 (Text Figure 3.) 



Daciylopius comstocki, Kuwana, /"r. Cat. Ac. Set., Vol. III., p. 52 (1902). 

 Pseiidococcus comstocki, Fernald, Cat. Coco, of the World, p. 100 (1903). 



Adult female elongate ovate, dull pale purplish, closely overlaid with vi^hite 

 mealy secretion. Margin with a series of slender waxy tassels, which gradually 

 increase in length towards the posterior extremity of the body. There are 

 seventeen ceriferous tracts on each side of the body, of which the first three or 

 more (occasionally as many as seven) carry three or four spines apiece {fig. 

 3, d) ; the remaining tracts with 2 spines only. The spines of the seventeenth 

 (anal lobe) tract are greatly enlarged {fig. 3, g), and those of the sixteenth, 

 tract are slightly enlarged {fig. 3, /). The seventeenth tract is surrounded 

 by a well-defined ovate, chitinized area, narrowed posteriorly {fig. 3, c). The 

 tibia of the hind limb is slender, and is fully three times the length of the 

 tarsus. There are scattered translucent pores on the outer area of the 

 tibia, on the inner area of the femur, and— a very few — on the outer area 

 of the coxa. Cerarial pores rather scattered (not crowded as in lotigispimis 

 and marittvius). Caudal setai as long as or slightly longer, but more slender 

 than those of the anal ring. Length 2*5 to 3 mm. ; breadth i'5 to 2 mm. 



On Loranthus sp., Trema orienialis, and Cinnamotmim cm/iphora, Punda- 

 luoya. 



Superficially resembling both longispinus and niaritt7)ius ; distinguishable 

 from the former by the shorter lateral tassels, and by the absence of a circum- 

 scribed chitinous area surrounding the penultimate ceriferous tract ; also by 

 the presence of translucent pores on the hind limb. Differs from viariiimus in 

 the absence of a marked dilation of the tarsus of the hind limb, and the 

 smaller number of translucent pores on the same ; in the presence of a circum- 

 scribed chitinous area on the seventeenth ceriferous tract, and in the less 

 crowded condition of the cerarial pores. 



Originally described from Japan, but occurring in the West Indies and 

 Southern States of America, and probably throughout the Indo-Asiatic Region.
