384 Dactylopiince. 



On Jasminum and Lantana (Pundaluoya) ; on cultivated ferns (Colombo) ; 

 on Mimosa (Peradeniya) ; on Gossypium (Kurunegalla) ; and on Albiszia 

 (Kegalla). An almost cosmopolitan species, but confined to glass-houses in 

 the temperate regions. 



When disturbed, the female insect discharges a drop of thick yellowish fluid 

 from the anterior glandular fovete. 



In the synonymy I have purposely omitted early references to the name 

 Coccus adoiuduin, about the identity of which there is considerable doubt. 

 Cockerel! points out that Linnteus's description apparently refers to some 

 Monophlebid species. Signoret's adoniduvi is certainly identical with longi- 

 spitms of Targioni-Tozzetti. It is not clear why Westwood's description of 

 this species, under the name of Pseudecoccus adonidum, in 1839, should not 

 have priority ; but as the insect is now generally recognised as Pseiidococcics 

 longispinKS it seems advisable to retain that name.

Adult female greyish or dull pink, the dorsum closely covered with white 

 mealy secretion. Form long ovate, length approximately twice the breadth. 

 Margin with seventeen equidistant, slender, straight, waxy tassels on each side, 

 short on the anterior parts, and progressively longer towards the posterior 

 extremity of the body, the posterior (caudal) pair of tassels twice as long as 

 the preceding pair, and more than half the length of the actual body of ihe 

 insect (see fig. 2, a). Antenna {fig. 2, b) eight-jointed ; third and eight joints 

 longest, subequal. Legs moderately long and slender ; tarsus approximately 

 one third as long as the tibia ; tibiae of hind limbs usually dilated {fig. 2, k,), 

 its outer area crowded with minute translucent pores ; similar but more 

 scattered pores occur on the inner area of the femur of the same limb. There 

 are seventeen ceriferous tracts on each side of the body ; the first three tracts 

 having three spines apiece, the remainder with two spines only. The spines of 

 the first fifteen tracts are small ( fig. 2, e) and of approximately equal size ; 

 those of the sixteenth tract are larger, while those of the seventeenth (anal 

 lobe) tract are larger still {fig. 2, f). The relative sizes of these spines may 

 be perceived by a comparison of the sockets from which they spring (see fig. 

 2^g, h, z, and 7). There is a diffuse chitinous area, narrowed anteriorly, on the 

 venter of each anal lobe {fig. 2, d). Caudal (anal lobe) setae distinctly shorter 

 and more slender than those of the anal ring. Length (exclusive of waxy 

 appendages) 2*5 to 3 mm. ; breadth averaging i"5 mm. 



On Passiflora sp. and Tomato plants ; Pundaluoya. Until recently 

 recorded from the United States of America only, but now recognised as a 

 greenhouse pest in England. The species probably occurs throughout the 

 tropical and subtropical regions where, owing to its similarity to longispiniis, its 

 identity may have been overlooked.
