Ischnoptera iiisequalis Saussure and Zehntner. 



1893, Ischnoptera inasqualis Saussure and Zehntner, Biol. Cent.-Amer., Orth., 

 i, p. 36, tab. vi, figs, 14-17. [North Mexico and Texas.] 



One male ; San Carlos, Costa Rica. (Schild and Burgdorf.) 

 [U. S. N. M.] 



This specimen is somewhat smaller than the male measured by 

 Saussure and Zehntner, but otherwise agrees perfectly with their 

 description. This record considerably extends the range of the 

 species. 



Ischnoptera rubiginosa Walker. 



1868, Ischnoptera rubiginosa Walker, Oatal. Blatt. Brit. Mus., p. 121. [Sant- 

 arem. Brazil.] 



Two females; Bartica, British Guiana. May 4 and 7, 1901. 

 (R. J. Crew.) [A. N. S. Phila.] 



One of the two specimens examined is slightly larger than the 

 other, but both seem referable to Walker's species. They agree 

 perfectly with his description except that the costal stripe on the 

 tegmina instead of extending " to three-fourths of the length," is 

 very much weakened and indistinct beyond the middle. 



Ischnoptera consobrina Saussure. 



1862, I[schnoptera] consobrina Saussure, Kevue et Magasin de Zoologie, 2e ser., 

 xiv, p. 170. [No locality.] 



One female ; Mexico. [U. S. N. M.] 



This specimen is considerably smaller than Saussure and Zehnt- 

 ner's measurements, but is clearly referable to this species. 



Ischnoptera jamaicana n. sp. 



Types : $ $ ; Portland, Jamaica ( 9 ), and Jamaica ( 2 ). 



Apparently closest allied to I. divisa Saussure and Zehntner,* 

 but differing in the much paler coloration, the more elongate pro 

 notum, and the triangular supra-anal plate, With the numerous 

 West Indian species no close relationship appears to exist. This 

 species belongs to the section of the genus with the medio-discoidal 

 area not exceeding the medio-uluar in width. 



9 . — Size rather small ; form elongate-ovate. Head with the interspace between 

 the eyes very broad, but slightly narrower than that between the ocelli, subequal ; 

 eyes elongate pyriform ; antenna} slightly exceeding the body in length; lower 

 portion of face somewhat flattened. Pronotunj subtrigonal in outline; anterror 

 margin truncate, posterior margin very broadly rounded, postero-lateral angles
