R. NEWSTEAD — NOTES ON SCALE-INSECTS (COCCIDAE). — PART I. 71 



Larva of female. — Ellipsoidal ; anal orifice in the middle of the dorsum, as in 

 the adult female ; upper plate with four immensely long, stiff hairs, and the inner 

 edge fringed with minute hairs ; lower plate with (?) two long stiff hairs ; 

 chitinous ring surrounding the plates, ovoid. Dorsum with four longitudinal 

 rows of long, curved, and laterally serrated spines (fig. 5a) ; marginal spines 

 (fig. 5b) similar, but much longer, and almost straight, with the tips more or less 

 pointed ; alternating between the long serrated spines are some short ones with 

 slightly dilated and obtusely rounded tips. Immediately in front of each antenna 

 is an immensely long, stiff hair, and there are two hairs at the end of the body 

 which are of greater length. Antennae of six subequal segments, terminal

segment with numerous spinose hairs. Mentum large, bimerous ; rostral 

 filaments very long. Legs with a very long stiff bristle-like digit to the tarsus ; 

 digitule of the claw as in the female. 



Larva of male. — Much more elongated than the larva of the female. Dorsum 

 with four equidistant rows of relatively slender, serrated and almost straight 

 spines (fig. 5c) ; marginal spines (fig. 5d) similar, but longer and arranged in 

 pairs ; all the spines both marginal and dorsal are much more widely separated 

 than are the corresponding spines in the larva of the other sex. Buccal orgr/ns 

 obsolete. Anal orifice in the normal position at the distal end of the body. Legs 

 similar to those of the larva of the female. Number of segments in the antennae 

 doubtful.
