ORASEMA SIMULATRIX, new species 



Female. — Length 3.5 mm. Apparently agrees in every respect 

 with the description of aureoviridis except in the following partic- 

 ulars: Antemiae very slightly less distinctly clavate; propodeum 

 more evenly alveolately punctured, less distinctly flattened medially, 

 with the pits or foveae on each side of the median carina much 

 smaller; costal cell of forewing with approximately 20 weak discal 

 cilia; color of head and thorax dull dark green, without conspicuous 

 brassy tints; propodeum dull blackish with a distinct purplish tinge; 

 pleura in part, apex of scutellum and the thoracic sutures tinged with 

 purplish; gaster purplish black with an aeneous tinge, its first seg- 

 ment (second tergite) mostly metallic green; coxae green; femora, 

 tibiae, and tarsi yellowish testaceous as are also the mandibles, scape, 

 pedicel, and tegulae; flagellum blackish brown; wings hyaline. 



Type locality. — Oracle, Ariz. 



rype.— U.S.N.M. No. 53556. 



Described from 1 female specimen collected by Hubbard and 

 Schwarz at Oracle, Ariz., July 14, 1898. 



ORASEMA NEOMEXICANA, new species 



Female. — Length 2.6 mm. Differs from the description of robert- 

 soni, besides in the smaller size, by having the abdominal petiole very 

 little, if any, longer than broad, the postocellar line obviously longer 

 than the ocellocular line, the lateral ocellus about twice its own diam- 

 eter from the eye margin, none of the flagellar joints except the first 

 longer than broad, the supraclypeal area polished medially and sepa- 

 rated from clypeus by a shallow but distinct groove connecting the 

 clypeal foveae, the upper half of mesepimeron smooth, the scutellum 

 a little less convex dorsally and with its lateral carinae not quite so 

 far below the dorsum. The color is as in robertsoni except that the 

 mesoscutum and scutellum are more strongly tinged with coppery 

 and the antennal scape and the femora are not washed with metallic. 



Male. — Unknown. 



Type locality. — San Augustine Kanch, at eastern base of Organ 

 Mountains, N. Mex. 



Type.—V.S.^.M. No. 53557. 



Described from 3 females collected by T. D. A. Cockerell and bear- 

 ing his numbers 2163, 2265, and 2268. Also 1 female taken by Cock- 

 erell at Albuquerque, N. Mex., on Guiterrezia. A female collected by 

 W. M. Mann at Las Parras, Baja California, in October 1923 seems 

 to agree with the types except that the abdominal petiole is fully one 

 and one-half times as long as broad.
