CEkOl'LASTKS CISTUDIFORMIS. 41 



both at base and apex, and so large as to almost 

 obscure the claw ; those of the tarsi ordinary. 

 Spiracles (fig. 5) trumpet-shaped ; parastigmatic 

 glands minute. Dermis (fig. 4) with numerous cir- 

 cular pores, and a very faint tessellation. 



Test or pellicle of young adult female (fig. lib) 

 somewhat limpet-shaped, with one dorsal and eight 

 irregular square-sided marginal plates of pinkish wax ; 

 each of the six lateral plates with a single central, 

 more or less square, opaque, snow-white, projecting 

 appendage ; anterior plate with three, posterior plate 

 with two, much smaller and more pointed, all being 

 surrounded by a broad band of rich dark crimson, 

 which gradually shades off into the surrounding wax ; 

 dorsal plate with the central white appendage very 

 elongate, placed horizontally in young individuals, but 

 tilted anteriorly in older examples. 



Long, 3-3*50 mm.; wide, 1*50-2 mm.; high, 1*50- 

 2 mm. 



Young adult female (fig. 0) short, ovate; legs and 

 antennae well developed ; dermis transparent, except at 

 the region of the anal lobes, where it is more highly 

 chitinised. Anal cleft rather short ; anal lobes highly 

 chitinised and brown, form normal. Stigmatic spines 

 (fig. 9) conical, a few of the inner examples much 

 larger than the rest ; the whole group numbers about 

 eighty, and occupies an extended triangle immediately 

 within the margin. Marginal hairs (fig. 9 a) simple 

 and minute. 



Long, 1*25-2 mm. ; wide, 1-1*50 mm. 



Test or pellicle of fully-developed larva (fig. 12) 

 with the same number of plates as in the young adult 

 female, but the wax is of a rich dark crimson, and the 

 opaque white appendages are larger and more distinct. 



Long, 11*25 mm. 



Habitat (under glass). On an orchid (Chrysis 

 b,-desc<>m) at Tring Park, the seat of Lord Rothschild, 

 father of the Hon. Walter Rothschild, to whom I am
