lobes. Spines, 4 on each side of, and 2 between, the median lobes. Marginal 

 tubular spinnerets 6. Five groups of circumgenital glands, forming an 

 almost complete arch ; the number of orifices seem to vary a great deal, 

 and the formula given here are for two specimens, that on Pittosporum — 

 anterior group 6 orifices ; anterior laterals 24, 19 ; posterior laterals 13, 13 : 

 and that on Astelia — anterior group 13 ; anterior laterals 24, 19 ; pos- 

 terior laterals 14, 15. A few small oval spinnerets are scattered over 

 the pygidium. Anal orifice and vaginal opening opposite, and situated 

 centrally between the grouped glands. Last three free abdominal seg- 

 ments with group of 3 spiny hairs ; cephalic extremity smooth and hair- 

 less. Length, 1-55 mm. 



Hab. — On bark of Pittosporum sp. and on Astelia, at present only from 

 Oamaru. 



This species is very like Lepidosaphes, but, owing to the large second 

 exuvia, must be placed in the genus Pinnaspis. I found on Astelia what 

 is evidently the supposed male puparium, which agrees with Signoret's 

 description ; but, as the insect enclosed was not in the pupa stage, it was 

 impossible to be sure of its true character. 



Note. — The genus Pinnaspis has not hitherto been recorded as occur- 

 ring in New Zealand.

long hairs and 8 short ones. Eostrum short, rostral setae short. Spiracles 

 very thick, and barrel-shaped ; anterior spiracles with several spinnerets 

 immediately above, which, with others, form a band which slopes upwards 

 towards the margin ; posterior spiracles with a scattered group of the same 

 immediately below. Legs small ; coxa short and broad ; trochanter large, 

 and appears fused to the femur, which is short and broad ; tibia narrow, 

 dilated towards the tibio-tarsal joint ; tarsus tapering towards claw, and 

 slightly longer than tibia. Upper digitules long fine knobbed hairs ; lower 

 digitules broad. The coxa on the posterior pair of legs is abnormally
