Deridens Gn., is the common species, ranging from Canada to 

 Florida and west to the Mississippi. The ground color of the prima- 

 ries is white with a slight creamy tinge and on this the markings are 

 laid in black or bluish powderings, sometimes covering the wing very 

 completely ; but always leaving a considerable portion of the ground 

 color exposed in contrast. The lines of maculation are usually in- 

 tensely black, and the round black orbicular is usually one of the con- 

 spicuous features of the wing ; but it is rarely brown rather than 

 black, especially in old or worn examples. The connection between 

 the ordinary lines is always obvious and usually conspicuous and the 

 upper part of the median shade joins this connection, giving the effect 

 of a frame with light filling, centered by the orbicular. 



Sudena Sm., is a dull, smaller reproduction of deridens and may 

 not really be specifically distinct. It is from Miami, Florida, and as 

 a whole is less contrastingly marked than the preceding, the darker 

 portions more like washings than powderings. The orbicular is 

 hardly darker than ground and the lines are narrow and scarcely 

 contrasting. 



Dispulsa Morr. , is chiefly from Texas and is a very light ashen 

 gray species with rather scattering blackish powderings. The lines 

 are narrow, black, and there is no longitudinal connection between 

 them. 



Trisuloides patens Druce, is a Charadra which I had named basi- 

 flava before Dr. Barnes called my attention to the figure in the 

 Biologia (II, 509, pi. 96). It has been taken at Palmerlee, Cochise 

 Co. , Arizona, and is no doubt a member of our fauna. 



Decora Morr., and illudens Wlk., are hardly congeneric with the 

 preceding. 



Charadra sudena, new species. 



In all essential details of maculation like deridens Gn. It differs in its smaller 

 size in both sexes, in the narrower, much less contrasting transverse lines and it lacks 

 the conspicuous black center to the orbicular. The bar connecting the median lines 

 is narrow, brown or altogether wanting, and the s. t. line is much less irregular. 



Expands, 1. 36-1. 44 inches = 34-36 mm. 



Habitat. — Miami, Florida. 



Two males and one female from Dr. Barnes ; all of them a little 

 discolored, but otherwise in good condition.
