coarsely striate on its basal two-fifths. Legs, including- coxae pallid 
yellow, the posterior coxae rugose. 
Aside from its punctate body, this species may be distinguished 
from C. melanocerus Ashm. by its acute metathoracic angles ; from 
C. pedalis Ashm. by its dark wings, and from C. glaber by the 
length of the antennal joints.

Telenomus heracleicola sp. nov. 
Female. Length 1.25 mm. Black ; legs yellowish red, with black 
coxae ; antennal scape yellowish at base ; mandibles except tip and 
palpi, yellow. Head two and one-half times as wide as long, the front 
highly polished medially, on the sides shagreened ; hollowed out just 
above the antennae, the depression divided by a short median carina; 
vertex shagreened. Eyes very faintly pubescent. Antennae rather 
slender, the flagellum almost two times the length of the scape. Pedicel 
narrowed at base, at the tip wider than the first flagellar joint ; first 
flagellar one and one-third times the length of the pedicel and one and 
one-half times as long as the second ; third and fourth monilif orm. 
Club five-jointed, the three middle joints largest, quadrate, last joint 
scarcely longer than the penultimate. Thorax oval, the mesonotum

Male. Similar, but the antenn-c are filiform, the flagellum two and 
one-half times the length of the scape, the pedicel two-thirds the length 
of the first flagellar joint, the second flagellar about one-third longer 
than the first ; fourth and following decreasing, the last equal to the 
pedicel. 
Described from four females and one male sent me by my 
friend Professor A. L,. Melander. He tells me that they were 
reared from butterfly eggs collected on a species of Heracleum, at 
Pullman, Washington.
