shining, about two and three fourths times as long as broad, rather 

 acute at apex; first marginal cell much smaller than second; ptero- 

 stigmal space open, large, long. 



Genitalia. — Female. — Genital segment very stout, relatively short, 

 rather acute at apex; dorsal valve large, abruptly acute at apex; 

 ventral valve more slender, equal in length to dorsal; pubescence 

 rather dense and long. 



Described from three females collected at Granada, Nicaragua, 

 by C. F. Baker. 



Type in author's collection. 



CARSIDARA DUGESH Loew. 



Figs. 148, 150, 374, 494. 



Carsidara dugesii Loew '86: 160. 

 Carsidara rostrata Crawford 'lib: 486. 



Close to gigantea, but distinctly smaller; color light brown, striped 

 similarly; vertex with sulcate depressions distinctly different (see 

 figure). Second marginal cell of forewing relatively larger; ptero- 

 stigma slightly thickened. Female genital segment more slender, 

 with a longer, more slender, and upturned termination. 



Described from three females (one not typically colored), from 

 Chinandega, Nicaragua (C. F. Baker). Judging from the similarities 

 in size, color, general appearance, and habitat, rostrata Cra^vford is 

 probably identical with Loew's dugesii, which was described from 

 Mexico (collector, A. Duges), on a species of Malvaceae. 



CARSIDARA MEXICANA Crawford. 



Figs. 147, 160, 385, 496. 



Carsidara mexicana Crawford 'lib: 487. 



Close to dugesii and possibly not a distinct species. Thoracic 

 dorsum with no indication of stripes; color uniformly flavous or 

 yellow. Vertex and thorax similar in structure and appearance; 

 pterostigma of forewing not thickened as above. 



Genitalia. — Male. — Anal valve large, almost as long as genital 

 segment, with a short, large posterior lobe, somewhat as Loew figures 

 for dugesii, but apical portion much shorter; forceps long, strongly 

 curved, obtuse at apex; second pair of forceps shorter, very acutely 

 pointed. 



Described from one male from Acapulco, Mexico (C. F. Baker). 



Type in author's collection. 



CARSIDARA CONCOLOR Crawlord. 



Figs. 146, 159, 375, 495. 



Carsidara concolor Crawford 'lib: 484. 



Similar to dugesii, but differing sharply in being whitish and more 

 or less pulverulent; thoracic dorsum not or very indistinctly striped
