Pedicel shorter than the first joint of the funicle or no longer, the first three joints of the fmiicle obconi- 

 cal ; abdomen conically pointed, with the segments, except the second, which is the longest, nearly 

 of an equal length (sexual form) Philachyra Haliday (type P. ips Hal.). 



7. Mesonotum and scutellum highly polished, impuncfcate ; abdomen conic-ovate, as long as the head and 



thorax united ; antennse 11-jointed, the funicle 5-jointed, the first joint the longest, obconical, longer 

 than the pedicel (Agamic form) Philachyra Haliday. 



8. Marginal vein always longer than the stigmal vein 9 



Marginal vein shorter than the stigmal vein. 



Head and thorax umbilicately punctate, the former with a deep frontal furrow ; flagellum fili- 

 form, the joints of the funicle long, three or more times longer than thick, briefly pedicellate 

 at apex, with two whorls of long hairs on each joint Isosomodes Ashmead. 



9. Metathorax not abruptly and squarely truncate behind, either sloping or rounded 10 



Metathorax quadi'ate, abruptly and squarely truncate behind ; head and thorax umbilicately punctate. 



Isosomorplia Ashmead. 



10. Thorax smooth and shining, impunctate or at the most very feebly, microscopically shagreened. . . 13 

 Thorax more or less distinctly umbilicately punctate, finely punctate, or coarsely shagreened, 



opaque 11 



11. Head and thorax finely punctate 12 



Head and thorax more or less umbilicately punctate or coarsely shagreened. 



Mesonotum more or less distinctly umbilicately punctate, not finely transversely aciculate ante- 

 riorly ; funicle joints long, more than thrice longer than thick, constricted or briefly pedicellate 

 at apex, with indistinct whorls of long hairs Isosoma Walker. 



Mesonotum not so punctate, the middle lobe smoother, delicately punctate, with usually delicate 

 transverse aciculations anteriorly Euoxysoma Ashmead. 



12. Metathorax elongate ; abdomen clavate, the petiole slender, punctate, as long as the hind coxse, the 



body a little longer than the thorax ; antennje filiform, slender, pubescent. 



Aiolomorphus Walker (type^. rhopaloides Walk.). 



13. Funicle joints long, subcontracted near the middle and subpetiolate at apex, each joint with two, some- 



what irregular, whorls of long hairs Isosomocharis Ashmead. 



Funicle joints long, jjetiolate or subpetiolate at apex, with long hairs, but not arranged in two Avhorls 

 and the joints cylindrical, without a median contraction ; abdomen oblong-oval, the petiole rugulose, 

 about twice as long as thick or a little longer, the second segment the longest segment, longer than 

 the third and fourth united, the latter about equal with those beyond Philachyra Haliday. 



Tribe III. Euri/tomini. 



This is the most extensive tribe in the family and the National Museum collec- 

 tion contains many undescribed species. All of the species are genuine parasites 

 and destroy the larvte of several orders, Hymenoptera, Diptera, Coleoptera, etc. 



Dr. A. D. Hopkins, of the West Virginia State Agriculture College, claims, 

 however, that Bruchophagus {Earj/loma) fanehris Howard is phytophagous and 

 states he has proved it by a series of experiments. I think, however, some mistake 

 has been made and I cannot accept Dr. Hopkins' observation as conclusive. Dr. 

 Howard described it as having been bred from Cccidomijin IiujuwAcola Lintner, living
