CYNIPIDyE. 
359 
Sula Islands, possessing membranaceous dilatations on the neck, basal joint 
of ontennaB, femora, and tibifo. 
For an account of a largo brood of Cynips ramuli, cf. Pr. E. Soc. 1870, 
p. XXX. 
Muller (Pr. E. Soc. 1870, p. xxxiv) refers to the economy of Cynips 
rcnum and C. ayama. 
Walsh and Riley (Anier. Ent. i.), in a general article on American gall- 
producing insects and their parasites, describe the economy and figure the 
galls of C. qncrcm sponyijica (O.-S.), p. 103, fig. 78 j C. quercus inanis (O.-S.), 
p. 104, fig. 79; C. querciis primus (gall only described by Walsh, Proc. Ent. 
Soc. IMiil. iii.), sp. n. They also name qncrcm mamma (p. lOJ, note) a gall 
resembling Q. ylobidm, Fitch, and referred to it by Walsh, /. c., but now dis- 
covered to bo produced by a diflerent sp. from tlie insect causing that gall. 
After Walsh’s death, Riley continues (/. c. ii.) the articles on American galls, 
but attributes the Hymenopterous portion exclusively to Walsh, lie de- 
scribes the economy and figures the gall of C. q. seminator, Harris, p. 71, 
tig. 45 ; describes and figures (with doubt) the gall Qiicrcm frondosa, Bas- 
sett, p. 72, fig. 40 ; and a now gall, Lyyodcsmicc pisum^ p. 73, fig. 47, on the 
insect producing which a now genus is founded, p. 74. 
MuI'Eer (Ent. INI. M. vii. p. 38) records some observations on the dimor- 
phism of American Cynipidcc. 
An odour, similar to that of ants or bees, exhaled by an American sub- 
apterous sp. of Cynipidcs, is mentioned by Muller, Pr. E. Soc. 1870, p. xvi. 
Miiller also notes odours exhaled by Cynipidcc in Zool. s. s. p. 2027. 
Andricus curvatoi'y Iltg. Muller {1. c. p. 39) describes the gall of this 
species from British examples ; and (p. 167) also describes the economy of 
A, injlator, Htg., from British examples. 
Mu ller (Zool. s. s. p. 2303) records an instance of unusual oviposition by 
Jlhodites ros <2 (L.). 
Bedeguars caused in N. America by Rhodites roscc (L.) are described and 
figured by Riley, Amer. Ent. & Bot. ii. p, 213, f. 130. 
Prickly galls on wild rose, caused by Rhodites hicolor (Harr.), are described 
and figured in Amer. Ent. & Bot. ii. p. 309, f. 192. 
Galls on raspberry-roots caused by Rhodites radicum, O.-S,, are described 
and figured (f. 110) by Riley, 1. c. p. 181. 
Galls on blackberry- canes caused by Diastrophus nebulosm, O.-S., are de- 
scribed and figured (f. 103) by Riley in Amer. Ent. ii. p. 169. 
Antistroqihus, g. n., Walsh, Am. Ent. ii. p. 74. Third joint of ant. much 
shorter than 4th ; both, transverse veins of front wingS as slender as other 
veins, almost colourless, and with no cloudy margin ; radial area elongate, 
areolet obsolete. Sp. A. lyyodesmiee pisum, sp. n., Walsh, ibid., gall figured 
at p. 73, Nebraska, U. S. A., infests Lyyodesmia {Compositce) ; ? also a Ria- 
strophus from Ccntaurea, reared by Giraud (Verb. z.-b. Wien, 1869).

Cynips corruptriv, v. Schlecht. 1. c. p. 339, Freiberg (oak) ; C. albopunctata, 
V. Schl. 1 . c. p, 376, Halle (Q. pedunculatd)), C. qtiercus mamma^ Walsh & Ri- 
ley, 1. c. p. 102, note, N. America, on burr-oak; C. quereus prumis, W. & R.
