Homoscarta, but the head is much more produced than in Homoscarta^ 

 and the species are much less robust. 



In T. coriacea (Stil), the male pygofer and its lobes, not illustrated 

 here, are like those of T. cartwrighti, new species.

Length of male 11.5-15 mm. Head with a distinct M-shaped eleva- 

 tion bordering posterior margin, clypeus with muscle impressions not 

 very distinct. Forewing with clavus and basal portion of corium punc- 

 tate, with a claval crossvein. Hindlegs with length of first tarsomere 

 about equal to combined length of second and third. Male pygofer 

 with posterior margin oblique and slighdy concave; style acute at 

 apex; paraphyses each with two short branches near midlength, the 

 apical half slender and aciculate; aedeagal shaft slighdy decurved at 

 apex, with a pair of anteapical lateral processes which appear lyriform 

 in caudoventral aspect. Color sordid brown, with red (type) or yellow 

 spots on pronotum, with an interrupted median scutellar line, a 

 number of spots of various sizes on forewings, markings on clypeal 

 muscle impressions, on midline of clypellus, and spots on fore- and 

 middle femora, yellow. 



Holotype male, Turrialba, Costa Rica, May 31, 1951 (O. L. Cart- 

 wright), and two additional male specimens from Panama (USNM). 

 The Panama males are considerably larger than the type, but the 

 genitalia appear identical. 



This species is named in honor Dr. O. L. Cartwright of the U.S. 

 National Museum, who collected the type.
