DIAERETUS NIPPONENSIS, new species. 



Male. — Length 1.5 mm. Related to Discretus piceus Cresson from 

 which it may be distinguished by the costulse diverging from the 

 apex of the propodeum not at right angles to the median longitudinal 

 carina and by the nonprojecting petiolar spiracles. 



Female. — Flagel 11-jointed, costulse at right angles to the median 

 longitudinal carina on propodeum, otherwise very as in the male. 



Type.— Cat. No. 13495, U.S.N.M. 



Type-locality. — Japan. Received by the U. S. Department of 

 Agriculture, Bureau of Entomology, from Mr. G. Compere, under data 

 as follows: Cabbage aphis, Japan, 1906; G. Compere collector; No. 



15050. 



DOLICHOZELE, new genus. 



This genus has characters in common with Zele Curtis and Lepto- 

 zele Cameron. Compared with Zele Curtis this genus differs essen- 

 tially as follows: Clypeus broadly, shallowly emarginate, almost 

 truncate, hind ocelli larger than the anterior ocellus and nearer the 

 anterior ocellus than to each other or nearest point on eye margin 

 occiput immargined ; radius received by the stigma distinctly beyond 

 the middle, second discoidal cell completely closed, submedian cell 

 with a brownish spot on the median vein and on the submedian vein, 

 hind coxee shorter than the first abdominal segment ; first abdominal 

 segment as long as the next two combined, with its spiracles nearly 

 twice as far beyond the base as they are distant from each other. 



Type. — Dolicliozele Tcoebelei, new species. 



DOLICHOZELE KOEBELEI, new species. 



Female. — Length, 9 mm. Resembles Zele testaceator Curtis, but 

 differs as follows: Penultimate joint of m. p. distinctly longer than 

 the end joint, scape and pedicel combined hardly two-thirds the 

 length of the first joint of the flagel but about as long as the second 

 joint of the flagel, antennae 52-jointed, vertex with a blackish band 

 extending from eye to eye; stigma infuscated, propodeum with con- 

 centric arcuate striae; sheaths of the ovipositor about as long as the 

 second abdominal segment. Color in general dull stramineous not at 

 all reddish. 



Type.— Cat. No. 13496, U.S.N.M. 



Type-locality. — Pernambuco, Benito Province, Brazil. No. 168, 

 January 31, 1883; A. Koebele. 



Named for Mr. A. Koebele. 



HABROBRACON BENEFICIENTIOR, new species. 



The affinities of this species are with H. brevicornis (Wesmael). 

 Female.— Length 2.5 mm. ; sheaths of the ovipositor 0.5 mm. long. 

 From Marshall's description of H. brevicornis (Wesmeel) this differs
