I have seen the types of vigilans, senescens, and semisigna in the 

 British Museum. Mr. Butler refers semisigna Wlk., to senescens; but 

 in my notes I have referred it to vigilans, I think more correctly. The 

 specimens of crasis in the museum left me in doubt as to the synonymy; 

 but this doubt was removed by the specimens in the museum at Berlin. 

 Mr. Moeschler long ago sent me a specimen of his erdmani, labeled 

 crasis. We have herd a decidedly variable species, the gray form 

 being senescens Grt., and the crasis of the Berlin Museum. The reddish 

 form is vigilans Grt., and. erdmani Moeschl., with semisigna Wlk., some- 

 what intermediate but nearer to vigilans. In maculation the median 

 lines vary in distinctness and the ordinary spots in the amount of black 

 surrounding them. The species is not common, and I think I have 

 seen nearly all the specimens in the American collections.
