This appears to be nearest related to Ph. foi'eola n. sp. and 

 Ph. intermedia n. sp., though as no opportunity has offered to 

 further &iM^y foveatiim at Washington, Shimer' s original descrip- 

 tion is reproduced : 



"On the same leaves [of Carya amard\ containing the small 

 galls, Nos. 7 \Ph. minimum Shimer] and 8 [/%. c. -semen Walsh] , 

 I observed a number of larger ones with a dimpled depression 

 above (which may be caused by the collapse of the thin paper- 

 like centre), an opening beneath by a rounded, downy orifice, and 

 having a diameter of .06-. 33 inch [1.5"""] and a vertical depth of 

 . 12-. 16 inch [3-4™™] ; all contained the female and her eggs, and 

 some larvae. 



"Winged imago. — Abdomen and prothorax pale orange, with a dark 

 band or ring around the mesothorax; wings carried flat on the back in 

 repose, hyaline, veins small, stigma very faint, smoky; antennas 3-jointed, 

 the last joint long, subcylindrical and on a very long pedicle; abdomen 

 quite pointed. Length to tip of wings .06 [1.5'"™]; of antennae .005 inch 



[O.imni.]. 



" Mother insect. — Pale yellow, palest posteriorly. Length .04 [i'"'"]; 

 width .2 inch [0.05™"']. 



' ' On June 20th the winged imagos were verj- plenty, but no 

 eggs could be found." 



[As printed in Trans, of the Am. Ent. Soc, Xo\. II., p. 393. the name of this species 

 reads Dactylosphixra forcatuvi and not forcatuvi, as used by Riley, Thomas, and others. 

 The word as used in the Transactions is evidently a misprint which originally read 

 foveaiiim, with reference to the dimpled depressions on the upper side of the leaf. The 

 corrected spelling is used in the index to the volume. I deem it, therefore, proper to 

 correct those errors.]— Theo. P.
