nilin/inosa as a variety, since it can be readily separated by the 

 characters given in the key and habitually occurs in drier situa- 

 tions than does typical aliiiticea. 



The distribution of ri<l>i</inosa is given by Scudder (ISOOc, 

 4<il') as "The entire Atlantic Coast of the United States from Cen- 

 tral Massachusetts to Key West, Fla.. and in the interior, east of 

 the Great Plains, from as far north as Iowa and Minnesota to the 

 Gulf, extending into Mexico and even farther south."

Ormond, Gainesville, Miakka and Dunedin, Fla., Oct. 11 Apr. 

 4 ( W. 8. B.). This large and handsome species is not known from 

 Indiana and is apparently scarce in Florida in winter and spring, 

 having been noted only on three or four occasions. About Dune- 

 din it was first seen on Hog Island, where three or four individ- 

 uals were noted on the foliage of the Florida button-bush, Couo- 

 <-<ir/niK crccta L., just inside the fringe of black mangrove. On 

 two other occasions a few individuals were flushed from high 

 weeds and willows along the margins of a moist hammock. The 

 flight of the male is prolonged and both sexes, when flushed, al- 

 ways alight on shrubs or trees some distance above the ground. 

 A single female from Ormond is of the unstriped variety with the 

 Icgniina vaguely flecked with fuscous, thus resembling >s'. a. rn- 

 1t ic/'ui osa but much larger. X. oltftcura has been recorded from nu- 

 merous other Florida stations betAveen Jacksonville and Key 

 Largo, but was nowhere found in large numbers. 



The known range of Hie species extends from Baltimore, Md., 

 south and southwest in the coastwise states to Texas and Mexico. 

 According to Scudder it is found throughout the latter country;
