with abundant cotton. I turned them out into a deep watch- 

 glass and brushed the cotton away. After a few days they 

 surrounded themselves with another thick mass, in which they 

 are now entirely hidden. 



Dactylopius aurilanatus, sp. nov. Plate VIII., figs. 7-18. 



Adult female slightly elongated, nearly globular ; of a 

 rich dark-purple colour, bearing on the dorsum a longitudinal 

 band of bright golden-coloured meal, with small patches of 

 similar meal often visible at the edges. In alcohol or potash 

 it produces a rich-purple tint, and if crushed in the fingers 

 stains them dark-red. The eggs, which are also purple, are 

 laid in a mass behind the insect, in a thin wdiite cottony web, 

 the mass having thus a general dark-grey appearance. Body 

 obscurely segmented. Length about xV^n. Antennae usually 

 of eight joints, often of seven ; in the former case the fourth, in 

 the latter the third, joint is the longest, the rest subequal, 

 except the last, which is fusiform, and nearly equal to the 

 longest : all the joints have a few hairs, the last bearing 

 several. Feet normal, not very slender ; upper digitules long 

 fine knobbed hairs, lower pair slender with dilated ends. 

 Anal tubercles very inconspicuous, each bearing one long seta 

 and a few very short hairs. Anogenital ring compound, with 

 six hairs. Spinnerets not numerous, chiefly situated on the 

 median dorsal region ; mostly simple circular orifices, with 

 some short fine spiny tubes amongst them. On the cephalic 

 region are a few short hairs. 



Female of second stage rich-purple in colour, bearing longi- 

 tudinal rows of golden-coloured meal in detached patches : at 

 the commencement of this stage, however, the meal is nearly 

 white. The rows are arranged as follows : one along the 

 middle of the dorsum, one along each edge, and two others 

 intermediate ; five in all. The meal is in detached lumps or 

 masses, which permit the purple body to be seen between 

 them, giving a tessellated appearance to the insect. Body 

 obscurely segmented ; convex above ; outline elliptical ; length 

 about ^V^- Anal tubercles inconspicuous, each bearing a seta, 

 the meal on which protrudes farther than in the other patches ; 

 between them the hairs of the anogenital ring are usually 

 coagulated in a pencil of white cotton. Anogenital ring with 

 six hairs. Antennae of seven joints, all hairy, the last bearing 

 several hairs and two short terminal spines. Feet as in the 

 adult. Spinnerets fairly numerous, all of them simple circular 

 orifices. 



Larva dull-purple, covered with thin white meal ; flattish ; 

 elliptical; very active; length about -^oin. Mentum rather 

 large, dimerous. Anal tubercles conspicuous. Antennae of 

 six joints, the last fusiform, a good deal the longest, and bear-
