that it destroys the Coffee plantations in Ceylon. $ . Clear light 

 pinkish colour, slightly pubescent : head transversely ovate-rotundate, 

 narrowed, and angular in front ; eyes large, black ; ocelli two, small, 

 lateral ; antennae 9- jointed, the second joint smallest, third longest, 

 thence decreasing to the tip. Thorax ample, cordiform, narrowed in 

 front : wings two, hyaline, with two veins, of which the subcostal vein 

 is dark pink, not folded straight down the back when at rest, but half 

 spread out : scutellum ample, transverse, rounded at the apex. Abdomen 

 triangular- sub cylindrical, of shrivelled appearance, with two lateral 

 points, one central appendage, and two long, thin, white filaments at the 

 extremity. 



? . Apterous, tortoise-like, yellowish, marbled with grey or light 

 brown, sub-oval, more or less semi-globose according to age, dorsum 

 with one elevated longitudinal and two transverse ridges, uneven : 

 cleft behind, at the extremity of a split bifid, anal flap or lobe of a brown 

 colour : eyes marginal, black : antennae 7-jointed, the third joint longest : 

 the rostrum with one long sucking bristle. Old individuals are light 

 brown with a dark margin, smooth, semi-globose, fixed to the branch. 



Larva of ? has two anal filaments, which are lost when the insect 

 undergoes the final moult. The larva and pupa in $ and ? are active, 

 except the pupa of the $ , which is plentiful on the underside of the 

 leaves, where the long narrow oval shell under which it rests is easily 

 discovered : this shell is transparent and composed of nine plates of 

 which three are central and three are on either side. Sometimes the 

 entire underside of the leaves is covered with nothing but the pupa of 

 the S all dead. The eggs are oval and of a pinkish colour and are 

 not actually laid by the ? , but when they are matured the parent dies, 

 her whole interior forming one mass of eggs protected by the shell. 

 The above is Metner's description of the form found in Ceylon. Sig- 

 noret describes specimens from Bahia thus : — Brown-red, hemispheri- 

 cal, margins a little flattened : antennae 8-jointed, third joint longest, 

 4 and 5 equal, 8 longer than the two preceding taken together : feet 

 long, tibiae one-third longer than the tarsi, which are articulated : claw 

 very stout, the two lower digitules horn-shaped : anal ring with eight 

 very long hairs, above on the abdomen six hairs, two on each segment 

 at the tip : the stigmatic hairs of the margin very long, very obtuse 

 at the tip and accompanied by two very short ones ; the hairs of the 

 circumference obtuse at the tip, greatest length, 2^ ; broad 1| milliras. 

 This insect is found on coffee, tea, orange. Gardenia^ and many jungle 

 trees. 



The brown scale-insect is also infested by Hymenopterous insects, 

 perhaps more than the white scale insect or the black scale. These
