AET. IS. NOTES ON CYNIPID V/ASPS — WELD. 19 



occur on Q. chrysolepis, as Ashmead stated, but on Q. xoislizeni and Q. 

 agrifolia. Q. chrysolejns^ and Q. agrifolia have no galls in common ; 

 wlslizeni and dgr'ifolia have many. The new galls start in early 

 xipril and are full grown by early May, While growing rapidly 

 they secrete honey-dew. 



CALLIRHYTIS CRYPTICA. new species. 



Female. — Dark reddish-brown. Head coriaceous. Interocular 

 space, 0.5 t'ransfacial, and area 1.25 times as broad as high. Malar 

 space, 0.5 eye, with striae. Antennae slender, 13-segmented ; lengths 

 as (pedicel) 13:6:11:12:11:11:10:9:8:7:7:7:14. Sides of pro- 

 iiotum coriaceous. Mesoscutum broader than long; coriaceous, 

 parapsidal grooves deep and complete, median reaching forward 

 nearly half-way. Scutellum coriaceous; usual pits oval, smooth, 

 very oblique, separated by a septum wider than a pit. Median area 

 on metanotum as broad as the area on propodeum betAveen the 

 carinae, these carinae nearly parallel inclosing a smooth area broader 

 than long. Veins of fore wings obliterated beyond second cross- 

 vein, others pale; no areolet; surface short pubescent; margin not 

 ciliate. Hind tarsus as long as tibia; claws simple. Abdomen 

 shorter than head and thorax, broader than long in side view, with 

 interrupted ring of wool at base, only tergites 2 and 3 showing dor- 

 sally; ventral valves not conspicuous; ventral spine very long and 

 slender, twice as long as hind matatarsus; this character hard to see 

 in pinned specimen. Ovipositor hooked at end. Using width of 

 head as a base, the length of mesonotum ratio is 1.09; antenna, 2.G: 

 ovipositor, 4. ; wing, 3.5. 



Range in length of eight specimens, 1.9~2.1 mm., average 2 mm. 



Type.— C'At. No. 24725, U.S.N.M. Type and six paratypes. 



E-ost. — Quercus falcata and Quercus myrtifolia. 



Gall. — A bud gall found in October. The affected bud in terminal 

 cluster becomes enlarged, leaf rudiments are protruded beyond the 

 bud scales, and then the whole thing turns brown, although one or 

 two green leaves sometimes grow out of this seemingly dead bud. 

 Completely hidden within is an axial, conical, thin-walled cell with 

 a tuft of hairs near apex, filling the whole interior of bud. It some- 

 what resembles the gall of Andricus mmmnomeus Ashmead, which is 

 also within a swollen bud but on Q. chapmuni. Its covering of bud 

 scales is intact, and within is a central cavity, on one wall of which 

 is the larval cell, which is therefore eccentric instead of axial. 



Ilahitat. — The type galls were collected at Dothan, Alabama, on 

 Q. falcata, October 8, 1919. Flies issued May 1 and May 23, 1920. 

 These galls were seen also at Cottondale, Florida. At Carrabeile and 

 at Ocala, Florida, they were collected on Q. myrtifolia and one fly
