hirtus it likewise differs in its very much slighter dorsal 

 pubescence. I am not prepared to say that in its natural 

 state it may not produce some cotton, although none of my 

 specimens has any. 



I find I have omitted to say that the adult male and the 

 male pupa are unknown. 



Lachnodius hirtus, sp. nov. Plate XXII., figs. 1-9. 



Adult female dark-purple, but covered with a quantity of 

 very short white filaments rising from the dorsal hairs, so 

 that the general appearance is grey ; form subglobular ; 

 diameter about lin. or ^in. before gestation. Dorsum covered 

 with great numbers of short but rather strong brown hairs, 

 which give it a woolly appearance. Antennae of seven joints, 

 of which the third is the longest, then the fourth and second, 

 next the first, and the last three are the shortest and equal ; 

 the last joint is not elongated. All the joints bear a few 

 hairs, the last having several. Feet long and strong ; coxa, 

 trochanter, and femur large and thick ; tibia cylindrical, three 

 times as long as the tarsus, and bearing on the inner edge 

 several strong spines and at the tip two spurs ; tarsus short 

 and thick, with two slender spines on the inner edge ; claw 

 short and broad. There are no digitules either on the tarsus 

 or on the claw. The anogenital ring has about twenty hairs. 

 The mentum is large and monomerous. The abdominal ex- 

 tremity is rather truncate, and there are no anal tubercles ; 

 but two of the hairs on the extreme margin are a little longer 

 than the rest. 



Second stage of the female not observed. 



Larva reddish- or yellowish -brown, active, elongated, 

 tapering posteriorly ; length about ^^gin. Abdomen ending 

 in two very minute anal tubercles, each bearing a long seta. 

 Antennae of six rather thick joints, of which the third and the 

 sixth are the longest ; on the last joint are several hairs, of 

 which one is much longer than the rest. Feet long and 

 rather slender ; tibia rather more than half as long as the 

 tarsus ; claw very small and slender. There are four digi- 

 tules, all of which are fine hairs. The dorsum is covered with 

 many fine hairs, and on the margin there is a row of strong 

 spines, of which the two which are between the anal tubercles 

 are double. 



The male pupa is covered by a white cylindrical sac of 

 white cotton, about ^in. long. The enclosed insect has not 

 been observed. 



Adult male unknown. 



Hab. In Australia, on Acacia sp. My specimens are from 

 Mr. Froggatt ; I beheve the locality to be Thornley, near 

 Sydney. As, however, the adult female is quite apt for
