amply distinct. It is remarkable for its large size and the 

 Y markings. 



(6) Orlhezia insignis^ Dougl , var. 



Vera Cruz. 



The specimens differ a little from tliose found in Jamaica, 

 but there is nothing to separate them speciftcallj from 

 insignis. 



(7) Pulvinaria lutea, sp. n. 



Vera Cruz, on variegated Croton. 



? (adult). On underside of leaves. Sacs about 10 mil! ini. 

 long and 4 broad, convex but depressed, of satiny texture, 

 with nearly parallel sides. Colour bright lemon-yellow. The 

 brown shrivelled female is largely overlapped by the ovisac, 

 which is here plicate, with a tendency to be trifid. 



Substance of body (in caustic soda) yellow; margin with 

 large, distinct, and numerous spines. Derm with numerous 

 tubular glands. 



Legs reddish. Femur about one third longer than tibia ; 

 tarsus a little more than one third length of tibia. Claw short 

 and curved. Trochanter with two equal strong bristles. 

 Femur with a very stout large bristle at right angles to its 

 surface, before its middle. In one specimen this bristle was 

 observed to be accompanied by a smaller similar one. Tibia 

 with a few hairs and a long bristle at right angles to its 

 surface at the distal end. Three strong oblique bristles spring 

 from the side of the tarsus. The tarsal knobbed hairs are 

 very long and stout and distinctly knobbed. The digitules 

 of the claw are immense, with very stout stalks, and broad 

 large flattened knobs. Both digitules and tarsal hairs must 

 be deciduous, as the first leg I examined showed none. 



Egg oval, reddish (in soda). 



Young larva has the claw^ longer and practically straight, 

 with the usual digitules and knobbed hairs. Hind end trun- 

 cate, with a cleft in the manner of Lecaniuin, and a short 

 bristle arising from each side of the cleft. 



The young exhibit the usual characters of the group — the 

 anal cleft, the four lateral incisions, &c. The spines in the 

 lateral incisions are short. The hairs along the margin are 

 short, not very numerous, and show a tendency to be knobbed. 

 The posterior clett is open, and two bristles project from its 

 centre. The shape of the young is elongate, with nearly 

 parallel sides. Colour pale brown or whitish. The eyes, 

 situated on the margin, are reddish brown. The dorsum is 

 bluntly keeled.
