Is^OTES ON GYNIPID WASPS WELD.

Species (a) is a rare find congeneric with a species on which Ashmead founded the genus 

 Euceroptres, a guest g^enus distinct in the writer's opinion from Ceroptres. It was not 

 recognized by Doctor Kinsey. Bassett's description of cicatricula does not apply to this 

 species. 



Species (6) is Bassett's cicatrioila, to which his description does apply. It is a true gall 

 maker, with the pronotum " narrow " in middle. It vastly outnumbers all the others. 



Species (c) ia determined by the writer as Callirhytis tumiflca (Osten Sacken) from an 

 accidentally included and unnoticed gall somewhat similar in .shape on a rt-d oak and 

 yielding flies at about the same time. Bas.sett's description does not apply to this. 

 This is presumably the "single (undescribed) female of the Bassett types" in the 

 .\merican Museum, and it was in the row the first specimen of which was labeled 

 concoJorans. 



Species (rf) is also a Callirhytis, but unknown to the writer, and he will not describe it. 

 Bassett's description does not apply to this. It must have issued from another un- 

 noticed gall. 



Doctor Kinsey has transferred Bassett's cicatricula^ which is a true 

 gall maker, to the genus Ceroptres^ where it does not belong. Then 

 he has taken a large series of cicatricula from the Thompson collec- 

 tion, and under the mistaken impression that it matched the single 

 female (c) in the American Museum has redescribed the species under 

 the name of concoloraiis, which becomes a synonym of circatrncula. 

 All type material of concoloram seen by writer consists of ma- 

 terial from the Thompson collection only and agrees with types of 

 cicatricula. The figures of the galls of concolorans on alha seem to 

 be like the types of cicatricula. The conclusion is that we have here 

 just one species which ranges throughout the eastern half of the 

 United States and forms galls on several white oaks. 



The writer has reared flies from galls on Quercus michauxii from 

 Ocala, Florida, an oak not previously recorded as a host of this 

 species, 



ANDRICUS VERNUS (Bassett). 



Amphibolips vcrna Bassett, Trans. Amer. Ent. Soc, vol. 26, 1900, p. 321. 

 This species was described from a single specimen taken April 9 

 ovipositing in bud of Q. ilicifolia. It is an Andricus. 



CALLIRHYTIS BADIA (Bassett).

32, figs. 16, 17. 



While studying the Bassett collection at Philadelphia in May, 1921, 



the writer suspected that the type of Amphiholijys hadius Bassett 



described from an unknown gall was the same as Callirhytis corallosa
