with somewhat more numerous and larger, but scattered setae, 
and with a few pairs, still larger, anterior to anal plates and 
near antennae, anal plates triangular, the anterolateral margin 
more or less distinctly longer than the posterolateral, the angles, 
especially the outer, rounded; dorsally with eight to ten com- 
paratively large, stout setae, scattered through the posterior two- 
thirds of each plate ; with a single larger ventral ridge seta and 
two pairs of fringe setae, the outer of these larger ; anal ring with 
pores and six setae. 
No other stage has been available for examination. 
This species has been described from ten mounted adults 
having the following information: “In hollow stems of Maca- 
ranga triloba, Penang Id. (7. H. Burkill 2693a)” (holotype and 
paratypes) and “in hollow stems of Macaranga,” Singapore (7. 
H. Burkill 1318) (paratypes). Certain differences in these two 
lots of material, notably a little greater length to the dorsal anal 
plate setse and the middle spiracular spines of each group, have 
been noted, but nothing that I can consider as sufficient to jus- 
tify even varietal segregation. The types are in the United 
States National collection of Coccidae. 
The salient characters of the species are indicated in the key 
following this series of descriptions of new species. 
Coccus macarangae sp. nov. Plate 1, fig. 5. 
Adult female. — Short oval, pale reddish brown, darker in mid- 
dle, flat, with faint radiating ridges near margin ; dorsal surface 
appearing naked, possibly with a very thin film of secretion; 
maximum length, 3.25 millimeters; width, 2.25; size and shape 
when mounted similar; derm clearing almost completely, but 
retaining indistinct traces of an areolation similar to that de- 
veloped in C. penangensis, especially around the margin and 
anteriorly; antennae normally 8-segmented, the measurements 
of the single entire example available for examination as follows 
(in microns) : II, 36; III, 36; IV, 21.5; V, 34; VI, 18; VII, 21.5; 
VIII, 33; legs normal but small, the digitules slender, knobbed, 
one of tarsus somewhat larger than the other; spiracles not 
unusual; derm dorsally with a rather conspicuous but irregular 
cluster of relatively large, circular, simple pores anterior to 
anal plates; elsewhere over the dorsum with numerous and 
rather uniformly scattered tiny circular pores, the openings of 
minute tubular ducts; ventrally near margin with long tubular 
ducts with cup-shaped inner ends, these also unusually small,
