Genus CALLIRHYTIS Foerster 

 CALLIRHYTIS CORRUGIS (Bassett) 



When I previously reported (Proc. Ent. Soc. Washington, vol. 33, 

 p. 225, 1931) that this species had been taken in numbers ovipositing 

 in buds of Quercus maxima^ Q. velutina, and Q. palustris at various 

 dates in April at East Falls Church, Va., the gall from which they had 

 emerged was not known. It can now be reported that the species has 

 now been reared from "stone" galls in acorns of all the above oaks — 

 galls not distinguishable from those of Callirhytis fructuosa Weld. 

 Acorns of red oak were collected in Loudoun County, Va., on Septem- 

 ber 22, 1940, and from them fructuosa emerged April 19, 1942, and 

 corrugis May 4, 1943, and April 20, 1947. Acorns of pin oak were col- 

 lected at East Falls Church, Va., on October 20, 1940. C. corrugis 

 (Bassett) emerged April 12, 18, 26, 1942; April 18, 1944; April 14, 

 1945, and April 6, 1946. Two species thus sometimes make similar 

 galls in acorns of the same host oak. The alternating gall produced 

 by these adults which oviposit in buds has not yet been discovered. 



CALLIRHYTIS MODESTA (Osten Sacken) 



In the box of Bassett cynipid types in the American Entomological 

 Society the type of Cynips pajmla Bassett, a synonym of modesta^ is a 

 female of Ceroptres sp., a guest fly. A pinned specimen in another 

 case marked "cotype" is the maker of the gall and has now been made 

 the type. This is in spite of the fact that the original description of 

 papula was drawn from specimens of two genera and combined the 

 head and thorax of the guest with the abdomen and wing of the 

 maker. 



CALLIRHYTIS CISTELLA, new species 



Female. — Head and thorax amber, dull; abdomen red, shining; 

 propodeum and tips of antennae infuscated. Head from above trans- 

 verse, narrower than thorax, cheeks not distinctly broadened behind 

 eyes; from in front broader than high, malar space .4 eye, slightly 

 striate; antennae filiform, 13-segmented. Mesoscutum finely and 

 uniformly rugose, appressed pubescence short, parapsidal grooves ob- 

 solete anteriorly, median short. Disk of scutellum slightly coarser 

 posteriorly, not humped back of the narrow septum between two 

 smooth shining pits. Mesopleuron striate on lower half. Wing 

 hyaline, surface dotted, nonciliate, veins brown, not clouded, abscissa 

 I of radius arcuate, areolet wanting. Claws simple. Abdomen as 

 high as long, gibbous below petiole, only two tergites on dorsal mar- 

 gin ; ventral spine 7 times as long as broad, longer than hind meta-
