Eriococcus tepperi, sp. nov. Crawford Coll. Plate V., 

 figs. 15-17. 



Sac of female dirty-white or yellowish, elongated, elliptical, 

 often aggregated in masses : length about xV^- 



Sac of male similar, but rather smaller. 



Adult female dark-red or brown, shrivelling at gestation : 

 length about Jgii^- • subglobular. Anal tubercles conspicuous. 

 Antennae of six joints, the first three subequal (the third a 

 little the longest), and each about twice as long as the fourth 

 and fifth, the sixth rather shorter than the third, and bearing 

 some hairs. Feet rather slender : tarsus nearly twice as long 

 as the tibia. Anogenital ring with eight hairs. Mentum 

 dimerous. No marginal spines, but on each segment is a 

 transverse row of rather slender spines. Epidermis bearing 

 numbers of small, simple, circular spinneret-orifices. 



Larva red, flatfish, elliptical, active : length about -^jiii. 

 Anal tubercles conspicuous, setiferous. Antennas as in the 

 adult. On the margin a row of slender spines, and a trans- 

 verse row of similar spines on each segment. 



Adult male dark-red, wungs iridescent. Length about ^\fin. 

 Antennae and feet normal. Spike short, conical : the cottony 

 " tails " are very long. 



Hab. In Australia, on Eucalyi)tus globulus and Bursaria 

 spinosa. 



This is another of the late Mr. Crawford's species, and was 

 named by him after Mr. J. G. 0. Tepper, of Adelaide. The 

 species is allied to the New Zealand E. pallidus, but is rather 

 smaller, and differs also in the form of the antenna, the third 

 joint being only very little longer than the second, whereas in 

 E. pallicUis it is a good deal longer. 



Genus Ehizococcus, Signoret. 

 Khizococcus grandis, sp. nov. Plate VI., figs. 1, 2. 



Adult female dark-red, naked, subglobular or subelliptical, 

 convex, distinctly segmented : length about -|^in. Anal tubercles 

 small, and usually hidden by the convexity of the abdomen. 

 Antennae of six joints, of which the second is the longest, the 

 first third and sixth shorter and subequal, the fourth and 

 fifth the shortest : on the sixth are several short hairs. Foot 

 rather slender : tarsus longer than the tibia ; at the extremity 

 of the tibia a spine ; upper digitules fine hairs, lower pair 

 slightly dilated. Mentum dimerous. Anal ring with eight 

 hairs. On the dorsum are some scattered slender spines. 



Larva red, flattish, active : length about -^-^va. Antennas, 

 foot, and tubercles normal. Pound the margin runs a row of 

 rather long and slender spines, and on the dorsum are two 

 longitudinal median rows of smaller spines.
