NAUTIA, 243 



Synopsis of the Species of Nautia. 



A. Pronotum plainly divergent posteriorly, the transverse sulci deeply 

 impressed and the hind margin plainly but very obtusely angulate. 

 Antennas with the basal joints depressed, subensiform *. Pronotum 

 quadrifasciate with flavous. [Central America.] 



b. Larger (?, length 31 mm.) 1. flavosignata, Stal. 



bb. Smaller ( $ , length 27 mm.) . Serrations and tubercles of the pagina 

 black. [Costa Rica and northward.] 

 c. Tegmina and wings apparently as long as the abdomen .... 2. petasata, Rehn. 

 cc. Tegmina and wings abbreviate, not more than one-half the length 



of the abdomen 3. conspersipes, sp. n. 



A A. Pronotum subcylindrical, the transverse sulci less strongly impressed, 



the hind margin broadly rounded. Antennas either filiform or 



subensiform. Pronotum bifasciate with flavous. [British Guiana.] 



b. Hind femora comparatively slender, the pagina closely serrato- 



dentate. Hind tibiae reddish. Sides of face and cheeks below the 



eyes flavo-vittate [4. vitia-gena, sp. n.] 



bb. Hind femora rather robust, the paginse few and smooth, the upper 

 and lower edges of the outer disk marked with conspicuous blood- 

 red patches ; the genicular area black, with the exception of the 

 lobes, which are ivory-white. Hind tibiae olivaceous basally, 

 infuscated apically, the knees black [5. ornatipes, sp. n.] 



1. Nautia flavosignata, Stal. 



Nautia flavosignata, Stal, Syst. Acrid, i. p. 87 (1878) l . 

 Hah. Panama 1 . 



This insect is not known to the present writer. It in all probability extends farther 

 northward than its given habitat. 



2. Nautia petasata, Eehn. 



(Edalometopon petasatum, Rehn, Proc. Acad. Nat. Sci. Philad. 1905, pp. 418-420, figs. 19, 20 l . 



Hab. Costa Eica l , Carrillo. 



A specimen, possibly of this species, was seen by me during the month of March 

 at Juan Vinas, Costa Eica, but was not taken. It was resting upon the stem 

 of a climbing plant at the edge of a jungle and before it could be secured 

 succeeded in getting away among the almost impenetrable tangle of vines and 

 other vegetation. 



* This character is somewhat uncertain so far as N '. flavosignata and N. petasata are concerned, since both 

 Stal's and Eehn's types lacked antennas.
