below ; radial cell attaining the wing tip ; second section of the radius 

 one-third longer than the first, and one-third as long as the third. 



Bred by Mr. C. A. Frost from sumach twigs infested with 

 Liopits alpha Say ; Framing-ham, Mass., May 1906. 



The present species belongs in Cceloides as defined by Schmie- 

 deknecht in his "Hymenopteren Mitteleuropas" (p. 516) although 

 it is evidently quite different from Cceloides as understood by 

 Ashmead, who places the genus in the Braconinse. Cceloides 

 initiator Fabr. of Europe lias been bred from several genera of 

 Cerambycidse, but to judge from the description of that species 

 as given by Nees it can no longer be included in Cceloides on 

 account of the triangular space at the base of the second abdomi- 

 nal segment.

Through the kindness of Mr. C. W. Johnson of the Boston 



Society of Natural History I have received a female of this 



interesting species, bred by Mr. C. A. Frost from Liopits alpha 



Say contained in sumacb twigs. Ashmead's types were obtained 



from the same plant infested by this same beetle, so there can be 



no doubt that it is the host of the Cenocoelius. 



FAMILY CLEONYMIDiE. 



Cheiropachys obscuripes sp. now 



Length 2.3 mm. Metallic green, the head more coppery and the 

 metathorax more bluish ; abdomen with an obscure honey yellow band 

 near the base ; wings with two costal inf uscated spots. Head two and 

 one-fourth times as broad as thick ; ocelli in a curved line, the lateral 

 ones somewhat nearer to the median ocellus than to the eye margin. 

 Eyes rounded ovate, bare. Antenna? inserted near the middle of the 

 eye?. Malar space half as long as the eye, without furrow. Clypeus 

 nearly truncate, with a slight median emargination. Mandibles stout, 

 their apices broad. Antennas with two ring-joints ; 13-jointed, counting 

 the short oval club as three jointed, although this really appears two- 

 jointed, with a single suture. Scape honey yellow, somewhat flattened 

 and curved, as long as the first three joints of the flagellum together; 

 pedicel as long as the first flag-ellar joint, the latter nearly twice as
