Gall-fly.— '^ . Length .20 inch. Reddish brown, coarsely rugosely punctate 

 and clothed with long gray pubescence, pubescence is longer and thicker on head 

 back of eyes, episternum, pleura and first abdominal segment. Head small, 

 darker than body, very finely rugoso-punctate on vertex back of eyes; a series oF 

 coarse grooves converging towards and around the mouth ; antennae 14-jointed, 

 third joint longer than first and second combined ; scutellum elevated, bifoveolate ; 

 legs finely rugoso-punctate, brown and very pubescent, femora darker; abdomen 

 dark brown, smooth and shining, first segment more densely pubescent on upper 

 surface, and entended in short pubescence to tip, beneath smooth ; wings hyaline, 

 radial area open, the radial vein, however, almost touches the outer edge, areolet 

 three-fourths closed, veins brownish. 



Described from three S specimens taken from old galls. 



It is exceptional to find the same gall growing on dififerent species of 

 oak, especially widely different species, but the above species seems to live 

 on all. I have found it on Quercus virens, Q. Catesbxi and Q. cinerea. 



Another gall on the Live Oak, found on the under side of the leaves, 

 growing frequently along side Cynips q. lanigera has been known to me 

 for some years, but I have been unsuccessful in breeding the gall maker 

 until this spring. 



Cynips q. luinutissiuia n. sp. 



Galls. — Small, minute galls, a little larger than a pin's head, on the 

 under side of the leaves of Quercus virens and covered with coarse, 

 brown, mossy pubescence ; diameter ; diameter of gall with pubescent 

 growth .05-. 10 inch. Sometimes there are several galls together. 



Oall-fly. — 9 . Length .04-.05 inch. Black, smooth and shining, but showing 

 faint delicate aciculations under a high power lens. Antennae 14-jointed, yellow- 

 ish brown, third joint longest; legs yellowish brown, femora infuscated along 

 upper surface ; wings hyaline, veins yellowish, radial area open, the tip of sub- 

 costal just touches outer edge, but is not thickened along the edge, radial vein 

 reaches the margin ; areolet obliterated ; abdomen black shining, triangular in 

 outline with prominent ovipositor sheaths. 



Described from four 9 bred specimens. 



GrALLS ON THE WiLLOW Oak, — Quercus laurifoUae. 



A round or spherical gall drops from the large trees of this oak in 

 August, and I have been unable to find out whether they grow on the 

 twigs or on the leaves. 



Although the galls are common, the gall-fly is yet hard to raise, and 

 the description is made from several discovered in boxes of the galls put 

 away in 1881. 



Cynips q. fuliginosa n. sp. 



Galls. — Brown, mottled, globular galls, .35 inch in diameter, hard, 

 of a fine corky texture with a central kernel.
