ART. 18. NOTES ON CYNIPID WASPS WELD. 27 



from greenhouse at Oregon, Missouri, over 30 years ago. The label 

 on the type galls plainly says Stephanomeria^ which is a composite 

 close to Lygodesmia distinguished by its pink flowers and plumose 

 pappus and perhaps not separable from it on September 17, when 

 the galls were collected and from the material sent in. Both have 

 filiform naked branches, milky juice, and alternate leaves. Only one 

 species of Stephanomeria would be at all likely to occur in that 

 locality, and the genus is entirely omitted in the seventh edition of 

 Gray, which does include that area, so there is strong probability 

 that the host was misdetermined and that the stephanotidis galls 

 were on Lygodesmia. At any rate, if it does attack the closely related 

 genus Sfephaoiomerla, no one has found it on it since. As stephano- 

 tidis is the genotype of the genus Aselepiadiphila Ashmead, Anti- 

 strophus Walsh and Asclepiadiph'la Ashmead are isogenotypic 

 through synonymy. 



Dalla Torre and Kieffer have erroneously recognized the species 

 stephanotidis and made AsdepiadiphUa a synonym of Aijlax instead 

 of Antisfrophits.
