ART. IS. NOTES ON CYNIPID WASPS WELD. 9 



The writer has seen these galls in Virginia, New York, and Illinois 

 also and museum specimens from Vermont and New Hampshire, in- 

 dicating a widespread distribution of the species. 



There is a precisely similar gall in Q. prinus, which will no doubt 

 prove to be due to this species.

hubbardi Ashmead. 

 Parateras hubhardi Ashmead was described from two specimens 

 from Detroit, " nothing known regarding habits." One of these is 

 in the United States National Museimi. Its hind tarsi are shorter 

 (not longer) than their tibiae in the proportion of 50 : 59, and the 

 tarsal claws are simple (not toothed). In both respects it does not 

 differ from the type of vacehii'. In vaeinii the third joint of the 

 antenna was said to be " as long or nearly as long as joints 4 and 5 

 united," but a balsam mount shows the length of the first seven seg- 

 ments to be as 13 : 8 : 19 : 13 : 11 : 10 : 9, so that the third is distinctly 

 shorter than 4 plus 5, and in this respect it does not differ from 

 huhhardi. Both have the same type of scutellum, the second tergite 

 occupying slightly over six-tenths of abdomen, the same type of ven- 

 tral spine, the head not broadened behind the eyes, malar space less 

 than half eye, the parapsidal grooves strongly converging behind, and 

 both are entirely wingless. Therefore hubhardi seems to be con- 

 generic with vaccinii and Parateras a synonym of Zopheroteras. 



The species vacinii was described from a "huckleberry-like" gall 

 in clusters on midrib of post oak, dropping to ground in fall, and the 

 type galls answer this description. They are evidently galls of a 

 winged species which Beutenmueller has described as Andricus im- 

 positus. In picking up galls Ashmead evidently picked up a few of 

 a different sort, from which he rearer two wingless flies, which he 

 called vaccinii, and associated them with the wrong gall. The gall 

 of this Zopheroteras is then still undescribed. 



The gall of hubbardi is still unknown. The writer has seen one 

 fly which he has determined as that species by comparison with the 

 type from Bladensburg, Maryland, captured April 8. 1915, by L. O. 

 Jackson, and another from Bellmore. Long Island, collected by 

 G. P. Englehardt. 



Dalla Torre and Kieffer are apparently in error in making Zoph- 

 eroteras a synonym of Trigonaspis. It does not seem at all related to 

 the European wingless form, Trigonaspis megaptera (Panzer).
