is, 6 Morrison: Nondiaspine Coccidse 673 
ing the rudimentary type; spiracles small, with slender shank 
and expanded ends ; marginal flabellae fan-shaped, large, broadly 
expanded, roughly circular in outline, widest at or a little 
beyond the middle, the edge entire, faintly striate, the striae 
diverging from base; in older individuals the flabellae usually 
distinctly wider than long and widest about the middle, over- 
lapping more or less, this varying from adjacent flabellae only 
slightly, overlapping to alternate flabellae nearly meeting across 
the intervening one; spiracular spines three to a group, stout, 
but not very large, each group set in a distinct chitinized inci- 
sion of the margin, all three approximately equal in size; body 
margin with tiny incisions between the insertions of the fla- 
bellae, usually with jonly a single incision, making two lobules, 
sometimes with two incisions and three lobules, this arrange- 
ment inconspicuous, and sometimes obliterated in the older, 
mature individuals; with an occasional minute dorsal seta at 
least near the margin ; no differentiated ducts or pores, observed 
on the dorsum; ventrally with a single row of quinquelocular 
pores running from each spiracle to its corresponding spines, 
and with some similar, but larger, pores with more loculi around 
the anal plates ; anal plates small, each about 125 y long by 46 y 
wide, set at the apex of a short cleft with contiguous sides; 
each plate sharply angulate anteriorly and posteriorly, the outer 
angle rounded off, widest at or a little behind the middle, the 
posterolateral margin faintly crenulate; perhaps with two very 
minute subapical setse dorsally, apparently with three ventral 
setse and a single fringe seta on each side, all these minute ; with 
two minute dorsal pores on each plate at and posterior to the 
middle; anal ring small, normally placed well anterior to the 
anal plates, the setse longer than the plates, curved and noticeably 
expanded at base, six in number. 
Larva . — Elongate oval, about 0.63 millimeter long by 0-32 
wide ; antennae 6-segmented, fairly well developed, average 
measurements as follows (in microns) : I, 14; II, 13.5; III, 35.7 ; 
IV, 21.4; V, 17.8; VI, 35.7; legs fairly well developed; the 
lengths of a middle leg, coxa, 29 y; trochanter and femur, 64 y; 
tibia, 35 y ; tarsus, 32 y ; tibiotarsal articulation indistinct ; 
marginal setae slender, hairlike, in no way resembling the fla- 
bellae of the adult ; ; spiracular spines set in a chitinous incision 
of the margin, three in number, the intermediate the largest; 
anal plates elongate, slender, rounded anteriorly, sharply pointed 
posteriorly, about 50 y long, with an apical seta about 46 y long.
