Genus EURYTOMOCHARIS Ashmead. 
Eurytomocharis eragrostidis n. sp. (fig. 8). 
Female. — Leugth, 1.8 mm; expanse, 4 mm. Head and. thorax very 
faintly shagreened, with minute umbilicate punctures on pronotuni 
and larger ones on mesoscutellum ; metanotum with central longitud- 
inal suture complete, but not emarginate. Abdomen shorter than tho- 
rax; joint 4 as long as 2 and 3 together; 2 and 3 subequal; 5 and 6 
short. Antennae with globose funicle joints; joint 1 of funicle a little 
longer than pedicel, others subequal; club ovate, a little longer than 
funicle joints 4 and 5 together. All legs, including coxae, dark yellow 
brown. 
Male. — Length, 1.2 mm; expanse. 2.0' mm. Petiole faintly sculp- 
tured, as long as hind coxae; antenna 1 with the 5 funicle joints strongly 
arched above and pedicellate; the body of each joint nearly as wide as

long; scape broad, slightly widened below; pedicel globose; club as 
long as two preceding funicle joints together, not obviously divided. 
Described from very many male and female specimens reared Sep- 
tember, 1885, and March, 1886, from stems of Eragrostis poceoides, 
collected at Lafayette, Ind., by F. M. Webster. The infested grass 
stem is as a general thing not at all or very slightly swollen. The 
larva excavates it for a distance of an inch or more and issues from a 
round hole. The first or second joint below the head seems to be the 
portion of the grass most commonly attacked. 
Eurytomocharis triodise n. sp. 
Female. — Length, 3.2 mm.; expanse, 5 mm. Resembles closely the 
foregoing species, except that it is considerably larger. Head, pro- 
notum, and mesonotum coarsely umbilicate-punctate; metanotum with 
very shallow emarginate central furrow with transverse rugosities
