George Hazen French in his " Butterflies of the Eastern United 

 States " published in 1886 gave an excellent description of Eudanius 

 ccllus, which he said ranges from West Virginia to the Gulf of 

 Mexico, and also occurs in Texas and Arizona. 



Regarding the occurrence of this butterfly near Coalburgh, W. Va., 

 W. H. Edwards wrote in 1888 : 



On one occasion, in June, I visited an unopened coal seam at least a mile 

 from any clearing, and at five hundred feet elevation above the creek, where the 

 coal was exposed to view, owing to its being between two ledges of rock, a little 

 sulphur-tinctured water trickled upon the base rock, and here were several 

 [Debis'\ Portlandia and that rare butterfly Eudamus Ccllus, in a cluster, eagerly 

 sucking. 



Samuel Hubbard Scudder in iSSy created the new genus Rliabd aides 

 for this species and a few others that he did not name. He gave an 

 exhaustive description of the imago but did not figure it. His descrip- 

 tions of the last stage larva and of the pupa are taken from Abbot's 

 colored figures. He said that it ranges from Georgia to Arizona, and 

 as far north as West Virginia and Kentucky ; he also listed a specimen 

 from Tallahassee, Fla., taken by Charles Johnson Maynard on April 

 17, and another from Putta on the Pacific slope of Mexico about 150 

 miles from Oaxaca. Scudder said that this species does not seem 

 to be so common as the other larger skippers of the same region and 

 notes that Abbot expressly called it rare. He said that Abbot bred 

 the butterfly on April 25 from a caterpillar that shut itself up in its 

 cocoon 3 weeks previously. He remarked that Abbot said it frequents 

 the sides of swamps, and that in his various manuscripts Brcwer'm 

 aquatica is given as the food plant, and upon this it is figured by 

 Boisduval and Le Conte. 



Dr. John Bernhard Smith in his " Catalogue of the Insects found 

 in New Jersey " published in the F"inal Report of the State Geologist 

 of New Jersey in 1890 said that Eudamus ccllus is taken rarely by the 

 Newark collectors. 



Eudamus ccllus was listed by Dr. Henry Skinner in his " List of the 

 Lepidoptera of Boreal America " published in 1891. 



WilHam Beutenmiiller in his list of the butterflies of the vicinity of 

 New York published in 1893 gave a brief description of Eudamus 

 ccllus and figured it ; he also gave a description of the caterpillar and 

 of the chrysalis, abridged from Scudder. He said that the food plants 

 are Convolvulaceae and cited Smith's record from Newark, N. J. 



Lt. Edward Yerbury Watson listed Rhahdoidcs ccllus in his revision 

 of the Hesperiidae published in 1893.
