152 ASTEROLECANIUM BAMBUS^. 



The empty ovisac is of a pale straw-colour. The 

 fringe of long, pink, glassy rods forms a single com- 

 pact series all round the margin. 



Long, 2-3*50 mm. ; wide, 1-1'25 mm. 



Adult female, after treatment with potash (PL LXII, 

 fig. 6), elongate, narrowed posteriorly. Eudimen- 

 tary antennae (PI. LXII, fig. 9) usually with one 

 long and one short spiny hair. Eostrum (PL LXII, 

 fig. 10) very large, more or less pyriform, and formed 

 of unusually broad bands of chitin ; mentum small 

 and widely rounded at the apex; unexpanded filaments 

 scarcely longer than the mentum. Spiracles rather 

 large, bases broad. Anal extremity (PL LXII, fig. 7) 

 faintly produced ; anal lobes small but distinct, each 

 furnished with a single long hair ; the space between 

 the lobes chitinised, margin with four slight indenta- 

 tions producing four minute tuberculate projections, 

 each bearing a minute spine. Anal orifice with six 

 long hairs, which pass under a slender chitinous band 

 or loop. Marginal compound spinnerets (PL LXII, 

 fig. 8), shaped like the figure 8, form a single series all 

 round the margin, and within them on the dor sum is 

 a single series of small simple spinnerets as in A. 

 variolosum. 



Male apparently unknown in any stage. 



Larva (PL LXII, fig. 11) narrowly elongate. 

 Antenna (PL LXII, fig. 12) of six joints, of which the 

 sixth is much the longest, and equals the third, fourth, 

 and fifth together; formula 6, 1 (2, 3, 4, 5). Legs 

 (PL LXII, fig. 13) rather long, with the tarsi broaden- 

 ing towards the claw ; digitules simple, those of the 

 tarsi very long. Anal lobes rudimentary. Anal orifice 

 with six hairs. Marginal compound spinnerets re- 

 sembling those of the adult female, but much more 

 widely separated. 



Second-stage larva with the tibias and tarsi (PL 

 LXII, fig. 14) much broader than those of the embryo, 

 and the antennae (PL LXII, fig. 15) also shorter and 

 stouter.
