NO. 2261. NEW REARED PARASITIC HYMENOPTERA—OAHAN. 127 



deep; ocellocular line a little longer than the lateral ocellar line, 

 slightly more than half as long as the postocellar line; propodeum 

 much more hnely sculptured than the scutellum; forewing more 

 sparsely ciliated than usual, the basal portion to the junction of the 

 submarginal and the marginal veins entirely bare, the middle of 

 the wing behind the marginal vein with distinct sparse cilia, the api- 

 cal portion beyond the apex of the stigmal vein more closely ciliated. 

 Abdomen smooth and polighed except the fifth and sixth tergites 

 which are weakly lineolated. 



Male. — Agrees with the female except that it is slightly smaller, 

 and the abdomen is shorter, more elliptical with the fifth and sixth 

 tergites less obviously lineolate-reticulate. 



Type-locality. — Tempe, Arizona. 



Type.—CdX. No. 21622, U.S.N.M. 



Host. — Agromyza gibsoni Malloch. 



Eight females and seven males reared from larvae by F. H. Gates 

 and recorded in the Bureau of Entomology under Webster No. 12239. 



HABROCYTUS SIMILLIMUS. new species. 



Female. — Length 2.4 mm. Very similar to small specimens of H. 

 Janguriae Ashmead, but apparently differs as follows : The body ap- 

 pears somewhat more slender ; the clypeus is not as distinctly defined, 

 the striations ixot being terminated at a depressed line or very fine 

 groove which in languriae separates the base at least of the clypeus 

 from the face; the spiracular sulci of the propodeum are shallow, 

 though complete ; the apex of the scutellum does not show a puncta- 

 tion different from that of the remainder; the body color appears to 

 be more of a blue green, lacking the bronzy tinge of languriae^ and 

 all of the femora are blackish, sometimes slightly metallic. 



Male. — Length 2 mm. Anterior and median femora pale ; the pos- 

 terior femora fuscous except apically; abdomen with a testaceous 

 patch embracing the apex oi first and most of the second tergites; 

 other characters, except the usual sexual ones, as in the female. 



Type-locality. — Tempe, Arizona. 



Type.—Q^ii. No. 21623, U.S.N.M. 



Host. — AgroTTiyza gibsoni Malloch. 



Seven females and three males reared by Mr. F. H. Gates from the 

 pupa of the above-named host and recorded in the Bureau of Ento- 

 mology under Webster No. 12239. Antennae and mandibles of a par- 

 atype on a slide. 



In view of the great similarity between this supposed new species 

 and languriae and the further fact that I have received specimens of 

 the latter species from Tempe, Arizona, reared by Mr. Gates from 

 Languria mozardi^ which, like Agromyza gibsoni, is a stem borer in
