yellowish white, each with a median brown annulation, tarsi yellow ; hind femora 
and tibize brown, white at base of femora and at base and tip of tibie, tarsi yellow- 
ish white; wing veins yellowish, dusky at origin of stigmal. 
Described from 19 specimen; ¢ unknown. 
Bred, November, 1874, from specimens of Diaspis rose received from 
Mrs. Mary Treat, Vineland, N. J. [C. V. R. Coll.] 
30. (2) Aphycus ceroplastis, n. sp. 
Female.—Length, 1.4™™; expanse, 3.3"; greatest width of fore wing, 0.51™™, 
Antennal scape with a slight expansion below near tip; club flattened, oval. Me- 
soscutellum with a slight longitudinal median impression ; ovipositor well exserted ; 
ocelli form an acute-angled triangle. Color: Autennal scape yellow, with a black 
stripe near base and another near tip, including the expansion, and broadest on the out- 
side ; basal half of pedicel black, distal half light yellow ; funicle brownish at joint Ly 
each joint growing lighter in color to joint 6, which is yellow; club, dark brown, 
nearly black, sometimes lighter at tip; head and face yellow, with a large brown spot 
on each cheek, occiput brown; pronotum black, mesoscutum and axille yellow, with 
a dusky shade towards the pronotal border of the mesoscutum ; mesoscutellum black, 
metanotum also black ; tegulie yellow, dusky at tip; abdomen black above, yellowish 
beneath, especially near base; ovipositor yellow ; the conspicuons shields at the sides 
of the body (which may possibly be homologized with the epimera of the mesothorax) 
are shiny black, yellow at bases; all legs yellowish: wings hyaline. 
Male.—Length, 1.047"; expanse, 2.4™™; greatest width of fore wings, 0.42™™. 
Flagellum of antenne of a uniform light brown; brown spots on cheeks lacking ; 
mesoscutum and axillie black; hairs on the abdominal spiracles very conspicnons. 
Variety a.—In four 2’s the marked appearance of the mesonotum, produced by the 
contrast of the yellow mesoscutum and axille with the black mesoscutellum and pro- 
notum, was lost by a black shade in the middle of the mesoscutum, and the axille 
were black asin the @. 
Described from 8 2’s, 2 ¢’s, and 4 2’s of variety a; all bred from 
scales of Ceroplastes artemesie Riley MSS., collected in 1879, on Arte- 
mesia, at Silver City, N. Mex., by H. H. Rusby. The parasites issued 
in the latter part of March. [C. V. R. Coll.] 
31. (3) Aphycus maculipes, n. sp. 
Female.—Leneth, 1.4™™; wing expanse, 3.00"™; greatest width of fore wing, 0.58™™. 
In all respects, except in size and details of coloration, similar t» Aph. pulvinaria, 
Howard. The scape, which is greatly widened below, is shining black in color, with 
a white band at base and a white tip. Pedicel black, lighter towards the lateral por- 
tionof thetip. Joints1, 2, 3, and 4 of the funicle black, the inner surface of 4sometimes 
lighter; club dark brown. Face and front rust-red and hairless; ocelli coral-red, 
placed at the corners of an acute-angled triangle; occiput black nearly to the eyes. 
Anterior face of pronotum black with light yellow sides and a yellow transverse stripe 
dorsally; dorsal surface of pronotum of a pale bluish color, with whitish hairs, and 
furnished at each angle with a distinct round black spot. Tegule whitish, dusky at 
tip. Mesonotum ferruginous; metanotum dusky. Abdomen blackish above, with a 
yellowish border. Venter uniformly light greenish-yellow; legs all yellowish; all 
tibie with a double row of rather small blackish spots above. 
Male.—Length, 1.00™™; wing expanse, 2.87™; greatest width of fore wing, 0.53™™, 
Differs from the 9 principally in the antenne. In the ¢ antenne the leaf-like ex- 
pansion of the scape is not so broad, and its white tip and base are more marked; the 
distal half of the pedicel is white, but the rest of the antenne, including flagellar 
joints 5 and 6 and the club, is of a uniform brown thickly clothed with short griseous 
hairs; the club is faintly yellowish at tip; and seen in certain lights, there is a yel-
