the bare spots on the dofsum is also characteristic. I Icnowof no other species 

 that possesses the conspicuous tubular ducts which, in this insect, take the place 

 of the usual ceriferous tracts. Ripersia filicicola, of Nevvstead, produces some- 

 what similar glassy filaments, but that insect is distinguished by its six-jointed 

 antenna. 



PSEUDOCOCCUS KANDYENSIS, nov. 

 (Plate CL.) 



Adult female oblong oval, tumescent ; median dorsal area elevated, more 

 particularly on the thorax. Colour, dark slaty grey or dull purplish grey ; 

 closely powdered with white mealy secretion. Anal orifice encircled by a pair 

 of opaque white curved waxy plates, and with a pair of short white divergent 

 flattened filaments from the aperture itself. The early adult insect rests on a 

 pad of tangled pale golden silky filaments which extend beyond the margins of 

 the body {fig. i). Later, the insect is partially concealed beneath a covering of 

 loose woolly secretion. Limbs and antennae rather small. Antenna {fig. 3) 

 eight-jointed ; eighthconsiderably the longest ; second next longest ; remainder 

 sub-equal, the fourth usually the shortest. Legs (y?^. 4), stout ; tibio-tarsal 

 section shorter than femur and trochanter ; tarsus short, approximately one- 

 third length of tibia ; claw short and stout, ungual digitules slightly dilated, 

 tarsal digitules simple (see fig. 5). Spiracles {figs. 8, 9), small and slender. 

 Derm with scattered minute circular pores and short inconspicuous hairs ; the 

 marginal area with some larger and more conspicuous broad-rimmed pores 

 communicating with short stout ducts {fig. 6). Anal lobes small and sub- 

 conical (see fig. 7) ; each with two longish slender sharply pointed spines, 

 several longish hairs, and a stout seta of approximately the same length as the 

 setae of the anal ring. There are no spines on any other parts of the body. 

 When boiled in potash the insect exudes a pale pink stain. Length averaging 

 2'5 mm. 



Apparently ovoviviparous. No ovisacs or ova observed, but numerous 

 newly emerged larva;. 



On a small wiry grass, on edge of jungle. Kandy.

 Dactylopiiis pulverariiis., Newstead, Mon. Btit. Cocc, Vol. IL p. 174 (1903). 



Adult female {fig. 2), very elongate, the length being from three to four times 

 greater than the breadth. Colour, pale pink to purplish brown ; more or less 

 completely covered with white powdery secretion. Antennse and limbs small. 

 The antenna is said by Newstead to contain either six, seven, or eight joints, of 

 which the last is considered to be the normal number. In examples from 

 Ceylon the smaller numbers (six and seven) appear to be mote usual {figs. 3,4), 

 the terminal joint is by far the longest, exceeding the united lengths of the two
