23. LEUCOSPIS HOPEI Westwood. 



This species, said to be the most common Leucospis in Chile, is 

 represented by three specimens in the United States National Mu- 

 suem, two of which, female and male, were collected by E. C. Reed 

 in Chile ; the third specimen is a male of unknown locality. 



24. LEUCOSPIS APICALIS Cresson. 



Described from two specimens collected by Professor Sumichrast in 

 Mexico. Seen by the writer. Shape of body resembles that of 

 cayennensis, but is without metallic luster ; carina near hind margin 

 of pronotum prominent, angulate forward in median line ; ovipositor 

 reaches scutellum ; tips of wings broadly hyaline. 



Type. — Female, Cat. No. 1797 in the Academy of Natural Sciences, 

 Philadelphia. 



25. LEUCOSPIS ORIENTAUS, new species. 



In Schletterer's key this species runs close to affinis Say, from which 

 it differs in color pattern, absence of metallic luster on head, and 

 absence of spur on upper margin of hind coxa. It is also related to 

 japonica but differs in smaller size and in having yellow markings on 

 mesoscutum and scutellum. 



Female. — Length 8.7 mm. A medium sized hlach species, loithout 

 metallic luster, ahdome/n marked with a yellow hand across middle 

 and a hroad yellow hand in front and hehind, hind coxa without spur

 which covers carina near hind margin; short lateral lines on meso- 

 scutum above tegulae ; bilobed spot near hind margin of scutellum ; 

 a broad interrupted band on second abdominal segment, a narrow 

 band on fifth, a broad band on sixth, and two oval spots on apex ; a 

 triangular spot on metapleura ; upper margin of hind coxa tapering

 marking near base of hind femur, one horn of crescent extending 

 along upper margin and almost coalescing with spot at apex; base 

 and apex of hind tibia ; under side of front and middle tibiae and 

 apices of front and middle femora; tarsi. 



Head nearly as wide as hind margin of pronotum, face finely ru- 

 gosely punctate, covered with short pubescence; line from median 

 ocellus to level of clypeus 1.1 times interocular space ; malar distance 

 about one-fourth length of eye, clypeus sinuate with tooth in median 

 line; distance across scapal furrows about twice the distance from 

 margin of furrow to eye; vertex broad flat, postocular distance 1.4 

 times ocellocular ; occipital carina distinct above, disappearing before 

 reaching eye; antennae 12-segmented, first funicular segment about
