ART. 28 CHALCID FLIES NOETH OP MEXICO BALDUF 47 



podeal surface more or less uniformly reticulate behind the branches 

 of the anterior carina; submarginal band with about 12 setae in a 

 row; abdominal segments one to three smooth, but not highly pol- 

 ished, at least sides of fourth finely roughened, granulose, moder- 

 ately hairy, and punctate at the ovipositor sheath. 



Male. — Unknown. 



Type locality. — Paso Kobles, Calif. 



ry;?e.— Female, U.S.N.M. No. 42237. 



Doctor Kinsey sent me all the type material. It consists of two 

 females, one of which I have designated the type, reared from the 

 galls of Neuroterus quercicola faci-fiGUB.^ form varians Kinsey, on 

 Qnercus lobata, at Paso Robles, Calif., and six other more or less 

 fragmentary females reared from the galls of Andricus wiltzae 

 Fullaway on the same oak in the same locality as the first two speci- 

 mens. The gall makers of these lots issued March 7, 1920. Three 

 paratypes are in the United States National Museum with the type. 

 The other paratypes are in my own collection. 



17. DECATOMA GLOBULI. new species 

 Plate 2, Figxjke 16 



Similar to D. novascotiae, new species, in size and in having a 

 narrow, curved submarginal band. The body of glohuli is less ro- 

 bust, particularly the head is less blocky, and the color in general 

 is more black than in this species. 



Female. — Length 2.1 to 3 mm., color more black than yellowish 

 brown; head mostly black, usually with more or less j^ellow-brown 

 in circumoral area, this color sometimes extending to antennal fos- 

 sae and including malar space, and branching along lateral margins 

 of antennal scrobe to frons and also around eyes, forming a narrow 

 circumocular band, a rather faint oblique band arising from latter 

 on vertex reaching toward upper limit of scrobe, and dilating more 

 or less on temples, or including genae entirely, the scrobe black; 

 scape yellow with variable longitudinal black bands laterad, pedicel 

 mostly brown, apex above and apical half below yellow, ring joint 

 yellow, flagellar joint yellowish brown, infuscate above; pronotum 

 usually mostly black, at least a yellow triangle on anterior lateral 

 half, sometimes the whole side of the pronotum yellow, and on 

 some specimens the anterior lateral area of the dorsum, and at times 

 also the neck in part, yellow; prescutum, scutellum, most of scapu- 

 lae and axillae above, metapleura, and propodeum, black; scapulae 

 and axillae otherwise, and mesopleura, rufous-yellow, latter some- 

 times partly lightly infuscate; coxae black except apices, or mixed 

 yellow and brown, trochanters yellowish, femora same but superior 

 faces of front and middle femora, and inner and outer faces of hind
