above ; antennae broken at third segment ; scape more than twice as 

 long as wide, first funicular segment 1.2 times pedicel. 



Pronotum contiguous punctate without transverse carina ; meso- 

 scutum about 1.5 times length of pronotum in median line; scutellum 

 broadly rounded behind; foveae of metanotum contain parallel 

 ridges with depressions between, hind margin of metanotiun finely 

 punctate laterally almost to edge, which is narrowly polished, apex 

 crescent shaped, slightly projecting over propodeum, with upturned 

 edge; propodeum about equal to metanotum in median line, much 

 longer laterally; spiracular area covered with long silvery hairs. 

 Hind coxa with outer surface entirely punctate, a broad, thin blunt 

 spur on upper margin toward apex ; hind femur 1.8 times as long as 

 wide, basal tooth large, margined and followed by eleven smaller 

 teeth, the first six well separated from each other, the rest becoming 

 crowded. Fore wings subhyaline, clouded along costal margin and 

 toward apex with paler streak through central area; hind wings 

 paler. 



Abdomen a little longer than head and thorax together, seen from 

 above constricted in fourth tergite, swollen in sixth, and compressed 

 toward apex; seen from side view abdomen is straight dorsally and 

 broadly rounded at apex; second segment of abdomen is nearly 1.3 

 times as long as wide, with two furrows above, which diverge toward 

 base and are separated by a dull median carina; third, fourth, and 

 fifth segments short, sixth shorter than second segment. Ovipositor 

 reaches nearly to middle of propodeum. 



Described from one female loaned by Cornell University. 



Type. — At Cornell University. 



Habitat. — South America: Argentine, La Rioja (E. Giacomelli). 



10. LEUCOSPIS EGAIA Walker. 



Lencospis egaia Walker, Roman, Arkiv. f. Zool., vol. 12, no. 19, 1920, 

 pp. 8-9. 

 Type of this species a female collected by Mr. Bates at Ega, Brazil, 

 is in the British Museum. The United States National Museum con- 

 tains one female from Obidos, Amazonas (H. Rolle), determined 

 from literature as this species. 



11. LEUCOSPIS BIGUETINA Jurine. 



One female in the United States National Museum obtained through 

 exchange from Cornell University (Lot 326. Sub. 2). Abdomen 

 shown on plate 3, figure 18. 



12. LEUCOSPIS FUUGINOSA, new species. 



In Schletterer's key this species runs close to micrura Schletterer, 

 but differs in shape of face, comparative length of antennal segments, 

 form of hind femur and character of femoral teeth.
