EARLY STAGES. "Eggs and young larvae brownish red." (Green). 



SCALE OF FEMALE. Plate i, Fig. i. Length, 2.4 2.3 mm. 

 Elongated, broadened posteriorly, the anterior portion often quite 

 narrow ; grayish white in color. Exuviae .8 .6 mm. long, brown in 

 color. 



FEMALE. Segmentation very distinct toward the posterior end of 

 the body. Median lobes (Plate 9, Fig. 10) very large and conspicu- 

 ous ; crenate on their outer edges, the crenations gradually decreas- 

 ing in size from the inner edge of each lobe outward. Second and 

 third pairs of lobes absent. Gland-spines arranged as follows: i, i, 

 i, 1-2, 5-6. The one nearest the median lobes small and obscure. 

 The marginal gland-orifice next to the median lobes is on a broad 

 and conspicuous protuberance. The dorsal gland-orifices are few in 

 number. Second row absent ; third and fourth rows represented 

 only by their posterior groups numbering 2 3 and 2 6 respect- 

 ively. Median group of circumgenital gland-orifices, 17 29 ; anterior 

 laterals, 26 40 ; posterior laterals, 22 35. 



SCALE OF MALE. Plate i, Fig. i A. Length, 1.3 mm. Very 

 distinctly tricarinate. Exuvia pale brownish-yellow. 



MALE. " Adult male bright brick-red. Form normal. Antennae 

 with a single knobbed hair at extremity. Foot, with one tarsal and 

 one ungual digitule. Tarsus nearly as long as tibia. Length rather 

 more than i mm." (Green). 



REMARKS. 



Found in Ceylon on Mitssaenda frondosa and occasionally on 

 Loranthus and Debregaesia. The male scales occur crowded 

 together in groups, each individual being attached to the bark only 

 at the anterior extremity, the rest of the scale being elevated and 

 lying on the backs of the scales next behind it. 



Mr. Green states that the female insect is frequently parasitized by 

 the minute hymenopteron, Aphelinus diaspidis How.
