Prospalta murtfeldtii Howard (fig. 12), 
Prospalta murtfeldtii Howard. Insect Life, vol. yii, p. t>, 1894. 
Female. — Length, 0.69 linn. ; expanse, 1.7 mm.; greatest width of fore- 
wing, 0.3 mm. Joint 1 of funicle wider than pedicel; nagellum gradu- 
ally widening from base of pedicel to base of club. Surface of body 
nearly smooth; scutelluni slightly shagreened. General color light 
yellow; mesoscutum with brownish patch covering entire disk; nieso- 
scutellum with two large brown patches, one each side of middle line; 
axillae each with a brown patch; metanotum brownish; base of abdo- 
men brown; tip of abdomen also brown; antenna 1 brown, with the 
exception of joints 2 and 3 of the funicle, which are whitish; all eoxre 
and femora light honey-yellow, except that hind femora are dusky 
at base; front tibia 1 with a dusky ring near middle; first and second 
tarsal joints of forelegs dusky; middle 1 and hind tibia 1 each with two 
dusky bands: first tarsal joint of middle and hind legs dusky; wings 
hyaline witli a fuscous basal patch, and a triangular median fuscous 
patch with its apex at stigmal vein and its base reaching somewhat 
less than half of outer hind margin; entire disk of wing densely, finely, 
and uniformly ciliate; apical spur of tibia 1 rather short. Hind-wings 
with two rows of discal cilia and an interrupted third row on outer 
third. Hind marginal cilia somewhat longer than wing width. 
Described from five balsam-mounted female specimens reared by Miss 
Mary B. Murtfeldt, at Kirkwood, Mo., from Aspidiotus uvce. deceived 
November 4, 1888. 
Since the original description was published I have received a series 
of thirteen specimens of this insect from Mr. W. G. Johnson, of the 
State Laboratory of Natural History, at Champaign, 111. Eleven of this 
series Mr. Johnson reared from a new species of Aspidiotus on cherry- 
twigs, and the other two from a new species of Aspidiotus on currant 
canes, both at Champaign, 111. The specimens received from Mr. John- 
son were all mounted dry, on tags, while the type specimens from 
Miss Murtfeldt were mounted in balsam. It becomes apparent that 
Miss Murtfeldt' s specimens must have been mounted very soon after 
they issued from the host insect. The colors are lighter, in general, 
than those of the matured and dried specimens. The second funicle 
joint of the antenme is dusky, like the first funicle joint, and not white, 
like the third. The general color of the thorax, instead of being yel- 
low, is dark brown. The basal joints of the abdomen are yellowish, 
with the tip brown. The obvious conclusion is that all these parasites 
should be allowed to mature in color before being mounted in balsam.
