Maskell. — On CoccidaB. 401 



of which the third is much the longest, the fourth the next, 

 then the second and first which are subequal, the fifth, sixth, 

 and seventh the shortest and subequal, the seventh probably 

 the shortest of all. Each joint bears some short fine hairs ; 

 the first has also one and the second two much longer and 

 thicker. Feet rather strong ; the coxa, trochanter, and femur 

 rather thick ; the tibia about twice as long as the tarsus ; 

 both tibia and tarsus are much wrinkled, and the tarsus is 

 curved; claw moderate; all the four digitules are fine hairs. 

 There are several short spiny hairs on each joint of the foot, 

 and on the trochanter are two very long and thick. Eostrum 

 small ; mentum monomerous, subcircular ; setae very short. 

 The abdomen terminates in a curve without any appearance 

 of anal tubercles, nor are there any special terminal hairs. 

 Anal ring large, compound, bearing from twenty to twenty- 

 four long strong hairs. The margin of the body has a series 

 of long and strong spines set closely together ; each spine 

 springs from a projecting tubular base, which is ringed. Epi- 

 dermis bearing many short fine hairs, and near the cephahc 

 and abdominal extremities are tvi^o curved series of stronger 

 spiny hairs, about sixty in each. On the abdominal segments 

 there are great numbers of very minute subcircular marks 

 which seem hke the orifices of spinnerets, but of the twenty- 

 five specimens observed none exhibited either cotton or wax. 

 In some specimens there are two strong short conical spines 

 set close together between the antennae, but these are appa- 

 rently not constant. 



Female of the second stage yellow or yellowish - brown, 

 elliptical, convex, segmented; length about -Jin. Antennae 

 of six joints, which are proportionately thicker than in the 

 adult ; of these the third is much the longest. Feet, mar- 

 ginal spines, and anal ring as in the adult ; but instead of one 

 pair of strong conical spines there are many such pairs — 

 apparently twenty-four in all. 



Larva yellow, subcircular or broadly elliptical, slightly 

 tapering posteriorly ; length about g^in. Antennae short, 

 thick, with six subequal joints. Margni bearing a series of 

 strong conical spines set closely together ; these are propor- 

 tionately shorter than those of the adult, but their points are 

 produced into very long fine threads forming a delicate 

 fringe. 



Hah. In Austraha, on Eucalyptus rostrata. Mr. French 

 has sent me a number of specimens, and says, " It does 

 great damage to young trees at Mooroopna, Goulburn Eiver, 

 Victoria." 



L. lectularius may be distinguished from both the preced- 

 ing and the following species by the much longer marginal 

 spines both in the adult and the larval stages. From L.
