Besides new species Walsh describes of the Inqidlince Sgnophrus Iceci-

Bassett remarks that the J of his Cgnij)s q. singidaris {=C. q. nubilipennis, 
Harr.) and of C. q. scitula, n. sp., have 16 joints in the antennae, and that the 
$ of C. q. formosa,s^. n., and C. q. ventricosa, sp. n.,have 15 joints. Proc. 
Ent. Soc. Philad. vol. iii. p. 680. 
The same author describes the following known species of Cgnips : C. q. 
batatas (Fitch), and C. q. tuber (Fitch). 
Some remarks on the habits of Cgnips aptera, and on the relations of the 
sexes in the genus Cgnips, by Saunders, Smith, and Westwood, are published 
in Proc. Ent. Soc. Lond. 1864, pp. 47, 48. 
Lucas describes an. agglomeration of galls of Cgnips (Apophgllus) aptera.

New species : — 
Tribalia (g.n.) batatonim,'^ a\&\\, Proc. Ent. Soc. Philad. vol. ii. p. 471, from 
Illinois. 
Cgnips. Of this genus Walsh describes as new species : Cgnips quercus 
Jlocci 9 ; 1- c. p. 482 ; C. q. forticoi'nis $ , 1. c. p. 490 ', and C. q. podagrce $ 
(=?C. q. punctata, Bassett?), 1. c. p. 492. 
Bassett (Proc. Ent. Soc. Philad. vol. iii.) gives full descriptions of the 
following new North American species of Cgnips and of the galls from which 
they are produced ; Cgnips q. formosa, I. c. p. 679, on Quercus rubra j C. q. 
ventricosa, 1. c. p. 681, on Q. ilicifolia *, C. q. ilicifoliee, 1. c. p.-682, on the 
same ; C. q. majalis, 1. c. p. 683, on Q. alba-, C. q. scitula,. \. c. p. 683, on Q. 
tinctoria ; C. q. similis, 1. c. p. 686, on Q. ilicifolia : C. q. hirta, 1. c. p. 688, on 
Q. montana. Bassett also describes two kinds of galls, the insects producing 
which are still unknown — one on the leaf-buds of Q. chinquapin, the other 
on the leaves of Q. rubra. For the Gall-fly of the former he proposes the 
name of Cgnips q. frondosa, and for that of the latter C. q. decidua.
