110 THE CANADIAN ENTOMOLOGIST 



TWO XFAV GENERA OF NORTH AMERICAN 

 ENTEDONIN^ (CHALCID-FLIES). 



BY A. A. GIRAULT, GLENNDALE, MD. 



Elachertodomyia, new genus. 



Type. — Secodes pMceotribi Ashmead. 

 Tarsi 5-jointed; hind tibial spurs double; antennae inserted slight- 

 ly above the ventral ends of the eyes, 13-jointed, 3 ring, 5 funicle 

 joints, the three club joints not very distinctly divided, especially 

 the small last, the latter without a terminal spine. Funicle joints 

 all somewhat wider than long, the first longest, slightly shorter 

 than the normal pedicel. Head rounded from cephalic aspect. 

 Venation normal, the marginal vein a little over two-thirds the 

 length of the submarginal, the postmarginal elongate, nearly as 

 long as the marginal, twice the length of the short stigmal, the 

 stigma being larger than usual. Several lines of the fine discal 

 ciliation, notably one from the stigma to blade apex, regular and 

 distinct. Parapsidal furrows distinct. Propodeum short. Scutum 

 long. Scutellum subquadrate, its lateral margins delicately in- 

 dented, appearing as lateral, grooved lines but not these as usually 

 understood. Scutellum with not more than four bristles. Strigil 

 strong, the cephalic tibial spur forked. Propodeum with a weak 

 median carina. The original description of the genotype is 

 correct. Its bod>' is scaly. 



From the female type of genotype, now remounted on a tag in 

 the U. S. National Museum, the antenna, a fore wing, a middle 

 tarsus and a hind leg together on a slide. 



This genus is certainly very anomalous. I doubt if it is an 

 eulophid, because of its two hind tibial spurs, the forked tibial 

 spur of the cephalic legs and the five tarsal joints. 



Emersonopsis, new genus. 



Type. — Entedon arizonensis Ashmead. 



Original description correct. All the tarsi concolorous. 

 Antennae 9-jointed with two rather large ring-joints, the club 3- 

 jointed, the funicle 2-jointed, club with a short, terminal nipple. 

 Pedicel much longer than wide, slightly longer than funicle 1 ; 

 funicle 2 subglobular. Postmarginal vein shorter than the very 

 short, sessile stigmal. Propodeum medially produced into a neck 

 like the abdominal petiole, the latter very short and ventrad of the
