55. Grail on Q. prinoides, called O. q.frondosa Bassett, Proc. etc. 

 ITT. p. 688. 



56. Spindle-shaped galls, inserted like pins on the leaves of Q. pri- 

 noides, described by Dr. Fitch (Rep. IT, No. 320). He bred from it 

 an insect which he calls Figites chinquapin. The description of the 

 gall answers that of C. fusiformis very well ; that the insect obtained 

 from it by Dr. Fitch is the real author of tbe gall is possible, but un- 

 certain. Likewise it does not appear why Dr. Fitch calls this gall-fly 

 a Figites. 



57. Gall on Q. alba, described by Dr. Fitch (Rep. II. No. 319) as 

 that of C. q. pisum, which, however, is a guest-fly. I mention this 

 gall-fly at this place, as I am not quite certain whether G. pezomachoides 

 O. S. has been bred from a gall on Q. alba. (Compare above, No. 12. ) 



58. Grail on Q. alba, described by Mr. Walsh as G. q. erinacei, 

 (Proc. etc. II, p. 483) the gall-fly being unknown. About the iden- 

 tity of this gall with the preceding compare above. No. 12. 



N. B. — The following galls on the live oak (Q. virens). described 

 by me in my former papers, have been altogether omitted in the Sy- 

 noptical table, as well as in the Remarks, both of which were especially 

 intended for the fauna of the Middle and Northern States: — 



I. On leaves. 



1. Small globular gall, Proc. etc. I, p. 57. 



2. Woolly gall, Proc. etc. I, p. 259. 



II. On branches. 



3. Clusters of galls not unlike the galls of C. forticornis Walsh 



in appearance, Proc. etc. I, p. 258. 



4. Woody swelling of the limb, Proc. etc. I, p. 258. 



The gall-flies of all these galls are unknown. 



Genus KHODITES. 

 (Galls on the genus Rosa.) 

 The six N. A. species of this group are sufficiently characterized in 

 the Proc. etc. IT, p. 45 and the following. 



Genus DIASTROPHUS. 



(Galls on the genera Rubus and Potcntilla.) 



To the two species described by me, (Proc. etc. II, pp. 36 and 39) 



and occurring on Rubus, Mr. Bassett had added a third, bred from a 



gall on Potentilla (Proc. etc. Ill, p. 690.) It is somewhat like my D. 



nebulosus, but certainly distinct.
