SPECIES OF UNCERTAIN POSITION. 

 PLATYGASTER ACICULATA Ashmead. 



Platygaster aciculatus Ashmead, Bull. 45, U. S. Nat. Mus., 1893, p. 32. 

 The original description is as follows: 



Male. — Length 1.4 ram. Black, shining; vertex, occiput and cheeks finely sha- 

 greened; face transversely aciculated; sides of prothorax, mesonotuni, mesopleura 

 beneath the wing? and the metapleura all distinctly longitudinally aciculated; the 

 parapsides, scutellum, and the lower portion of mesopleura smooth, polished. Anten- 

 nae 10-jointed, rufo-piceous; the flagellum subclaA'ate; pedicel longer and stouter than 

 the first and second funiclar joints together, the latter scarcely longer than thick, 

 the following joints to the last transverse, the last short, conic. Parapsidal furrows 

 ■deep, distinct. Scutellum elevated, cushion-shaped. Legs rufo-piceous, tips of 

 anterior femora and their tibiae and the articulations of the middle legs yellowish. 

 Wings clear hyaline, entirely devoid of pubescence. Abdomen oval, smooth, pol- 

 ished, the petiole not longer than thick, striated and pubescent, the second segment 

 with some striae at base. 



Type locality. — Pennsylvania. 



Type. — In Berlin Museum. 



Described from a single speciinen labeled "Penn., Zimmerman." 



This species would probably fall under the group having the 

 scutellum shagreened and the notauli complete, although Ashmead 

 says nothing about the sculpture of the scutellum in the description 

 quoted above.
