mentum monomerous. On the ventral surface are many spin- 

 nerets, narrow projecting tubes, which are most numerous at the 

 edges and near the posterior extremity. 



Second stage of female not obsei'ved. 



Larva {g) active ; body elongated, very indistinctly seg- 

 mented; colour brownish-yellow. Abdominal cleft and dorsal 

 lobes present. Tlie lobes are somewhat long, so that some larvae 

 seem almost to liave anal tubercles ; setae long and thick. 

 Antennae (Ji) rather disproportionately large, with six joints, of 

 which the third is the longest, the rest sub-equal ; one or two 

 short hairs on most of the joints, and one the last, which is 

 fusiform, several hairs, of which one is very long, almost equal 

 in leng-th to the w^hole antenna. Feet also large and long, all the 

 joints thick ; the tibia is longer than the tarsus (an exceptional 

 character in a larva) ; digitules, both upper and lower. Knobbed 

 hairs. Anogenital ring (i) wdth eight hairs. A few^ short 

 spines round the edge of the iDody. 



Male in all stages unkno%vn, but on the twig examined, 

 amongst a number of females, there were a few empty, broken, 

 glassy tests, of the usual form of Lecanidae ; these seem un- 

 doubtedly the tests of male pupa?. 



This appears to be clearly a Pulvinaria, and differs in a few 

 particulars from described species. The cottony ovisac is shorter 

 and more ring-shaped than usual in the genus. But the species 

 of Fuhinaria have not been diagnosed with sufficient complete- 

 ness. F..Titis, Linn., P. crrtemisict, Licht., and P. oxyacanthce, 

 Linn., exhibit characters found in the South Australian insect. 



Group — Coccidin.e. 

 subdivision acaxthococcid^. 



Genus — Eriococcus, Targioni- Tozzetti. 



Adult females enclosed in a sac of felted cotton ; body elong- 

 ated, segmented; anal tubercles conspicuous. 



Amongst the characters hitherto ascribed to this genus are an 

 elongation of the sac and a number of spines on the dorsum, and 

 the sac is usually so clearly cotton}^ as to present no difficulties. 

 The insect about to be described is abnormal in both particulars, 

 but other characters seem to place it in this genus — indeed, it 

 agrees with no other — and it is therefore so allocated here. It 

 presents several features of considerable interest.
