27. (2) Chiloneurus dubius, 2. sp. 
Male.—Length, 1.05™™; expanse, 2.5™™; width of fore wing, 0.37™™, Antenne 
light brown; face, honey-yellow, brownish towards vertex ; pronotum, mesoscutum, 
and axille black, with silvery-white hairs on pronotum and scutum; axille finely 
punctured; mesoscutellum bright rust-red, with a loose tuft of black hairs at tip; ab- 
domen black, with a coppery luster; fore wings with a small dusky patch below 
stigma. Front and middle legs light yellowish throughout; hind legs black through- 
out, with the exception of a whitish femero-tibial articulation and the first three 
white tarsal joints. , 
Described from 4 ¢ specimens, parasitic in all probability, on a species 
of Lecanium (probably undescribed) from Scotch and Dwarf Mountain 
Pine, collected in 1874, at Lancaster, Wis., by A. W. Barber, and later 
at St. Louis. [C. V. R. Coll.] 
28. (5) Chiloneurus dactylopii, n. sp. 
A large number of specimens of a species of Chiloneurus was bred 
from a common ‘“ mealy bug” (Dactyloptus destructor Comst.), on the 
garden Ponia on the Agricultural Department grounds, at Washing- 
ton, late in November, 1884. It is impossible to distinguish the female 
of this species from that of the European C. formosus Boh., as I am in- 
formed by Dr. Mayr; but the males of the two species are readily dis- 
tinguishable by the relative lengths of the marginal and stigmal veins. 
In formosus the marginal is twice as long as the stigmal, while in dacty- 
lopii it is only slightly longer. [Dept. Agr. and C. V. R. Coll.] 
Genus APHYCUS Mayr. 
Female.—Autenne 11-jointed, moderately short, inserted near the mouth; scape 
widened or cylindrical; pedicel about twice as long as thick; the joints following 
the pedicel are thicker than long, and increase in thickness by degrees; the club is 
about as long as the three preceding joints, and is obliquely rounded, often compressed. 
Face, vertex, and dorsum of thorax are lusterless and finely punctate, frequently 
clothed with yellowish hair. Ovipositor usually not protuding. The marginal vein is 
not developed, and the stigmal is given off at the juncture of the submarginal with 
the costa. 
Male.—Distinguished by the antenna, in which the pedicel is longer than the sue- 
ceeding joint (this is so also with the female but not with the males of allied genera). 
The flagellum is uniformly clothed with hairs; the first joints are longer than thick, 
and the club only so long as the two preceding joints. 
29. (1) Aphycus brunneus, n. sp. 
Female.—Length, 1.06" ; expanse of wings, 2.12™™"; greatest width of fore wings, 
0.41™™, Scape of antenn# not broadened; ovipositor slightly exserted. Head very 
delicately shagreened; mesoscutum, scapulie, and mesoscutellum thickly but not 
deeply punctured; punctures of mesoscutum and scapule transverse oval, and of 
acutellum longitudinal oval, converging toward the anterior angle; posterior border 
of mesoscutellum smooth, as is also the metanotum. General color yellow-brown, yel- 
low below; scape and pedicel of antennie brown, flagellar joints yellowish, club 
brown; all coxw brown; front femora, tibiw, and tarsi yellowish white, witha faint 
brownish patch on the dorsal side of femora and tibiw; middle femora and tibiw
