This species is widely distributed throughout the Eastern and 

 Atlantic States, and is found as far west as Texas. Having exam- 

 ined the type of Dr. Fitch, I am enabled to refer it to this species. 

 A specimen sent to Dr. Signoret of Paris was also identified by him 

 as Aetlius Robinsonii Fitch.

 Mass. 



The females usually have a sublunate white spot near the postero- 

 exterior corner of the corium. Mr. Say appears not to have known 

 the female of this species, for he makes the absence of the white spot 

 a specific difference. 



It spreads over almost the whole country east of the great basin, 

 and extends into Canada and Mexico.
