30. (2) Aphycus ceroplastis, n. sp. 
Female. — Length, 1.4 mm ; expanse, ^.i)" 11 " ; greatest width of fore wing, 0.51' um . 
Antenna! scape with a slight expansion below near tip; club flattened, oval. Me- 
80scutellum with a slight longitudiual 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 ; fnnicle brownish at joint h 
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 axilhe yellow, with 
a dusky shade towards the pronotal border of the mesoscutum; mesoscutellum black, 
metanotum also black ; tegulae yellow, dusky at tip ; abdomen black above, yellowish 
beneath, especially near base: ovipositor yellow : the conspicuous 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, 1.04 mm ; expanse, 2.4 11 "" : greatest width of fore Wings, 0.42 mm . 
Flagellura of antennae of a uniform light brown; brown spots on cheeks lacking; 
mesoscutum and axillae black : hairs on the abdominal spiracles very conspicuous. 
Variety a. — In four J's the marked appearance of the mesonotum, produced by the 
contrast of the yellow mesoscnturn and axilla- with the black mesoscutellum and pro- 
notum, was lost by a black shade in the middle of the mesoscutum, and the axillae 
were black as in the g . 
Described from 8 9 's, 2 6* 's, and 4 9's of variety a ; all bred from 
scales of Ceroplastes artemesice Riley MSS., collected in 1879, on Arte- 
mesia, at Silver City, N. Mex., by H. H. Eusby. The parasites issued 
in tbe latter part of March. [0. V. R. Coll.] 
31. (3) Aphycus maculipes, n. sp. 
Female. — Length. 1.4 mm : wing expanse, :5.00"" n ; greatest width of fore wing, 0.58 rani . 
In all respects, except in size and details of coloration, similar t> Aph. pule hi arias, 
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- 
tion of the tip. Joiuts 1. 2, 3, and 4 of the fnnicle black, the inner surface of 4 sometimes 
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. Tegulae whitish, dusky at 
t ip. Mesonotum ferruginous; metanotum dusky. Abdomen blackish above, with a 
yellowish border. Venter uniformly light greenish-yellow; legs all yellowish; all 
tibiae with a double row of rather small blackish spots above. 
Male. — Length, 1.00 nim ; wing expanse, 2.8 mm ; greatest width of fore wing, 0.53 mxn . 
Differs from the $ principally in the antenna. In the $ antenna? 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 antenna^ 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-
