possibly normally spine-bearing, two dorsally, two ventrally, two close to margin 
dorsally, and two submarginal ventrally; body terminating in a heavy, short, cylin¬ 
drical protuberance having an irregular transverse opening in its center. 
Adult male (PI. 133, B, C, N-R).—Elongate, slender, sides nearly parallel, 
rounded anteriorly and tapering to a point posteriorly, dimensions from specimens 
mounted alive in balsam, length 0.42 mm., width 0.14 mm.; antennae stout, placed 
close together at anterior apex of body, the two bases separated by perhaps half the 
width of the basal segment, this much broader than long, the second segment stout, 
somewhat larger apically, the third segment with a slender stalklike base, this with 
several grooves and ridges running around it, but the apical three-fifths strongly 
expanded, fourth segment also triangular, but stouter at base than third, remainder 
of antenna, in specimens mounted in balsam while alive, appearing as three distinct 
but closely united segments, this appearance much less conspicuous in specimens 
treated with caustic potash and stained, but still indicated, the antenns, therefore, 
probably 7-segmented with the five terminal ones forming an elongate club terminating 
in a stout button appearing more or less distinctly set off by a joint between it and 
the club proper, as if it might be still another segment; so far as can be determined 
with two long, slender setae on II, III, and IV, with four similar at the apex of the 
club, and with one stout spine on V, one, longer, on VI, and two, still larger, on VII; 
measurements of one antenna in microns as follows: I, 14.2; II, 17.5; III, I4; iy, IO<7 J 
V, 10.4; VI, 7.4; VII, 14.3 (total of club apex 32.1); legs short and stout, tibia and 
tarsus of each bearing one or more large, round, apparently sensory pores; lengths 
mmicronsof outer portion of a middle leg: Femur, 32; tibia, 18; tarsus, 14.3; claw, 10.7; 
digitules about 14; claw with denticle, digitules slender, slightly knobbed at tips! 
eyes simple, only one pair present, these as spots on margin a little posterior to the 
antennae; mouthparts entirely wanting; wings entirely wanting; spiracles small, the 
bar stout, without any accessory pores; derm, so far as can be determined, entirely 
without specialized secreting pores, bearing, however, a number of tiny chitinized 
circles, these occurring singly, but probably in definite arrangement, normally seta- 
bearing; penis elongate, slender, apparently cylindrical, the surface roughened; sheath 
elongate, tapering, pointed, length about 30 microns, width close to base about 7.5 
microns, suddenly expanding at base to about 14 microns. 
In preparation of the preceding description specimens of one or more 
stages of the species from each of the lots of material now in the National 
Collection of Coccidae have been examined.
