two others, one at the base of each hiteral valve : these valves 

 are also much shorter, ovate, and not attenuated, although end- 

 ing in an incurved hook. In the present ignorance in which a 

 true knowledge of the Lcpidoptera is involved, it is impossible 

 to say how far these dis^similarities may point out natural groups ; 

 it is therefore of the highest importance to the science such facts 

 should be noticed.
