27. (2) Chiloneurus dubius, n. sp. 
Male. — Length, 1.05 mm ; expanse. ■>.:i mtu : width of fore vring, 137 . A nr.-Tin.i-. 
li^ht brown : face, honey-yellow, brownish towards vertex ; pronotum, mesosentnm, 
and axillae black, with silvery-white hairs on pronotum and scutum: axillae finely 
punctured; mesoscutellnm bright rust-red, with a loose tuft of black hairs at tip; ab- 
domen black, with a coppery luster ; tore 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 8 specimens, parasitic in all probability, on a species 
of Lecanium (probably and escribed) from Scotch and Dwarf Mountain 
Pine, collected in 1874, at Lancaster. \Yi>;.. by A. W. Barber, and later 
at St. Louis. [O. V. R. Coll.] 
28. (3) Chiloneurus dactylopii, n. sp. 
A large number of specimens of a species of Chiloneurus was bred 
from a common " mealy bug" (Dactylopius destructor Com St.), on the 
garden Pseonia 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/o> -moms 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 Aphyots Mayr. 
Female.— Antenme 11-jointed. moderately short, inserted near the month : 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 oompn 
Face, vertex, and dorsum of thorax are lusterless and finely punctate, frequently 
clothed with yellowish hair. Ovipositor usually not protnding. The marginal vein is 
not developed, and the stigmal is given offal the juncture of the submarginal with 
the costa. 
Male — Distinguished by the antenme. in which the pedicel is longer than the suc- 
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 tirst 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 mm ; expanse of wings, 2.12""™; greatest width of fore wings, 
n. u •. Scape of autennse not broadened; ovipositor slightly exserted. Bead very 
delicately shagivencd : mesosentnm, scapulas, and mesosoutellum thickly but not 
deeply punctured: punctures of inesosoutum and scapulae transverse oval, and of 
■cn tell am longitudinal oval, converging toward the anterior angle; posterior border 
of tnesoscutellnm smooth, as is also the metanotum. General color yellow-brown, yel- 
low below ; scape and pedicel of antenme brown, flagellar join's yell -wish, club 
brown: all coxa' brown; front femora, tibia-, and tarsi yellowish white, with a faint 
brownish patch on the dorsal side of femora and tibise ; middle femora and tibia
