Yet auother character is ascribed to Leachia by Sigaoret^. 

 " Male presenting at the extremity of the abdomen tubercular 

 lobes; " and in his descriptions of L. hraziliensis andL. fusci- 

 pennis he mentions these lobes as bearing "bundles of hairs." 

 It Vk'ill be seen that our insect presents also tliis character, and 

 thus all the more clearly belongs to this genus. 



Leachia zealandica, sp. nov. Plate VI., figs. 1-17. 



Adult female red or reddish-brown in colour, excreting 

 Avhite meal and cotton, and also some longish, curling, rather 

 coarse, yellow threads. At the abdominal extremity usually 

 there are two pencils of white cotton, and somewhat thicker 

 quantity of meal ; also often on the last segments short white 

 cottony lateral tassels, as in some DactylopidcB. Body elon- 

 gated, distinctly segmented, elliptical, convex above ; length 

 varying — some specimens reach -Jin., but most are smaller. 

 Eostrum and mentum very large and long : mentum trimerous, 

 with several hairs at the tip. Antennae of moderate length,, 

 not conical, with eleven cylindrical joints, of which nine are 

 sub-equal, the fourth and fifth being a good deal shorter than 

 the rest ; the last joint is fusiform. All the joints bear several 

 hairs, and at the tip of the last there are two strong spiny 

 hairs curving inwards towards each other. Feet rather strong ; 

 tibia not quite as long as the tarsus ; all the joints are hairy, 

 the hahs on the inner margins stronger than the rest ; on the 

 trochanter is a long seta, and on the end of the tibia a strong 

 spine. The claw has a minute tooth on the inner edge ; there 

 are no tarsal digitules ; at the base of the claw is a sub-conical 

 process with a single rather long digitule with dilated end. 

 The anogenital ring is large, and (unusual in the group) bears 

 elongate pores and several hahs, of which six are much larger 

 than the rest : these hairs bear the pencils of cotton noticed 

 above. Around the ring is a patch containing numbers of cir- 

 cular spinneret-orifices. Epidermis covered with numerous 

 hairs, some pretty long, some small and spiny, interspersed 

 with chcular spinnerets : the longer hairs frequently form 

 tufts. 



Larva yellowish-red, covered with white meal ; active, 

 elongated, segmented ; length about 4^m. Two thick pencils 

 of cotton at the abdominal extremity, and on the last three or 

 four segments are lateral tassels of cotton as in Dactylopius. 

 Antennae of seven joints— the first and second equal, the thhd 

 and fourth very short, the fifth and sixth longer but less than 

 the two first, the last large, fusiform, pointed, and half as long 

 as all the rest together ; all the joints hairy, and on the 

 last are two curved spines as in the adult. Feet rather thick ; 

 tibia shorter than the tarsus ; claw toothed, and with a process 

 and digitule as in the adult. Eostrum and mentum large ;
