AKT. 28 CHALCID FLIES NOETH OF MEXICO BALDUF 87 



inconspicuous stripe from each antennal fossa to base of mandibles, 

 and oral area narrowly, brown, palpi light yellow, gula light brown ; 

 scape light lemon yellow, almost stramineous, pedicel yellowish brown 

 above, sometimes darker on sides, ring joint and fiagellum light yel- 

 lowish brown; dorso-cephalic corner of pronotum yellow, rest of 

 thorax, including propodeum, black, tegulae brown ; legs yellow, but 

 all coxae black, and tarsi stramineous; stigma not densely brown; 

 peduncle and abdomen entirely black. 



Head always distinctly twice as wide as long, face almost flat, 

 scarcely protruding beyond a straight line tangent to front edge of 

 eyes, vertex elevated somewhat abruptly between hind ocelli, upper 

 hind edge of head quite straight, occiput broadly concave, temples 

 fairly prominent, hence head from above strongly rectangulate-ovate ; 

 vertex feebly umbilicate and finely and densely punctate, malar groove 

 entire, malar space reticulate-punctate, and sparsely hairy like genae 

 and face; pedicel slightly more than twice as long as its greatest 

 width at apex, and one-fourth longer than Fl, latter a fourth longer 

 than thick and only slightly longer than F2, F2 to F5 subequal, F2 

 and F3 each a bit longer than thick, F4 and F5 scarcely longer than 

 wide, club as long as F5, F4, and a third of F3 combined ; pronotum 

 narrower than head and mesothorax, and thorax rather coarsely 

 umbilicate above, moderately hairy, front of mesopleura finely punc- 

 tate, hind half aciculate-punctate ; submarginal vein with a row of 

 16 to 17 setae; propodeal surface quite coarsely and variously sculp- 

 tured, nearly reticulate, groove fairly deep, posterior two-thirds 

 crossed by several subparallel rugae, the anterior third polished, and 

 limited in front by a V-shaped carina with a rather sharply rounded 

 apex ; abdomen polished, smooth, and bare, except area of ovipositor 

 sheath hairy and punctate. 



Male. — Unknown. 



Tyfe locality. — Jacksonville, Fla. 



ry;?^.— Female, U.S.N.M. No. 20868. 



Remarks. — Girault's original description was based on the type 

 and a female paratype in the United States National Museum and 

 collected at the type locality by W. H. Ashmead. No further facts 

 are known about this material. In studying the National Museum 

 specimens of this genus I have found eight additional individuals 

 of this species that no doubt belong to the original lot taken by Ash- 

 mead but were overlooked by Girault. They bear the same locality 

 label as the types, and agree with them in color and structural 

 features. On one of the pins is written "^. foccir which is the 

 only hint we have concerning the host of this species. A. flocci is 

 Andricus flocci (Walsh), which forms galls on Querciis alhn. 



It is of interest that no males are known. It is possible that some 

 specimens of that sex belonging to this species are confused with the
