testaceous, with a narrow annulus near base and the apical third, 

 dusky; abdomen wholly black, except the membranous margins 

 along the 1st tergite which are dark reddish-brown.

 the shorter abdomen, and the entirely black posterior femora. 



Type locality. — Colorado. 



Type.— Cat No. 24003, U.S.N.M. 



Described from 1 female specimen labeled " Colo. 1080, Collection 

 C. F. Baker," and 4 male specimens from the Baker Collection, bear- 

 ing the following numbers : Colo. 2076 (2 specimens) ; Colo. 1330 ; 

 and Colo. 1329. 



18. MICROPLITIS MELIANAE Viereck. 



Microplitis meUanae Viebeck, Proc. U, S. Nat. Mus., vol. 40, 1911, p. 1S5. 



Type.— In the United States National Museum. 



Iowa; Kansas; Illinois; Tennessee; New York; Canada. 



Eosts.-Meliana alhilinea Hubner (Viereck) ; Cirphis unipuncta 

 Haworth. 



Cocoons.— Ahout 3.5 mm. long ; brown ; not ribbed ; evidently gre- 

 garious, but not cemented together. 



This species, while very close to hrassicae, can be separated from 

 that species by the characters noted in the key. 



Besides the types, there is in the National Collection material from 

 the following localities: Riley County, Kansas; Long Island, New 

 York; Champaign, Illinois; Douglas County, Kansas; Nashville, 

 Tennessee (C. C. Hill) ; and a specimen, without locality data, reared 

 from Cirphis unipuncta. Doctor Brues's collection has a single speci- 

 men from Chicago, Illinois ; and in the Cornell University collection 

 there are two specimens, from Caroline-Hartford, and Axton, New 

 York. 



19. MICROPLITIS BRASSICAE, new species. 



Very closely resembles melianae; but it can be readily distinguished 

 from that species by the longer stigma, which is also more contrast- 

 ingly pale on the basal third ; the posterior tibiae are slightly dusky 

 at extreme base in hrassicae., not so in rnelianae; also the head is more 

 coarsely punctate and opaque in the latter. 



Female.— luQngih. 2.7 mm. Face, vertex and temples very minutely 

 punctate, somewhat shining; antennae as long as the body; mesoscu- 

 tum and scutellum shallowly punctate and opaque, the latter de- 

 cidedly convex; mesopleurae finely punctate and dull, with rather 

 long, thick pubescence anteriorly and below the longitudinal crenu- 

 late furrow, impunctate and highly polished above; propodeum 

 rugose, with a median longitudinal carina ; stigma large, distinctly 

 longer than the metacarpus, and decidedly more than twice as long 

 as its greatest breadth; radius strongly directed outward, hardly
