pleura distinctly reticulate throughout except on the metapleura; abdomen 
apparently smooth throughout. 
Frontovertex with mostly antrorse short setae arising from the pin- 
punctures, the lower face and cheeks with similar finer setae; eyes with 
numerous but not dense short erect setae; posterior margin of pronotum 
with a row of setae about like those on the scutum; the seriately arranged 
setae of the scutum rather coarser and longer than those on the fronto- 
vertex, the transverse row on posterior margin containing about fourteen, 
and the median longitudinal rows about six or seven setae; scutellum with 
about thirteen pairs of setae on the basal two-thirds, which strongly in- 
crease in size from the base towards the apex; the latter evidently pro- 
vided with another pair of setae, which are broken off in the type, 
although their position is indicated by punctures; propodeum with a small 
tuft of fine short setae on the lateral margins; abdomen with fine setae 
along the sides and more numerous setae at apex. 
General color aeneous black; the head, except most of the face, with 
a rather weak dark bluish-green luster, the pronotum and mesoscutum 
with a similar somewhat more greenish luster; facial impression, axillae, 
seutellum, and abdomen much more lustrous and with green, brassy, and 
dark purplish reflections; tegulae and underparts of thorax shining piceous 
with a metallic luster only on the pro- and metapleura. Seape dark brown, 
the pedicel and flagellum blackish. Legs shining piceous, with the tips of 
the front and middle femora somewhat paler or brownish; trochanters, 
apical third of front tibiae, middle tibiae except about basal third and 
the tarsi, except apical joint of hind pair and apex of last joint of the 
other pairs, brownish yellow. Wings entirely hyaline, the veins brownish 
yellow, with the marginal vein a little darker. Pubescence of body wholly 
dark colored. 
Length of body, 1.36; length of head, 0.417; width of head, 0.443; 
thickness of head fronto-occipitally, 0.259; width of vertex at anterior 
ocellus, 0.160; length of antenna, 0.742; width of mesoscutum, 0.429; 
length of fore-wing, 1.183; width of fore-wing, 0.523 mm. 
Described from one female (holotype), collected in Hono- 
lulu in 1906 by Dr. Perkins. The following note by Dr. Perkins 
is attached to the specimen: “Jn horto meo. Not previously seen 
by me.” The species has not been taken since, and there is, there- 
fore, some doubt that it has become established in the Islands. 
APHELINIDAE. 
Aphelinus maidis n. sp. Fig. 5. 
Female. Head of the usual shape, wider than the thorax, as seen from 
above nearly three times as wide as thick fronto-occipitally, as seen from 
in front much wider than long; frontovertex only a little longer than wide
