NORTH AMKRICAX IIYMKXOPTKKA. ^ 137 



Gall-fly.— 9 . Length .OS inch. Head and thorax dull hrown ; al)donien hlack, 

 shining (one specimen distinctly brownish at base, antemue 14-jointed, rather 

 long, tip from eighth Joint infuscated; parapsidal grooves very indistinct; scii- 

 tellum ending in a small elevated horn ; all tibise dark-brown along outer edges. 

 Entirely apterous without even wing .scales. 



Described from two speciiuens bred in February, 1886. 



This gall is common ; begins developing in August, but does not 

 reach maturity until last of December. I have found the same gall 

 on the Post Oak at Asheville, N. C. Baron Osten Sacken mentions 

 having found this species in his second paper on North American 

 Oak Galls 1862, p. 255, from whom the description of the gall is 

 taken ; he did not, however, breed the fly. 



9. .4n(lrioiis» ciiiiiaiiionioiis n. .sp. 



Gull- — A small, cone shaped bud gall .35 to .40 iuch long by .1.5 to .17 inch in 

 diameter, covered with short deformed leaf scales. The egg is evidently de- 

 posited in the fall or midsummer, causing an abnormal development of the bud 

 and bud scales, which cover the gall. The larval cell is thin, whitish in color, 

 cocoon shaped and attached to one side, at the base of the gall. One might easily 

 cut into and open the gall without finding it, for unless he accidentally cuts into 

 the side where the cell is situated, it would remain undiscovered. 



Gall-flt/. — ^9 Length .10 inch. Color a uniform bright cinnamon red. excepting 

 the dark brown or l)lack eyes. Antennae 13-jointed, reaching beyond the base of 

 the abdomen ; head and thorax punctate, sparsely pubescent, parapsidal grooves 

 well defined ; legs sparsely pubescent ; abdomen ovate, second segment prolonged ; 

 sheaths porrect, ventrally ; w'ings glassy hyaline, veins pale, the areolet and 

 cubitus obsolete, although in two specimens they are faintly traceable. 



Described from several specimens bred April, 1887. Occurs on 

 Querciis parvifolia. 



10. Aiidrictis? floridaniis n. sp. 



Galls. — Hard, irregular swellings of a branch or the stem close to tlie ground, 

 never very high up, from half an inch to three or more inches long by not more 

 than half an inch in diameter. Some specimens might easily be confounded with 

 Andriciis batatokles m., Andricus medullse m., or Neuroterus Rile.yi Ba.ss., but the 

 gall producer is very distinct from any of these. 



Gall-fly. — % 9- Length .12 to .17 inch. Color dark brown, abdomen reddish 

 brown polished. Antonnse 9 l^i '^ 1~ jointed, as long as the whole body, slen- 

 der, nearly the same thickness throughout. Head and thorax punctate, pubes- 

 cent, cheeks well rounded ; scutellum cushion shaped, pubescent, foveie indistinct ; 

 abdomen ovate, slightly compressed ; wings hyaline, veins brown, radial vein 

 reaching costal edge; areolet distinct; cubital cell closed, tlie cubital nervure 

 does not quite reach apical margin. 



Described from several specimens. This species in ifcj antennal 

 characters is very distinct from any described species in the Cynipinae, 

 no 9 yet described having sixteen joints in the antenna^ ; but it 

 seems so closely related to the genus Andricu.-i that it may be placed 

 there temporarily. It is found on (^. purcifolia.
