equal except the last, which is large and fusiform. Feet thick 

 and strong : tibia and tarsus equal in length. Anal tubercles 

 very small and inconspicuous, setiferous, with a few spines. 

 Epidermis bearing spinnerets aad spiny hairs, as in the adult. 



Larva and male not observed. 



Hah. In New Zealand, on Fagus ftisca, Eeefton district : 

 specimens from Mr. Eaithby. 



This is a very peculiar species, and in its habit of growth 

 and position departs a good deal from the normal type of 

 Dactijlopius. In its way of standing on its head and filling 

 the space between its body and the tNvig with cotton it imi- 

 tates Icerya, and I have therefore given it the specific name 

 above. It might very easily be mistaken, on superficial ob- 

 servation, for GossyiMria cavcllii, which also lives on Fagus 

 and constructs large cushions of yellowish cotton ; and the 

 similarity is enhanced by the position of the insect — half em- 

 bedded in the cotton, with the dorsal region exposed. But, 

 apart from the much greater size of D. iceryoides, examina- 

 tion of its organs shows at once that it is not an Acantho- 

 coccid. The insect is one of the largest Dactylopidce known 

 to me, and it certainly presents a very striking appearance as 

 viewed in its natural position on a twig.

p. 149. 



Amongst the quantity of Asindiotus destructor mentioned 

 above as sent to me by Mr. Cotes, of Calcutta, on leaves of 

 cocoanut from the Laccadive Islands were a few insects which 

 I consider to be only a variety of D. cocotis, originally de- 

 scribed by me from Fiji. Their colour was yellowish instead 

 of red, and in some cases the antennte exhibited only seven 

 joints. In other respects, especially in the tufted hairs of the 

 epidermis, they agreed with the type, and neither of the two 

 points just mentioned is sufiicient to raise them to specific 

 rank.

figs. 6-8. 



Adult female enclosed in a mass of white, or sometimes 

 greyish, rather loose cotton, wliich, when separate, takes a 

 more or less globular form, but may be aggregated in large 

 masses covering the twigs. Insect subgiobular, flat beneath 

 and convex above ; colour red, or purple, or brown ; distinctly 

 segmented : length sometimes reaching ^in. Antennae of pro- 

 perly eight joints, but sometimes of seven ; the fourth, fifth, 

 sixth, and seventh the shortest, the last the longest and 

 cylindro-fusiform. Mentum rather large, pointed, trimerous. 

 Feet usually normal, sometimes rather short. Anogenital
