52 PULVINAEIA VITTS. 



(PL XLV, fig. la). So much is the body wrinkled 

 at this stage that the dermis has often the appear- 

 ance of being deeply folded. After parturition the 

 colour changes to a uniform pale or dark chestnut- 

 brown, and the dermis is slightly shining. Antennas 

 (PI. XLV, figs. 2-4) normally of eight joints, but 

 there are sometimes only seven (fig. 4). Formula 

 3, 4, 5, 2, 8, 1 (6, 7), or (3, 5), (2, 4), (6, 7), 8, 1. 

 In all the specimens the second joint possesses a 

 very long hair, and there is a slightly shorter one on 

 the fifth joint, and on the terminal one are five or six. 

 Legs ordinary ; digitules to tarsus simple, those of 

 the claw rather strongly dilated. Loop of rostrum 

 scarcely reaching insertion of intermediate legs ; men- 

 turn uniarticulate and small. Dermis (PI. XLV, fig. 5, 

 anal extremity) with numerous ovate or approximately - 

 circular pores, and fine pentagonal tesselations, which 

 usually disappear in boiling caustic potash. Marginal 

 hairs small, slender, and generally curved. Stigmatic 

 channel with minute circular spinnerets ; marginal 

 spines in a group of three, of which the centre one is 

 much the longest and very slightly curved. Anal ring 

 (fig. 56) of eight hairs, enveloped, as in the genus 

 Lecanium, in a thin and finely striate tube (fig. 5), 

 which partly obscures the hairs of the anal ring within. 

 Anal lobes (figs. 5, 6 a) with several fine hairs at the 

 apex. 



The young adult female exactly resembles a Leca- 

 nium. Colour, under a lens, ochreous or dark yellow, 

 rendered almost obscure by more or less confluent black 

 spots ; dorsum with a median ochreous or dull crimson 

 band; to the naked eye the females appear dark 

 smoky-brown in colour, with a faint olivaceous tinge, 

 but the dorsal band is usually distinct. 



Larva (PI. XLIX, fig. 8) with the antennae (PL 

 XLIX, fig. 9) of six joints; formula (3, 6), 2 (1, 4, 5). 

 Legs (PL XLIX, fig. 9) ordinary. Anal ring with six 

 hairs.
