Kinsey: Gall Wasp Genus Cynips

shining, the hypopygial spine is short, not fine but not broadened as in 
true Cynips, without the terminal tuft of hairs typical of Cynips. 
Niger Fourcroy, 1785, Ent. Paris: 392. Based on Diplolepis No. 4 
Geoffroy, 1762, Hist. Ins. 1 : 311. Diplolepis in orig. publ. and still 
maintained by Dalla Torre and Kieffer, 1910. Original description in- 
sufficient for recognizing any cynipid. Gall not described. 
Notha Osten Sacken, 1870, Trans. Amer. Ent. Soc. 3: 55. Cynips in 
orig. publ. Andricus, Callirhytis, Dryophanta of later authors. I have 
compared the types with the types of palustris at the Museum of Com- 
parative Zoology. The two insects belong to the same group and are 
ruled out of true Cynips on the same basis. See palustris in this list. 
Occultata Weld, 1926, Proc. U.S. Nat. Mus. 68 (10): 28. Diplolepis 
in orig. publ. I have studied the holotype and numerous paratypes. 
The agamic insect is rather small, the mesonotum conspicuously cori- 
aceous and almost naked, the scutellar foveae distinctly separated, the 
hypopygial spine slender, needle-like, and without a terminal tuft of 
hairs, and the wings perfectly clear with fine veins and a very faint 
base to the cubitus. The agamic gall is a seed-like cell in a bud. None 
of these are Cynips characters. 
Operta Weld, 1926, Proc. U.S. Nat. Mus. 68 (10): 19. Diplolepis 
in orig. publ. I have studied the holotype and most of the paratypes. 
The agamic insect is rather small, the mesonotum conspicuously cori- 
aceous and almost naked, the scutellar foveae distinctly separated, the 
hypopygial spine slender, needle-like, and without a terminal tuft of 
hairs, and the wings perfectly clear with fine veins and a very faint 
base to the cubitus. The agamic gall is a seed-like cell in a bud. None 
of these are Cynips characters. 
Palustris Osten Sacken, 1861, Proc. Ent. Soc. Phila. 1:63. Cynips 
(Trigonaspis?) in orig. publ. Cynips, Andricus, Callirhytis, and Dryo- 
phanta of later authors. I have insects which I compared with the holo- 
types some years ago. This bisexual insect is superficially similar to 
bisexual Cynips, but the hypopygial spine is short, not slender but no- 
where broadened as in Cynips, and without a distinct terminal tuft of 
hairs. The galls are inseparable leaf galls or flower galls, spherical, 
hollow, with the larval cell rolling about loose in the otherwise empty 
gall. They occur on species of black oaks. There are several other 
species or varieties of this group that are commonly but wrongly as- 
signed to our present genus. They are all ruled out of Cynips by the 
same characters. 
Papula Bassett, 1881, Canad. Ent. 13: 107. Cynips in orig. publ. 
Andricus, Dryophanta, and Diplolepis of later authors. Weld (1922) 
considers this a Callirhytis. I have seen the holotype, in the Philadelphia 
Academy, and several paratypes. Differing from Cynips in every es- 
sential character. The wing veins are faint, the hypopygial spine is 
short, slender, pointed, without a terminal tuft of hairs, and the gall 
occurs on black oaks!
