Parlatoria pbrgandii, Comst., var. mytilaspiformis, Green. 

 Parlatoria pergandii, Comstock, Rep. U. S. Dep. Ag. 1880, p. 327. 

 Parlatoria mytilaspiformis, Green, Coco. Ceyl., pt. ii, p. 164. 

 I now agree with Dr. Leonardi that this insect is merely an extremely 

 elongate form of pergandii — a species which differs from P. proteus 

 principally in the possession of a small sharply conical fourth lobe on each 

 side of the pygidium, separated from the third lobe by three fimbriate 

 squaraes. This fourth lobe is replaced — in proteus — by a fimbriate process. 

 In var. mytilaspiformis, the fourth lobe is minute and inconspicuous. 

 In typical pergandii it is somewhat larger. 

 Parlatoria pergandii, var. phyllanthi, n. var. (PI. J, fig. 27). 

 Differs from type in the coloration of the 9 puparium (fig. 27), 

 the secretionary area of which is pale transparent ochreous, and the 

 pellicles bright castaneous or brownish orange, each with a broad black 

 median fascia. Length 1*50 mm. 



$ Puparium with the fascia on pellicle greenish. Length 1 mm. 

 Adult $ broadly oval. Pygidium as in type : fourth lobe small, 

 about one-quarter the size of the other lobes. Length O60 mm. 

 Adult $ not observed. 



On leaves of Phyllanthus myrtifolius. Peradeniya. May. 

 Parlatoria (Websteriella) atalantle, n. sp. (PI. J, fig. 28). 

 $ Puparium pale yellow : occupied almost completely by the large 

 nymphal pellicle, with a very narrow fringe of whitish secretion. Flat- 

 fish : oval, the larval pellicle slightly projecting in front. Posterior 

 parts depressed, with an indistinct median carina. Length 1 mm. 

 Breadth 0*75 mm. 



$ Puparium pale yellow, pellicle straw-coloured : narrow elongate, 

 with parallel sides and rounded extremities. Posterior half depressed, 

 with indistinct median carina. Length 0*80 mm. 



Adult 9 pale yellow. No parastigmatic glands. Pygidium (fig. 

 28) with six broad irregularly serrate lobes. Squames elongate, 

 narrow, with extremities very obscurely fimbriate : two in each 

 interspace between the lobes, and two or three beyond. A few 

 similar squames on margin of last abdominal segment. Semi-lunar 

 pores small, rather inconspicuous, three on each side. Near the base of 

 pygidium, on each side, is a small rounded prominence homologous 

 with the rudimentary fourth lobe occurring in some other species of 

 Parlatoria. Anal aperture central. Circumgenital glands in four small
