to some other insect. It is by no means unusual to find two or more 

 distinct species occurring together on the same plant. 



The ? scale (figures i and 2) and the extremity of the pygidium 

 (figure 3) are figured herewith. The central boss and raised circle 

 are conspicuous in the early stages, but become more or less obliter- 

 ated on the scale of the adult insect. The remarkable stalked pro- 

 cesses, immediately following the lobes on each side, are characteristic 

 of this species. 



4. Aspidiotus orientalis Newst. — Occurred abundantly on leaves 

 of Cycas revoluta at Calcutta. 



5. Aspidiotus these. Mask.— Dr. Watt has found this species on 

 tea throughout the Kangra Valley. He considers that it is confined 

 to that district, and is replaced in Assam by Aspidiotus camellia; 

 which does not appear to occur in Kangra. 



6. Fiorinia thea? } n.sp. (plate 1, figures 4 to 8). — When this insect 

 was first submitted to me I supposed it to be merely a local form of 

 the world-wide F. fioriniae. A more critical examination shows me that 

 it is quite distinct. It differs from jiorinide in the absence of lateral 

 lobes on the pygidium : in the form of the antenna which has no stout 

 spine ; and in the presence between the antennae of a proboscis-like 

 projection. The scale also is larger, stouter and more opaque. I 

 now describe the species under the name of F. these. 



Female puparium (fig. 5) consisting of the indurated pellicle of 

 the second stage which completely encloses the adult insect and is 

 without any secretionary margin. Elongate; narrow; with a moderately 

 distinct median longitudinal carina. Colour bright castaneous to dark 

 ferruginous brown, median longitudinal area darkest : opaque ; not 

 revealing the form of the insect beneath. First pellicle colourless or 

 very pale yellow ; projecting from anterior extremity of scale. Length 

 1*25 to 1*50 mm. Breadth, 0*50 mm. 



Adult $ pale yellow; of normal form (fig. 6). Antennas close 

 together, on anterior margin ; each antenna consisting of an irregular 

 tubercle with a single curved bristle on one side. From between the 

 antennas springs a stout spatulate process (fig. 7) which is not 

 chitinous but of the same consistency as the surrounding parts of the 

 body. Margin of thorax and abdomen with a series of minute spinneret 

 ducts opening on to small conical tubercles, Pygidium (fig. 8) with 

 a conspicuous median cleft, on the margins of which are situated the
