puparium; the poorly developed male pupa surrounded by the 
larval skin, but whether this condition continues through the 
entire pupal period cannot be stated; the male larval structure 
appears intermediate between the young larva and the oldest 
female form as already described; legs and antennae much re- 
duced; anal plates elongate, slender, with about seven or eight 
dorsal pores, possibly bearing setae, scattered through the whole 
length of the plate ; apical seta broken ; with two relatively large 
fringe setae on each side; with three spiracular spines of equal 
length in each group; marginal spine arrangement much as in 
young larva ; multilocular disk pores observed only between spi- 
racles and margin ; cup-shaped tubular ducts numerous, especially 
along the margin and, in transverse groups, on each side ante- 
rior to the anal plates ; the short developing legs and antennae of 
the male pupa about twice as large as those of the larva; the 
pupa not sufficiently developed to show any characters for de- 
scription. 
This species has been described from five females mounted on 
a slide, five young larvae mounted on a slide, two male larvae and 
pupae mounted on a slide, and a number of specimens attached 
to the host. The specimens were found on Alsodeia echinocarpa, 
Botanic Gardens, Singapore, August, 1917 ( Baker 8935) and 
were covered by a carton and attended by ants. The types are 
in the United States National collection of Coccidae. 
I have described this material as representing a new genus 
and species with great hesitancy, as there is considerable evi- 
dence to indicate that the species may be founded on the imma- 
ture female. There is no evidence of the development of the 
ovaries in any of the specimens examined, the difference in size of 
young larva and the largest female found is much less than might 
be expected normally, and the male puparia are much larger in 
proportion to the size of the largest female than is usual in the 
subfamily. In spite of this, however, the differences noted, par- 
ticularly with reference to the anal plates and the marginal 
region, are such as to indicate a considerable divergence from the 
typical condition in the subfamily; and, assuming that the fe- 
males described are only second or preadult stage, any further 
modifications of structure in the adult might reasonably be ex- 
pected to follow along the lines shown by the form described.

With the possible exception of the first, the species that are 
placed in this genus in this paper are a decided puzzle in respect
