NO. 2197. NEW PARASITIC HYMENOPTERA—OAHAN. 209 



pale throughout, and the head and thorax less strongly sculptured. 

 Readily distinguished from secundiis by the absence of any stigmal 

 cloud in the forewing, the projecting scutellum, and the more nearly 

 perpendicular propodeum. 



Head and thorax closely punctate, somewhat shining, the punctures 

 rather shallow and indefinite on the lateral lobes of the mesoscutum, 

 the scutellum and axilae; antennae with all joints of the funicle and 

 club transverse though not strongly so; pedicel longer than thick; 

 propodeum faintly sculptured; postmarginal vein of the forewing 

 about twice the length of the stigmal; abdomen finely lineolated. 

 Head and thorax green, abdomen bronzy, the tergites tinged with 

 green basally ; all coxae and femora concolorous with the thorax, the 

 tibiae and tarsi pale testaceous; wings hyaline, the veins pale; an- 

 tennal flagellum and pedicel brownish, the scape testaceous. Male 

 unknown. 



Type-locality. — Tempe, Arizona. 



Type.— Cat. No. 20387, U.S.N.M. 



Six females reared by R. N. Wilson and recorded in the Bureau of 

 Entomology under Webster No. 7270E. The types were reared from 

 seed infested with Bruchophagus funebris and it is probably para- 

 sitic on that host. 



Family PTEROMALIDAE 



Subfamily Pteromalinae. 



SYSTELLOGASTER, new genus. 



Runs to Coelophisthia in Kourdumoff's key to the Pteromalidae, 

 but may be separated from that genus by the fact that the face is not 

 abruptly truncate below the antennae, but only slightly receding, the 

 antennae being inserted considerably above the clypeus though dis- 

 tinctly below the middle of the face; the wings are distinctly though 

 not strongly ciliated on the disk and the first antennal ring joint is 

 transverse. Differs from Dihrachys and Coelopisthoidea principally 

 in the abdomen being short and subtruncate at apex instead of 

 conic ovate, and the propodeum incised at the posterior lateral angles 

 for the reception of the hind coxae, giving the appearance of a short 

 broad neck; the propodeal spiracles large. 



Type of the genus. — Systellog aster ovivora, new species. 



SYSTELLOGASTER OVIVORA, new species. 



Female. — Length 1.8 mm. Antennal pedicel more than twice as 

 long as the first funicle joint, first ring joint transverse, the second 

 nearly as long as wide, funicle six-jointed, the joints subequal and 

 about as long as wide, or slightly transverse, club not broader than
