ART. to GALL-INHABITING CYNIPID WASPS WELD 17 



flies were reared from either host. Morrison sent galls to Washing- 

 ton in 1882 from Fort Grant and Hubbard sent galls from the 

 Chiricahua Mountains in 1897. 



DIPLOLEPIS AMPHORA, new species 



Female. — Red, darker on abdomen and between parapsides in 

 front. Head coriaceous, from above scarcely broadened behind 

 eyes, occiput not concave; from in front pubescent on face, facial 

 quadrangle one and one-fourth times as broad as high, malar 

 space .4 eye without groove, antenna 14-segmented lengths as 

 (scape) 10^:6:11:10:9:8:7.5:7.5:7:7:7:6:5.5:8. Sides of pro- 

 notum pubescent. Mesoscutum broader than long, shining, smooth 

 behind, coriaceous and with setigerous punctures anteriorly, parap- 

 sidal grooves deep, smooth, narrow, percurrent. Disk of scutellum 

 smooth above, rugose behind, sides bounded by straight lines diverg- 

 ing behind, groove at base indistinctly divided into two pear-shaped 

 pits. Carina? on propodeum strongly curved, neck rugose. Meso- 

 pleura smooth. Tarsal claw with a weak tooth. Wing ample, 

 hyaline, pubescent, ciliate, first abcissa of radius arcuate Avith slight 

 cloud on upper half, second nearly straight, radial cell nearly four 

 times as long as broad, areolet reaching one-sixth, cubitus two-thirds 

 way to basal. Abdomen as long as head and thorax, lengths of 

 tergites along dorsal curvature as 62 : 13 : 12 : 3 : 1 : 4, second pubes- 

 cent at base, its hind margin oblique, ventral spine slender, in side 

 view about six times as long as broad. Using width of head as a base 

 the length of mesonotum ratio is 1.4, antenna 2.6, ovipositor 2.4, 

 wing 5.0. Length 1.4-2.2 mm. Average of 31, 1.85 mm. 



r//;)e.— Cat. No. 27186, U.S.N.M. Type and 9 paratypes. Para- 

 types at American Museum, Field, Stanford, and Philadelphia 

 Academy. 



Host. — Quei'cus undulata. 



Gall (fig. 31). — A hollow cylinder, sessile at base, swollen more 

 or less in the middle and tapering to the apex which is contracted 

 to a small hole leading into a deep cavity in the bottom of which 

 and in the basal third of the gall is the thin-walled larval cell below 

 which a small cavity leads to the pedicel. Red or brownish, 4-5 mm. 

 high by 3 mm. in diameter, the hole at apex about 1 mm. in diameter. 

 Occurs in fall and drops with the leaves, usually only one or two on 

 a leaf near the edge on under side. 



Hahltat. — The type is selected from material collected on Q. un- 

 (hdata at Tijeras, N. Mex., November 1, 1921, when some of the galls 

 contained pupae and others adults. Paratypes are from Q. undulata 

 in Blue Canyon west and Nogal Canyon south of Socorro, the living 

 flies cut out of the galls January 3, 1922. Other paratypes are from
