Drake: The Genus Dicysta Champion. 273 



Brazil, in Carnegie Museum. This species is so very distinct that I 

 feel entirely justified in describing it from a single example. 



4. Dicysta smithi n. sp. 



Differs from D. vitrca Champion and the new species described 

 above by its much narrower form, the biseriate costal area, and the 

 pyriform shape of the hood. The median carina is not strongly 

 raised nor areolate between its inflated posterior process and hood, 

 and, moreover, it is connected with the latter structure at the base. 

 Length 3.34 mm. ; width 1.32 mm. 



Moderately elongate and oblong. Head with three porrect frontal spines, 

 the median a little longer than the lateral ones and not quite as long as the 

 first antennal segment. Rostrum reaching to the meso-metasternal suture. 

 Antennje long and slender, the third segment slightly curved and two and two- 

 thirds times the length of the fourth ; fourth segment a little swollen, clothed with 

 numerous short hairs, a little more than twice as long as the first and second 

 segments taken together. Hood moderately large, pyriform, its height slightly 

 greater than its length and one and two-fifths times its width. Posteriorly 

 bladder-like process of median carina a little higher and longer than the hood, 

 rather broadly rounded above, the sides somewhat compressed and much nar- 

 rower than the hood. Paranota moderately wide, not strongly reflexed, mostly 

 triseriate, the areola along the outer margin much larger than the others, 

 Pronotum coarsely punctate, shining. Wings considerably longer than the 

 abdomen. Elytra widest a little in front of the middle, broadly rounded at 

 the tips ; costal area moderately wide, biseriate, the areolae large and mostly 

 pentagonal ; subcostal area with three rows of areolse at its widest place ; tumid 

 elevations moderately large, occupying most of subcostal and discoidal areas. 



General color testaceous, the areola hyaline and somewhat iridescent. 

 Legs and antennae yellowish brown, the apical segment of the latter entire 

 brown. Pronotum brown. Body beneath dark brownish, slightly tinged with 

 red, the eyes black. A few nervures on tumid elevation and a clouded spot 

 in sutural area fuscous. 



Described from three females, taken during July by Mr. and Mrs. 

 H. H. Smith at Chapada, a small village of Matto Grosso, Brazil, 

 about 25 miles E. N. E. of Cuyaba. Type in Carnegie Museum ; para- 

 types in Carnegie Museum and author's collection.
