; the species extinwria Wlk., 

 wliich 1 made the type of hochromodex, and its nearest allies are somewhat larger 

 and differently marked from the generally smaller and less consj)icnous species 

 which I at first referred to Spilocraspeda ; but, in the light of further experience, 

 the distinction can no longer be maintained. The species appear to be very 

 numerous, and in many cases closely allied and subject to considerable variation ; 

 the comparison of the underside of the wings affords the readiest means for 

 the determination of doubtful insects, of which the uppersides are almost exactly 

 identical.
