to the apex ; hypopygium short and not very narrow, pro- 

 jecting very little beyond the dorsal segment and truncate 

 at the apex. Third abscissa of the radius a little longer 

 than the second ; first recurrent nervure received at two- 

 thirds from the base of the second cubital cell, second at 

 one-fifth from the base of the third cubital cell, the division 

 of the first cubital cell incomplete. 



Black; the mandibles at the base, the clypeus (except a 

 narrow transverse line near the apex), pronotum (except a 

 narrow transverse band on the sides, not nearly reaching the 

 middle), a large spot on the mesonotum, tegulse, scutellum 

 (except the margins), postscutellum, a broad, undulating, 

 transverse band on the median segment, mesopleurfe, a band 

 broadly interrupted in the middle on dorsal segments 2-6, a 

 spot on each side on tlie first dorsal segment, a nan-ower 

 band on ventral segments 2-4, the femora beneath and the 

 tibiae above bright yellow ; tibise beneath and tarsi testaceous 

 brown. Wings hyaline ; nervures testaceous at the base,

On a second specimen the yellow markings, especially on 

 the median segment and abdomen, are more developed than 

 in the specimen described. 



Genus Eucyrtotuynnus, Turn. 

 Eucyrtothijnnus, Turn.Wytsman's Genera Insectonim, cv. p.2-J (1910), 

 In this genus should be included several species placed 

 provisionally in Elaphroptera in my paper, Zool. Jahrb. 

 xxix. 2, 1910, viz. E. rosenbergi, E. anisitsi, E. acuttdentata, 

 E. obfuscata, and, with much doubt, E. mapire7isis and 

 E. inferna. E. steinbachii might be included in the genus 

 Chrysothyymus provisionally, which might also include 

 E. bogotana, E. mhnula, and probably also E. deserta and 

 E. desponsa, but none of them are very near the typical 

 species C inca, Turn., of which the female is still unknown.
