by the body of the female. In the cavity, besides the 9 , is a quantity of 

 white secretion, breaking into short strap-shaped fragments. None of this 

 appears externally. There are also more hair-like white fragments, some 

 of which may be seen protruding from the produced tubular organs. This 

 white secretion is no doubt analogous to the ovisac, as in it I found larvae. 



The male scale is cylindrical, rather over i mill, long, dull dark 

 crimson. There is an anterior dorsal ridge, leading to a mid-dorsal 

 swelling. Hind end truncate. Front end with a largle hole, where the $ 

 has escaped ; or, when the <$ has not escaped, this is covered by a flat 

 lid or cap. 



The larvce, as observed in numbers on the bark of the twig, are 

 crimson, elongate, with the segmentation distinct ; sides with a longitu- 

 dinal furrow. Caudal hairs about fj length of body, free from secretion. 

 These hairs arise some distance apart, and immediately caudad of each is 

 a small elongated process or tubercle ; between these, and terminating 

 the body, is a short, white, opaque caudal stylus, which is distinctly bifid, 

 and no doubt consists of the anal hairs covered by secretion. This 

 arrangement is suggestive of Dactylopius. 



The last joint of each antenna bears two long hairs, longer than the 

 whole antenna ; this is also the case with the larva of Maskell's Carteria 

 melaleucce. 



The claws have short knobbed digitules ; and the tarsus presents the 

 usual pair of knobbed hairs, which are very long. The tibia seems quite 

 as long as the femur, and the tarsus is very little shorter than the tibia. 

 There are some short stiff hairs about the base of the legs. 



Maskell remarks (Indian Mus. Notes, Vol. II., No. i, p. 62), on the 

 almost invariable rule that in larval Coccidae the tarsus is longer than the 

 tibia. This, however, is not the case in Erischiton cajani, Mask. ; and a 

 further exception is presented by Tachardia, in which, at least in T. gem- 

 mifera and T. melaleucce, the tibia of the larva is slightly longer than the 

 tarsus. 



On placing some of the $ scales in soda, I found fragments of a 

 Chalcidid parasite, which seems to belong to the genus Aphycus. The 

 antennae present the following characters : Scape long, with an apparent 

 false joint near its base, its upper part zoned with brown ; pedicel about 

 twice as long as broad ; the following 6 joints moniliform, increasing 

 regularly in size, the first three joined together, the last three more 

 separated and bearing whorls of hairs. Club large, brown (the joint just
