THE FAMILY EUCHARIDAE — GAHAN 435 



or elevation on the propodeum laterad of each spiracle place the 

 species in the genus StUhula instead of Schizaspidia. In fact, I am 

 able to distinguish these specimens from S. cyniformis (Rossi) * 

 (type of the genus), as represented by European specimens identified 

 by F. Ruschka, only by the fact that the face of the Japanese form 

 is more distinctly transversely striated and the coarse punctures con- 

 stituting the sculpture of scutellum are somewhat smaller and cor- 

 respondingly more numerous than in the European form. These 

 differences are not very pronounced, and it seems quite possible that 

 S. tenuicornis is merely a geographical race of S. cyniformis. 



STILBULA POLYRACHICIDA (Wheeler and Wheeler), new combination 



Schizaspidia polijracliicida Wheeleb and Wheexee, Psyche, vol. 31, p. 49, 1924. 



This species, which is represented in the National Museum by one 

 female specimen (the type), apparently belongs in StUhula. The 

 flagellar joints are cylindrical, not serrate, the scutellar process is 

 short, the spiracular furrows on propodeum are broad and deep, and 

 there is a more or less distinct elevation laterad of the spiracle. 



The species is readily distinguished by a broad, deep, rounded 

 pit at the base of the scutellum between the axillae (not on the 

 metanotum as stated in the original description). 



STILBULA FLORIDANA (Ashmead), new combination 



Lophyroccra floridana Ashmead, Ent. Amer., vol. 3, p. 187, 1SS8. 



This species is excluded from Lopkyrocera by the fact that the pro- 

 podeum is without toothlike processes. The only female representa- 

 tive of this species in the U. S. National Museum collection lacks the 

 head, but the species is so nearly identical with septejitrlonalis 

 (Brues) that it seems safe to assume that the antennae, like those 

 of septentrionalis, are not serrate, a character that would also throw 

 it out of Lopkyrocera. The antennae of the male have the flagellar 

 joints long and cylindrical, and the other essential generic characters 

 are those of StiTbvIa. 



STILBULA SEPTENTRIONALIS (Brnes), new combination 



Schizaspidia septentrionalis Brues, Bull. Wisconsin Nat. Hist. See, vol. 5, p. 104, 

 1907. 

 The type of this species, formerly in the Brooklyn Museum but 

 now in the U. S. National Museum, is apparently congeneric with the 



<This species name was emended by Kirby (Journ. Linn. Soc. London, Zool., vol. 12 

 p. 31, 188G) to cynipiformis, and the emendation has been accepted by some subsequent 

 authors. The emendation, however, seems equally as incorrectly formed as the origina 

 spelling, and since any change of the name was unnecessary, I prefer to use the original 

 spelling.
