E. T. Atkinson — New Species and Oen?i.i of Ooccidre. [No. 1, 



been given to show its connection with the lecanid genns Vulvinaria. 

 The insect is really a hemicocoid possessing more lecanid appearances 

 than any other of the groujo hitherto known. The position of the insect 

 on the tree during its several stages is rather curious. The larvse and 

 the females of the second stage cluster along the midrib of the lower 

 surface of the leaf, whilst the adult female alone is found along the twig 

 to which the leaves are attached (Fig. 1). The secretion is closer than 

 ia Fulvinaria, and quite as cottony during the larval stage, but, in the 

 second stage, becomes more waxy, so as to approach in appeai'ance the 

 genus Orthesia, and the masses of wax on the leaves are more like 

 detached or attached plates (Fig. 2) than threads. Unfortunately the 

 male has not yet been secured. 



It is satisfactory to know that the adult female is subject to the 

 attacks of several species of hymenopterous and dijDterous parasites, 

 which we may hope to characterise hereafter, for, otherwise, from the 

 size and number of these coocids on the leaves and twigs affected, much 

 damage must ensue, should they increase to any extent. It disappears 

 during the rains (July — September), but comes on abundantly at the 

 close of the rains, and matures about April. 



Genus Pskudopulvinaeia nor. 



Adult females naked, without a waxy fringe, somewhat circular or 

 oval and flatfish. In Eermes, the adult female is entirely globular, 

 except a small incision where it rests on the twig to which it is attached, 

 and appears to have neither legs, antennee, nor rostrum. 



PSEDDOPULVINAUIA SIKKIMENSIS, n. sp. 



Adult 2 , above reddish-brown, naked, somewhat convex, irregularlv 

 circular or oval in shape, varying in size, skin smooth, punotulate. The 

 mseot frequently falls off, leaving the white cottony ovisac attached 

 to the twig. Furnished beneath with eyes, antennsB, legs and rostrum • 

 the abdominal cleft and lobes distinct (Fig. 5) : antennas borne on a 

 tubei'cle, C-jointed, second joint longest, unarmed ; others with setre 

 varying in length (Fig. 0) : claw with four digitulcs, the upper pair 

 longest (Fig. 7). The ovisac on which the female rests is formed of a 

 compact white cerous substance, following and extending beyond the 

 outline of the insect itself. The spinnerets (filieres : Fig. 8) are 

 scattered irregularly over the nether caudal surface and are not arranged 

 in groups or circles. Found only on the twigs : long, 5 — 9 mill. 



The 9 of the second stage (Fig. 9) with its waxy plates is found on 

 the lower surface of the midrib of the leaf. These plates seem to be
