ing anteriorh' and below ; propocleiim coarsely morose, with a promi- 

 nent median longitudinal carina; stigma a little shorter than meta- 

 carpus and hardly twice as long as broad; radius arising tar out 

 on stigma, the inner side of the latter about twice as long as the 

 outer; radius tending strongly outward, much longer than the iirst 

 intercubitus; posterior coxae large; inner spur of middle tibiae at 

 least as long as middle metatarsus ; inner spur of posterior tibiae 

 much more than half as long as the posterior metatarsus ; abdomen 

 broad, stout, nearly as long as the thorax; the first tergite very 

 large, broadening toward apex, where it is nearly as broad as long, 

 very coarsely rugose; second tergite transverse, longer than third, 

 and three times as broad as long, entirely coarsely rugose; third 

 tergite somewhat punctate and indistinctly striate on basal half, 

 polished beyond; the following tergites smooth and polished; 

 liypopygium strongl}?^ developed : ovipositor sheaths more than two- 

 thirds as long as the abdomen, broad, broadest a little beyond tho 

 middle, from which point the}' taper somewhat toward apex. Black; 

 mouth parts and antennae usually blackish; tegulae and wing-bases 

 transparent-yclloAv ; wings entirely hyaline, the veins and stigma 

 dark brown, the latter pale at base ; legs, including all coxae, testace- 

 ous, except extreme apex of posterior femora, the apical third of 

 l^osterior tibiae, and the posterior tarsi, which are fuscous ; abdomen 

 black; the venter testaceous on basal half; ovipositor sheaths black. 



Type locality. — Agricultural College, Mississippi. 



Type.—Ciit. No. 23991, U.S.N.M. 



Host. — Pyrausta ainslei Heinrich ; Diatraea^ species. 



Described from two female specimens, the type reared from Py- 

 rausta ainslei, by K. W. Harned, August 23, 1920, at Agricultural Col- 

 lege, Mississippi ; the paratype reared from a Diatraea larva in corn- 

 stalk, at Bentonvilie, South Carolina, August 31, 1915, by E. R. 

 Barber. 



16. MICROGASTER PANTOGRAPHAE, new species. 



Very similar to harnedi, also to gelechiae. It differs from the 

 former in the much longer stigma, the basally black posterior coxae, 

 and in the ovipositor sheaths being broadest at apex ; from gelechiae 

 it is distinguished by the clear hyaline wings, and by the apex of 

 the posterior tibiae and the posterior tarsi being strongly inf uscated. 



Female.— L^Tigih 4.2 mm. Face confluently punctate and shining, 

 with a short polished median carina below antenna! fossae; vertex 

 almost impunctate ; temples weakly punctate and shining ; mesoscu- 

 tum weakly punctate anteriorly, impunctate and polished behind; 

 scutellum impunctate and highly polished; mesopleurae shallowly 

 punctate and strongly shining anteriorly and below, polished pos-
