The following are descriptions of two new species of Eudejeania 

 recently secured by the writer in the high Andean region of central 

 Peru : — 



Eudejeania punensis X. sp. 



Length of body to ends of spines, 1-1 to 16 mm.; of wing, 11.5 to 13.5 mm.; of 

 palpi, 3.5 to 4 mm.; width of abdomen, 7 to 8 mm. Fifty-two females and one male, 

 Pachacayo valley, about 12,000 feet, in puna region about half way between Oroya 

 and Jauja, Peru, March 27 and 28, 1913, on flowers of Viguiera-Wke composite. 

 The immense preponderance of the females is worthy of remark. 



Differs from Eudejeania yiigra T. by its much smaller size and by the following 

 colorational characters : — Legs with their spines, palpi and first two antennal joints 

 rust-yellow, the second antennal joint more or less slightly smoky on base. Wings 

 only lightly smoky, the veins rust-yellow giving the wing bases a distinct yellow 

 tinge. Parafrontals dusky olive. Occipital pile pale brassy. Thorax and abdo- 

 men dark brown to black, showing smoky pollinose on anal segment in oblique 

 view and somewhat less so on third segment.
