30 PEOCEEDINGS OF THE NATIONAL MUSEUM vol. 79 



tate above, punctures contiguous, larger on scutel, mesopleura acicu- 

 late and finely punctate, the silvery bunch of hairs conspicuous on 

 metapleura; about 13 setae on submarginal vein; abdomen bare ex- 

 cept that ovipositor sheaths and last segments are moderately to 

 sparsely hairy, entire tops and sides of the segments shagreened. 



Male. — Unknown, 



Type locality. — Jacksonville, Fla. 



Ty;?^.— Female, U.S.N.M. No. 2820. 



Redescribed from type and four female paratypes from the same 

 locality as the type. One of the paratypes is in the writer's collection 

 on a slide. The species was originally described from five female 

 specimens; "four captured at large and one bred from cynipidous 

 live oak root gall DryorMzoxenus floridanus Ashmead " by Doctor 

 Ashmead. Three other old specimens, two labeled " Jacksonville, 

 Fla.," may be this species. 



RerriOfrks. — No additional material of this species has been collected. 

 I suspect that this may be identical with D. fiava Ashmead, but am 

 allowing it to stand as distinct until further specimens can be obtained 

 from the above host. The types differ from -flava in being darker in 

 body color, but this seems to be an abnormal or perhaps tarnished 

 color shade. The wing band of most specimens of hicolor bulges 

 more on the distal margin than on flava. Furthermore, the unique 

 type of gall from which some of Ashmead's specimens were obtained 

 strengthens the probability that they are a distinct species. 



11. DECATOMA ISIS Giranlt 



Plate 1, Figure 9 



Decatoma isis Giraui--t, Descriptioues stellarum iiovarum, pp. 10-11, 1917. 



From the same genera of Cynipidae as D. varians Walsh, and has a 

 " bottle-shaped " submarginal band like that species ; isis differs in 

 being larger, darker on the average, in having slenderer antennae, in 

 having 15 to 18 setae on the submarginal vein, and the head almost 

 twice as wide as long, or nearl}^ the shape and dimensions as on IK 

 dtihia Walsh. 



Female. — ^Length 3.3 to 4.6 mm.; colors chiefly black and rufous- 

 yellow, variable; vertex usually mostly black, but at least band 

 along eyes and oblique stripe from it to top of antennal scrobe 

 reddish yellow, occiput at times almost entirely black but usually 

 in part not so, temples and cheeks largel}^ black with at least hind 

 edge black, malar space and front varying extremely from entirely 

 rufous or reddish yellow to mostly black, margins of eyes and anten- 

 nal scrobe, region of mouth to lower end of scrobe, and malar 

 groove usually not black; scape dull yellow, pedicel mostly brown, 

 apex yellowish, funicle chestnut-brown, club darker; pronotum
