angular disk pores, these scattered rather uniformly over the 
body surface; ventrally with these pores distributed uniformly 
except at margin close to and in the “cerarii,” with some 
large circular, multilocular disk pores around the genital 
opening and in narrow transverse rows on the two segments 
anterior to this, with a very few, tiny tubular ducts near the 
genital opening and with much larger, short tubular ducts in 
clusters just within the “eerarii” on the last five or six abdominal 
segments, these ranging from four to eight in number in the 
three clusters anterior to the apical but with only one or rarely 
two in the one or two anterior groups, the apical group median, 
usually with about twelve pores in it; derm dorsally with fairly 
uniformly scattered, very slender, lanceolate setae, ventrally 
with longer, slender hair-like setae; anal ring of normal form, 
with inner and outer rows of pores and with three primary and 
usually four smaller, secondary setae on each half, longest anal 
ring seta about 110g; with a single median quadrate ventral 
cicatrix posterior to the hind legs. 
Immature stages. — None available for examination. 
This species has been described from four mounted and a 
few unmounted specimens collected by Dr. Wheeler with the 
following note: 
“No. 79. Barakara, B. G. July 15, 1920. Taken in a 
large colony of the ant Tranopelta gilva Mayr, under the bark 
of a living tree. The white coccids were present in great numbers 
over the whole surface of the wood. The ant is usually sub- 
terranean, its nest under bark being very exceptional.” 
The types are in the U. S. National Collection of Coccidse. 
In the multiplication of the anal ring setse is found a con- 
dition exactly comparable to that in Pseudococcus rotundus, just 
described, and it is also similar to the structural modifications 
of the anal ring in certain other related forms known to be pro- 
tected and attended by ants, such as Lachnodiella cecropice, 
suggesting the possibility that the relationship between the ant 
and mealybug may have had some influence on the modification 
in structure.
