and the other in New York (Coll. U.S. Nat. Mus.). In the former the 
abdomen is very narrowly black centrally, and only on three or four 
basal segments. A female (Coll..U.S. Nat. Mus.) taken June 26, at 
Garland, Colo., is also provisionally placed with this species. It agrees 
in coloration with the Maine specimen, and also in structure, except that 
the sheath of the ovipositor is broadened basally. 
17. Amauronematus chalceus new species. 
Female.—Leugth 10 mm.; large, rather robust; clypeus deeply and 
broadly emarginate, lobes large, rounded; ocellar basin distinctly 
defined; frontal crest prominent, not or but slightly broken, extending in 
an indistinct ridge to the orbits; antennal fovea large, triangular, rather 
deeply excavated; antenne distinctly tapering, third and fourth joints 
very much longer than fifth, third longest; third submarginal cell 
elongate, sides parallel; upper discal cell of hind wings considerably 
exceeding lower; sheath broad, tapering, slightly constricted before 
apex, with distinct scopa at tip; cerci short, slightly constricted at base; 
claws deeply and evenly notched. Color reddish yellow or resinous; 
antenn with circle about base extending downward to clypeus, ante-

more or less of center of basal plates, prothorax beneath, and lower half 
of mesepimera brownish black; ocellar region, posterior tarsi, and tip 
of sheath more or less infuscated; wings slightly infuscated, especially 
between stigma and posterior border; veins and stigma dark brown,

Two females. Olympia, Wash. ‘'T. Kincaid, collector. (Coll. Cornell 
Univ.) 
18. Amauronematus coquilletti new species. 
Female—Length 8 mm.; robust; clypeus broadly, rather deeply 
notched, lobes large, rounded; ocellar basin distinctly defined, lateral 
walls not strongly raised; frontal crest slightly broken by the back- 
ward extension of the deep and sharply defined oval antennal fovea; 
antenne stout, longer than head and thorax, slightly tapering, densely

dish; antenn, small spot including ocelli with branches running down 
toward bases of antenn, stripe on each of anterior lobes of meso- 
notum, metanotum for the most part, ventral sclerites of prothorax, 
and lateral sclerites of metathorax black or dark brown; extreme tip 
of sheath brownish; wings hyaline or slightly smoky from rather dense 
pubescence; veins uniformly light yellowish brown; stigma and costa 
somewhat paler. 
One female. Los Angeles, Cal. Mr. D. W. Coquillett, collector.
