ABT. 15«. EEVISIO]Sr OF SUBFAMILY PLATYGASTERINAE FOUTS. 73 



Male. — Length 1.5 mm. Pedicel twice as long as wide, as wide as 

 joints three and four; three slightly longer than wide, indistinctly more 

 than half as long as the pedicel; four as long as the pedicel, narrowed 

 basally and apically; following joints about one and one-third times 

 as long as wide; ten twice as long as Avide, longer than joint two, 

 pointed apically; abdomen broadly elliptical, four-sevenths times as 

 wide as long, as long as the head and thorax united, as wide as the 

 thorax; segments three to seven united half as long as the second; 

 wings hyaline, reaching the length of the last five segments past the 

 apex of the abdomen. Coloration as in female. 

 Type locality. —San Francisco, California. 



Type.— Cat. No. 2271, U.S.N.M. Type female and allotype male 

 selected. 



Redescribed from the type material, two females and two males. 

 The female types have no abdomens, the latter having been lost before 

 I saw the specimens. 



In Ashmead's type series are two other specimens, a male and a 

 female, which represent another species. They are referable to the 

 other group of the genus in which the head is thick anterior-poste- 

 riority and the sculpture strong. Ashmead described the male of this 

 later species as lupinicola since he mentions the notauli as being com- 

 plete. The species lupinicola must, however, be restricted to the 

 female which was described first and has therefore been made the 

 electotype. 



All of the specimens mentioned above were reared November, 1885, 

 from a Cecidom3dd gall on Lupin us athorea, collected Mr. Albert 

 Koebele.
