Maskell. — On Coccidae. 53 



Test of male pupa white, more glassy than that of the female : 

 the form is elongated-elliptical, the sides nearly parallel, the 

 dorsum convex : the central region is formed of three plates, of 

 which the two anterior are quadrangular with indented edges, 

 and the posterior one triangular ; surrounding these is a ring 

 of rather large quadrangular plates, on the outer edges of 

 which is a small fringe as in the female. Length of male test 

 about xoin. 



Adult female dark-brown. In the earlier state it is flattish, 

 but at gestation becomes convex with a flattened margin. The 

 form is broadly elliptical ; length when fully developed about 

 iin. Antennae of six joints : the first short, the second much 

 the longest, with a " false joint " at about two-thirds its 

 length, the third and fourth the shortest and equal, the fifth 

 and sixth rather slender and equal : the second and third 

 joints bear three or four hairs, the sixth has several. Feet 

 rather long : the tarsus is about half as long as the tibia, and 

 is somewhat thicker, having a rather swollen appearance : 

 claw moderate ; the digitules are slender : on the trochanter 

 is a long hair, and on the inner edge of the tibia a few fine 

 short sj^ines. Abdominal cleft and lobes moderate. Eos- 

 trum small ; mentum monomerous. On the margin, near the 

 four thoracic spiracles, are four semicircular indentations 

 formed by chitinous bands, each bearing three cylindrical 

 spines. All round the margin is a row of numerous fine 

 longish hairs. There do not seem to be any dorsal spin- 

 nerets. 



Female of the 'second stage covered by a thin white waxy 

 test of irregular segments, which are very brittle and fre- 

 quently almost all broken off, so that the insect in this stage 

 seems almost naked : the fringe is very small. Form elon- 

 gate, regularly elliptical, the margin not wavy ; length about 

 j-Lin. Antennae of six joints. Feet slender, the tarsus some- 

 what swollen as in the adult. Margin bearing numerous 

 hairs ; but in the spiracular indentations there is only one 

 spine. Abdominal cleft and lobes normal. 



Larva yellowish-brown, flattish, active, broadly elliptical. 

 Length about /gin. Antennae of six subequal joints, of whbh 

 the last is the longest : this last joint is irregular and taper- 

 ing to a slender tip, and bears several longish hairs. Feet 

 with a slightly swollen tarsus : all the digitules are fine hairs. 

 On the margin of the body are numerous hairs, of which the 

 last six on each side of the abdominal cleft are much the 

 longest. The abdominal lobes bear long setae. 



Adult male red in colour or sometimes brown. Length, 

 including spike, about T V m - 1 ne wings are iridescent, and the 

 nervure deep-red. Antennae rather long, with ten long slender 

 joints, each bearing numerous hairs. Feet slender. The ab-
